While the main ingredients roast, we make an easy, Mediterranean-style topping to spoon over the fish fillets.
It’s a slow-simmered combination of garlic and olive oil with capers, fresh parsley and lemon juice added just before serving.
As with any sheet pan dinner, timing is key for this recipe. It’s important to start the zucchini and tomatoes ahead of the quick-cooking fish to let them caramelize so they develop their delicious, naturally sweet flavors.
We like to keep this meal low-carb, so we generally serve it with just a salad, but a side of garlic bread would be a great addition.
Mediterranean Sheet Pan Fish Dinner
- 1-1/4 to 1-1/2 lbs tilapia, or catfish, barramundi, snapper fillets
- Salt and freshly ground black pepper
- 2 tablespoons freshly squeezed lemon juice, divided
- 2-1/2 tablespoons olive oil, divided
- 6 cloves garlic, peeled and roughly chopped
- 1 lb zucchini, ends trimmed and quartered lengthwise (see notes)
- 8 plum tomatoes, ends trimmed and cut into 1/2-inch slices
- 2 tablespoons capers, rinsed and drained
- 2 tablespoons fresh parsley, chopped
- Preheat the oven to 425°F and coat a rimmed baking sheet with nonstick spray.
- Season the fish fillets on both sides with salt and pepper, drizzle with 1 tablespoon of the lemon juice and a bit of olive oil. Set aside.
- Add 2 tablespoons of olive oil to a small saucepan and place over medium low heat. Stir in the garlic and as soon as the oil begins begins to bubble cook for 30 seconds, then turn the heat down to low and continue cooking.
- Give the garlic mixture a stir occasionally to be sure the garlic doesn’t brown.
- Cut the zucchini quarters in half crosswise and arrange on the prepared baking sheet. Season with salt and pepper and roast for 5 to 7 minutes.
- Add the tomatoes to the baking sheet, season with salt and pepper and return the pan to the oven for an additional 10 minutes.
- Add the fish to the sheet pan and continue roasting for an additional 8 to 12 minutes, or until the fish flakes easily with a fork.
- While the fish cooks, add the remaining tablespoon of lemon juice along with the capers and parsley to the garlic and olive oil mixture. Turn up the heat for a minute to warm the mixture then set aside.
- Top each fish fillet with a portion of the garlic-caper mixture before serving.
