Crab-Stuffed Portobello Mushrooms
Crab-stuffed portobello mushrooms can do double duty as a tasty starter for a casual dinner party, or a light main course for two.
The concept for this recipe came from a family friend who used to make an appetizer with store-bought crab cakes that she crumbled and stuffed into mushroom caps.
Key ingredients:
We find that it’s just as easy (and more economical) to mix up a simple homemade crabmeat stuffing instead. Here’s what you’ll need:
- Cooked, pasteurized crabmeat (see below for shopping tips)
- Mild shredded cheese (Muenster or Monterey Jack)
- Panko crumbs
- Egg
- Lemon juice
- Fresh thyme
- Onion
- Garlic
Serving suggestions:
Our crab-stuffed portobello mushrooms can be served either as a first course or as a light dinner with a salad on the side. A light, food-friendly white wine like dry Riesling or Viognier is a nice pairing with this dish.
As written, this recipe serves two as a main course or four as an appetizer.
Shopping for crabmeat:
When buying crabmeat for this recipe, we recommend using the canned, pasteurized version found in the refrigerator case of your supermarket.
Most stores carry three or four varieties, any of which will work for the crab stuffing for these mushrooms. Here’s a rundown of the different types going from most to least expensive.
- Jumbo lump: Jumbo lump crabmeat comes from the rear section of the crab that’s attached to the legs it uses for swimming. The pieces are large, delicately flavored and carry the highest price tag of the four varieties mentioned here. For a recipe like this one, where you mix the crab with other ingredients, jumbo lump is not worth the extra cost.
- Lump: Lump crabmeat comes from the central part of the crab that’s attached to the claws. It has the same delicate flavor as jumbo lump, but the pieces are smaller. It’s a good choice for both this recipe and our Linguine with Crab.
- Backfin: Backfin is crabmeat from the body of the crab. The flavor is a bit stronger than lump, and the pieces are generally small. Backfin is a good choice for these crab-stuffed portobellos, as well as crab cakes and crab dips.
- Claw: Crabmeat from the claws is darker in color, slightly oily, and has a stronger flavor than the previously mentioned varieties. Use claw meat for recipes like soups, stews, and bisques, where a bold crab flavor is desirable.

Instructions
- Preheat the oven to 375°F and coat a shallow baking pan with nonstick spray.

Hello!
These look fantastic. I was wondering though how many ounces for each mushroom? I found a 2 pack and they are about 7 oz each. Are those the ones you used?
Hi Nicole,
Most portobello mushroom caps weigh 3 to 3-1/2 ounces each, so yes, you absolutely have the right size.
Hi, weird question but any way to do on the stove top with a grill pan? I bought all the ingredients but my oven broke..
Hi Kimberly,
Truthfully I think you’d be better off with a regular frying pan than a grill pan, but here’s what I think you could try:
Brush your frying or grill pan with a little oil, add your portobello caps and cook over medium-high heat for about 2 minutes per side to tenderize them, then set aside.
Combine the remaining ingredients and form the mixture into crab cakes that are about the diameter of your mushrooms. Add some more oil to the pan and fry them until golden, maybe 2 minutes per side. The tricky part here is keeping the crab mixture holding together as a crab cake. If they don’t stick and you’re careful turning them it should work out.
Once they’re lightly browned, carefully press them into the mushroom caps, then put them back in the pan, filling side up. Add a little extra cheese on top, cover the pan and cook over medium heat for another 3 minutes or so.
Good luck!
Do you publish a cookbook?
Hi Kevin,
We don’t publish a cookbook at this time, but all our recipes are easily printable. Thanks for asking!
My husband and I loved this recipe. Next time I plan on adding some Dijon mustard. Thank you for sharing.
Hi Judi,
Glad to hear you liked the recipe. I think adding Dijon is a great idea. It would blend nicely with the lemon and add a little extra punch. Thanks!
Wish you had given size of the mushrooms..
Hello Holly,
Sorry for that omission. Most portobello mushrooms are about four inches in diameter.
It was fabulous, big hit with even my husband who doesn’t like cooked mushrooms. We made on the BBQ – too hot for oven. Thankyou!!
Love this recipe – it goes over big as an appetizer ! It disappears quickly.
Hi Bette,
So glad you liked the recipe. We appreciate you taking the time to let us know.
Can you prepare the night before and then put in the oven or should it be prepared on the same day?
Hi Jonathan,
This is what I would do for best results: Clean the mushroom caps as directed, but don’t salt them. Store them in a paper bag in your refrigerator’s vegetable crisper. Prepare the stuffing as directed, grate the cheese and refrigerate both separately. About a half hour before you’re ready to serve, preheat the oven, season the mushrooms, stuff and bake according to the directions. Hope you enjoy!
I tweaked the recipe a bit,I switched the thyme with cilantro and the muenster cheese with pepper jack and to the stuffing mixture i added some Dave’s insanity sauce.It turned out PERFECT!
Hi Brent – You gave the recipe a nice twist – a bit of a Mexican flare. Great idea! Thanks for sharing it with us.
can I substitute another seafood for crab…. minced clams?
Hi Ruthann,
Yes, I do think you could use minced clams (well drained). You could also pre-cook some shrimp, scallops or a mild white fish like tilapia, chop it fine and use that in place of the crab. If I was going to pick an alternate, I think my top choice would be the fish, but I’d love to hear what you choose and how you like it.
Do you drain the crabmeat if canned?
Hi Niki,
Yes, you do want to drain the crabmeat.
I am making this tomorrow for lunch!! I just bought all of the ingredients tonight at the grocery store. I have been waiting patiently all week to get my paycheck and go shopping. I can’t wait. It looks absolutely delicious!!
Thanks Amanda! I hope you enjoy them.
I definitely enjoyed them! They were delicious. I hate to change recipes but I had to substitute the bread crumbs for a gluten free kind; because I am intolerant of gluten. But the rest of the recipe i kept unaltered. It was worth the trip to the grocery store.
So glad you enjoyed the recipe!
Glad I found this on line as I left all my old recipes when I moved abroad. This is fantastic as a first course or for part of a main meal. It is particularly good if any of your guests do not eat meat. I agree with the comment about not overdoing the cheese as it really is more of a light binder but if you have to use fake crab and depending on where you are, you may. Vary the flavor with fresh herbs such as tarragon.
I just happen to have a container of crabmeat in the fridge and will be trying this very soon.
Very nice flavor. I was searching for something that fits a diet we follow for health reasons. This was perfect.
Newcomer to ur site. Looks fab. Will keep it handy.
Thanks
