Baked Cod with Lemon and Chive Butter

wafaawjjamal

• Prep time: 5 minutes
• Cook time: 15 minutes
• Total time: 20 minutes

• Serves: 4

Ingredients

For the cod:

• 4 cod fillets, about 5 to 6 ounces each
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon garlic powder
• 1/4 teaspoon paprika

For the lemon and chive butter:

• 4 tablespoons unsalted butter, softened
• 2 tablespoons fresh chives, finely chopped
• 2 cloves garlic, finely grated or minced
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper

For serving:

• Lemon slices
• Extra chives, for garnish
• Lemon wedges

Instructions

• 1)

  Make sure to carefully follow each step of the instructions for the best results :

  • Preheat the oven.
    Set the oven to 400°F and lightly grease a baking dish large enough to hold all four fillets in a single layer. Most lemon butter baked cod recipes use a 400°F oven, which gives the fish a clean, even bake without drying it out.
  • Make the lemon chive butter.
    In a small bowl, mix together the softened butter, chives, garlic, lemon juice, lemon zest, salt, and pepper until smooth and well combined. This compound-style butter can be made ahead and kept in the fridge if you want to save even more time on a weeknight.
  • Prep the cod.
    Pat the cod fillets very dry with paper towels, then place them in the prepared baking dish. Season both sides with salt, pepper, garlic powder, and paprika. Patting the fish dry before baking helps it cook more evenly and gives the butter a better surface to cling to.
  • Add the butter and lemon.
    Spread the lemon chive butter evenly over the top of each fillet, dividing it equally. Lay a slice of lemon on top of each piece and pour any remaining butter around the fillets in the dish. Spooning or spreading the butter mixture directly over the cod before baking is a consistent technique in most lemon butter cod recipes for a flavorful, glossy finish.
  • Bake until flaky.
    Bake for 12 to 15 minutes, depending on the thickness of the fillets, until the cod is opaque and flakes easily with a fork. The safe internal temperature for cod is 145°F, and the fish should look moist and tender rather than dry.
  • Garnish and serve.
    Spoon the buttery pan juices over each fillet before serving, then scatter extra chives on top and add lemon wedges on the side. Serve immediately while the butter sauce is warm and glossy.

Tips for the Best Baked Cod with Lemon and Chive Butter

• Pat the cod completely dry before baking so the butter sticks properly
• Use softened butter so it spreads easily and blends smoothly with the herbs
• Fresh chives give the most vibrant, mild onion flavor; dried chives also work in smaller amounts
• Don’t overbake the cod or it can become dry and fall apart too easily
• Thicker fillets need a few extra minutes while thinner ones may be done closer to 12 minutes
• Baste the fillets with the pan butter before serving for the most flavorful result
• A squeeze of fresh lemon right before eating brightens every bite

Variations

• Garlic herb version. Add dill, thyme, or parsley to the butter alongside the chives for a more complex herb finish
• Parmesan crust version. Sprinkle a little grated Parmesan over the butter topping before baking for a lightly golden, savory crust
• Spicy version. Add a pinch of red pepper flakes or a small amount of Dijon mustard to the butter for extra depth
• Cherry tomato version. Add halved cherry tomatoes to the baking dish for a bright, slightly saucy finish
• Dairy-free version. Replace the butter with a good quality dairy-free butter alternative for a similar result

Can I Use Frozen Cod Instead of Fresh?

Yes, and it works very well in this recipe. Thaw the fillets fully first, then pat them very dry with paper towels before adding the butter. Excess moisture from frozen fish can cause the butter to slide off, so drying them well is the most important step.

What to Serve with Baked Cod with Lemon and Chive Butter

This light low carb dinner pairs beautifully with clean, simple sides:

• Roasted asparagus
• Sautéed garlic spinach
• Cauliflower rice
• Steamed green beans
• Roasted zucchini
• A crisp green salad with lemon vinaigrette

Storage & Reheating

Store leftover cod in an airtight container in the refrigerator for up to 2 days. Fish is always best fresh, but this recipe holds up reasonably well for a next-day lunch.

To reheat, warm gently in a 275°F oven for about 8 to 10 minutes, or microwave at reduced power in short intervals until just warm. Avoid high heat, which can dry out the cod quickly and make it lose its flaky texture.

FAQ

How do I know when cod is fully cooked?

The cod should turn completely opaque and flake easily with a fork. The internal temperature should reach 145°F at the thickest part.

Can I make the lemon chive butter ahead of time?

Yes. Mix the butter and refrigerate it for up to 3 days. Let it soften slightly before spreading over the fish.

Is this recipe gluten-free?

Yes, it is naturally gluten-free as written.

Can I use another white fish instead of cod?

Yes. Haddock, halibut, tilapia, and sea bass all work well with the same lemon chive butter and baking method.

Can I add vegetables to the baking dish?

Yes. Asparagus, cherry tomatoes, and zucchini all roast well alongside the cod in the same dish.
