Ingredients

Makes one 9x13 inch lasagna · serves 8

Pasta and Seafood

  • 1 box lasagna noodles, cooked according to package directions
  • 1 lb shrimp, peeled and deveined
  • 1 lb lump crab meat, picked over for shells

  • 2 cups creamy white sauce, store-bought or made ahead

Cheese

  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated parmesan cheese
Contains: gluten, crustaceans, fish, milk

Why this recipe works

The method relies on a high-quality creamy sauce, which provides a stable and rich foundation. By using a pre-made or prepared white sauce, the lasagna achieves a velvety consistency that clings perfectly to the pasta and seafood layers, ensuring each bite is moist and flavorful.

Layering the ingredients in a specific order allows the flavors to meld beautifully during the baking process. The cheese acts as a binder, while the sauce keeps the pasta tender.

The final rest period is essential as it allows the internal structure of the lasagna to firm up, resulting in perfect, clean slices.

Notes and substitutions

For the best results, use fresh shrimp and high-quality lump crab meat. If you cannot find lump crab, backfin or claw meat can be used, though the texture will be slightly different.

The cheese choice is also flexible; if you prefer a sharper taste, you can add a small amount of provolone to the mozzarella.

The equipment used matters for even cooking. For the baking dish, a ceramic or glass 9x13 inch pan is perfect as it retains heat well, ensuring the lasagna stays warm during the resting period before serving.

Ensure the seafood is cleaned thoroughly before layering to maintain the best quality.

  • lump crab meat: imitation crab meat can be used if preferred for a more budget-friendly option
  • creamy white sauce: alfredo sauce can be substituted for a similar creamy consistency
