How to Make Baked Fish Au Gratin

  1. Preheat oven to 350°F (175°C).
  2. Lightly spray a 13x9 inch baking dish with cooking spray.
  3. Place fish fillets in the prepared baking dish.
  4. In a medium bowl, combine 1/2 cup mayonnaise, 1 cup shredded cheddar cheese, 1/4 teaspoon garlic powder, and 1/4 teaspoon salt.
  5. Mix well and spoon the cheese mixture evenly over the fish fillets.
  6. In a separate small bowl, combine 1/2 cup breadcrumbs and 1 tablespoon melted butter. Toss to coat evenly.
  7. Sprinkle the breadcrumb mixture over the cheese topping.
  8. Bake uncovered for 9-11 minutes, or until the fish is cooked through and the breadcrumbs are lightly golden.
  9. For extra crispiness, broil for 30 seconds, watching carefully to prevent burning.

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
