Seafood Lasagna with Shrimp and Crab Ingredients
For the Lasagna
• Lasagna Noodles – A hearty base; cook until al dente to keep them firm during baking.
• Shrimp (1 lb) – Choose medium to large for a satisfying texture; imitation crab can be used for a milder flavor.
• Crab Meat (1 lb) – Fresh lump crab is ideal for rich flavor; canned or imitation crab makes a budget-friendly substitute.
For the Cheese Mixture
• Ricotta Cheese (2 cups) – Creamy and tangy, it forms the luscious filling.
• Shredded Mozzarella Cheese (2 cups) – Perfect for meltiness; use whole milk for a richer flavor.
• Grated Parmesan Cheese (1 cup) – Brings salty depth; freshly grated packs the most punch.
For the Sauce and Seasoning
• Alfredo Sauce (4 cups) – The creamy backbone; opt for a thicker variety to prevent sogginess.
• Heavy Cream (1 cup) – Enhances creaminess; can swap with half-and-half for a lighter version.
• Garlic (2 cloves, minced) – Fresh garlic is crucial for aromatic allure.
• Olive Oil (2 tbsp) – Use for sautéing; it enhances the overall flavor of the dish.
• Fresh Parsley (1 tbsp, chopped) – A fresh garnish adds color and brightness.
• Salt (1 tsp) – Essential for flavor enhancement; taste and adjust as necessary.
• Black Pepper (1 tsp) – Freshly ground adds warmth and depth.
• Red Pepper Flakes (½ tsp, optional) – For a hint of heat, customize to your liking.
For the Topping
• Breadcrumbs (½ cup) – Creates a crunchy golden topping that contrasts beautifully with the creamy layers.
Step‑by‑Step Instructions for Seafood Lasagna with Shrimp and Crab
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Seafood Lasagna with Shrimp and Crab bakes evenly and thoroughly. Set a timer for the preheating so you can easily move to the next step once it’s ready.
Step 2: Prepare the Lasagna Noodles
Cook the lasagna noodles in a large pot of salted boiling water for 8-10 minutes until they are al dente. This will help the noodles maintain their structure during baking. Once cooked, drain them in a colander and lay them flat on a clean surface to prevent sticking.
Step 3: Sauté the Garlic
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the minced garlic and sauté for about 1 minute, stirring frequently until fragrant. Take care not to let it burn, as that can lead to a bitter taste in your seafood lasagna.
Step 4: Cook the Shrimp
Add 1 pound of medium to large shrimp to the skillet and cook for 3-4 minutes, stirring occasionally until they turn pink and opaque. This is your visual cue that the shrimp is fully cooked. Once done, stir in the crab meat and season with salt, black pepper, and optional red pepper flakes. Cook for another 2-3 minutes, then remove from heat.
Step 5: Mix the Cheese Filling
In a medium mixing bowl, combine 2 cups of ricotta cheese, 1 cup of shredded mozzarella, ½ cup of grated Parmesan, 1 cup of heavy cream, and 1 tablespoon of chopped parsley. Using a spatula, mix these ingredients until smooth and well blended, creating a rich filling for your lasagna.
Step 6: Create the First Layer
Spread a thin layer of Alfredo sauce on the bottom of a 9×13-inch baking dish to prevent sticking. This first layer sets the stage for building your Seafood Lasagna with Shrimp and Crab, ensuring that your noodles emerge with a delightful texture.
Step 7: Layer the Ingredients
Begin layering by adding 3-4 cooked lasagna noodles over the sauce. Follow this with ⅓ of the cheese mixture, then ⅓ of the seafood mixture, and a drizzle of Alfredo sauce. Repeating this process, layer two more times until all ingredients are used, ending with a final layer of noodles on top.
Step 8: Finalize Before Baking
Finish your lasagna by generously covering the top layer of noodles with the remaining Alfredo sauce, then sprinkle with the rest of the shredded mozzarella and grated Parmesan. For an added crunch, distribute ½ cup of breadcrumbs evenly over the top.
Step 9: Bake the Lasagna
Cover your baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes, then carefully remove the foil and continue baking for an additional 10-15 minutes. The cheese should be bubbly and golden brown, signaling that your seafood lasagna is ready to be enjoyed.
Step 10: Let It Rest
Once baked to perfection, remove the lasagna from the oven and allow it to rest for at least 10 minutes. This resting time helps the layers set, making it easier to serve. Garnish with freshly chopped parsley for a pop of color and flavor before serving.
Make Ahead Options
These Seafood Lasagna with Shrimp and Crab are a fantastic choice for busy weeknights or gatherings! You can assemble the entire lasagna up to 24 hours in advance by layering the noodles, cheese mixture, and seafood filling, then covering tightly with foil and refrigerating. To maintain quality, use a thick Alfredo sauce to prevent sogginess and avoid overcooking the shrimp. When you’re ready to enjoy this delightful dish, simply preheat the oven and bake it straight from the fridge for about 35-40 minutes, ensuring everything is heated through and bubbly. This prep-ahead method transforms cooking from a chore into a breeze, letting you savor every bite!

Seafood Lasagna with Shrimp and Crab Recipe FAQs
What type of shrimp should I use for the seafood lasagna?
Absolutely! For the best texture and flavor, I recommend using medium to large shrimp. This helps create a delightful experience where each bite is filled with satisfying seafood goodness. If you can’t find fresh shrimp, feel free to use frozen shrimp—just be sure to thaw it properly before cooking.
How do I store leftover seafood lasagna?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. This will help maintain the creamy texture and lock in those delicious flavors. When storing, ensure the container is sealed tight to keep it fresh!

What should I do if my lasagna turns out watery?
Don’t worry, it happens! If you notice your lasagna is watery, the most likely culprit is a thin Alfredo sauce or overcooked noodles. To combat this issue, ensure your Alfredo sauce is thick enough before layering. You can also drain any excess liquid from the seafood mixture before mixing it with the cheese. Next time, consider undercooking your noodles slightly, as they will continue to absorb moisture while baking.
Is this seafood lasagna suitable for those with shellfish allergies?
Unfortunately, if someone has a shellfish allergy, this dish would not be safe for them to eat due to the shrimp and crab. However, for an alternative version, you can create a hearty vegetarian lasagna with layers of roasted vegetables and a creamy cheese filling instead!
