Creamy Seafood Lasagna with Shrimp and Crab Tips, FAQ & printable recipe

Tips for success

To achieve clean, restaurant-style slices, use a very sharp chef's knife or a serrated utility knife. Wipe the blade clean with a damp paper towel between each cut to prevent the cheese and cream sauce from dragging.

A sturdy, wide offset spatula is the best tool for lifting the slices out of the baking dish, ensuring that the bottom noodle layer remains intact and the towering structure stays perfectly upright on the plate.

If the top cheese layer begins to brown too quickly before the center of the lasagna is hot, loosely tent the baking dish with aluminum foil for the remaining cooking time.

This reflects the direct heat while allowing the interior to continue baking. Always remove the foil for the last five minutes of baking to ensure the top crust achieves that desirable, crispy texture and beautiful golden color.

Variations

• Spicy Cajun Seafood Lasagna: Toss the shrimp in Cajun seasoning and stir a pinch of cayenne pepper into the Alfredo sauce for a bold, spicy kick.
• Spinach and Seafood Lasagna: Layer fresh baby spinach between the pasta sheets to add a vibrant color and fresh flavor that pairs beautifully with the sweet crab.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 days, cooling them within 2 hours of cooking.

Freezer

Freeze tightly wrapped assembled lasagna or individual baked slices for up to 2 months; thaw overnight in the fridge.

Reheat

Reheat individual slices in the oven at 350°F (175°C) covered with foil for 15-20 minutes until piping hot.

Store any leftover seafood lasagna in an airtight container in the refrigerator for up to three days. To preserve the moisture and prevent the pasta from drying out, press a piece of plastic wrap directly onto the cut surface of the remaining lasagna before sealing the container.

Because seafood is highly perishable, prompt refrigeration within two hours of cooking is essential for food safety.

This dish can be assembled up to twenty-four hours in advance. Build the lasagna completely in the baking dish, cover it tightly with plastic wrap, and store it in the refrigerator. When ready to bake, remove the plastic wrap, cover the dish with foil, and add ten minutes to the initial covered baking time to account for the cold temperature of the dish.

Serving ideas

Serve this rich, creamy lasagna alongside a crisp, acidic green salad tossed with a light lemon vinaigrette. The bright acidity of the dressing cuts through the decadence of the heavy cream and cheese, balancing the palate between bites.

Steamed green vegetables like asparagus or roasted broccolini also make excellent accompaniments, adding a fresh contrast of color and texture to the plate.

Warm, crusty garlic bread or artisanal sourdough is a must-have accompaniment for soaking up any extra Alfredo sauce left on the plate. Present the lasagna on dark, elegant plates to make the golden-brown cheese crust and vibrant green parsley garnish pop visually. Serve each slice immediately while still warm and steaming for the ultimate comfort food experience.

Creamy Seafood Lasagna with Shrimp and Crab

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

Ingredients

• 12 lasagna noodles
• 3 cups Alfredo sauce, store-bought or made ahead
• 1 lb raw pink shrimp, peeled and deveined
• 1 tbsp seafood seasoning
• 12 oz lump crab meat, picked through
• 3 cups shredded cheese
• 2 tbsp fresh parsley, chopped for garnish

Instructions

1. Bring a large pot of salted water to a boil. Add the lasagna noodles and cook according to package instructions until al dente. Drain the noodles and lay them flat on parchment paper to prevent sticking.
2. Toss the raw pink shrimp with the seafood seasoning. Heat a nonstick skillet over medium-high heat and cook the seasoned shrimp for 3 to 4 minutes, stirring occasionally, until they turn opaque and pink, reaching a safe internal temperature of 145°F (63°C). Remove from the heat and set aside.
3. Spread a thin layer of Alfredo sauce in a 9x13-inch baking dish. Lay three cooked lasagna noodles on top. Evenly distribute a portion of the lump crab meat, seasoned pink shrimp, Alfredo sauce, and shredded cheese. Repeat these layers, ending with a final layer of noodles topped with the remaining Alfredo sauce and shredded cheese.
4. Preheat the oven to 375°F (190°C). Cover the baking dish with foil and bake for 30 minutes. Remove the foil and bake for an additional 10 minutes until the golden cheese is bubbling under the heat and the top is lightly browned.
5. Remove the lasagna from the oven and let it rest for 15 minutes to set. Garnish the top with fresh chopped parsley and extra succulent shrimp before slicing into clean squares and serving.
