Cod Fish Recipe Oven: Garlic Butter Baked to Flaky Perfection

This oven-baked cod recipe delivers flaky, tender fish with minimal effort. The secret is precise timing and temperature control.

Garlic butter infuses each bite with rich flavor while the oven ensures perfect, even cooking every time. Simple, foolproof, and ready in under 20 minutes.

Ingredients for Cod Fish Recipe Oven

Fresh cod, bright garlic butter, and a few pantry staples create this foolproof dish.

The cod is the star here. Wild-caught Pacific cod has the best flake and mild flavor, but Atlantic works too. Look for fillets that are ivory-colored and slightly translucent—avoid any with a fishy odor. Most seafood counters at Whole Foods or Trader Joe’s will have it fresh on ice. If you’re using frozen, thaw it overnight in the fridge (not on the counter) to maintain texture.

No white wine? Substitute chicken or vegetable broth for deglazing, though the acidity of wine does brighten the sauce. Fresh garlic is essential here—jarred minced garlic lacks the punch. If you’re out of parsley, fresh dill or chives work beautifully. The butter can be swapped for olive oil for a lighter finish, but you’ll sacrifice some richness.

Baked cod is best served immediately, but leftovers keep for 2-3 days in the fridge. Reheat gently in a 275°F oven to avoid drying out. The garlic butter can be made ahead and stored in the fridge for 1 week—just warm it before using.

Step-by-Step Instructions for Garlic Butter Baked Cod

Here’s the method. Straightforward, tested, works every time.

Step 1: Prep the Cod Fillets and Baking Dish

Preheat your oven to 400°F. Lightly grease a baking dish with the 2 tbsp olive oil, ensuring the bottom and sides are evenly coated. This prevents the cod from sticking and enhances browning.

Pat the 1.5 lb cod fillets dry with paper towels—moisture is the enemy of crispy edges. Arrange them in a single layer in the prepared dish. Season both sides evenly with the 1 tsp kosher salt, 0.5 tsp ground black pepper, 0.5 tsp paprika, and 0.5 tsp dried oregano. These spices form the flavor base and add a subtle smokiness.

Step 2: Prepare the Garlic Butter Mixture

In a small saucepan, melt the 0.5 cup unsalted butter over low heat. Add the minced 4 cloves garlic cloves and cook for 1-2 minutes, stirring constantly, until the garlic is fragrant but not browned. Browning garlic can make it bitter, so keep the heat gentle.

Zest the 1 whole fresh lemon directly into the butter mixture, then stir in half of its juice. This adds bright, citrusy depth to the garlic butter. Remove from heat and let it sit for 1 minute to allow the flavors to meld.

Step 3: Bake the Cod with Garlic Butter

Pour the garlic butter mixture evenly over the seasoned cod fillets, ensuring each piece is well coated. Place the baking dish in the preheated oven and bake for 12-15 minutes, depending on the thickness of your fillets. The cod is done when it flakes easily with a fork and the edges turn opaque white.

Halfway through baking, baste the fillets with the accumulating butter in the dish. This ensures even flavor distribution and keeps the fish moist. Avoid overbaking—cod continues cooking slightly after removal from the oven.

Step 4: Deglaze and Garnish for Serving

Carefully transfer the cod to a serving platter. Place the baking dish on the stovetop over medium heat and add the 0.25 cup dry white wine. Simmer for 1-2 minutes, scraping up any browned bits to create a light pan sauce. This step adds a layer of complexity to the dish.

Pour the pan sauce over the cod. Garnish with the remaining lemon juice, 4 slices lemon slices, and the chopped 0.25 cup fresh parsley. The parsley adds freshness, while the lemon slices provide a visual and flavorful finish.
