Storage and Reheating Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat slices gently in a 350°F oven, covered with foil, for about 20 minutes. Seafood lasagna can also be frozen: wrap it tightly before baking, freeze up to 2 months, and bake from frozen, adding about 15-20 extra minutes to the cooking time.
Serving Suggestions
Pair this seafood lasagna with a crisp green salad tossed in a lemon vinaigrette, or some roasted asparagus for a fresh and vibrant side. A chilled glass of Sauvignon Blanc or sparkling water with lemon complements the delicate seafood flavors perfectly.
Common Mistakes
Overcooking the seafood: Shrimp and crab cook quickly; avoid tough textures by cooking just until done.
Using watery sauces: Make sure the béchamel is thick enough to prevent a soggy lasagna.
Skipping the resting time: Allowing the lasagna to rest ensures it slices beautifully and retains its structure.
Recipe Variations
Lobster Version: Substitute lobster meat for crab for an even more luxurious twist.
Vegetarian Seafood Alternative: Use hearts of palm and artichokes for a “seafood-free seafood” style lasagna.
Gluten-Free Version: Replace regular noodles with gluten-free lasagna sheets.
Frequently Asked Questions
Can I use frozen seafood?
Yes, but make sure it’s fully thawed and drained to avoid excess moisture.
Can I make seafood lasagna ahead of time?
Definitely! Assemble it a day ahead, cover, refrigerate, and bake when needed.
What sauce works best?
A simple béchamel sauce works wonderfully, but a light Alfredo sauce can be used for a richer flavor.

Ingredients
- 9 lasagna noodles
- 2 tablespoons butter
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 1 pound shrimp, peeled, deveined, and chopped
- 8 ounces lump crabmeat (or imitation crab)
- 2 cups ricotta cheese
- 1 egg
- 1 cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese
- 2 cups béchamel sauce (homemade or store-bought)
- 1 tablespoon fresh parsley, chopped
- 1 teaspoon Old Bay seasoning
- Salt and black pepper, to taste
- Lemon wedges, for serving (optional)
Instructions
1- Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2- Bring a large pot of salted water to a boil. Cook lasagna noodles until al dente, drain, and set aside.
3- In a large skillet over medium heat, melt the butter. Sauté the onion until soft and translucent, about 5 minutes.
4- Add the garlic and cook for another minute, stirring often to avoid burning.
5- Stir in the shrimp and crabmeat, cooking just until the shrimp turns pink, about 3-4 minutes. Season with Old Bay, salt, and black pepper. Remove from heat.
6- In a separate bowl, mix the ricotta cheese, egg, ½ cup Parmesan, and chopped parsley until well combined.
7- To assemble, spread a thin layer of béchamel sauce on the bottom of the prepared baking dish.
8- Lay down 3 lasagna noodles.
9- Spread ⅓ of the ricotta mixture over the noodles, followed by ⅓ of the seafood mixture.
10- Drizzle a portion of béchamel sauce and sprinkle with mozzarella cheese.
11- Repeat the layers twice more, ending with a final layer of noodles, béchamel sauce, mozzarella, and the remaining Parmesan.
12- Cover with foil and bake for 30 minutes.
13- Remove foil and bake an additional 10-15 minutes until golden and bubbly.
14- Allow the lasagna to rest for 10 minutes before slicing. Serve with fresh lemon wedges for a bright finish if desired.
