Garlic-Herb Crusted Boneless Pork Sirloin Roast
This tender, juicy boneless pork roast is coated in a delicious rub made with extra virgin olive oil, garlic, fresh herbs, and orange zest.
We love to make pork roast for a company meal because it adapts beautifully to a wide variety of seasonings and sauces, and it always yields great results.
About the ingredients:
Boneless pork sirloin:
Boneless pork sirloin roasts cook fairly quickly, are easy to carve, and when done to the proper internal temperature, turn out tender, juicy, and full of flavor.
This cut generally weighs between 2-1/2 and 3 pounds, enough for about 6 servings. It’s a great choice for smaller gatherings, or if you’re short on time or oven space.
If you’re having a larger group, simply cook two roasts side by side.
Garlic and herb rub:
Our Italian-inspired garlic and herb rub is made by combining extra virgin olive oil with:
- Pressed garlic
- Kosher salt
- Ground black pepper
- Orange zest
- Fresh rosemary
- Fresh thyme
- Fresh sage
It’s fabulous on both this boneless pork roast and its fancier cousin, the crown roast. Learn more about cuts of pork from pork.org.

We’ve paired this flavorful entrée with make-ahead accompaniments like stuffed mushrooms for an appetizer, baked pasta and green bean casserole side dishes, and biscotti for dessert.
- Spinach Stuffed Mushrooms
- Parmesan Pasta with Cabbage and Thyme
- Green Beans and Tomatoes Oreganata
- Orange Rosemary Biscotti

Any recommendations for sides to compliment this roast?
Hi Elizabeth,
I have a few suggestions for you:
– Scalloped Potatoes
– Parmesan Pasta with Cabbage and Thyme
– Oven Roasted Brussels Sprouts
– Garlic and Herb Roasted Cabbage
Hope this helps – thanks for asking.
My boneless pork sirloin roast is only a pound so will this recipe work for it. Plan to make polenta with it so I want drippings for gravy. Sounds delicious from all the comments.
I’ll pass on the drippings for the graveyard!! LOL
Hi Mary,
You have a keen eye – LOL. I don’t normally edit people’s comments, but I’ve fixed that. Not sure how I missed it the first time.
OH MY GOODNESS! This recipe was the answer to my dilemma; I had purchased an inexpensive cut of pork roast because it was one of the last fresh pork offerings at my local grocery store. After much searching, I came across this recipe which was exactly what I was hoping to produce when i brought the roast home. My dear husband of 41 years is slow to compliment my cooking- but this recipe caused a praise parade!! I followed the instructions and proportions exactly as stated and it truly delivered perfection! Thank you for restoring marital bliss during a challenging pandemic quarantine time. Thank you so much for such a simple recipe to a juicy, super flavorful and tender little sirloin pork roast on a weeknight. I am extremely pleased and will share with my discerning daughters as well!
Hi Kelly,
Thank you for all the kind words. These are challenging times and getting exactly what you want at the grocery store isn’t always possible. I’m glad this recipe solved a problem for you. Stay well!
Can I substitute dry herbs for fresh and what would be the difference in measurements?
Hi Rona,
Because dried herbs are more potent than fresh, the general rule of thumb is to use only 1/3 the quantity called for in the recipe. For this particular recipe, I would use 1/2 teaspoon each of dried rosemary and thyme, and a scant 1/2 teaspoon on the sage. If you don’t have any fresh orange zest, replace 1-1/2 teaspoons of the olive oil with orange juice in the rub mix.
Mentioned browning the roast,before cooking in the oven
How do u do this with the string on
I would like it to have a crust, but not over done
Thank you
New cook on board
Thank you
Hi Susie,
There is no problem with browning the roast after it’s been tied. Just be sure to use kitchen twine and it will hold up just fine.
I don’t have a roasting pan with a tray, would a broiler pan work with the water underneath? Or would you suggest something different?
Sounds amazing ❤️
Hi Jerri,
I think the broiler pan will work out just fine. The roast may not brown up as much on the bottom as it would on a rack, but that’s not an issue.
If you have the type of cooling rack you use for cakes, that would work too. Just spray it well with nonstick spray and set it inside the bottom of your broiler pan.
Hope that helps.
While I have not yet made this recipe, I received my Butcher Box pork loin today and plan on using this recipe. I just wanted to say that this is my first visit to your site and it is wonderful to see how responsive you are to your readers’ queries and commnts! I am looking forward to making this and may just follow the advice to make slits in the roast and fill with garlic paste. Thank you!
