  Substitution: Fresh dill, chives, or 1 teaspoon dried parsley.

Eco Tip: Opt for MSC-certified cod to support sustainable fishing practices (Marine Stewardship Council).

How to Thaw Frozen Cod

Frozen cod is often more affordable and convenient than fresh, and it thaws quickly. Here’s the best way to thaw frozen cod for perfect results:

• Place the vacuum-sealed fish in a bowl of cold water (never use warm or hot water).

• If your fish isn’t vacuum-sealed, place it in a tightly-closed zip-top bag with as much air squeezed out as possible.

• Let the fish sit in cold water for 15–20 minutes.

• Check if it’s thawed by gently pressing—it should feel tender throughout.

• Pat dry thoroughly with paper towels before cooking.

Pro Tip: Thawing properly ensures the garlic butter adheres well and prevents watery fish (USDA Thawing Guidelines).

Step-by-Step Instructions

Prepare the Garlic Butter Mixture

The secret to this recipe’s amazing flavor is the garlic butter mixture. Here’s how to make it:

1. Preheat your oven to 400°F (200°C). Line a baking dish with parchment paper or lightly grease it.

2. In a small bowl, combine the softened butter, olive oil, minced garlic, paprika, salt, and black pepper.

3. Mix until it forms a smooth paste.

4. Add the chopped parsley and lemon juice, stirring to incorporate.

5. Set aside while you prepare the fish.

Prepare the Cod

Properly preparing the cod ensures it will cook evenly and absorb all the delicious flavors:

1. Pat the cod fillets dry with paper towels (this is key for the butter to adhere properly).

2. Slice half of your lemon into thin rounds (4–6 slices).

3. Arrange the lemon slices in a single layer in the baking dish.

4. Place the cod fillets on top of the lemon slices.

5. Spread the garlic butter mixture evenly over each fillet, covering all surfaces.

Bake to Perfection

The final step is baking the cod to flaky perfection:

1. Place the baking dish in the preheated oven.

2. Bake for 15–20 minutes, depending on the thickness of your fillets.

3. The cod is done when it flakes easily with a fork and reaches an internal temperature of 145°F (USDA Food Safety Guidelines).

4. Cut the remaining half lemon into wedges for serving.

5. Spoon any garlic butter sauce from the baking dish over the fish before serving.

Tips for Perfectly Baked Cod

Follow these professional tips to ensure your garlic butter baked cod turns out perfectly every time:

• Don’t overcook: Cod cooks quickly and continues cooking after removal from the oven. It’s done when it flakes easily and is opaque throughout.

• Pat dry thoroughly: Removing excess moisture helps the garlic butter adhere better and prevents the fish from becoming watery.

• Room temperature butter: Make sure your butter is properly softened for the best texture in your garlic butter mixture.

• Fresh garlic is best: While garlic powder works in a pinch, fresh minced garlic provides the most vibrant flavor.

• Use a meat thermometer: For perfect doneness, cod should reach an internal temperature of 145°F.

• Add crunch: Sprinkle 2 tablespoons panko breadcrumbs over the sauce before baking for a crispy texture.

Recipe Variations

Make this garlic butter baked cod your own with these creative twists:

• Keto-Friendly: Swap paprika for chili powder and add a pinch of cayenne. Serve with Cauliflower Mac and Cheese.

• Gluten-Free: Naturally gluten-free; just verify spices for cross-contamination.

• Vegan: Use plant-based cod (like tofu or jackfruit) and vegan butter. Bake for 10–12 minutes.

• Mediterranean Style: Add 1 teaspoon dried oregano and top with sliced cherry tomatoes before baking.

• Cheesy Crust: Sprinkle 2 tablespoons grated Parmesan over fillets for a golden, cheesy finish.

Storage and Reheating

• Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days.

• Freezing: Freeze cooked cod in a freezer-safe container for up to 1 month. Thaw overnight in the fridge.

• Reheating: Reheat in a 275°F oven for 8–10 minutes or microwave on low (30%) in 20-second bursts to avoid drying out.

• Repurpose Leftovers: Flake into NYC Veggie Stir Fry or a salad for a quick meal.
