Step‑by‑Step Instructions for Baked Garlic Butter Cajun Cod
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Baked Garlic Butter Cajun Cod cooks evenly and achieves that perfect flaky texture. While the oven heats, let’s prepare the baking dish for your fish.
Step 2: Prepare the Baking Dish
Lightly grease a baking dish with cooking spray or a small amount of butter. This step is crucial to prevent the cod from sticking and to help it develop a beautiful golden crust. Set the greased baking dish aside while you prepare the cod fillets.
Step 3: Dry and Arrange the Cod
Pat the cod fillets dry with paper towels to remove excess moisture, which helps to enhance the cooking process. Arrange the dried fillets in the prepared baking dish in a single layer, ensuring each piece has space to cook evenly and absorb all those delicious flavors.
Step 4: Mix the Seasoning Blend
In a small bowl, whisk together the melted unsalted butter, minced garlic, Cajun seasoning, paprika, onion powder, salt, black pepper, and lemon juice. This robust mixture will coat the cod and infuse it with rich, inviting flavors. Make sure the butter is fully incorporated with the spices for an even coating.
Step 5: Coat the Cod
Using a basting brush or a spoon, generously apply the garlic butter mixture over the cod fillets. Ensure each piece is well-coated, allowing the mixture to seep into the fish, enhancing its taste while it bakes. Visualize that luscious, buttery glaze glistening on the fillets before they go into the oven!
Step 6: Bake the Cod
Place the prepared baking dish into your preheated oven and bake for 12-15 minutes. You’ll know the Baked Garlic Butter Cajun Cod is done when it flakes easily with a fork and has turned a light golden color. Keep an eye on the fish to avoid overcooking, which can dry it out.
Step 7: Garnish and Serve
Once the cod is beautifully baked, remove it from the oven and garnish with freshly chopped parsley for a pop of color. Serve your flavorful dish with lemon wedges on the side to brighten the flavors even more. Enjoy your delightful meal that’s sure to impress!
