These lemon butter cod fillets bake in a bright, buttery sauce of fresh lemon juice, zest, garlic, and parsley until they flake apart with a fork.
They need about ten minutes of prep and fifteen in the oven. The butter keeps the lean fish moist and carries the lemon through every bite.

Why This Lemon Butter Cod Fillets Recipe Works
Cod is lean and mild, so it benefits from a rich coating. Melted butter bastes the fillets as they bake and protects them from drying out.
Lemon juice and zest add real citrus flavor, while garlic powder blends evenly into the butter without burning. Parsley adds color and a fresh, green taste.
Brushing half of the sauce on before baking and pouring the rest over the top gives the fish two layers of flavor, and the pan juices become a ready made sauce for serving.
Ingredients for Lemon Butter Cod Fillets
- Fish: four skin on cod fillets, with salt and black pepper.
- Sauce: one half cup of softened unsalted butter, the juice and zest of two lemons, one teaspoon of garlic powder, and one tablespoon of chopped parsley.
Cod fillets. Thick, fresh fillets bake evenly. Pat them dry first.
Butter. Bastes the fish and makes the sauce rich.
Lemon juice and zest. Provide bright flavor and fragrance.
Garlic powder. Blends into the butter without burning.
Parsley. Adds a fresh herb finish.
How to Make Lemon Butter Cod Fillets
1. Heat the oven. Heat the oven to 400 degrees F and line a baking sheet with parchment paper.
2. Dry and season. Pat the cod dry with paper towels and season both sides lightly with salt and pepper.
3. Make the sauce. Mix the butter with the lemon juice, lemon zest, garlic powder, and parsley.
4. Brush. Brush half of the sauce over the fillets and place them on the sheet.
5. Bake. Pour the remaining sauce over the top and bake for twelve to fifteen minutes.
6. Rest and serve. Make sure the fish reaches 145 F and flakes easily, then rest it for three minutes.
How to Serve Lemon Butter Cod Fillets
Serve the cod with the pan sauce and fresh lemon wedges. It pairs well with parmesan roasted green beans and garlic onion seasoned rice, and honey butter dinner rolls add a soft bread for the sauce. For another white fish dinner, try grilled halibut later in the week.
How to Store and Reheat Lemon Butter Cod Fillets
Cool the cod within two hours and store it in an airtight container in the refrigerator for up to two days. Reheat gently in a low oven or covered skillet until warm, since lean fish dries out fast with high heat. The butter may firm up in the refrigerator, so spoon the sauce over the fish while warming. Flake leftovers into rice, pasta, or tacos for another meal. Do not freeze the cooked fish because it turns watery, though raw fillets freeze well for two months. For a creamy sauce to serve at the table, spoon the buttery juices from the pan into a small bowl and stir in a pinch of salt and a little extra lemon juice. Drizzle it over rice or vegetables so nothing goes to waste. Leftover fish also makes a good filling for sandwiches with lettuce, a little mustard, and thin slices of cucumber.
Tips and Variations for Lemon Butter Cod Fillets
Flag the allergens. This dish contains fish and milk. Check the garlic powder and parsley labels for other allergens.
Cook the fish safely. Cod is done at 145 F and flakes easily. Do not serve fish that is translucent in the center.
Season smartly. Add the salt in small amounts, then adjust the salt to taste once everything is combined.
Soften the butter. Soft butter blends smoothly with lemon and spreads evenly.
Zest before juicing. It is easier to zest a whole lemon than a juiced half.
Use parchment. It keeps the butter from sticking and makes cleanup simple.
Try a swap. Use olive oil instead of butter for a lighter version, or add dill for a fresh finish.
Check trusted guidance. For food safety basics, including safe handling and storage, read the FDA safe food handling guidance.
