How to Make Seafood Lasagna Shrimp Crab – Step-by-Step

Step 1: Prepare the Pasta

1. Bring a large pot of salted water to a boil.
2. Add the lasagna noodles and cook until just al dente.
3. Drain and lay flat on parchment paper to prevent sticking.

Tip: Overcooked noodles = mushy lasagna. Stop at “al dente.”

Step 2: Cook the Seafood

1. In a large skillet, heat olive oil over medium heat.
2. Add minced garlic and sauté for 1 minute until fragrant.
3. Add shrimp and cook 3–4 minutes until pink and opaque.
4. Stir in crab meat, salt, pepper, and red pepper flakes. Cook 2 more minutes.
5. Remove from heat.

Important: Do not overcook the shrimp — they’ll finish in the oven.

Step 3: Mix the Cheese Filling

1. In a mixing bowl, combine:
   • Ricotta
   • 1 cup mozzarella
   • ½ cup Parmesan
   • Heavy cream
   • Parsley
2. Season with salt and pepper to taste.
3. Stir until creamy and smooth. Add a splash more cream if needed.

This is the heart of the lasagna – rich, creamy, and packed with flavor.

Step 4: Assemble the Lasagna

1. Preheat oven to 375°F (190°C).
2. Spoon a thin layer of Alfredo sauce on the bottom of a 9×13” baking dish.
3. Begin layering:
   • Pasta noodles
   • Cheese mixture
   • Cooked seafood
   • Drizzle of Alfredo sauce
4. Repeat layers two more times.
5. Top final layer of noodles with Alfredo, remaining mozzarella and Parmesan, and breadcrumbs.

Step 5: Bake and Serve

1. Cover with foil and bake for 25 minutes.
2. Remove foil and bake an additional 15 minutes, until golden and bubbly.
3. Let sit 10 minutes before slicing.
4. Garnish with fresh parsley and serve warm.

Pro Tips & Cooking Secrets

• Use fresh lump crab for the best texture and flavor.
