Instructions:

1. Preheat and Prep:
- Preheat your oven to 375°F (190°C).
- Halve the cherry tomatoes, dice the red bell pepper, mince the garlic, and chop the onion. Set these aside.
- Pat the white fish fillets dry with a paper towel and season them lightly with salt and pepper.

2. Cook the Vegetables:
- Heat a large skillet over medium heat and add a splash of olive oil.
- Add the chopped onion to the skillet and sauté for about 3-4 minutes until it becomes translucent.
- Add the minced garlic and cook for another 1-2 minutes, being careful not to let it burn.
- Next, add the diced red bell pepper and cook for an additional 3-4 minutes until softened.
- Stir in the halved cherry tomatoes, season with salt and pepper to taste, and cook for about 5 minutes until the tomatoes start to break down and release their juices.

3. Add Seasoning:
- Pour in the 2 tablespoons of vinegar and stir to combine.
- Add the chopped basil (reserve a little for garnish if you like) and mix well. Let the mixture simmer for another 2-3 minutes to let all the flavors meld together.

4. Bake the Fish:
- Transfer the vegetable mixture (ratatouille) into an oven-safe dish, spreading it evenly across the bottom.
- Place the seasoned white fish fillets on top of the ratatouille.
- Drizzle a little more olive oil over the fish, and season with additional salt and pepper if desired.

5. Bake:
- Place the dish in the preheated oven and bake for 15-20 minutes, or until the fish is cooked through and flakes easily with a fork. The exact cooking time will depend on the thickness of your fish fillets.

Fish with ratatouille FAQ:

What is the best cooking time for the fish?

Bake the fish at 375°F (190°C) for 15-20 minutes, or until it is cooked through and flakes easily with a fork. The exact cooking time may vary depending on the thickness of your fish fillets.

How should I store leftovers of this dish?

Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or microwave until warmed through.

What type of white fish can I use in this recipe?

Suitable options include cod, tilapia, haddock, or any firm white fish you prefer. Ensure the fish is fresh for the best flavor.

Can I make substitutions for the vegetables?

Yes, you can substitute or add other vegetables such as zucchini, eggplant, or bell peppers based on your preference. Just keep in mind that this may slightly alter the dish's flavor.

What should I do if the fish isn't cooking evenly?

If the fish fillets are uneven in thickness, you can wrap thinner parts in aluminum foil to help them cook more evenly. Additionally, check for doneness at the 15-minute mark and adjust cooking time as needed.

Tips:

- Choose a firm white fish like cod or haddock to maintain the texture during cooking.

- For a richer flavor, marinate the fish in olive oil, lemon juice, and herbs for at least 30 minutes before cooking.

- Sauté the vegetables until they are tender but still retain some of their crunch for the best texture and flavor.

- Serve with a side of crusty bread or a light salad for a complete meal.
