Introduction

This Italian baked sea bass is a flavorful and simple dish that brings together roasted peppers, olives, and fresh lemon to complement tender, flaky fish. It’s perfect for a healthy weeknight dinner or a special weekend meal.

The image shows a white rectangular baking dish filled with two whole cooked fish placed side by side on top of a colorful bed of vegetables. The fish are silver-gray with a slight shine, sprinkled with coarse salt and chopped green herbs. Beneath the fish, there is a mix of sliced red onions, lemon slices, red bell pepper pieces, and pine nuts scattered evenly throughout the dish.

Ingredients

About 290g jar whole roasted peppers, drained and sliced
1 red onion, sliced into very thin wedges
Drizzle of olive oil
4 garlic cloves, unpeeled
3 fat slices lemon, plus extra wedges to serve
2 sea bass
15 Kalamata or black olives
25g toasted pine nuts
Handful roughly chopped parsley

Instructions

Step 1: Preheat your oven to 200°C (180°C fan) or gas mark 6. Toss the sliced roasted peppers and red onion wedges with seasoning and a small drizzle of olive oil. Spread them evenly on a baking tray and roast for 5 minutes.
Step 2: Add the unpeeled garlic cloves and lemon slices to the tray, nestling them among the peppers and onions. Place the sea bass on top of the vegetables, brush the fish with a little more olive oil, and season it well. Roast everything together for 15 minutes.
Step 3: Stir the Kalamata or black olives and toasted pine nuts into the vegetables on the tray. Return to the oven and roast for an additional 5 minutes, or until the fish is cooked through and flakes easily with a fork.
Step 4: Remove from the oven, squeeze some fresh lemon juice over the fish and vegetables, and sprinkle with the chopped parsley before serving.

Tips & Variations

For extra flavor, add a splash of white wine before roasting the fish.
You can substitute sea bass with other firm white fish like cod or snapper.
To make it spicier, add a pinch of chili flakes when tossing the peppers and onions.
Use fresh roasted peppers if available for an even better taste.

Storage

Store any leftover baked sea bass in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven at a low temperature to keep the fish tender, or enjoy it cold in a salad the next day.
