Simple Ingredients for Big Flavor

• 4 cod fillets (6 oz each, about 1-inch thick), fresh or thawed from frozen
• 4 tbsp unsalted butter, melted
• 3 cloves garlic, minced
• 1 tsp lemon zest
• 2 tbsp fresh lemon juice
• 1/2 tsp salt, or to taste
• 1/4 tsp black pepper, freshly ground
• 2 tbsp fresh parsley, chopped (for garnish)

How to Bake Perfect Cod

1. Preheat the oven to 400°F (200°C).
2. If using frozen cod, thaw completely before proceeding.
3. Pat cod fillets completely dry with paper towels.

4. Season both sides of the fillets with salt and freshly ground black pepper.

   

5. Arrange the fillets in a single layer in a baking dish (9×13-inch or similar).
6. Melt the butter and in a small bowl whisk together the melted butter, minced garlic, lemon zest, and fresh lemon juice until combined.
7. Pour the lemon-garlic-butter sauce evenly over the cod, coating each fillet.

8. Bake uncovered for 12–15 minutes (start checking at 12) until the fish is opaque and flakes easily with a fork or reaches 145°F internal temperature.

9. Remove from the oven and sprinkle with chopped fresh parsley.

   

Chef Tips for Perfect Texture

I’ve learned a few tricks to make sure your baked cod comes out perfectly every time. Here’s what I recommend:

• Watch the clock: Overcooking is the number one cause of dry fish. Start checking at 12 minutes. The fish will keep cooking a bit after you take it out of the oven thanks to residual heat.
• Dry it off: Make sure you pat your fillets completely dry before seasoning and baking. That prevents steaming and helps the fish bake nicely.
• Choose thicker cuts: Fillets about 1 inch thick work best because they stay moist and cook evenly without drying out.

• Serve with roasted vegetables like asparagus, broccoli, or carrots for a colorful plate.
• Pair with fluffy quinoa, rice, or light mashed potatoes for a filling, balanced meal.
• A crisp green salad dressed with a lemon vinaigrette complements the fish’s bright flavors perfectly.
• Fresh lemon wedges on the side add a nice zesty finish.

Ways to Customize the Dish

This baked cod recipe is a fantastic starting point, and you can make it your own with a few easy tweaks.

• Herb boost: Stir in fresh herbs like dill, thyme, or oregano into the butter sauce for some extra fresh flavor.
• Bring on the heat: Add a pinch of red pepper flakes to the sauce for a gentle kick of spice.
• Cheesy finish: Sprinkle some freshly grated Parmesan over the fillets in the last 5 minutes of baking. It creates a deliciously golden, cheesy crust—kind of like a simple garlic Parmesan shrimp twist.

Look at that perfectly flaky texture!

This recipe partners well with so many sides. For a full, healthy dinner, try serving it alongside roasted asparagus or broccoli, fluffy quinoa, or comforting mashed potatoes. A crisp, simple salad also makes a fresh, light side.

• Add a sprinkle of red pepper flakes to the sauce for a subtle heat.
• Finish with a sprinkle of grated Parmesan cheese during the last few minutes of baking for a golden, cheesy crust.
• Swap out parsley for fresh dill or thyme for a different herbal note.
• Use other flaky white fish like haddock, halibut, or pollock if cod isn’t available.

Storing and Reheating Leftovers

Got leftovers? Store your baked cod in an airtight container in the fridge for up to two days. To warm it back up, low and slow is the way to go—heat in the oven at about 275°F until just warmed through to keep the fish tender and not dried out. Or, cool flakes of leftover cod are great tossed into salads, folded into fish cakes, or mixed into a quick sandwich for lunch.

If you happen to have leftovers, store them in an airtight container inside the fridge. They’ll keep for up to 2 days, making a quick lunch or dinner lifesaver. Just be sure to reheat gently so the fish doesn’t dry out.

You can prep the lemon garlic butter sauce up to a day in advance and keep it covered in the fridge. When you’re ready to cook, just pour it over the seasoned cod and bake as usual. This little shortcut saves you time on busy nights without sacrificing flavor.
