- Garlic cloves (4, minced): Infuses every bite with a warm, aromatic depth that pairs beautifully with lemon.
- Salt and pepper (to taste): Essential for seasoning and bringing out the natural flavors in the fish and sauce.
- Butter (¼ cup, diced): Melts into rich pockets across the fish, creating a silky texture and indulgent flavor.

How to Make Garlic Butter Lemon Baked Cod Recipe
Step 1: Prep Your Oven and Baking Dish
Start by preheating your oven to 400 degrees Fahrenheit. Lightly grease a rectangular baking dish that will comfortably fit your cod fillets. This step ensures easy cleanup afterward and helps prevent the fish from sticking during baking. Place the seasoned cod gently inside the dish, ready to be bathed in all that buttery lemon goodness.
Step 2: Whisk Together the Zesty Sauce
In a small bowl, combine the olive oil, freshly squeezed lemon juice, and minced garlic. Season this mixture with salt and pepper to your preference. Give it a good whisk. This simple sauce packs an incredible punch of flavor that mingles perfectly with the cod as it bakes, keeping it juicy and tender.
Step 3: Assemble the Dish for Baking
Pour your bright lemon garlic sauce evenly over the cod fillets in the baking dish. Scatter the diced butter pieces over the top, allowing them to melt slowly during baking, creating a luscious coating. Finally, arrange thin lemon slices on each fillet—not only does this infuse flavor, but it also adds a lovely, inviting look.
Step 4: Bake Until Flaky Perfection
Place the dish in the preheated oven and bake for 15 to 20 minutes. You’ll know the cod is done when it turns opaque and flakes easily with a fork. Keep an eye on it—the beauty of this recipe is in its simplicity, but timing is key to avoid overcooking. Once out of the oven, if desired, sprinkle chopped parsley to add that final burst of color and freshness.
How to Serve Garlic Butter Lemon Baked Cod Recipe

Garnishes
Adding chopped fresh parsley is a fantastic way to finish the dish, bringing a pop of green and a subtle herbaceous note that complements the rich garlic butter sauce. A few extra lemon wedges on the side invite guests to add an extra splash of brightness if they wish.
Side Dishes
This Garlic Butter Lemon Baked Cod Recipe pairs wonderfully with light and fresh sides. Think fluffy steamed rice to soak up the buttery sauce, roasted vegetables like asparagus or broccoli for crunch and earthiness, or even a crisp green salad with a lemon vinaigrette to echo the citrus notes of the main dish.
Creative Ways to Present
For a special touch, serve the cod on a bed of couscous or creamy mashed potatoes to soak up the flavorful juices. You can also plate it family-style, letting everyone help themselves, which encourages sharing and enjoying the moment together. Garnishing with edible flowers or microgreens adds an elegant flair that’s sure to wow at any dinner table.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the cod in an airtight container in the refrigerator. The rich garlic butter sauce helps maintain flavor and moisture, keeping it enjoyable for up to two days. Just be sure to cool it completely before refrigerating to preserve freshness.
Freezing
While fresh is always best for this dish, you can freeze cooked cod wrapped tightly in plastic wrap followed by foil or in a freezer-safe container. It’s best eaten within one month for optimal taste and texture. Thaw it overnight in the refrigerator before reheating gently.
Reheating
To reheat, place the cod in a low oven (around 275°F) for about 10–15 minutes to warm through without drying out the delicate fish. Alternatively, a gentle steam or microwave on low power can work, but take care not to overcook, as cod is naturally lean and can quickly become tough.
FAQs
Can I use frozen cod fillets for this recipe?
Absolutely! Just be sure to thaw them completely and pat them dry before seasoning and baking. This helps prevent excess moisture and ensures the sauce clings beautifully to the fish.
What can I substitute for fresh lemon juice?
If fresh lemons aren’t on hand, bottled lemon juice will do in a pinch, but fresh is always best for brightness and flavor purity in this Garlic Butter Lemon Baked Cod Recipe.
Is it possible to make this recipe dairy-free?
Yes, you can swap the butter for a plant-based alternative or extra olive oil. Keep in mind the flavor profile will be a bit different but still delicious and full of garlic and lemon zest.
How do I know when the cod is perfectly cooked?
The key signs are that the fish turns opaque, flakes easily when tested with a fork, and has an internal temperature of about 145°F if using a thermometer.
Can I prepare the sauce ahead of time?
Definitely! The lemon garlic sauce can be whisked together a few hours in advance and kept covered in the fridge. Just be sure to add the butter right before baking for that perfect melting effect.

From start to finish, this Garlic Butter Lemon Baked Cod Recipe delivers a mouthwatering seafood dinner with minimal effort and maximum flavor.
