How to Make Shrimp Crab Lasagna
Step 1 – Prepare the seafood mixture
Heat olive oil and butter in a skillet over medium heat. Sauté garlic and shallots for 2–3 minutes until fragrant, then cook shrimp until pink and opaque. Remove shrimp and gently warm the crab meat in the same pan. Combine with shrimp and season with salt, pepper, and lemon zest.
Step 2 – Make the béchamel sauce
Melt butter in a saucepan and whisk in flour to form a roux. Slowly whisk in warm milk and cook until thickened. Stir in Parmesan cheese and season with salt and white pepper.
Step 3 – Prepare the cheese filling
Mix ricotta cheese with chopped parsley, basil, salt, and lemon juice in a bowl until creamy and combined.
Step 4 – Cook the lasagna noodles
Prepare the noodles according to package instructions if needed. Drain and lay flat to prevent sticking.
Step 5 – Assemble the lasagna
Spread a thin layer of béchamel sauce in a baking dish. Add noodles, ricotta mixture, seafood mixture, béchamel, and mozzarella cheese. Repeat the layers and finish with mozzarella and Parmesan on top.
Step 6 – Bake until bubbly and golden
Cover with foil and bake at 375°F (190°C) for 30 minutes. Remove foil and bake another 10–15 minutes until golden and bubbling. Rest for 10 minutes before serving.
What to Serve Them With
Serve with a crisp green salad for a fresh contrast to the creamy lasagna.
Garlic bread or warm dinner rolls pair perfectly with the rich sauce.
A side of roasted asparagus or green beans adds color and balance to the meal.
Variations / Substitutions
Swap shrimp for scallops or lobster for a different seafood twist.
Use cottage cheese instead of ricotta if preferred.