Hi Cheryl,
Thanks for taking the time to leave a comment. It’s so nice to have you as a visitor. Regarding Butcher Box – we really like the quality of their pork too, and I’m sure your roast will turn out great. Stuffing garlic into slits in the roast will definitely infuse extra flavor. Let us know how you like it.
I made this and it was delicious and easy. Not dry at all. Will make great left overs.
Hi Laura,
I’m glad you enjoyed the pork. Thanks for taking the time to comment and let us know.
Found this recipe through our Butcher Box membership and made it for New Years Day dinner. It was absolutely delicious – even my 7 year old complimented me on the flavor and juiciness of the meat! Thank you for sharing this recipe!
Hi Megan,
I’m so glad you and your family enjoyed the pork roast recipe. Sounds like your 7 year old is destined to be a real foodie – that’s great!
Being of Serbian descent and married to a Croatian, I do cook a lot of pork roasts and lamb. Pork can safely come out of the oven when the internal temp is 145 on a meat thermometer. Tent it loosely with aluminum foil and let it rest 15 minutes or so, so that the juices redistribute to keep the meat moist. Also, the temp goes up a bit (called carry-over cook time) while it is resting. The meat may be slightly pink on the inside, but is perfectly safe to eat, or we would all be dead by now! It is not the same as pork was 40 years ago. That’s why the commercials say “Pork – the other white meat”
Hi Michelle,
You’re right, pork is very different than it was years ago and that internal temp of 145°F is not only safe, it ensures that the meat stays juicy and moist. Thanks for sharing the info.
I had never made a Pork Sirloin Roast and was terrified as I had heard it was a tough cut of meat. But, I followed the directions with the exception of “fresh” spices (there is not a store within 50 miles to get those). The meat came out perfectly. It was juicy and tender, and the flavor was excellent. I did, however, cook the meat to 155 degrees as I am a Nervous Nelly when it comes to pork. Even so, the meat was still tender and juicy. THANK YOU for posting the recipe.
Hi Dorilea,
You can certainly season your pork roast with anything you’d like – including plain old salt and pepper. I’m glad to hear that the cooking method produced a tender, juicy pork roast for you. Thanks for letting us know.
We have a pork loin sirloin roast. Would this recipe work for this cut of meat. I only cooked this cut once and found it very dry and tough and no flavor, I did use spices on top. (. even though I had removed it at temp of 145). If the recipe will not work, please let me know how to cook this meat.
Hi Judy,
This recipe is intended for a 2-1/2 to 3 lb pork sirloin roast (5 to 6 servings). We’ve always had good results with it and I’m hoping you will too.
There are two steps in our recipe that are important for keeping the meat moist and juicy. The first is that you bring the roast to room temperature before cooking so it doesn’t take too long to reach that internal temperature of 145°. The second is to position the roast on a rack inside your roasting pan and add water as instructed. This will create moist heat inside the oven and help to prevent the meat from drying out.
It’s a good idea to roast meat in a pan that’s fits it fairly well. You don’t want the meat touching the sides, but you don’t want the pan to be so large that your juices evaporate quickly or burn. Pork sirloin roasts aren’t too big, so you may have better luck using a straight-sided baking dish as opposed to a large roasting pan.
Another tip is to shop for a roast that has a little visible marbling and layer of fat on top. If you look closely at our photo, you’ll see that thin layer of fat on the top. This not only goes a long way toward keeping the meat moist it adds flavor too. Hope this info helps!
I bought a pork sirloin not knowing anything about it. Followed this recipe and it was amazing. Many, many thanks.
Hi Denise,
So glad you enjoyed the recipe!
I want to try this today but I have a question. After placing the water in the roasting pan, do I cover the roast with the lid to the roasting pan? I see the recipe then says “remove from oven and tent loosely with foil”. Does that mean I didn’t have a cover on the meat previously?
Hi Chris,
Thanks for getting in touch. Yes, you want to roast the pork uncovered. Once it reaches the internal temp of 145° you can take it out of the oven and tent some foil over it loosely while it rests before carving.
Would I be able to do this in the crockpot? If so, would you suggest any ingredient amoount changes and how long do you think? Thanks, looking forward to trying this!
Hi Lindsey,
I’ve never made this in the crockpot, but here’s how I would do it:
Season the roast liberally with salt and pepper brown it in a skillet on all sides. Place it in the crockpot, then sauté the garlic in the pan drippings just until soft – not browned. Add the thyme, sage and orange zest and spread the mixture over the top of the roast.
Omit the rosemary at the beginning because it tends to get bitter when cooked for a long time. You can add a whole sprig during the last 20 minutes of cooking and for some subtle some rosemary flavor.
