Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

12 lasagna noodles
1 lb shrimp, peeled and deveined
1 lb crab meat
2 cups ricotta cheese
2 cups shredded mozzarella cheese
1 cup grated Parmesan cheese
4 cups Alfredo sauce
1 cup heavy cream
2 cloves garlic, minced
2 tbsp olive oil
1 tbsp fresh parsley, chopped
1 tsp salt
1 tsp black pepper
1/2 tsp red pepper flakes
1/2 cup breadcrumbs

Directions

1. Preheat the oven to 375°F (190°C). Cook the lasagna noodles in salted water until al dente. Drain and lay them flat to prevent sticking.
2. In a skillet, heat olive oil over medium heat. Sauté garlic for about 1 minute until fragrant. Add shrimp and cook until just pink, 3–4 minutes. Stir in crab meat, salt, black pepper, and red pepper flakes. Cook another 2–3 minutes, then remove from heat.
3. In a mixing bowl, combine ricotta, 1 cup mozzarella, 1/2 cup Parmesan, heavy cream, and parsley. Mix until smooth and creamy.
4. Spread a thin layer of Alfredo sauce on the bottom of a 9×13-inch baking dish. Add a layer of noodles, then spread one-third of the cheese mixture, followed by one-third of the seafood mixture, and drizzle with Alfredo sauce. Repeat the layers two more times, ending with noodles and sauce on top.
5. Top with the remaining mozzarella and Parmesan. Sprinkle breadcrumbs evenly over the surface. Cover with foil and bake for 25 minutes. Remove the foil and bake for another 10–15 minutes, until the top is golden and bubbling.
6. Let the lasagna rest for 10 minutes before slicing and serving. Garnish with extra parsley if desired.

Variations

• Replace the crab with additional shrimp or include small scallops for a different seafood combination.
• Cottage cheese may be used instead of ricotta, though the texture will be lighter.
• For a stronger cheese profile, add extra Parmesan between layers.
• Skip the breadcrumbs and use only cheese for a softer, melt-only topping.
• Add sautéed spinach or mushrooms for more texture and nutrients.

Storage/Reheating

Refrigerate leftovers for up to 2 days in an airtight container. When reheating, add a splash of cream or Alfredo sauce to keep the lasagna moist. Warm in the oven at 300°F (150°C) or microwave gently.
To freeze, cool completely, wrap well, and freeze for up to 1 month. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use imitation crab instead of real crab?

Yes, imitation crab can be used, though the flavor will be milder than fresh crab.

How can I keep the lasagna from becoming watery?

Drain seafood thoroughly and avoid overcooking it. Allow the lasagna to rest before slicing to help the layers set.

Can I make this seafood lasagna ahead of time?

Yes, assemble it up to a day in advance, cover, refrigerate, and bake when ready to serve.

What sides pair best with this dish?

Light salads, steamed vegetables, or garlic bread complement the creaminess well.

Can I freeze the lasagna after baking?

Yes, once cooled, portion and freeze for up to 1 month. Thaw in the fridge and reheat gently.

What type of Alfredo sauce works best?

A thick, good-quality jarred Alfredo or a homemade version made with butter, cream, and Parmesan works perfectly.

Can I use precooked shrimp?

Yes, but add them at the very end of step 2 to avoid overcooking.

How do I get a crispier topping?

Use panko breadcrumbs and broil for 1–2 minutes at the end, watching closely.

Can I lighten the dish by reducing the cream?

You may use half-and-half instead of heavy cream, though the texture will be less rich.

What size baking dish is required?

A standard 9×13-inch dish fits the layers perfectly and ensures even baking.
