Oven Baked Fish and Vegetables

Why I’ll Love This Recipe

I love that everything cooks together on one pan for easy cleanup.

I enjoy how the fish stays tender while the vegetables become perfectly roasted.

I appreciate that this recipe is healthy, wholesome, and full of fresh flavors.

I like that I can use a variety of seasonal vegetables depending on what I have available.

I find that it is quick enough for weeknight dinners while still being elegant enough for guests.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• white fish fillets (such as cod, haddock, halibut, or tilapia)
• broccoli florets
• zucchini, sliced
• bell peppers, sliced
• cherry tomatoes
• red onion, sliced
• olive oil
• garlic, minced
• lemon juice
• lemon slices
• Italian seasoning
• paprika
• salt
• black pepper
• fresh parsley, chopped (for garnish)

Directions

1. I preheat the oven to 400°F (200°C) and line a large baking sheet with parchment paper or lightly grease it.
2. I place the broccoli, zucchini, bell peppers, cherry tomatoes, and red onion on the baking sheet.
3. I drizzle the vegetables with olive oil and season them with garlic, Italian seasoning, paprika, salt, and black pepper before tossing everything together.
4. I roast the vegetables for about 15 minutes so they begin to soften.
5. I remove the baking sheet from the oven and place the fish fillets among the vegetables.
6. I drizzle the fish with olive oil and lemon juice, then season it with a little more salt, pepper, and paprika.
7. I place lemon slices over the fish for extra flavor.

9. I garnish everything with freshly chopped parsley before serving.

Servings and Timing

Variations

I sometimes use salmon instead of white fish for a richer flavor.

I enjoy adding asparagus, carrots, Brussels sprouts, or green beans depending on the season.

I like seasoning the fish with Cajun seasoning or lemon pepper for a different flavor profile.

I occasionally sprinkle grated Parmesan over the vegetables during the last few minutes of baking.

I sometimes add a few sliced potatoes, roasting them first since they require a longer cooking time.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 2 days.

I reheat the fish and vegetables in a 325°F (165°C) oven until warmed through to help preserve the fish’s texture.

I avoid overheating the fish because it can become dry.

I do not recommend freezing this dish since the vegetables and fish may lose their texture after thawing.

FAQs

What type of fish works best for this recipe?

I enjoy using cod, haddock, halibut, or tilapia because they bake beautifully and have a mild flavor that pairs well with roasted vegetables.

Can I use frozen fish?

Yes. I thaw the fish completely and pat it dry before baking to help it cook evenly and prevent excess moisture.

How do I know when the fish is done?

I check that the fish flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Can I use different vegetables?

Yes. I often use whatever fresh vegetables I have available, including asparagus, cauliflower, mushrooms, green beans, or Brussels sprouts.

Can I prepare this meal ahead of time?

Yes. I chop the vegetables and prepare the seasoning ahead of time, then assemble and bake everything just before serving for the freshest results.

I enjoy making Oven Baked Fish and Vegetables because it is a simple, nutritious, and flavorful meal that requires very little effort. The tender, flaky fish and perfectly roasted vegetables create a balanced dinner that is both satisfying and easy to customize.