Pour in 1/2 cup of liquid. Try a combination of low-sodium or homemade chicken broth and orange juice to bring out the flavor of the orange zest a little more. You could also use white wine if you prefer.
Cooking time is where I’m not too sure. You still want to bring the roast to an internal temperature of 140° to 145° but pork can get very dry in the crockpot, so I would say 4 hours on low should be more than enough to cook a boneless roast like this yet keep it tender. I will depend on the crockpot to some degree too.
Your question has piqued my curiosity and I’ve added a crockpot version of this roast to my recipe to-do list. Let me know if you try it. I’d love to hear how you make out.
Hi, I have been cooking pork loin for several years. I use a crock pot and cook on low for 6-7 hours. I spice the meat with salt, pepper an garlic powder.then brown it in a cast iron skillet. Place the loin on a bed of sliced onions and let it cook.It falls apart and you can use it as a meal with potatoes and gravy and a veggie. You can add potatoes, carrots, celery about anything. It all get done at the same time put the veggies in with about 2 hour left to cook. I like to shred mine and I use it to make burritos or enchiladas. It is great with New Mexican red chile..
I did try this in the crockpot and it didn’t turn out as well as the oven. I wouldn’t make it in the crockpot again.
Hi Elizabeth,
Thanks for letting us know about your experience. I think it’s tough to get great results from the crockpot with a leaner cut of pork like a sirloin roast.
The recipe was great! I cut slits into the top of the roast and stuffed it with pressed garlic and I slathered it with salt and pepper prior to adding the rub. Only down side is my roast was 2.2lb and only half of it was cooked when I cooked it for 55 min and the internal temp reached 145 degrees. The bottom half was rare. I do not have a roasting pan so I used a pan and a cooling rack to set it on top. That may have been part of the problem. =/ I would love to try this recipe again, but maybe with a smaller roast and with an actual roasting pan.
Hi Luz – Thanks for sharing your experience. Roasting pans do have low sides that allow for better heat circulation around your meat, but in lieu of getting a new pan, you could try roasting the pork bottom side up for about 20 minutes, then turn it right side up to finish cooking. You can also rotate the pan when you put it back in the oven. Allow 3 or 4 minutes extra to compensate for the heat loss from opening the door as well. Hope this helps!
This was fantastic! I also used dried herbs because I didn’t feel going to the store. I also used lemon zest instead of orange because I had it. We loved this!
Thanks Elizabeth! So glad you enjoyed it.
Absolutely AMAZING, flavorful, delicious, juicy, aromatic, INCREDIBLY EASY recipe. My only substitutions were I doubled the garlic, since there’s no such thing as “too much garlic”, and I used dried sage…about 1tsp. The other herbs and orange zest were fresh. ..actually I probably used more like 3 tsp zest…the whole zest of a small orange. ..because I like citrus too!! My roast was just about 2 lbs …we had roasted asparagus and my husband had a baked potato, and there is enough of the roast for tomorrow nights dinner…by the way…this is the first time I felt impressed enough with a recipe to take the time to write a review. TO ANY NEWBIE COOKS, TRY THIS!!
I made this for New Years dinner. I ordered a 6 1/2# roast from my butcher, which was actually 2 small roasts tied together. I doubled the ingredients for the rub, cooked it to 145 degrees which took about 2hrs & 10 min. My house smelled fantastic (used all fresh herbs except the sage, used a little less than recipe called for since it was dried), the roast was moist & delicious and I’ll definitely be making this again! Thanks for a fantastic recipe!!
Hi Jann,
So glad you enjoyed the pork roast – I’ll bet it did smell great. Thanks for letting us know the quantities and cook times for a larger roast. Your feedback is much appreciated. Happy 2015!
I have two roast weighing 2.6 lbs. each. They are fresh pork sirloin roast. They have a small bone on one side and I can’t tell if it goes all the way through. Do I cook them the same way as boneless?
Hi Sue,
Without seeing your roasts, it’s a bit hard for me to weigh in, but I think you can proceed with the recipe as written for the most part. Since the roasts only weigh a little over 2.5 lbs with a bone included, you should probably start checking the internal temperature a little sooner – perhaps after 45 minutes in the oven. Be sure to stay clear of the bone with the thermometer though, as you won’t get an accurate reading if it’s touching.
I use fresh rosemary and herbes de Provence since I always have a bottle in the house. I also make a sauce of canned, or fresh, cranberries, caramelized onions, rosemary and balsamic vinegar, which I serve on the side. Really wonderful recipe!
Sounds delicious Susan. The herbes de Provence would be a nice touch. Thanks for sharing.
