How to Make Herb Baked Fish with Rainbow Bell Peppers Recipe
Step 1: Prepare Your Oven and Peppers
Start by preheating your oven to 400°F (200°C), setting the stage for perfectly baked fish and roasted peppers. While it heats up, lightly grease a baking dish or line it with parchment paper to prevent sticking and make cleanup a breeze. In a large bowl, toss the vibrant sliced bell peppers with olive oil, minced garlic, dried thyme, basil, oregano, and a pinch of salt and pepper. This simple mix ensures the peppers will soften beautifully and soak up those incredible herb flavors as they bake.
Step 2: Arrange the Peppers and Fish
Spread the herb-coated bell peppers evenly in the prepared baking dish, creating a colorful bed for your fish. Carefully place the white fish fillets on top of the peppers in a single layer. Season the fish fillets generously with salt, black pepper, and the bright lemon juice. This step is key for that zesty kick that fully complements the mild flavors of your fish and the sweet peppers.
Step 3: Bake Until Perfect
Place the baking dish in the preheated oven and bake for 15 to 20 minutes, depending on the thickness of your fillets. You’ll know the fish is done when it flakes easily with a fork and the bell peppers become tender and slightly caramelized. Keep an eye on the oven so the fish stays moist and the vegetables don’t overcook.
Step 4: Garnish and Serve
Once baked, remove the dish from the oven and sprinkle fresh parsley over the top for a pop of green freshness. Serve your Herb Baked Fish with Rainbow Bell Peppers Recipe with lemon wedges on the side to squeeze over individual plates for an extra burst of light citrus flavor.
How to Serve Herb Baked Fish with Rainbow Bell Peppers Recipe

Garnishes
Fresh parsley is classic for a reason—adding a sprinkle just before serving brightens both the look and taste. A few lemon wedges enhance the dish further, letting each person tune the citrus level to their liking. For a bit of heat, consider a light dusting of crushed red pepper flakes or a drizzle of chili oil.
Side Dishes
This dish pairs beautifully with a variety of sides. Fluffy rice or quinoa absorb the flavorful juices from the peppers and fish, making every bite satisfying. Roasted baby potatoes or a simple green salad bring balanced textures and complete the meal, making it perfect for a weekday dinner or when entertaining guests.
Creative Ways to Present
For a fun twist, serve the fish and peppers over a bed of herbed couscous or alongside creamy mashed cauliflower for a low-carb option. Plating the fish and peppers family-style in the baking dish allows everyone to dig in and share, fostering a warm, communal vibe. Pairing the dish with a crisp white wine enhances the Mediterranean experience beautifully.
Make Ahead and Storage
Storing Leftovers
Store any leftover Herb Baked Fish with Rainbow Bell Peppers Recipe in an airtight container in the refrigerator for up to 2 days. The flavors remain vibrant, making it easy to enjoy quick, healthy lunches or dinners later in the week.
Freezing
While fresh is always best with fish, you can freeze cooked leftovers wrapped tightly in plastic wrap and foil or in freezer-safe containers for up to 1 month. Thaw overnight in the refrigerator before reheating to maintain texture and flavor.
Reheating
To reheat, warm your leftovers gently in the oven at 325°F (160°C) for about 10 minutes or until heated through. Avoid microwaving if possible, as it can make the fish rubbery; slow, even heat preserves the tenderness beautifully.
FAQs
Can I use other types of fish for this recipe?
Absolutely! While cod or tilapia are ideal for their mild flavor and flaky texture, you can use any firm white fish like haddock, halibut, or sea bass. Just adjust baking time based on thickness to avoid overcooking.

Yes! All the ingredients in the Herb Baked Fish with Rainbow Bell Peppers Recipe are naturally gluten-free, making it safe for anyone with gluten sensitivities or celiac disease.

This recipe is mild and focuses on fresh herbs and lemony brightness rather than heat. If you like a spicy kick, you can add crushed red pepper flakes when tossing the peppers or sprinkle chili powder over the fish before baking.
Can I prepare this dish ahead of time?
You can prep by slicing the peppers and mixing them with herbs and oil up to a day in advance. Keep the fish separate and seasoned just before baking for the best freshness and texture.
What wines pair well with this dish?
Light, crisp whites like Sauvignon Blanc or Pinot Grigio complement the herbal and citrus notes perfectly. For a non-alcoholic option, sparkling water with lemon also refreshes the palate wonderfully.
