These ingredients are straightforward and easy to find, yet each plays a crucial role in making this dish pop with flavor and pleasing texture. From the richness of butter to the fresh zing of lemon, every element works in harmony to highlight the delicate cod fillets.

  • 8 4-oz Cod fillets: Choose firm, fresh or thawed cod for perfect flaky texture.
  • ¼ cup Unsalted butter: Melts smoothly to coat the fish and add a rich, velvety base.
  • 1 medium Lemon (juiced and zested): Adds bright acidity that cuts through the butter for balance.
  • ½ teaspoon Garlic powder: Imparts a subtle, savory depth without overpowering the cod.
  • ¾ teaspoon Sea salt: Enhances all the natural flavors beautifully.
  • ¼ teaspoon Black pepper: Offers a gentle heat and aromatic spice.
  • 1 tablespoon Fresh parsley (chopped): Sprinkled at the end for color and a fresh herbal lift.

How to Make Baked Lemon Butter Cod Recipe

Step 1: Preheat and Prepare Your Cod

Start by preheating your oven to 400 degrees Fahrenheit (or 204 Celsius). If you have time, thaw your cod fillets in a bowl of cold water for easier handling and better absorption of the lemon butter. Pat the fillets dry with paper towels—this step is key for a nice finish—and arrange them in a single layer in your baking dish.

Step 2: Create the Lemon Butter Mixture

Next, melt the butter either in the microwave or on the stovetop. Once melted, stir in your freshly squeezed lemon juice and fragrant lemon zest. This mixture is the magic that brings brightness and richness together perfectly for your cod.

Step 3: Butter and Season Every Side

Using a pastry brush or spoon, generously coat each cod fillet with the lemon butter. Then sprinkle garlic powder, sea salt, and black pepper evenly over the fillets. Flip them carefully and repeat the buttering and seasoning on the other side. This ensures every bite is flavorful and moist.

Step 4: Bake to Flaky Perfection

Place the baking dish in the oven and bake for 12 to 15 minutes. The exact time will vary depending on the thickness of your fillets, but your goal is for the fish to turn opaque and flake easily with a fork. If you want to be precise, aim for an internal temperature between 135-140 degrees Fahrenheit for the perfect tender texture.

Step 5: Garnish and Serve

When your cod is out of the oven and smelling divine, sprinkle the chopped fresh parsley on top. This final touch not only adds a lovely pop of color but also a fresh flavor contrast that brightens the entire dish.

The fish is covered with small green parsley flakes and cracked black pepper. Between the fish pieces are thin, bright yellow lemon slices with visible watery pulp. The dish has a gentle coating of light yellow lemon butter sauce pooling around the fish. Small sprigs of fresh green parsley lie around the fish and lemon slices, all set on a white marbled surface.

Garnishes

Fresh parsley is my personal favorite for garnish, but you can also add thin lemon slices or a sprinkle of finely minced chives for extra elegance. These simple touches boost the visual appeal and add layers of fresh flavor that complement the buttery cod beautifully.

Side Dishes

This lemon butter cod pairs wonderfully with roasted vegetables like asparagus or Brussels sprouts, steamed green beans, or a light salad with a citrus vinaigrette. For something heartier, creamy mashed potatoes or fluffy rice soak up the buttery sauce perfectly, rounding out the meal.

Creative Ways to Present

For a special touch, serve the cod on a bed of herbed quinoa or wild rice, with some lemon wedges on the side for guests to squeeze fresh juice over their portions. You can also plate it atop warm polenta or alongside a colorful couscous salad to make the presentation pop and delight your diners visually and palate-wise.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which is rare because this recipe is so good!), transfer them to an airtight container and store in the fridge. They’ll keep well for up to two days, making a perfect next-day lunch or quick dinner option.

Freezing

Freezing cooked cod is possible but not ideal due to the delicate texture. If you must, wrap the fillets tightly in plastic wrap and foil, then freeze for up to one month. Thaw slowly in the fridge before reheating gently to prevent drying out.

Reheating

To reheat, do so gently in a low-temperature oven or microwave on a reduced power setting to avoid overcooking the fish. Adding a little extra lemon butter or olive oil before reheating helps maintain moistness and fresh flavor.

