  • Soy sauce – 3 tablespoons
  • Olive oil – 2 tablespoons
  • Ground ginger – 1 teaspoon
  • Brown sugar – 1 teaspoon

Pantry Notes

  • Substitute fish: If mahi mahi is not available, similar firm white fish such as halibut, cod, or swordfish can be used.
  • Mayonnaise alternatives: Greek yogurt or sour cream can be substituted for a lighter version.
  • Breadcrumbs: Both panko and regular breadcrumbs add crunch. Use gluten-free if desired.

Step-by-Step Directions

  1. Preheat oven to 425°F (218°C). If using a ginger glaze variation, preheat to 400°F.
  2. Prepare fish: Rinse mahi mahi fillets and pat dry. Place in a lightly greased baking dish.
  3. Season: Squeeze fresh lemon juice over fish. Sprinkle evenly with garlic salt and black pepper.
  4. Topping:
    • Mix mayonnaise with finely chopped onions. Spread over fillets to cover the surface.
    • Sprinkle bread crumbs on top, pressing lightly so they adhere to the mayonnaise.
  5. Bake: Place dish in oven and bake for 25 minutes, or until fish flakes easily with a fork.
  6. Serve: Remove from oven and serve hot. This recipe yields approximately 4 servings.

Alternate Ginger Glaze Method

  1. Season fillets with salt and pepper, arrange in a shallow baking dish.
  2. In a bowl, whisk together orange juice, soy sauce, olive oil, ground ginger, and brown sugar.
  3. Pour glaze over the fish. Cover and marinate in refrigerator for 20 minutes.
  4. Bake at 400°F for 13–15 minutes, until fish flakes apart. Garnish with parsley or green onions if desired.

Baking Tips & Tricks

  • For even cooking, select fillets of similar thickness.
