How to Make Seafood Lasagna with Shrimp & Crab
- Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This ensures it’s hot and ready for your delicious lasagna.
- Cook the Noodles: Boil the lasagna noodles in a pot of salted water until they are al dente. Drain them thoroughly and set aside. This step locks in the perfect texture for your layers.
- Sauté the Seafood: In a skillet, heat olive oil over medium heat. Sauté minced garlic for about 1 minute, then add the shrimp. Cook until the shrimp turns pink, around 3-4 minutes. Fold in crab meat and seasonings, cooking for another 2-3 minutes.
- Prepare the Cheese Mixture: In a mixing bowl, combine ricotta, mozzarella, Parmesan, heavy cream, and parsley. Mix until smooth and creamy, setting the foundation for your cheesy goodness.
- Layer the Ingredients: Spread a thin layer of Alfredo sauce on the bottom of a 9×13-inch baking dish. Create layers with noodles, half of the cheese mixture, half of the seafood mixture, and a layer of Alfredo sauce. Repeat these layers, finishing with noodles and a final topping of Alfredo sauce.
- Add the Toppings: Sprinkle remaining mozzarella and Parmesan over the top, and add the breadcrumbs for a delightful crunch.
- Bake the Lasagna: Cover the baking dish with foil and bake for 25 minutes. Afterward, remove the foil and bake for an additional 10-15 minutes until the top is golden and bubbling.
- Rest Before Serving: Allow the lasagna to rest for about 10 minutes after baking. This resting period helps to set the layers, ensuring beautiful slices when it’s time to serve.
Optional: Garnish with extra chopped parsley for a fresh touch.

Expert Tips for Seafood Lasagna
- Thaw Seafood Thoroughly: Make sure to thaw and pat dry your shrimp and crab to prevent excess moisture, which can make the lasagna soggy.
- Watch Cooking Time: Avoid overcooking the seafood during preparation; just cook until pink and tender to maintain texture in your seafood lasagna with shrimp and crab.
- Layering Technique: Use a light touch when layering the ingredients. Too much pressure can compress the layers, making it difficult for the lasagna to set properly.
- Resting Period: Don’t skip the resting time after baking! Allow it to rest for about 10 minutes for cleaner, more beautiful servings.
- Adjust Spices to Taste: Feel free to adjust the red pepper flakes according to your spice preference; a little can enhance flavor, but too much can overpower the seafood.
- Make-Ahead Friendly: Prepare the seafood lasagna in advance and store it in the fridge. Bake it just before serving for an effortless meal!
Seafood Lasagna with Shrimp & Crab Variations
Feel free to get creative with this recipe and make it your own!
- Scallop Surprise: Add a handful of scallops at the end of cooking for a delightful ocean-inspired twist that’ll surprise your guests. Their tender texture pairs beautifully with shrimp and crab.
- Lobster Luxe: Swap out crab meat completely with lobster for a lavish seafood experience. The sweet and succulent meat makes every bite even more decadent.
- Cottage Cheese Swap: Use cottage cheese instead of ricotta for a lighter and slightly tangy flavor. You retain the creaminess while cutting the richness!
- Add Vegetables: Layer in some spinach or sautéed mushrooms for extra nutrition and a splash of color. These ingredients add contrast and a wonderful earthiness to the dish.
- Spice it Up: For a bolder flavor, incorporate diced jalapeños or a dash of chili powder. Adjust the heat level to suit your taste while giving your lasagna an exciting kick!
- Herb Infusion: Experiment with different herbs like dill or basil for a fresh twist. These add a unique flavor that perfectly complements the seafood.
- Alfredo Alternatives: Try using a homemade white sauce or even a tomato-based sauce for a colorful twist that can change the entire flavor profile of the dish.

Seafood Lasagna with Shrimp & Crab Recipe FAQs
What type of shrimp should I use for the seafood lasagna?
Absolutely! I recommend using fresh, peeled, and deveined shrimp for the best texture and flavor. If you prefer sustainability or budget-friendly options, frozen shrimp work fantastically as well—just remember to thaw and pat them dry before cooking.
How long can I store leftover seafood lasagna in the refrigerator?
Very! Leftover seafood lasagna can be stored in an airtight container in the refrigerator for up to 3 days. Make sure it’s well covered so it doesn’t dry out, allowing you to savor those delicious layers of shrimp and crab later.
Can I freeze seafood lasagna with shrimp and crab?
Of course! You can freeze it for up to 2 months. I recommend portioning it out, wrapping tightly in plastic wrap, followed by aluminum foil, or placing it in a freezer-safe container. This helps maintain its lovely texture even after freezing.
What should I do if my seafood seems overcooked?
Don’t worry! If you find that the seafood in your lasagna has become overcooked, it’s best to ensure that next time you cook the shrimp for just 3-4 minutes until they’re pink before incorporating them into the lasagna. This helps achieve that tender texture!
Are there any dietary considerations for this recipe?
Definitely! If anyone at your table has allergies, be mindful of shellfish. For dietary restrictions, consider substituting crab with chicken or a plant-based seafood alternative. This seafood lasagna can also be made gluten-free by using gluten-free lasagna noodles!
How do I make sure my layers stay intact when slicing the lasagna?
Great question! After baking, let your seafood lasagna rest for about 10 minutes. This crucial step allows it to set, making it much easier to cut clean slices without mixing the beautiful layers of shrimp, crab, and cheese!
