Ingredients You’ll Need for This Seafood Lasagna with Shrimp and Crab

• 9 no-boil lasagna noodles
• 1 pound large shrimp, peeled and deveined
• 8 ounces lump crab meat, picked over for shells
• 3 cups whole milk
• 4 tablespoons unsalted butter
• 4 tablespoons all-purpose flour
• 1 cup grated Parmesan cheese, divided
• 1 ½ cups ricotta cheese
• 2 cups shredded mozzarella cheese, divided
• 3 cloves garlic, minced
• 1 small shallot, finely chopped
• 2 tablespoons olive oil
• 1 teaspoon lemon zest
• 1 tablespoon fresh parsley, chopped
• ½ teaspoon salt, plus more to taste
• ½ teaspoon black pepper
• Pinch of nutmeg (optional)

Substitution tips: If you can’t find lump crab meat, canned crab works well in a pinch—just drain it thoroughly. For a dairy-free version, swap the butter and milk with plant-based alternatives and use vegan cheeses, though the texture will differ slightly. You can also substitute the no-boil noodles with traditional ones; just be sure to boil them according to package instructions before assembling.

Steps to Create Your Seafood Lasagna with Shrimp and Crab

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Heat olive oil in a large skillet over medium heat. Add the minced garlic and chopped shallot, sautéing until fragrant and translucent, about 2-3 minutes.
3. Add the shrimp to the skillet, season with salt and pepper, and cook until just pink, about 2 minutes per side. Remove shrimp and set aside.
4. In the same skillet, gently warm the crab meat for about 1-2 minutes to infuse flavor, being careful not to break up the lumps. Remove and set aside with the shrimp.
5. To make the béchamel sauce, melt butter in a medium saucepan over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes until it turns a light golden color, stirring constantly.
6. Slowly pour in the milk, whisking constantly to avoid lumps. Continue cooking and whisking until the sauce thickens and coats the back of a spoon, about 6-8 minutes.
7. Remove from heat and stir in half of the Parmesan cheese, lemon zest, nutmeg (if using), and a pinch of salt and pepper. Set aside.
8. In a medium bowl, combine ricotta cheese with half of the mozzarella and chopped parsley. Season lightly with salt and pepper.
9. Now, assemble the lasagna: start with a thin layer of béchamel sauce at the bottom of the dish to prevent sticking.
10. Layer three lasagna noodles over the sauce, followed by a layer of the ricotta mixture, then a portion of shrimp and crab, and a generous spoonful of béchamel sauce.
11. Repeat the layering process two more times, ending with noodles topped with béchamel sauce and the remaining mozzarella and Parmesan cheeses.
12. Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes or until the cheese is golden and bubbly.
13. Let the lasagna rest for 10 minutes before serving to allow the layers to set.

One thing I’ve learned from years of cooking with my family is that letting a lasagna rest before serving makes all the difference—it helps the layers meld together so every forkful holds its shape and flavor beautifully.

Tips for Making the Best Seafood Lasagna with Shrimp and Crab

Over the years, standing in kitchens from my grandmother’s cozy nook to my own bustling home, I’ve picked up a few tricks that make this seafood lasagna truly shine:

• Don’t overcook the seafood: Shrimp and crab cook quickly, so it’s best to undercook the shrimp slightly before baking. They’ll finish cooking in the oven without turning rubbery.
• Use fresh lemon zest: It adds a bright freshness that cuts through the richness of the cheese and sauce, balancing the flavors beautifully.
• Choose quality cheeses: Freshly grated Parmesan and good mozzarella make a noticeable difference in texture and flavor. It’s worth the extra effort to shred your own cheese.
• Be generous with seasoning: Seafood can taste bland if not properly seasoned. Season each layer lightly with salt and pepper to build flavor.
• Layer thoughtfully: Ensure each layer has a good balance of noodles, seafood, and sauce. This keeps every bite interesting and delicious.

I’ve found these small details transform a good meal into a memorable one—something that brings my family back to the table again and again.

Serving Suggestions and Pairings

When I serve this Seafood Lasagna with Shrimp and Crab, I like to keep the sides light and fresh to complement the richness of the dish. A crisp green salad with a lemon vinaigrette is a favorite—something simple to brighten the plate and add a bit of crunch. Roasted asparagus or sautéed green beans tossed in olive oil and garlic also make wonderful partners.

For a wine pairing, a chilled glass of Sauvignon Blanc or Pinot Grigio works beautifully, cutting through the creamy layers with a crisp, refreshing finish. And don’t forget a warm, crusty loaf of bread to soak up any leftover sauce—that’s always a hit at my table.

In our home, these meals are about more than just eating—they are moments where we slow down and savor being together. The seafood lasagna has a way of making those moments feel special without fuss.

Storage and Reheating Tips

One of the reasons I love making this seafood lasagna is how well it holds up as leftovers. Whether you’re meal prepping for the week or want to enjoy it again the next day, here’s how to keep it tasting fresh and delicious:

• Allow the lasagna to cool completely before covering it tightly with foil or plastic wrap.
• Store in the refrigerator for up to 3 days.
• For longer storage, freeze in an airtight container for up to 2 months. It’s best to freeze individual portions for easy reheating.
• To reheat, bake covered at 350°F (175°C) until heated through, about 20-25 minutes. If reheating frozen portions, thaw overnight in the fridge before baking.
• Microwaving works in a pinch—just cover with a microwave-safe lid or wrap and heat in 1-2 minute intervals until warm.

These tips come from many busy nights when I wanted a comforting, home-cooked meal without the effort of starting from scratch. It’s the kind of recipe that makes weeknight dinners feel a little more indulgent, even on the toughest days.
