Ingredients

  

For the Seafood & Noodles:

• 12 lasagna noodles regular or no-boil
• 1 pound large shrimp peeled, deveined, and chopped
• 1 pound lump crab meat fresh or canned, drained and picked over for shells
• 2 tablespoons olive oil
• 3 cloves garlic minced

For the Creamy Cheese Layer:

• 2 cups ricotta cheese whole milk is recommended for best texture
• 1 cup shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• 1 large egg
• 2 tablespoons fresh parsley chopped
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Sauce & Topping:

• 4 cups high-quality Alfredo sauce homemade or store-bought, like Classico or Bertolli
• 2 cups shredded mozzarella cheese for topping
• ½ cup grated Parmesan cheese for topping
• ½ cup seasoned breadcrumbs such as Progresso or 4C

Instructions

 

• Preheat and Prepare: First, preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with non-stick cooking spray.
• Cook the Noodles: Bring a large pot of salted water to a rolling boil. Cook the lasagna noodles according to the package directions until they are al dente (about 1-2 minutes less than the recommended time, as they will continue to cook in the oven). Drain them carefully and lay them flat on a sheet of parchment paper lightly drizzled with oil to prevent them from sticking together .
• Cook the Seafood: While the noodles are boiling, heat the olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about one minute until it becomes fragrant. Add the chopped shrimp and cook for 2-3 minutes, just until they start to turn pink. It is crucial not to overcook them at this stage. Remove the skillet from the heat and gently fold in the crab meat. Set aside .
• Mix the Cheese Filling: In a separate medium bowl, combine the ricotta cheese, 1 cup of mozzarella, ½ cup of Parmesan, the egg, chopped parsley, salt, and pepper. Stir until the mixture is completely smooth and well-blended .
• Assemble the First Layers: Now, the layering begins. Spread a thin layer of Alfredo sauce (about ½ cup) on the bottom of the prepared baking dish. This prevents the noodles from sticking. Place three lasagna noodles side-by-side over the sauce, slightly overlapping them. Spread one-third of the ricotta cheese mixture over the noodles, followed by one-third of the seafood mixture. Finally, drizzle another ½ cup of Alfredo sauce over the seafood .
• Repeat the Layers: This layering process is repeated twice more: noodles, ricotta mixture, seafood, and Alfredo sauce. It is important to ensure that the ingredients are distributed evenly for consistent flavor in every bite.
• Top and Finish: For the final layer, place the last three noodles on top. Pour the remaining Alfredo sauce over the noodles, spreading it to cover the entire surface. Sprinkle the top evenly with the remaining 2 cups of mozzarella cheese, ½ cup of Parmesan cheese, and finally, the seasoned breadcrumbs. The breadcrumbs are the secret to a deliciously crunchy, golden-brown crust .
• Bake to Perfection: Cover the baking dish tightly with aluminum foil. To prevent the cheese from sticking, spray the underside of the foil with cooking spray first . Bake for 30 minutes. After 30 minutes, carefully remove the foil and continue baking for another 15-20 minutes, or until the cheese is bubbly and the top is a deep golden brown.
• The Essential Rest: This is the most important step for success. Once removed from the oven, let the lasagna rest for at least 15-20 minutes before slicing and serving . This allows the layers to set, ensuring that beautiful, clean slices are achieved.

Pro Tips and Hacks

• Sauce Consistency: If a store-bought Alfredo sauce is used and it seems very thick, it can be thinned out with a splash of milk or seafood stock to achieve a better consistency for layering .
• Breadcrumb Boost: For an even richer flavor, the breadcrumbs can be tossed in a tablespoon of melted butter before being sprinkled on top.
• Vegetable Addition: To add color and nutrients, a cup of thawed and squeezed-dry frozen chopped spinach can be added to the ricotta cheese mixture .

Tools For This Recipe

Save

• 9×13-inch Baking Dish
• Large Pot for boiling pasta
• Large Skillet
• Mixing Bowls
• Aluminum Foil
• Measuring Cups and Spoons

TIPS FOR SUCCESS

• Do not overcook the shrimp initially. They will finish cooking in the oven; cooking them through on the stovetop will result in rubbery shrimp.
• Pat the seafood dry. Before cooking, make sure the shrimp and crab are patted dry with paper towels to remove excess moisture, which can make the lasagna watery .
• Slightly undercook the noodles. Boil the noodles for a minute or two less than the package directs. This prevents them from becoming mushy after baking.
• Always let the lasagna rest. This is non-negotiable for clean slices. The resting period allows the sauce to be absorbed and the layers to firm up .
• Keep an eye on the broiler. If the top is not golden enough after baking, it can be placed under the broiler for 1-2 minutes, but it must be watched very closely to prevent burning .

Serving Advice and Pairing Options

This lasagna is a rich and decadent dish, so it is best paired with simple, bright sides that can cut through the creaminess. A crisp green salad tossed with a light lemon vinaigrette is a classic and perfect choice . Roasted vegetables like asparagus or broccoli sautéed with a little garlic also make excellent accompaniments . To round out the meal, some warm, crusty garlic bread can be served on the side to soak up any extra Alfredo sauce .

Storage and Heating Instructions

• Refrigerator Storage: Leftover lasagna can be stored in an airtight container in the refrigerator for up to 3 days .
• Freezer Storage: This lasagna freezes beautifully. It can be frozen either before or after baking. To freeze an unbaked lasagna, it should be assembled, covered tightly with plastic wrap and then foil, and frozen for up to 3 months . To bake from frozen, it must be thawed in the refrigerator overnight first.
• Reheating Instructions: For best results, individual slices should be reheated in a 350°F oven, covered with foil, for about 15-20 minutes. The microwave can be used in a pinch, but the oven will best preserve the texture of the noodles and the crispness of the top.
