Equipment

- Measuring cups & spoons
- Optional: food processor for smooth béchamel
Ingredients
- 1 lb shrimp, peeled and deveined
- 8 oz lump crab meat
- 9–12 lasagna sheets (no-boil or traditional)
- 1 ½ cups ricotta cheese
- 1 ½ cups shredded mozzarella
- ½ cup grated Parmesan cheese
- 3 tablespoons butter
- 3 tablespoons flour
- 2 cups milk
- 1 teaspoon garlic, minced
- 1 shallot, finely chopped
- ½ teaspoon thyme
- Salt and pepper, to taste
- Optional: 1 cup sautéed spinach, mushrooms, or roasted red peppers
Instructions
- Preheat oven to 375°F (190°C). Grease baking dish.
- Prepare shrimp: peel, devein, and pat dry. Lightly season.
- Flake crab meat, removing any shells or cartilage.
- Make béchamel: melt butter, whisk in flour to form a roux, slowly add milk, and cook until thickened. Stir in salt, pepper, and nutmeg. Fold in cheeses until smooth.
- Optional: sauté aromatics and vegetables until tender.
- Layering: spread a thin layer of sauce in the baking dish, cover with pasta sheets, sauce, shrimp, crab, ricotta, and mozzarella. Repeat layers, finishing with sauce and mozzarella/Parmesan on top.
- Cover with foil and bake 25–30 minutes, then uncover for 10–15 minutes to brown.
- Rest 10–15 minutes before slicing. Garnish with parsley if desired.
Notes
- Use fresh or high-quality frozen seafood for best results.
- Adjust seasoning gradually; cheese and béchamel contribute saltiness.
- For gluten-free, use certified gluten-free pasta and thickened sauce with cornstarch.
- For low-carb, replace pasta with thin zucchini or eggplant slices.
- Let the lasagna rest before slicing to set layers and prevent spilling.
- Optional variations: add lobster, scallops, or a pinch of crushed red pepper for extra flavor.
