Step‑by‑Step Instructions for Shrimp and Crab Seafood Lasagna
Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This ensures your Shrimp and Crab Seafood Lasagna bakes evenly and reaches that perfect bubbly, golden crust. While the oven warms up, gather your ingredients so you’re ready for the next steps.
Step 2: Prepare the Lasagna Noodles
In a large pot, boil water and cook the lasagna noodles until al dente, following the package instructions, usually about 8–10 minutes. Drain the noodles and lay them flat on a towel or parchment paper to prevent sticking, allowing them to cool slightly while you prepare the filling.
Step 3: Sauté Garlic and Seafood
In a spacious skillet, heat 2 tablespoons of olive oil over medium heat. Add 2 minced garlic cloves and sauté for about 30 seconds until fragrant. Then, toss in 1 pound of peeled and deveined shrimp and cook for 3–4 minutes, until the shrimp turn pink. Stir in 1 pound of lump crab meat along with salt, pepper, and optional red pepper flakes, cooking for an additional 2–3 minutes while mixing thoroughly.
Step 4: Mix the Cheese Filling
In a large mixing bowl, blend together 2 cups of ricotta cheese, 1 cup of mozzarella, ½ cup of freshly grated Parmesan, 1 cup of heavy cream, and half of the chopped parsley. Stir until the mixture is smooth and combined, creating a rich, creamy filling to complement the seafood in your lasagna.
Step 5: Assemble the Lasagna Layers
In a 9×13-inch baking dish, spread a thin layer of Alfredo sauce on the bottom to prevent sticking. Begin layering by placing lasagna noodles over the sauce, followed by half of the cheese mixture, the seafood blend, and more Alfredo sauce. Repeat this layering process until you have three layers, finishing with noodles and sauce on top.
Step 6: Add Toppings and Bake
Sprinkle the remaining mozzarella and Parmesan over the top layer of sauce, followed by the breadcrumbs for added crunch. Cover the dish with aluminum foil to lock in moisture and bake in the preheated oven for 25 minutes. This will ensure the lasagna cooks thoroughly.
Step 7: Final Baking Without Foil
After 25 minutes, carefully remove the foil to allow the cheese to brown. Bake the Shrimp and Crab Seafood Lasagna for an additional 10–15 minutes, watching for that irresistible bubbling and golden color on top, which indicates it’s ready to serve.
Step 8: Rest and Garnish
Once out of the oven, let the lasagna rest for about 10 minutes before cutting. This resting period helps the layers set and makes serving easier. Sprinkle the remaining parsley on top for a fresh touch, and your delicious Shrimp and Crab Seafood Lasagna is ready to delight your family and friends!

Shrimp and Crab Seafood Lasagna Recipe FAQs
What kind of shrimp should I use for this recipe?
Absolutely! When choosing shrimp, opt for fresh or frozen, peeled, and deveined shrimp. Look for shrimp labeled “wild-caught” for superior flavor. If purchasing fresh, it should smell like the ocean—not fishy—and be firm to the touch.
How should I store leftovers of the Shrimp and Crab Seafood Lasagna?
For leftovers, store them in an airtight container in the fridge for up to 3 days. Make sure to cover it tightly with foil or plastic wrap to retain that delicious, creamy texture. I often gently reheat individual portions in the microwave for a quick and tasty meal.
Can I freeze Shrimp and Crab Seafood Lasagna?
Certainly! You can freeze unbaked shrimp and crab seafood lasagna. Wrap it tightly in plastic wrap and then foil, and it can last for up to 2 months in the freezer. When you’re ready to bake it, just remove it from the freezer and pop it right into the oven. Increase the bake time by about 10-15 minutes to ensure it heats through perfectly.
What should I do if my lasagna is watery?
Very! If your lasagna ends up watery, ensure that you properly drain your seafood before mixing. Additionally, avoid using excess sauce in the layering process. If you find yourself with a watery bottom layer, consider allowing the dish to rest longer after coming out of the oven; this helps set everything together.
Are there any dietary considerations for this dish?
Of course! If you have seafood allergies or are cooking for someone who does, it’s best to substitute the shrimp and crab with grilled chicken or roasted vegetables for a completely different but still delightful lasagna. Always check ingredients for hidden allergens, especially in sauces and cheeses.
Can I prepare the Shrimp and Crab Seafood Lasagna ahead of time?
Yes, indeed! You can assemble your shrimp and crab seafood lasagna a day ahead. Just cover it tightly and store in the refrigerator before baking. When you’re ready to cook it, simply remove it from the fridge and add an additional 10-15 minutes to your bake time to ensure it’s heated throughout.
