Step‑by‑Step Instructions for Lemon Butter Baked Cod
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Lemon Butter Baked Cod cooks evenly and develops that lovely flaky texture. While the oven warms up, gather your ingredients and prepare your baking dish, making it ready for the succulent cod fillets.
Step 2: Prepare the Baking Dish
Lightly grease a baking dish with a bit of olive oil or butter. This not only prevents the fish from sticking but also adds a hint of flavor. Make sure the dish is big enough to accommodate all the cod fillets in a single layer for even baking, which is vital for your Lemon Butter Baked Cod.
Step 3: Season the Cod
Take your cod fillets out of the refrigerator and let them come to room temperature, about 10 minutes. Pat them dry with paper towels to absorb any excess moisture, ensuring a better sear. Season both sides generously with salt and pepper, enhancing the overall flavor of your Lemon Butter Baked Cod.
Step 4: Make the Lemon Butter Sauce
In a small mixing bowl, combine melted unsalted butter with freshly squeezed lemon juice, minced garlic, lemon zest, and dried thyme. Whisk this mixture thoroughly until it’s smooth and well combined. This zesty sauce will infuse your Lemon Butter Baked Cod with rich flavors that are sure to delight.
Step 5: Arrange the Cod
Place the seasoned cod fillets in your prepared baking dish. Drizzle the lemon butter sauce evenly over the fish, ensuring each piece is generously coated. The lovely combination of butter, lemon, and herbs will seep into the cod, enhancing its natural flavors as it bakes to perfection.
Step 6: Bake to Perfection
Slide the baking dish into the preheated oven and bake the cod for 15-20 minutes. Keep an eye on the fillets; they’re done when the fish flakes easily with a fork and reaches an internal temperature of 145°F (63°C). This is key to achieving that tender and flaky Lemon Butter Baked Cod.
Step 7: Let it Rest
Once your Lemon Butter Baked Cod is out of the oven, allow it to rest for a few minutes. This brief pause lets the flavors settle and enhances the dish's overall taste and texture. If desired, you can garnish it with fresh parsley for a burst of color and freshness before serving.

Expert Tips for Lemon Butter Baked Cod
- Even Thickness: Ensure your cod fillets are of uniform thickness to promote even cooking throughout your Lemon Butter Baked Cod. Thin edges can overcook while thicker pieces remain raw.
- Pat Dry: Pat the fillets dry with paper towels before seasoning. This prevents excess moisture, resulting in a flavorful, crispy crust rather than a watery dish.
- Early Check: Always check the doneness of your fish a few minutes early. Fish should easily flake with a fork and reach 145°F inside to avoid overcooking your Lemon Butter Baked Cod.
- Butter Emulsion: Whisk your lemon butter sauce thoroughly to ensure it emulsifies well. A well-emulsified sauce prevents separation during baking, keeping flavors intact.
- Room Temperature: Allow cod fillets to come to room temperature before cooking. This helps with more even cooking and ensures that beautiful flaky texture is achieved.
Make Ahead Options
Preparing your Lemon Butter Baked Cod in advance not only saves time but also allows the flavors to meld beautifully, creating a dish that’s just as delicious. You can season the cod fillets and make the lemon butter sauce up to 24 hours before cooking. Simply store the seasoned cod in an airtight container in the refrigerator, and keep the sauce in a separate container to prevent any moisture from compromising its quality. When you're ready to bake, pour the lemon butter sauce over the prepared fillets and bake as directed. This approach ensures a quick and satisfying meal with minimal effort on busy weeknights!
