Step‑by‑Step Instructions for Baked Cod with Mayo and Parmesan
Step 1: Preheat the Oven
Start your cooking adventure by preheating the oven to 400°F (200°C). This ensures your Baked Cod with Mayo and Parmesan will cook evenly and develop a beautiful golden crust. While the oven warms up, prepare your baking sheet by lining it with parchment paper for easy cleanup and to prevent sticking.
Step 2: Mix the Topping
In a medium bowl, combine mayonnaise, grated Parmesan cheese, fresh lemon juice, garlic powder, paprika, salt, and pepper. Stir these ingredients together until you achieve a smooth and creamy mixture. This flavorful topping will enhance the mild taste of the cod, adding richness and depth to your dish.
Step 3: Prepare the Cod
Place the cod fillets on the parchment-lined baking sheet, ensuring they are evenly spaced for uniform cooking. Inspect the fillets for any bones and adjust their positioning for easy access when serving. The cod should be fresh and thawed if previously frozen, which ensures the best texture as it bakes.
Step 4: Apply the Topping
Using a spatula or the back of a spoon, spread the mayonnaise mixture generously over the top of each cod fillet. Make sure each fillet is fully coated, covering the fish completely and allowing the topping to create a luscious, golden crust as it bakes.
Step 5: Bake the Cod
Carefully place the baking sheet in the oven and bake your Baked Cod with Mayo and Parmesan for 12-15 minutes. Keep an eye on the fillets; they’re done when the fish flakes easily with a fork and the topping is golden brown. You’ll know it’s ready when the delicious aroma fills your kitchen!
Step 6: Garnish and Serve
Once baked, remove the cod from the oven and let it rest for a minute. For a delightful finishing touch, garnish your dish with freshly chopped parsley. This adds a pop of color and an extra layer of freshness to your hearty meal. Now your Baked Cod with Mayo and Parmesan is ready to impress!
