Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
lasagna noodles
shrimp, peeled and deveined
crab meat
butter
garlic
onion
all-purpose flour
milk
heavy cream
parmesan cheese
mozzarella cheese
ricotta cheese
salt
black pepper
parsley
lemon juice (optional)

Directions

I start by cooking the lasagna noodles according to the package instructions, then I drain and set them aside.

In a pan, I melt butter over medium heat and sauté the chopped onion until soft. I add garlic and cook briefly until fragrant. Then I add the shrimp and cook until they turn pink. I gently fold in the crab meat and cook for another minute before removing everything from the heat.

In the same pan, I prepare a creamy sauce by adding more butter, then stirring in flour to form a roux. I slowly pour in milk and cream while whisking to avoid lumps, letting the sauce thicken. I mix in parmesan cheese, salt, and pepper until smooth.

To assemble, I spread a layer of sauce on the bottom of a baking dish. I add a layer of noodles, followed by the seafood mixture, ricotta, mozzarella, and more sauce. I repeat the layers until all ingredients are used, finishing with sauce and a generous topping of mozzarella and parmesan.

I bake the lasagna in a preheated oven at 180°C (350°F) for about 35–40 minutes, until bubbly and golden on top. I let it rest for a few minutes before slicing and serving.

Servings and timing

I usually get about 6 servings from this recipe.
Preparation time: 20 minutes
Cooking time: 40 minutes
Total time: 1 hour

Variations

I sometimes add spinach between the layers for extra color and nutrition.
I like to use a mix of cheeses such as fontina or gouda for a deeper flavor.
For a lighter version, I replace part of the cream with more milk.
I occasionally add a pinch of chili flakes for a subtle heat.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. When I reheat it, I cover it with foil and warm it in the oven at a low temperature to keep it from drying out. If I’m in a hurry, I use the microwave, though I prefer the oven for better texture.
