Baked Fish with Tomatoes and Lemon Slices

This Baked Fish with Tomatoes and Lemon Slices is a simple, fresh, and flavorful Mediterranean-inspired dinner. Tender white fish fillets are baked with juicy cherry tomatoes, thin lemon slices, garlic, herbs, and olive oil until perfectly flaky. The tomatoes release their juices as they roast, creating a light and flavorful sauce that complements the delicate fish beautifully.

It is an excellent choice for a quick weeknight dinner, but the colorful presentation also makes it perfect for entertaining. Serve it with roasted potatoes, rice, couscous, or a crisp green salad for a complete meal.

Ingredients

For the Fish

  • 4 white fish fillets, such as cod, haddock, halibut, or tilapia
  • 2 tablespoons extra-virgin olive oil
  • 2 cups cherry tomatoes, halved
  • 1 lemon, thinly sliced
  • 4 cloves garlic, finely minced
  • 1 teaspoon dried oregano
  • ½ teaspoon dried thyme
  • ½ teaspoon paprika
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon red pepper flakes, optional
  • 2 tablespoons fresh parsley, chopped
  • 1 tablespoon fresh lemon juice

Optional Additions

  • ½ cup Kalamata olives
  • ¼ cup crumbled feta cheese
  • 1 tablespoon capers
  • Fresh basil for garnish

Preparing the Fish

Preheat your oven to 400°F (200°C). Lightly grease a large baking dish or line a rimmed baking sheet with parchment paper.

Pat the fish fillets dry with paper towels. Removing excess moisture helps the fish roast rather than steam and allows the seasonings to adhere properly.

Arrange the fish fillets in the prepared baking dish, leaving a little space between each piece.

Drizzle the fish with about half of the olive oil. Season evenly with oregano, thyme, paprika, salt, and black pepper. If you enjoy a little heat, sprinkle over the red pepper flakes.

Preparing the Tomatoes and Lemon

Place the halved cherry tomatoes around the fish. Add the minced garlic and drizzle the remaining olive oil over the tomatoes.

Arrange the thin lemon slices over and around the fish. The lemon slices will roast in the oven and release their fragrant citrus oils while adding beautiful color to the dish.

If using Kalamata olives or capers, scatter them around the fish at this stage.

Finish by drizzling fresh lemon juice over everything.

Baking the Fish

Place the baking dish in the preheated oven and bake for approximately 15–20 minutes, depending on the thickness of the fish fillets.

Thinner fillets may be ready closer to 12–15 minutes, while thicker pieces may require closer to 20 minutes.

The fish is ready when it becomes opaque and flakes easily when gently pressed with a fork. For food safety, fish should reach an internal temperature of 145°F (63°C).

Avoid overbaking because fish can quickly become dry. Start checking the fillets a few minutes before the expected cooking time is complete.

Once baked, carefully remove the dish from the oven and allow the fish to rest for about 3–5 minutes.

Finishing the Dish

Spoon some of the roasted tomato and garlic juices over each fish fillet. Sprinkle generously with fresh parsley.

For a Mediterranean-style finish, crumble a little feta cheese over the top. Fresh basil can also be added for extra freshness.

Serve the fish with the roasted tomatoes and lemon slices. The flavorful juices at the bottom of the baking dish can be spooned over rice, potatoes, or crusty bread.

Serving Suggestions

This baked fish pairs beautifully with many simple side dishes.

For a Mediterranean-inspired meal, serve it with lemon herb rice, couscous, roasted potatoes, or warm pita bread. A Greek-style salad with cucumber, tomato, red onion, olives, and feta also works wonderfully.

For a lighter option, serve the fish with steamed green beans, roasted asparagus, zucchini, or a simple mixed-green salad.

Crusty bread is especially useful for soaking up the delicious tomato, garlic, olive oil, and lemon juices left in the baking dish.

Helpful Tips

Choose fresh fish: Look for firm, fresh-smelling fillets with an even thickness. Cod, haddock, halibut, and tilapia all work well.

Dry the fish first: Patting the fillets dry helps the seasoning stick and encourages better roasting.

Slice the lemon thinly: Thin slices soften more quickly and release plenty of flavor during baking.

Don’t overcrowd the dish: Give the fish and tomatoes enough space so they roast properly.

Watch the cooking time: Fish cooks quickly, so check it early. Overcooking is the most common reason baked fish becomes dry.

Use fresh herbs: Parsley, basil, dill, or oregano can be added after baking for a brighter finish.

Add olives and feta: Kalamata olives and feta transform this simple recipe into a more traditional Mediterranean-style meal.

Recipe Variations

For a richer version, add a few small pieces of butter over the fish before baking.

For a spicy version, increase the red pepper flakes and add sliced fresh chili peppers.

You can also add thinly sliced zucchini, bell peppers, or red onion to the baking dish. These vegetables roast beautifully alongside the fish and absorb the flavorful juices.

For a heartier meal, place a layer of thinly sliced potatoes underneath the fish. Parboil the potatoes first so they become tender at the same time as the fish.

If you prefer a stronger Mediterranean flavor, add olives, capers, feta, oregano, and a drizzle of extra-virgin olive oil before serving.

Storage and Reheating

Store leftover fish in an airtight container in the refrigerator for up to 2 days.

To reheat, place the fish in a covered baking dish and warm gently in a 300°F (150°C) oven until heated through. Avoid reheating at very high temperatures because this can dry out the fish.

You can also enjoy leftover fish cold over a green salad or flaked into a grain bowl.

Nutrition Notes

This recipe provides a light source of protein along with vegetables, olive oil, tomatoes, and fresh lemon. Nutritional values will vary depending on the type of fish and the amount of olive oil, feta, and other optional ingredients used.
