Halibut Alaska is a classic seafood dish that features tender halibut fillets topped with a creamy and flavorful sauce, then baked until golden and bubbly. The sauce is made with mayonnaise, Dijon mustard, lemon juice, and Parmesan cheese, which adds a tangy and cheesy element to the dish. Serve the Halibut Alaska with a side of steamed vegetables or roasted potatoes for a complete and satisfying meal.
