Ingredients

  • 1 cup grated Cheddar cheese
  • 1/4 cup bread crumbs
  • 1 teaspoon paprika
  • 1 teaspoon minced parsley
  • 1 tablespoon diced onion
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 2 pounds haddock

Instructions

  1. Heat the oven to 400°F (200°C).
  2. In a small bowl, combine the grated Cheddar cheese, bread crumbs, paprika, minced parsley, diced onion, salt, and pepper.
  3. Place each haddock fillet on individual squares of greased aluminum foil.
  4. Spoon the crumb mixture over each fish fillet.
  5. Seal the foil securely around each piece.
  6. Bake in the preheated oven for 25 to 30 minutes or until the fish flakes easily.

Tips & Substitutions

For a richer flavor, consider adding a splash of lemon juice or a dash of hot sauce to the crumb mixture. If you don't have Cheddar cheese, Gruyère or mozzarella can be great substitutes. For a healthier version, swap out the bread crumbs for crushed whole grain crackers or oats. Be sure to check the haddock for bones before cooking for a smoother dining experience.

Serving Suggestions

Serve the Haddock Au Gratin with a fresh side salad or steamed vegetables for a complete meal. It pairs beautifully with Cape Anne Chowder for a seafood feast. For added flair, garnish with additional minced parsley or a squeeze of lemon juice. A light white wine, such as Sauvignon Blanc, complements the dish nicely.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the haddock in a preheated oven at 350°F (175°C) for about 10-15 minutes, covered with foil to retain moisture. Avoid reheating in the microwave, as it can make the fish rubbery.

Frequently Asked Questions

Can I use frozen haddock for this recipe?

Yes, you can use frozen haddock. Just ensure to thaw it completely before cooking to ensure even cooking. If using frozen fish, it may take a few extra minutes in the oven to bake fully.

What can I substitute for bread crumbs?

You can substitute bread crumbs with crushed crackers, panko, or even oats for a gluten-free option. Each alternative may slightly change the texture, but they will still provide a delicious topping.

How can I tell when the haddock is done cooking?

The haddock is done when it flakes easily with a fork and is opaque throughout. Typically, baking for 25 to 30 minutes at 400°F will achieve this, but check a few minutes early to avoid overcooking.