DELICIOUS!! I love the way the herbs just hang out in you mouth for awhile. We will definitely have this again.
Thanks Debbi – glad you enjoyed it!
This is absolutely the most wonderful pork roast I’ve every prepared of eaten. My boyfriend was so impressed with it that I make it weekly and usually prepare tow of them together. Phenomenal!
Thanks for your comment – we’re so glad you like the recipe.
just looking at this is making me hungry
I am going to try this recipe. I have a larger group and want to take your advice and cook two roasts side by side. Does the cooking time change? Or will two roasts cook in the same amount of time?
Actually, one roast is 2 lbs. and the other is 2.5 lbs.
Hi Kari,
The cooking time for 2 roasts should be very close to the 55-75 minute range specified in the recipe for a single roast. Every oven is different though, so the most important thing to do is check them with an accurate meat thermometer inserted into the thickest part of the roast.
Since one of your roasts is a bit smaller than average, you should probably check it after 45 minutes, then check the larger one 10 minutes later. If they aren’t quite done, put them back in the oven and check every 7 minutes or so until the temperature reaches 145°.
Enjoy!
So delicious! This will be my go-to rub for pork from now on. My cut was only 1.5 lbs. but it still took 75 minutes to reach 145 degrees. I made a simple gravy from the pan drippings by bringing it to boil with some flour. We served it with mashed potatoes for a birthday dinner. Thanks!!!
I agree with Janine–this is the best pork roast we’ve ever had! I made a few modifications, mostly that I didn’t read ” fresh” herbs and used a dry mixture of herbs, cutting down the amount, and I didn’t have enough orange zest. I agree with Stattick about the strong aroma while baking, so I’ll try fresh next time. I couldn’t believe it’d be done in such a short length of time, but it was done in 1 hour, and after the foil tent, it was perfection (my roast was only 2 lbs.). Thanks!
I made this tonight for my daughters birthday and let me just bow down to you. So simple yet classy and delicious. Thankyou for this wonderful recipe
the most delicious pork we have ever eaten. YUM!
This was a terrific roast recipe. I didn’t have citrus but used Lawry’s Montreal steak seasoning & added worcestershire sauce to the mix. Made a really lovely pan gravy.
Is 145 degrees enough? Just wondering, because that is the lowest recommended temp I have ever seen for this cut of pork. I realize pork doesn’t need to be cooked to death (like it was believed in the past), but it is my understanding that 155 degrees may be a better number.
Hi Don,
Thanks for your comment. The internal temperature of the roast will continue to rise from 5° to 10° as it rests before carving. This will bring the temperature to at least 150°F, more likely a little higher. This is considered medium doneness for pork.
If you prefer your pork well done, remove it from the oven when the internal temperature is 150° or 155°.
Hope this info helps!
I’m mincing herbs right now to combine with olive oil for my roast. I’m going to refrigerate it with the marinade overnight and roast for Sunday dinner. Alongside will be featured roast turnips, parsnips, and carrots (root vegetable medley) mashed potatoes, and a rich pan sauce from the drippings! Can’t wait to taste this one!
I tried this for Christmas dinner for my girlfriend and I (just the two of us). I didn’t have fresh herbs, just the dried stuff. After hunting around, I found that most of the fresh herbs substitute for dried by halving the amount, but a few of them substitute by a third. I only had table salt, and cut the salt total by half. I only had canola oil, and used the amount asked for. I didn’t even have pepper corns, so used course ground black pepper. I even had to substitute the orange zest for dried orange peel. So really, the only thing I had that didn’t require substitution was the garlic. 😛
My roast was only 2 lbs, so I then cut everything by a third. I figured that there’d just be way too much salt and herbs for a two pound roast, when the recipe was designed for a roast near to two and three quarter pounds. The herbs, for the most part, didn’t divide evenly by then, so I just cut a 1/4 of a teaspoon from all of them, cutting 3/4 down to 1/2, and 1/2 down to 1/4.
The roast… didn’t really smell all that great while it was cooking. Honestly, it just didn’t. It didn’t smell awful, just pungent, almost like scorched garlic. Fresh herbs probably would have made all the difference in the world as far as the nose went.
But the roast was juicy, flavorful, and tasted wonderful. It was a great, savory pork roast, without all that sugery sweetness that everyone seems to want to slather pork with. I will definitely be making this again… and if I can figure out how to improve the aroma, I will. Maybe actual, fresh orange zest is the key – I’m suspicious of the age of what I used.
Glad the roast turned out well. Sounds like you had a good handle on the quantity adjustments.
