Creamy Seafood Lasagna with Shrimp and Crab: The Ultimate Comfort Food Tips, FAQ & printable recipe

Tips for success

To take this lasagna to the next level, consider adding a pinch of freshly grated nutmeg to the Alfredo sauce. Nutmeg is a classic addition to cream sauces that adds a subtle warmth and depth of flavor without overpowering the delicate seafood.

Additionally, you can enhance the texture by mixing a portion of ricotta cheese with an egg and some fresh herbs, then spreading it as an extra layer between the seafood and pasta. This adds a light, airy contrast to the rich Alfredo.

Another great tip is to use oven-ready lasagna noodles if you want to save time. However, if you choose this route, you must increase the amount of Alfredo sauce slightly or add a splash of clam juice to the sauce. Oven-ready noodles absorb a significant amount of liquid as they bake, so having extra sauce ensures the final dish remains incredibly moist and does not dry out in the oven.

Variations

• Spicy Cajun Seafood Lasagna: Add two teaspoons of Cajun seasoning to the Alfredo sauce and toss the shrimp in Cajun spices before searing for a bold, smoky kick.
• Spinach and Seafood Lasagna: Fold two cups of fresh baby spinach into the warm Alfredo sauce until wilted before assembling the layers to add color and earthy flavor.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days. Ensure it is chilled within 2 hours of cooking.

Freezer

Freezing is not recommended as the cream sauce can separate and become grainy upon thawing and reheating.

Reheat

Reheat covered with foil in a 325°F (163°C) oven for 15-20 minutes until hot and bubbling throughout.

Store any leftover seafood lasagna in an airtight container in the refrigerator for up to three days. Because this dish contains seafood and dairy, it is important to cool it down quickly and refrigerate it within two hours of cooking.

To reheat, place individual slices in an oven-safe dish, cover with foil to retain moisture, and bake at 325°F (163°C) until heated through to an internal temperature of 145°F (63°C).

You can assemble this lasagna up to 24 hours in advance. Complete all the assembly steps, cover the baking dish tightly with plastic wrap, and store it in the refrigerator.

When you are ready to bake, remove the plastic wrap, cover the dish with aluminum foil, and bake as directed. You may need to add 5 to 10 minutes to the covered baking time since the dish will be cold from the refrigerator.

Serving ideas

Serve this rich and luxurious seafood lasagna alongside a crisp, bright green salad tossed in a lemon vinaigrette. The acidity of the vinaigrette cuts through the richness of the cream sauce and cheese, creating a delightful flavor combination.

Lightly steamed asparagus or roasted green beans also make excellent side dishes that complement the delicate flavor of the shrimp and crab without competing for attention.

Accompany the meal with some warm, crusty garlic bread or a fresh baguette to soak up any extra Alfredo sauce on the plate. For beverages, a chilled glass of dry white wine, such as Pinot Grigio or Sauvignon Blanc, pairs beautifully with the seafood and cream. Garnish each individual plate with an extra sprinkle of fresh herbs and a lemon wedge for a touch of brightness.

Creamy Seafood Lasagna with Shrimp and Crab: The Ultimate Comfort Food

Prep 20 minCook 45 minRest 15 minTotal 1 h 20 minServes 8

Ingredients

• 12 lasagna noodles
• 1 lb raw shrimp, peeled and deveined
• 8 oz lump crabmeat, drained
• 3 cups creamy Alfredo sauce
• 3 cups shredded cheese, such as mozzarella
• 2 tbsp chopped fresh herbs, such as parsley

Instructions

1. Cook the lasagna noodles in a large pot of boiling water according to the package directions until al dente. Drain the noodles and lay them flat on parchment paper to prevent sticking. Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
2. Heat a large skillet over medium-high heat. Add the raw shrimp to the skillet and sear for 2 to 3 minutes, turning once, until they turn pink and opaque. Ensure they reach a safe internal temperature of 145°F (63°C). Remove the shrimp from the skillet and set aside on a clean plate.
3. Spread a thin layer of the creamy Alfredo sauce across the bottom of the greased baking dish. Arrange three lasagna noodles on top. Scatter a third of the seared shrimp and lump crabmeat over the noodles, then drizzle with a portion of the Alfredo sauce and sprinkle with a portion of the shredded cheese. Repeat this layering process twice more, finishing with a final layer of noodles topped with the remaining Alfredo sauce and cheese.
4. Cover the baking dish loosely with aluminum foil, ensuring it does not touch the cheese. Bake in the preheated oven for 25 minutes. Carefully remove the foil and bake for an additional 15 to 20 minutes, or until the cheese is bubbling and golden brown on top. For an extra golden crust, broil on high for the last 2 to 3 minutes.
5. Remove the lasagna from the oven and let it rest on a wire rack for 15 minutes before slicing. This resting period allows the layers to set so the slices hold their shape. Garnish the top with the chopped fresh herbs and serve warm.
