Cod in Tomato Sauce with Garlic and Capers

Cod in tomato sauce cooks gently in a single skillet without flouring or frying the fish first. Onion softens into the sauce, while capers and lemon add a clear tang. Let the tomato base simmer before adding the fillets so their shorter cooking time does not rush the sauce. Cod breaks easily when fully cooked; spoon sauce around it instead of repeatedly turning the pieces. Serve with something plain that can absorb the broth-like sauce.

Helpful tips

• Check the fish for remaining pin bones.
• Simmer the sauce before adding cod.
• Keep bubbling gentle once fish enters the pan.
• Lift cooked portions with a broad utensil.

Troubleshooting

• Thaw in the refrigerator first for this timing. Frozen fillets release extra water and change the cooking duration.
• Lift cooked portions with a broad utensil.

Serving ideas

• Spoon over plain rice.
• Serve with boiled potatoes.
• Offer crusty bread for the sauce.
• Add steamed green beans alongside.

Substitutions

Haddock or hake can replace cod if similarly thick. Omit capers if unavailable and adjust seasoning after tasting.

Variation

Add 1/4 teaspoon chilli flakes with the garlic.

Make ahead

Make the tomato sauce a day ahead and refrigerate. Bring it to a simmer before adding fresh fish on the serving day.

Storage and reheating

Refrigerate promptly for up to 3 days. Reheat fish and sauce to 74°C (165°F), handling gently to avoid breaking the flakes.

Food safety

Use clean utensils and wash produce. Keep perishable ingredients refrigerated at 4°C (40°F) or below. Refrigerate perishable leftovers promptly, within 2 hours, or within 1 hour above 32°C (90°F).
