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). While the oven heats, lightly grease a baking dish with cooking spray or a bit of olive oil to ensure that the fish doesn’t stick. This step sets the stage for your flavorful Baked Garlic Butter Cajun Cod to finish beautifully and evenly.
Step 2: Prepare the Cod Fillets
Take your fresh cod fillets and pat them dry with paper towels, removing any excess moisture. Place them in the greased baking dish, making sure they’re laid out in a single layer. This allows the heat to circulate evenly, ensuring each fillet cooks perfectly and flakes easily when done.
Step 3: Make the Garlic Butter Mixture
In a small mixing bowl, melt 3 tablespoons of unsalted butter, either in the microwave or on the stove. Once melted, add in 3 cloves of minced garlic, 2 teaspoons of Cajun seasoning, 1 teaspoon of paprika, ½ teaspoon of onion powder, ½ teaspoon of salt, and ¼ teaspoon of freshly cracked black pepper. Whisk these ingredients together until well combined, creating a rich and flavorful sauce.
Step 4: Coat the Cod
Evenly brush or spoon the garlic butter mixture over the cod fillets, ensuring each piece is generously coated. The mixture will not only enhance the flavor but will also create a lovely golden-brown crust as it bakes. You can let it sit for a moment to allow the flavors to meld while you prepare for baking.
Step 5: Bake the Cod
Place the baking dish in your preheated oven and bake the cod for 12–15 minutes. You’ll know it’s ready when the fish flakes easily with a fork, and the top is beautifully golden. Keep an eye on it; the cod should look slightly opaque and firm once cooked through.
Step 6: Garnish and Serve
Once the cod is out of the oven, sprinkle 2 tablespoons of chopped fresh parsley on top for a burst of color and freshness. Serve it immediately with lemon wedges on the side, enhancing the flavors of your Baked Garlic Butter Cajun Cod, and enjoy a wholesome meal that’s packed with robust taste!
