Ingredients

• White fish fillets (cod, hake, pollock) — 600g (1 lb 5 oz)
• Cherry tomatoes — 200g (7 oz)
• Medium zucchini — 1
• Red bell pepper — 1
• Red onion — 1/2
• Olive oil — 2 tbsp
• Unsalted butter — 30g (2 tbsp)
• Capers — 2 tbsp
• 1 lemon (zest and juice) — 1
• Garlic — 2 cloves
• Dry white wine (optional) — 50ml (3 1/3 tbsp)
• Fresh parsley, chopped — 2 tbsp
• Salt — 1 tsp, or to taste
• Freshly ground black pepper — 1/2 tsp

Step-by-Step Recipe

1. Prep the ingredients: pat the fish dry with paper towels, season with salt and pepper, zest the lemon, and slice the vegetables — zucchini into half-moons, pepper into strips, onion into wedges, and cherry tomatoes in half.
2. Heat a skillet over medium heat with 1 tbsp olive oil and sauté the vegetables for 5–6 minutes, until tender and lightly browned. Transfer to a plate.
3. In the same skillet, add the remaining olive oil and sear the fish fillets for 2–3 minutes per side, until golden and cooked through. Transfer to the vegetables, keeping the pan juices.
4. Reduce the heat to medium, melt the butter in the skillet, add the minced garlic, and cook for 30 seconds until fragrant. Pour in the white wine, if using, and the lemon juice, bring to a boil, and reduce for 1–2 minutes.
5. Stir in the capers, lemon zest, and parsley. Return the fish and vegetables to the skillet, spoon the sauce over everything, and warm through for 1 minute.
6. Serve at once, finished with extra parsley and lemon wedges.

Tips and Variations

• Fish: firm white fish works best — cod, hake, pollock, or sea bass. The fillets should be cold and very well dried.
• No wine: replace it with the same amount of stock or water plus a pinch of salt and a few drops of vinegar.
• Crisp crust: don’t move the fillets for the first 2 minutes — the fish will release naturally and the crust will brown evenly.
• Seasonal vegetables: add asparagus, green beans, broccoli, or thin fennel slices.
• More sauce: increase the butter to 40g (3 tbsp) and add 1–2 tbsp water or stock at the end.

What to Serve It With

• Mashed potatoes, basmati rice, or couscous
• Crisp baguette for the sauce
• A simple green salad with olive oil and lemon

Storage and Reheating

• Store in the refrigerator for up to 24 hours in an airtight container.
• Reheat gently over low heat, covered, for 2–3 minutes with 1–2 tbsp water to keep the fish from drying out.
• Freezing is not recommended — the texture of the fish and vegetables will suffer.

Frequently Asked Questions

• Can I make this in the oven? Yes. Bake the fish and vegetables at 400°F (200°C) for 12–15 minutes, make the sauce on the stove, and spoon it over just before serving.
• What can I use instead of capers? Chopped green olives or finely chopped cornichons; add a little lemon juice for brightness.
• How do I know when the fish is done? The flesh turns opaque and flakes easily with a fork; the internal temperature should be about 125–131°F (52–55°C).
• Can I use frozen fillets? Yes, fully thaw them on a refrigerator shelf and pat them very dry before cooking.
• How can I make this dish lighter? Reduce the butter to 15–20g (1–1 1/2 tbsp) and increase the amount of vegetables.
