Step 1: Cook the Pasta

Step 3: Make the White Sauce
- In a saucepan, melt butter over medium heat.
- Add flour and stir constantly for 1–2 minutes to form a roux (thick paste).
- Slowly pour in the milk while whisking to avoid lumps.
- Add heavy cream and let it cook until the sauce thickens.
- Season with a little salt, pepper, and some Parmesan cheese.
Step 4: Layer the Lasagna
- Preheat your oven to 375°F (190°C).
- In a baking dish, spread a thin layer of white sauce at the bottom.
- Place a layer of lasagna noodles over it.
- Add some of the shrimp and crab mixture.
- Spread ricotta cheese, followed by white sauce, then sprinkle mozzarella cheese.
- Repeat the layers until all ingredients are used, finishing with noodles, sauce, mozzarella, and Parmesan on top.
Step 5: Bake the Lasagna

- Remove foil and bake for another 10–15 minutes until the top is golden and bubbly.
