Benefits of Cooking Haddock in the Oven

Baking haddock in the oven has many advantages over other cooking methods

  • Requires minimal preparation and ingredients. All you need is haddock fillets, butter or oil, and seasonings.

  • Produces moist, flaky fish. The dry heat of the oven gently cooks the fish without drying it out.

  • Infuses flavor. Basting the fish with butter or oil as it bakes keeps it moist and allows seasonings to penetrate the flesh.

  • Easy to get consistent results. The controlled oven environment makes it simple to replicate delicious haddock time after time.

  • Hands-off cooking. Once the haddock goes in the oven, you can focus on side dishes until it’s done.

  • Saves stove space. Unlike pan frying, baking fish frees up room on the stovetop for cooking other elements of the meal.
