Ingredients Notes

The magic of this dish lies in its simple, vibrant ingredients that highlight the natural flavor of the cod. Here’s what you’ll need:

Fresh cod fillets are the star of this recipe. Look for thick, firm fillets that are white and slightly translucent. If you’re using frozen cod, be sure to thaw it completely and pat it dry to prevent excess moisture from watering down the sauce.

Lemon juice and zest bring brightness and acidity that perfectly balance the richness of the butter. Freshly squeezed lemon is best—avoid bottled juice if you can. Zesting the lemon before juicing helps capture its full citrus aroma.

Unsalted butter is what gives the sauce its luxurious texture. It melts into a silky coating over the fish, infusing each bite with rich flavor. If you're cutting back on dairy, you can swap in a plant-based butter alternative with great results.

Garlic and herbs (like parsley, thyme, or dill) elevate the flavor profile and add a savory depth to the dish. Use fresh herbs when possible—they add a burst of color and fragrance that dried versions can’t match.

You’ll also need a baking dish large enough to fit the fillets in a single layer, along with foil or parchment paper for easy cleanup. A microplane for zesting the lemon is also handy.

How To Make This Summer Lemon Butter Baked Cod

Creating this summer-inspired baked cod is as easy as it is delicious. Here's how to bring it all together:

Start by preheating your oven to 400°F (200°C). While the oven heats, lightly grease your baking dish with olive oil or cooking spray to keep the fish from sticking. Pat the cod fillets dry with paper towels and season both sides with salt and pepper.

In a small saucepan or microwave-safe bowl, melt the butter and stir in the lemon juice, zest, minced garlic, and chopped herbs. This fragrant sauce is the heart of the recipe, and it only takes a minute or two to come together.

Place the cod fillets in your prepared baking dish and spoon the lemon butter mixture evenly over each piece. Make sure the sauce pools a bit at the bottom—this helps keep the fish moist as it bakes.

Bake the cod for 12-15 minutes, depending on thickness. You'll know it's done when the fish flakes easily with a fork and is opaque throughout. Try not to overbake; cod cooks quickly and can dry out if left too long in the oven.

Once out of the oven, let the fish rest for a couple of minutes. Spoon any pan juices back over the top, and garnish with fresh parsley and lemon slices for a touch of elegance.

From start to finish, this recipe takes about 25 minutes. It’s the kind of meal that feels like a treat, even on your busiest day.

Storage Options

Leftover baked cod can be stored in an airtight container in the refrigerator for up to 3 days. Be sure to cool it completely before sealing it to prevent condensation from making it soggy.

For longer storage, you can freeze the cod—though it’s best fresh. Wrap individual portions tightly in plastic wrap, then store in a freezer-safe bag or container for up to 2 months. Thaw overnight in the fridge before reheating.

When reheating, use a low oven (around 300°F) and cover the fish with foil to retain moisture. Avoid the microwave if possible, as it can make the cod rubbery.

If you do microwave, place the fish in a covered container with a splash of lemon juice or broth to help keep it tender.

Variations and Substitutions

One of the best things about this recipe is how adaptable it is. You can easily tweak it based on what you have on hand or your dietary preferences.

Not a fan of cod? Swap it with haddock, halibut, or tilapia. These white fish have a similar texture and bake beautifully in the lemon butter sauce.

Add a kick by sprinkling a pinch of red pepper flakes or a dash of Cajun seasoning into the butter mixture. It’s a great way to introduce a bit of heat without overpowering the dish.

For a dairy-free version, use vegan butter and make sure to check the ingredients for any hidden milk solids. The flavor will still be rich and satisfying.

Make it Mediterranean by tossing in a handful of cherry tomatoes, sliced olives, or capers before baking. These ingredients add complexity and a touch of briny brightness.

Feel free to experiment with the herbs—basil, oregano, or tarragon can all work well. Each gives the dish a slightly different personality while keeping the summer vibe intact.

Don't be afraid to make this recipe your own. Once you've tried the base version, you'll find countless ways to tweak and customize it to suit your taste and pantry.
