Ingredients

Why this recipe works

Searing the shrimp in butter before assembling the lasagna ensures they develop a rich, caramelized exterior while remaining tender and succulent. This initial sear locks in the natural juices of the shellfish, preventing them from becoming rubbery during the baking process. Additionally, using the same skillet to sear the shrimp captures all the flavorful browned bits, infusing the entire dish with a deep, savory seafood essence that elevates the final flavor profile.

Layering the lasagna with a combination of high-moisture cheese and a rich white sauce creates the perfect balance of texture and flavor. The cheese melts into a stretchy, luxurious blanket that binds the seafood and pasta together, while the creamy sauce adds a velvety richness that cuts through the savory elements.

Baking the dish at a high temperature blisters the cheese crust, sealing in the moisture of the seafood layers below and keeping the pasta perfectly tender.

Notes and substitutions

Selecting high-quality seafood is paramount for this recipe. Fresh, wild-caught shrimp provide the best texture and sweet flavor, though high-quality frozen shrimp that have been thawed work exceptionally well too.

For the crab, lump crab meat is highly recommended because of its sweet flavor and large, beautiful pieces that stand up well to baking. Avoid canned crab meat if possible, as it tends to be too salty and lacks the delicate texture required for this decadent lasagna.

For the pasta, traditional lasagna noodles that are boiled beforehand offer the best structure and chew. If you prefer a shortcut, high-quality oven-ready lasagna sheets can be substituted, though you may need to add a splash of extra liquid to the white sauce to ensure there is enough moisture for the noodles to cook completely in the oven.
