You’ve stared into your fridge on a Saturday night wondering how to make something good from whatever’s there? Two cod fillets, a pot of cream, a lemon lurking in the corner—that’s exactly the situation this recipe is made for. Simple, quick, and with real flair on the plate.

Ingredients :
- Cod (4 fillets) — It’s a fish with delicate, slightly sweet flesh that cooks quickly and can’t handle too aggressive heat for too long. Choose thick, uniform fillets—thin tails will cook before the center is ready. Fresh is ideal, but properly thawed cod from the refrigerator the day before works great. Avoid leaving it at room temperature too long before baking: it cooks more evenly when still cold.
- Mustard (2 tbsp) — It has a dual role here: giving character to the sauce, and also helping it hold together and coat the fish properly. Dijon for something smooth and sharp, whole-grain for more texture and a milder, grainier taste. Taste the sauce before baking—if it seems too strong cold, know that it will mellow slightly during cooking.
- Heavy cream (7 fl oz / 200 ml) — This envelops the fish during cooking and prevents it from drying out. Choose full-fat cream with at least 30% fat: it withstands heat without separating into small grains. Light cream tends to curdle in the oven, especially with lemon. For a lighter version that stays stable, full-fat fromage blanc is a valid alternative.
- Lemon (juice of ½ to 1 whole) — Lemon cuts through the richness of the cream and provides the brightness that makes the dish feel light despite the sauce. Start with the juice of half a lemon, taste, and adjust. A whole lemon can easily dominate if your fruit is particularly tart. If you have time, add some zest to the sauce—a more aromatic and less aggressive note than juice alone.
