Step 1: Preheat Your Oven and Prepare Baking Sheet

Begin by preheating your oven to 400°F (200°C). This high temperature is key to achieving that desirable crispy crust without overcooking the delicate fish. While the oven is heating, prepare a baking sheet. Line it with parchment paper or lightly grease it with olive oil. Parchment paper is highly recommended as it prevents the fish from sticking, makes cleanup a breeze, and ensures the bottom of the fish also gets slightly crispy without burning. Using a baking sheet that is large enough to accommodate all the fish fillets in a single layer is important for even cooking and optimal crisping. Avoid overcrowding the pan, as this can steam the fish instead of baking it, resulting in a less crispy texture.

Step 2: Prepare the Flavorful Breadcrumb Coating

In a medium-sized bowl, combine the panko breadcrumbs, grated Parmesan cheese, chopped fresh parsley, dried Italian herbs, garlic powder, salt, and black pepper. Mix these dry ingredients thoroughly with a fork or whisk until they are evenly distributed. This ensures that every bite of the crispy crust is packed with flavor. The combination of panko, Parmesan, and herbs is what creates the signature crispy and flavorful topping for this baked fish. Taste the breadcrumb mixture and adjust the seasoning if necessary, adding a pinch more salt or pepper to your preference.

Step 3: Prepare the Fish Fillets

Rinse the fish fillets under cold water and pat them completely dry with paper towels. Removing excess moisture is crucial for achieving a crispy crust. If the fillets are thick, you can gently pound them to a more uniform thickness using a meat mallet or the bottom of a heavy pan. This ensures even cooking throughout the fish and prevents the edges from drying out before the center is cooked. Place the dried fish fillets on the prepared baking sheet, spacing them evenly apart.

Step 4: Drizzle with Lemon Juice and Olive Oil

Squeeze fresh lemon juice evenly over the fish fillets. The lemon juice not only adds bright, citrusy flavor but also helps to tenderize the fish and keep it moist during baking. After drizzling with lemon juice, lightly drizzle olive oil over each fish fillet. The olive oil helps the breadcrumb mixture adhere to the fish and contributes to the golden-brown color and crispiness as it bakes. Ensure you distribute the lemon juice and olive oil evenly over all the fillets for consistent flavor and texture.

Step 5: Apply the Crispy Breadcrumb Coating

Take the prepared breadcrumb mixture and generously spoon it over each fish fillet, pressing it gently to ensure it adheres well. You want to create a nice, even layer of breadcrumbs over the entire surface of each fillet. Don’t be shy with the breadcrumbs; a generous coating is what will give you that satisfying crispy texture. Make sure the breadcrumbs are evenly distributed to ensure consistent crispiness across the entire fillet.

Step 6: Bake to Golden Perfection

Place the baking sheet with the breadcrumb-coated fish in the preheated oven. Bake for 12-15 minutes, or until the fish is cooked through and the breadcrumb topping is golden brown and crispy. The exact baking time will depend on the thickness of your fish fillets. Fish is cooked through when it is opaque and flakes easily with a fork. Avoid overbaking the fish, as it can become dry. Start checking for doneness around the 12-minute mark and adjust the baking time accordingly. For thicker fillets, you may need to bake for a few minutes longer.

Step 7: Broil for Extra Crispiness (Optional)

For an extra crispy topping and a more golden-brown color, you can broil the fish for the last 1-2 minutes of cooking time. Keep a very close eye on the fish while broiling, as it can burn quickly under the broiler. Position the baking sheet in the upper rack of the oven and broil on low or medium broil setting. Watch carefully and remove the fish from the oven as soon as the breadcrumbs are nicely browned and crispy.

Step 8: Serve and Garnish

Once the fish is cooked and crispy, carefully remove the baking sheet from the oven. Let the fish rest for a minute or two before serving. Garnish with fresh lemon slices and extra chopped fresh parsley, if desired. The lemon slices not only add visual appeal but also allow for an extra squeeze of fresh lemon juice just before eating, enhancing the bright flavors of the dish. Serve immediately while the fish is hot and the crust is at its crispiest. This Crispy Baked Fish with Lemon is best enjoyed fresh from the oven.
