Step‑by‑Step Instructions for Baked Lemon Butter Cod
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (204°C). This ensures that your Baked Lemon Butter Cod is cooked evenly and perfectly. Use an oven thermometer if you have one to guarantee accuracy. As the oven heats, it’s a great time to gather all your ingredients and equipment, ensuring a smooth cooking process ahead.
Step 2: Prepare the Butter Sauce
In a medium mixing bowl, combine melted unsalted butter, minced garlic, garlic powder, onion powder, lemon zest, lemon juice, and red pepper flakes. Stir until well mixed, creating a fragrant, luscious sauce. This mixture will coat the fish, infusing it with zesty and buttery flavors. Allow this garlic-infused sauce to rest while you prepare the cod fillets.
Step 3: Coat the Cod
Pat the cod fillets dry with a paper towel to enhance their texture. Dip each fillet into the prepared butter mixture, ensuring they are fully coated. This step is crucial for maximizing flavor in your Baked Lemon Butter Cod. Once coated, set the fillets aside on a plate as you finish your preparation.
Step 4: Arrange in the Baking Dish
Take a 9×13-inch baking dish and lay the coated cod fillets inside, placing them evenly apart. Pour any remaining butter sauce over the top, allowing the excess to drench the fillets. This will promote a wonderfully rich flavor and moisture while baking, ensuring your dinner is succulent and satisfying.
Step 5: Add Lemon Slices
For an extra burst of freshness, layer lemon slices over and around the cod fillets. The slices not only enhance the presentation but also contribute more lemony flavor as they roast. You’ll want the cod to sit amid this citrusy goodness, creating a beautiful and aromatic dish.
Step 6: Bake the Cod
Transfer the baking dish to your preheated oven and bake for 10-15 minutes. Keep an eye on the fillets; they should become opaque and flake easily with a fork. Additionally, use a food thermometer to check that the internal temperature reaches 145°F (63°C), ensuring that your Baked Lemon Butter Cod is cooked safely and perfectly.
Step 7: Garnish and Serve
Once the cod is baked to perfection, remove it from the oven and let it rest for a couple of minutes. Before serving, sprinkle with freshly chopped parsley for a pop of color and flavor. This simple yet elegant garnish highlights the beauty of your Baked Lemon Butter Cod, making it ready for an impressive presentation at the dinner table.
