Preheat your oven to 375°F (190°C).

Cook the lasagna noodles in a large pot according to package instructions. Once they’re al dente, drain and set aside.

In a skillet over medium heat, sauté the chopped shrimp in a drizzle of olive oil until they turn pink—about 3-4 minutes.

In a large baking dish, start layering: place a layer of lasagna noodles, then add the sautéed shrimp, followed by crab meat and your choice of ricotta and marinara sauce.

Repeat these layers until you’ve used up all ingredients, ensuring that you finish with mozzarella on top.

Cover the dish with foil and bake for 25 minutes. After that, remove the foil and bake for another 15 minutes until the cheese is bubbly and golden.

Let the lasagna cool slightly before cutting to serve.
