Instructions

  1. Step 1: Preheat oven to 375°F. Lightly oil a baking dish with 1 tbsp olive oil and place 4 cod fillets seasoned with 1 tsp salt and 1/2 tsp black pepper spaced evenly.

  3. Step 3: Meanwhile, melt 4 tbsp unsalted butter in a small saucepan over medium heat. Stir in 2 tbsp lemon juice and 2 tbsp drained capers, cooking for 2 minutes until sauce is fragrant and slightly thickened.
  4. Step 4: Remove cod from oven, spoon lemon-caper butter sauce generously over each fillet, and sprinkle 1 tbsp chopped fresh parsley on top before serving.

Frequently asked questions

How long does Baked Cod with Lemon-Caper Butter Sauce take to make?

Total time is about 20 minutes (5 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Baked Cod with Lemon-Caper Butter Sauce?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Baked Cod with Lemon-Caper Butter Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Baked Cod with Lemon-Caper Butter Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