FAQs

Can I use other types of fish for this recipe?

Absolutely! While cod is ideal for its mild flavor and flaky texture, you can use other white fish like haddock, halibut, or pollock with similar results. Just adjust baking time based on thickness.

Do I need to thaw the cod before baking?

Thawing cod first is recommended if you have the time because it helps the lemon butter and seasonings adhere better and ensures even cooking. However, you can bake it directly from frozen; just add a few extra minutes to the baking time.

Is it possible to make this recipe dairy-free?

Yes, swap the unsalted butter with a dairy-free alternative like margarine or olive oil. The key is to keep the richness while maintaining that lovely lemon flavor.

How can I tell when the cod is perfectly cooked?

The fish should be opaque all the way through and flake easily with a fork. If you want to be precise, use a meat thermometer to check for an internal temperature between 135-140 degrees Fahrenheit.

Can I prepare the lemon butter ahead of time?

You can mix the melted butter with lemon juice and zest in advance and refrigerate it, but bring it back to room temperature or gently rewarm before brushing on the fish to ensure smooth application.

Final Thoughts

This Baked Lemon Butter Cod Recipe is a delightful way to enjoy fresh seafood with minimal effort but maximum flavor. The gorgeous combination of tender cod, buttery lemon sauce, and simple seasonings comes together beautifully and offers a meal that feels special yet approachable. Give it a try and watch it become a beloved staple in your kitchen and on your family’s dinner table—trust me, you’ll be glad you did!

Description

This Baked Cod Recipe is a quick and flavorful seafood dish that takes just 20 minutes to prepare and cook. Cod fillets are coated with a zesty lemon butter sauce seasoned with garlic powder, sea salt, and black pepper, then baked to tender, flaky perfection. Garnished with fresh parsley, it’s a light, healthy option perfect for weeknight dinners or entertaining guests.


Ingredients

Fish

  • 8 fillets of cod, 4 ounces each (preferably thawed)

Sauce

  • ¼ cup unsalted butter
  • 1 medium lemon, juiced and zested

Seasoning

  • ½ teaspoon garlic powder
  • ¾ teaspoon sea salt
  • ¼ teaspoon black pepper
  • 1 tablespoon fresh parsley, chopped


Instructions

  1. Preheat the Oven: Preheat your oven to 400°F (204°C). You can use cod fillets straight from the freezer or thaw them first in cold water for easier handling and butter application.
  2. Prepare Cod Fillets: Pat the cod fillets dry thoroughly using paper towels to remove excess moisture. Arrange the fillets in a single layer inside a 9x13 inch baking dish.
  3. Make Lemon Butter Sauce: Melt the butter in a microwave or a small saucepan on the stove. Once melted, remove from heat and stir in the freshly squeezed lemon juice and lemon zest to create a bright, flavorful sauce.
  4. Season the Cod: Using a brush, coat each cod fillet evenly with the lemon butter sauce. Sprinkle garlic powder, sea salt, and black pepper over the tops, then carefully flip each fillet and repeat the butter brushing and seasoning on the other side.
  5. Bake the Cod: Place the baking dish in the preheated oven and bake for 12 to 15 minutes, depending on the thickness of the fillets. The cod is done when it turns opaque and flakes easily when tested with a fork. Aim for an internal temperature between 135°F and 140°F for perfectly moist and tender fish.
  6. Garnish and Serve: Remove from oven and sprinkle freshly chopped parsley over the cod fillets. Serve immediately for a delicious, healthy meal.

Notes

  • Thawing the cod fillets beforehand makes it easier to brush the lemon butter sauce evenly without solidifying the butter.
  • Adjust baking time based on fillet thickness to avoid overcooking and drying out the fish.
  • Use fresh lemon juice and zest for the most vibrant flavor.
  • Check the fish with a fork to ensure it flakes easily—this is the best indicator of doneness.

Welcome to Recipes By Lea

I spent most of my twenties working as a freelance travel photographer, bouncing between cities for weeks at a time. Lisbon, Istanbul, Bangkok, Mexico City—wherever a client needed architecture, street life, and local culture captured in a real, honest way. It was exciting and fast, but it also meant inconsistent routines and way too many meals that came from cafés, room service, or whatever I could grab between shoots.
