Equipment
- Large rimmed baking sheet or roasting pan
- Parchment paper or aluminum foil
- Sharp chef’s knife (for scoring the fish)
- Cutting board
- Paper towels (for drying the fish thoroughly)
- Citrus knife or slicer (for thin lemon slices)
- Small mixing bowl (for seasoning mixture)
- Basting brush (optional)
- Instant-read thermometer
Ingredients
- 2 whole tilapia about 1–1½ pounds each, cleaned and scaled
- 3 tablespoons olive oil
- 4 cloves garlic minced
- 1 large lemon thinly sliced
- 2 tablespoons fresh rosemary chopped
- 2 tablespoons fresh thyme leaves
- 1 teaspoon sea salt
- ½ teaspoon freshly cracked black pepper
- ¼ teaspoon paprika optional, for color
- 2 tablespoons chopped fresh parsley for garnish
- Optional: 1 tablespoon capers
Instructions
- Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease a roasting pan.
- Prepare the fish. Pat the tilapia completely dry with paper towels. Using a sharp knife, score each side of the fish with 3 shallow diagonal cuts.
- Season the cavity. Stuff each fish with lemon slices, rosemary, thyme, and a little of the minced garlic.
- Season the outside. Rub olive oil all over both fish, including inside the slits. Sprinkle evenly with salt, pepper, paprika (if using), and remaining garlic.
- Roast. Place fish on the prepared pan and roast for 20–25 minutes, or until the flesh flakes easily with a fork and internal temperature reaches 145°F.
- Optional broil. Broil for 1–2 minutes at the end for extra crispy skin, watching carefully.
- Finish and serve. Garnish with fresh parsley and capers. Serve with extra lemon wedges and a drizzle of olive oil.
Notes
- How to make crispy skin whole roasted tilapia: The key to crispy skin is patting the fish completely dry before seasoning. Moisture prevents browning. Roasting at 425°F helps render the skin and create that golden, slightly crisp texture.
- Internal temperature for whole tilapia: Whole roasted tilapia is done when the thickest part reaches 145°F and the flesh flakes easily with a fork. Overcooking can make the fish dry.
- Do you eat the skin on whole tilapia? Yes, the skin is edible and delicious when roasted until crispy. Make sure the fish is properly scaled before cooking.
- Can I use dried herbs instead of fresh? Yes. Substitute 1 teaspoon dried rosemary and 1 teaspoon dried thyme for the fresh herbs if needed. Fresh herbs provide brighter Mediterranean flavor, but dried herbs work well for convenience.
- How to prevent whole fish from sticking: Use parchment paper or lightly oil the baking sheet. You can also place lemon slices under the fish to act as a natural rack.
- What to serve with Mediterranean whole roasted tilapia: Pair with roasted potatoes, lemon rice, couscous, grilled vegetables, or a simple Greek salad for a complete Mediterranean dinner.
- How to store leftovers: Store leftover tilapia in an airtight container in the refrigerator for up to 2 days. Flake leftover fish into salads, tacos, grain bowls, or pasta.
- Can I roast whole tilapia ahead of time? This recipe is best served fresh, but you can prep the fish (clean, dry, and season) up to 6 hours in advance and refrigerate until ready to roast.
