Creamy Seafood Lasagna with Shrimp & Crab

Ingredients

Ingredient Quantity
Lasagna noodles 12
Shrimp, peeled and deveined 1 lb (450 g)
Crab meat 1 lb (450 g)
Butter 4 tablespoons
Garlic, minced 4 cloves
All-purpose flour 1/4 cup
Whole milk, warmed 4 cups
Heavy cream 1 cup
Parmesan cheese, grated (divided) 1 cup
Mozzarella cheese, shredded 1 cup
Salt (or to taste) 1 teaspoon
Black pepper 1/2 teaspoon
Old Bay seasoning (optional) 1 teaspoon
Fresh parsley, chopped (plus extra for garnish) 2 tablespoons

Preparation Steps

  1. Bring a large pot of salted water to a boil and cook the lasagna noodles according to package directions until al dente. Drain and place them flat on parchment to prevent sticking.
  2. Melt 2 tablespoons of butter in a skillet over medium heat. Add the shrimp and cook for 2–3 minutes until just pink. Remove and set aside. Add the crab to the same pan and warm gently for 1–2 minutes, then set aside with the shrimp.
  3. In the same skillet, melt the remaining 2 tablespoons butter. Add minced garlic and cook for 1 minute until fragrant. Stir in the flour and cook for another 1–2 minutes to form a roux. Slowly whisk in the warm milk, then add the heavy cream. Let it simmer gently until thickened.
  4. Stir in 3/4 cup of the Parmesan, along with salt, pepper, Old Bay, and parsley. Adjust the seasoning to your taste and remove from heat.
  5. Spread a thin layer of sauce in a 9×13-inch baking dish. Place 4 noodles on top. Add a layer of shrimp, crab, more sauce, and a sprinkle of mozzarella. Repeat the layers until everything is used, finishing with noodles and a topping of sauce, mozzarella, and the remaining Parmesan.
  6. Preheat the oven to 350°F (175°C). Cover the lasagna with foil and bake for 25 minutes. Remove the foil and bake an additional 10–15 minutes until the top turns golden and bubbly.
  7. Let the lasagna rest for 10 minutes before slicing. Add extra parsley on top and serve warm.
