Description

A creamy, comforting twist on classic lasagna—layers of tender noodles, ricotta-based cheese filling, succulent shrimp and crab, all smothered in a homemade white sauce for an elegant seafood spin.


Ingredients

  • 1 pound lasagna noodles
  • 4 tablespoons butter
  • 1/4 cup plus 1 tablespoon flour
  • 3 cups milk
  • 1 cup grated parmesan cheese, divided
  • 1/2 tablespoon salt (or to taste)
  • 1/4 tablespoon ground white pepper
  • 1 (15 oz) container ricotta cheese
  • 1 egg
  • 2 teaspoons minced garlic
  • 2 1/2 cups grated mozzarella cheese, divided
  • 1/2 cup chopped parsley
  • 1 pound cooked shrimp (chopped if large)
  • 1 pound crabmeat

Instructions

  1. Cook lasagna noodles according to package directions, drain, and set aside.
  2. In a saucepan over medium heat, melt butter. Whisk in flour until smooth, then gradually add milk, whisking continuously until thickened. Remove from heat and stir in 1/2 cup parmesan, salt, and white pepper.
  3. In a bowl, combine ricotta, egg, garlic, 2 cups mozzarella, and parsley until smooth. In a separate bowl, mix shrimp and crab.
  4. In a greased 9×13-inch baking dish, layer: 1 cup sauce, 3 noodles, a third of the ricotta mixture, and a third of the seafood mixture. Repeat layers two more times. Finish with remaining sauce and top with remaining mozzarella and parmesan.
  5. Cover and bake at 350°F for 30 minutes. Uncover and bake an additional 10 minutes, or until bubbly and golden.
  6. Let rest for 10–15 minutes before slicing and serving.

Notes

  • Reduce salt if sensitive to sodium.
  • Can be assembled a day ahead and baked when ready.
  • Freezes well for up to 3 months; thaw fully before reheating.
  • Swap in cooked chicken or other seafood for variety.
  • Try vegetables like peas, carrots, or mushrooms for extra flavor.
  • Use zucchini ribbons or no-boil noodles for a twist.
