Step‑by‑Step Instructions for Shrimp Crab Lasagna Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven is warming, lightly grease a 9×9-inch baking dish with olive oil or butter to prevent the lasagna from sticking. This initial preparation sets the stage for a beautifully baked Shrimp Crab Lasagna that will have golden, bubbling cheese on top.
Step 2: Prepare the Lasagna Noodles
If you’re using regular lasagna noodles, bring a large pot of salted water to a rolling boil. Cook the noodles according to the package instructions until they are al dente, which usually takes about 8–10 minutes. Once cooked, drain the noodles and lay them flat on a clean surface to prevent sticking as you prepare the other ingredients.
Step 3: Sauté the Aromatics
In a large skillet, heat a drizzle of olive oil over medium heat. Add diced onion and sauté for about 3–4 minutes, or until the onion becomes translucent and fragrant. Stir in minced garlic and continue cooking for just 1 minute, allowing the garlic’s aroma to fill your kitchen. This savory base will enhance the flavors in your Shrimp Crab Lasagna.
Step 4: Cook the Seafood
Next, add the raw shrimp to the skillet and cook for approximately 3–5 minutes, stirring frequently, until the shrimp turn pink and opaque. Gently fold in the lump crab meat, allowing it to warm through for about 1–2 minutes before removing the skillet from the heat. The seafood should be tender and infused with the delicious garlicky flavor.
Step 5: Make the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once melted, whisk in an equal amount of all-purpose flour (or gluten-free flour) to create a roux. Allow the mixture to cook for 1–2 minutes, then gradually whisk in 2 cups of whole milk until the sauce thickens, about 5 minutes. The béchamel should be creamy and smooth for your Shrimp Crab Lasagna.
Step 6: Season the Béchamel
Once your béchamel sauce has thickened, stir in grated Parmesan cheese, salt, pepper, and dried parsley. Mix well until the cheese is fully melted and the sauce is seasoned to your liking. This velvety sauce is crucial for tying together the layers in your Shrimp Crab Lasagna.
Step 7: Layer the Ingredients
Begin layering your Shrimp Crab Lasagna in the prepared baking dish. Start with a spoonful of béchamel sauce, followed by a layer of lasagna noodles, then a portion of the seafood mixture and a sprinkling of mozzarella cheese. Repeat this process for two more layers, ensuring that you finish with a final layer of noodles topped with béchamel and mozzarella.
Step 8: Bake the Lasagna
Cover the baking dish loosely with aluminum foil and place it in the preheated oven. Bake for 25 minutes, allowing the flavors to meld. After 25 minutes, carefully remove the foil and bake for an additional 10 minutes. The top should be bubbly and golden brown, showing that your Shrimp Crab Lasagna is ready to be enjoyed.
Step 9: Rest Before Serving
Once out of the oven, allow the Shrimp Crab Lasagna to rest for about 10 minutes before slicing. This resting period helps the layers set, making it easier to serve and enhancing the overall flavor. While you wait, the aroma will tantalize your taste buds and draw everyone to the table.

Shrimp Crab Lasagna Recipe FAQs
What type of shrimp should I use for the Shrimp Crab Lasagna?
Absolutely! For the best results, use fresh or high-quality frozen shrimp. Look for shrimp that are wild-caught if possible, as they often have better flavor and texture. Avoid shrimp labeled as “previously frozen” if you can, as they may be less tender.
How should I store leftover Shrimp Crab Lasagna?
You can store leftover Shrimp Crab Lasagna in an airtight container in the refrigerator for up to 3 days. Just make sure to cover the dish well to prevent it from drying out. When you’re ready to enjoy it again, reheat individual portions in the microwave or bake them in the oven until warmed through.
Can I freeze Shrimp Crab Lasagna? If so, how?
Yes, you can definitely freeze Shrimp Crab Lasagna! To do this, prepare the lasagna fully (without baking it). Wrap the assembled dish tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months.

What if my béchamel sauce is too thin?
If you find your béchamel sauce is too thin, don’t worry; you can thicken it! Simply mix 1 tablespoon of flour (or cornstarch) with 1 tablespoon of cold milk to create a slurry. Gradually whisk this slurry into your saucepan over low heat while stirring constantly, until the sauce thickens to your desired consistency. This is a great fix to ensure your lasagna layers hold up beautifully!
Can I make Shrimp Crab Lasagna gluten-free?
