Ingredients for Crispy Baked Rockfish

Here’s what you’ll need to create this crispy baked masterpiece. Each ingredient plays a role in enhancing the flavor and texture of the fish:

For the fish fillets:

  • 2 rockfish fillets (about 8 oz each), 1 to 1 ½ inches thick.

For the herb mayonnaise:

  • 1 tbsp mayonnaise (regular or light).
  • 1 tsp Dijon mustard.
  • Zest of 1 lemon (reserve the lemon for roasting).
  • 2 tsp fresh herbs (basil, parsley, or a mix), finely chopped.

For the crispy breadcrumb topping:

  • ½ cup panko breadcrumbs (for extra crunch).
  • 2 tbsp fresh herbs, finely chopped.
  • 1 ½ tbsp Parmesan cheese, finely grated.
  • 1 tbsp olive oil or melted butter.
  • ½ tsp Old Bay seasoning (optional but recommended for extra flavor).
  • ¼ tsp kosher salt.

Additional items:

  • Lemon wedges for roasting.
  • Olive oil for drizzling.

Step-by-Step Preparation

1. Preheat and Prepare

Preheat your oven to 425°F (210°C). To make cleaning easier, line a baking sheet with parchment paper.

2. Prep the Fish Fillets

Use paper towels to pat dry after rinsing the fish fillets in cold water. Season both sides generously with kosher salt, freshly ground black pepper, and Old Bay seasoning if desired.

3. Mix the Herb Mayonnaise

Combine the mayonnaise, Dijon mustard, lemon zest, and chopped herbs in a small bowl. Stir until well blended. Spread this mixture evenly over the top and sides of each fillet.

4. Make the Crispy Breadcrumb Topping

Mix the panko breadcrumbs, Parmesan, chopped herbs, olive oil (or melted butter), Old Bay seasoning, and salt in another bowl. The olive oil ensures the topping browns nicely in the oven.

5. Coat the Fish

Sprinkle the breadcrumb mixture generously over the fillets, pressing gently to help it adhere. Make sure the coating is even for a consistent crunch.

6. Add Lemon Wedges

Cut the zested lemon into quarters and arrange them around the fish on the baking sheet. The roasting lemons will release their juices, adding a bright, tangy flavor to the dish.

7. Bake to Perfection

Place the baking sheet in the oven and bake for 20 minutes, or until the fish reaches an internal temperature of 140°F (60°C). If you don’t have a thermometer, check for doneness by flaking the fish with a fork—cooked fish should be opaque and flake easily.

8. Serve and Enjoy

Remove the fish from the oven, drizzle with a little extra olive oil if desired, and garnish with fresh herbs. Serve hot alongside your favorite sides.

How to Get the Perfect Crispy Finish

  1. Use Panko Breadcrumbs: These Japanese-style breadcrumbs are lighter and crispier than traditional breadcrumbs.
  2. Drizzle with Oil: A little olive oil or melted butter helps the coating brown evenly.
  3. Roast at High Heat: Baking at 425°F ensures a golden crust while keeping the fish moist inside.

Serving Suggestions

Pair your crispy baked rockfish with these simple sides for a balanced and satisfying meal:

  • Blanched Green Beans and Cherry Tomatoes: A colorful and healthy option.
  • Lemon-Herb Rice: Infuse your rice with a squeeze of fresh lemon juice and chopped parsley.
  • Zucchini and Tomato Salad: Toss thinly sliced zucchini and cherry tomatoes in a light vinaigrette.

How do I store leftovers?
