- 1 small red onion, thinly sliced
- 1 cup cherry tomatoes, halved
- 4 garlic cloves, minced
- 1 cup crushed tomatoes
- ½ cup heavy cream

How to Make Creamy Garlic Tomato Baked White Fish
- Preheat the oven.
Set your oven to 200°C / 400°F. - Prepare the vegetables.
Spread the thinly sliced red onion and half of the halved cherry tomatoes across the bottom of a baking dish. - Add the fish.
Arrange the white fish fillets over the vegetables. Season evenly with salt, black pepper, paprika, and Italian seasoning. - Add garlic and lemon.
Sprinkle the minced garlic around and over the fish, then arrange thin lemon slices between the fillets. - Prepare the creamy tomato sauce.
In a bowl, combine the crushed tomatoes, heavy cream, grated Parmesan, and olive oil. Stir until everything is well incorporated. - Pour in the sauce.
Pour the creamy tomato mixture around and lightly over the fish fillets. - Finish the dish.
Scatter the remaining cherry tomatoes around the fish and sprinkle a little additional Parmesan over the top. - Bake.
Bake uncovered for 18–22 minutes, or until the fish is opaque, flakes easily with a fork, and the creamy tomato sauce is bubbling around the edges. - Garnish and serve.
Spoon some of the warm creamy garlic tomato sauce over each fillet and finish with freshly chopped parsley.
What Type of White Fish Should I Use?
Several types of mild white fish work beautifully in this recipe. Cod, haddock, pollock, tilapia, or halibut are all good choices.
Thicker fillets may require a few additional minutes of baking, while thin fillets can cook more quickly.
Tips for Perfect Baked Fish
Pat the fish dry with paper towels before seasoning it. Removing excess moisture helps prevent the creamy sauce from becoming watery.
Try to choose fillets of similar thickness so they finish cooking at approximately the same time.
Most importantly, avoid overcooking the fish. It’s ready when the flesh becomes opaque and separates easily into moist flakes. For food safety, fish should reach an internal temperature of 145°F (63°C).
How to Make the Sauce Extra Creamy
For an even richer sauce, add a little extra Parmesan during the final few minutes of baking.
If the sauce seems too thick before baking, you can stir in a small splash of cream or broth. If you prefer a thicker finished sauce, allow the baking dish to rest for several minutes after removing it from the oven.
What to Serve with Creamy Garlic Tomato Fish
The creamy tomato sauce makes this dish perfect for serving with steamed rice, pasta, mashed potatoes, roasted potatoes, or couscous.
Crusty bread is another excellent option because it can soak up the extra garlic-Parmesan tomato sauce.
For a lighter dinner, serve the fish alongside steamed broccoli, green beans, asparagus, or a simple green salad.
How to Store Leftovers
Allow the fish to cool before transferring it and the sauce to an airtight container. Store in the refrigerator for up to 2–3 days.
Reheat gently until warmed through. Avoid excessive reheating because white fish can become dry and lose its delicate texture.
