Ingredients You’ll Need

Seafood

8 ounces cooked lobster meat, chopped
- Use claw and knuckle meat if you can, since it tastes tender and sweet.
- Frozen lobster meat works fine; thaw it in the fridge and pat it dry.
12 ounces raw shrimp, peeled and deveined, tails removed
- Medium or large shrimp both work; I usually grab 21/25 size.
- Use frozen shrimp as a budget-friendly shortcut; thaw and pat dry.

Pasta & Cheese

12–15 lasagna noodles
- Use no-boil noodles for a shortcut; just add a bit more sauce so they soften.
- If you cook traditional noodles, boil them to just shy of al dente so they finish in the oven.
2 cups shredded low-moisture mozzarella cheese
- Pre-shredded works, but fresh-shredded melts smoother.
1 cup shredded provolone or fontina cheese
- Provolone adds a slightly sharper flavor; fontina melts extra creamy.
1 cup grated Parmesan cheese, divided
- Use real Parmigiano Reggiano if possible for deeper flavor.
1 ½ cups ricotta cheese
- Whole milk ricotta tastes richer and less grainy than part-skim.

Sauce & Flavor

4 tablespoons unsalted butter
3 tablespoons olive oil
4 cloves garlic, minced
1 small shallot or ½ small onion, finely minced
¼ cup all-purpose flour
3 cups whole milk, warmed
- You can swap 1 cup milk with half-and-half for extra richness.
½ cup seafood stock or low-sodium chicken broth
- Boxed stock works; choose low-sodium so you control the salt.
½ teaspoon Old Bay seasoning or similar seafood seasoning blend
½ teaspoon kosher salt, plus more to taste
¼ teaspoon black pepper
¼ teaspoon crushed red pepper flakes (optional, for a mild kick)
Zest of 1 lemon
2 tablespoons fresh lemon juice
2 tablespoons chopped fresh parsley
1 tablespoon chopped fresh basil or 1 teaspoon dried basil
1 teaspoon dried oregano

Ricotta Layer

1 ½ cups ricotta cheese (from above)
1 large egg
¼ cup grated Parmesan cheese (from the 1 cup total)
1 tablespoon chopped fresh parsley
Pinch of salt and black pepper

Pantry Shortcuts & Substitutions

Use pre-cooked lobster meat from the seafood counter to save time.
Swap lobster with extra shrimp or crab meat if lobster sits outside your budget.
Use a high-quality jarred Alfredo sauce in place of homemade white sauce on a busy night, then brighten it with lemon zest and extra garlic.
Use frozen chopped onions and jarred minced garlic if you want to cut prep time.

Equipment List

9×13 inch baking dish
Large skillet or sauté pan
Medium saucepan
Large pot for boiling noodles (if not using no-boil)
Mixing bowls
Whisk
Wooden spoon or spatula
Foil
Sharp knife and cutting board
Cheese grater

Tips & Tricks

Pat the lobster and shrimp very dry so they do not water down the sauce.
Slightly undercook the shrimp in the pan since they finish cooking in the oven.
Warm the milk before you add it to the roux so the sauce thickens smoothly.
Taste the sauce before layering and adjust salt, pepper, and lemon so it tastes slightly bold; flavors mellow in the oven.
Use a light hand with the sauce between layers so the lasagna slices cleanly and does not slide apart.
Cover the lasagna with foil for most of the bake, then uncover at the end to brown the cheese.
Let the lasagna rest 15 to 20 minutes before slicing so the layers set.
Cut the lasagna with a sharp knife and use a spatula with a thin edge to lift neat squares.
If you use no-boil noodles, add a little extra sauce around the edges so they soften fully.
Sprinkle a bit of extra Parmesan on top right before baking for a golden, slightly crispy crust.

How to Make Seafood Lasagna with Lobster and Shrimp

Step 1: Prep the Seafood

Chop the cooked lobster into bite-size pieces and place it in a bowl. Pat the shrimp dry with paper towels and cut large shrimp in half so they match the lobster size. Season the shrimp lightly with a pinch of salt, pepper, and a small sprinkle of Old Bay.

Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the shrimp in a single layer and cook 1 to 2 minutes per side until they just turn pink and opaque at the edges. Pull them off the heat while the centers still look slightly underdone, then transfer them to a plate; they finish cooking in the oven.

Step 2: Make the White Seafood Sauce

In the same skillet, add 2 tablespoons butter and 2 tablespoons olive oil over medium heat. Add the minced garlic and shallot and cook 1 to 2 minutes until they smell fragrant and look soft, but not browned. Sprinkle in the flour and stir constantly for about 1 minute until the mixture looks smooth and slightly foamy.

Slowly pour in the warmed milk while you whisk, then add the seafood stock. Whisk steadily until the sauce thickens and coats the back of a spoon, about 5 to 7 minutes. Stir in Old Bay, salt, pepper, crushed red pepper flakes if you use them, lemon zest, and lemon juice.

Taste the sauce and adjust seasoning so it tastes slightly salty and bright. Stir in half of the chopped parsley and all the dried oregano and basil. Turn the heat to low and let the sauce gently bubble for 2 to 3 more minutes, then remove it from the heat.

Step 3: Mix the Ricotta Layer

In a medium bowl, add ricotta, egg, ¼ cup Parmesan, parsley, salt, and pepper. Stir until the mixture looks smooth and creamy. Taste a tiny bit and adjust salt and pepper so it tastes flavorful on its own.

Step 4: Cook the Noodles (If Needed)

Bring a large pot of salted water to a boil. Add the lasagna noodles and cook them until they reach just shy of al dente, usually 1 to 2 minutes less than the package suggests. Stir occasionally so they do not stick.

Drain the noodles and lay them flat on a lightly oiled baking sheet or clean kitchen towel. This keeps them from sticking together while you assemble. If you use no-boil noodles, skip this step and just keep them nearby.

Step 5: Prep the Cheese Blend

In a bowl, mix the mozzarella, provolone or fontina, and the remaining Parmesan. Toss them together so they distribute evenly. This blend gives you stretch from mozzarella, flavor from Parmesan, and creaminess from provolone or fontina.

Step 6: Assemble the Lasagna

Preheat your oven to 375°F. Lightly grease a 9×13 inch baking dish with butter or olive oil. Spread a thin layer of the white seafood sauce on the bottom of the dish to keep the noodles from sticking.

Lay a single layer of noodles across the bottom, slightly overlapping if needed. Spread a thin layer of ricotta mixture over the noodles. Sprinkle a portion of the cheese blend on top, then scatter some lobster and shrimp over the cheese.

Drizzle a ladle of sauce over the seafood, just enough to coat everything lightly. Repeat the layers: noodles, ricotta, cheese blend, seafood, sauce. Aim for 3 to 4 layers, depending on your pan depth and noodle count, and finish with noodles, a generous layer of sauce, and the remaining cheese on top.

Step 7: Bake

Cover the baking dish loosely with foil, tenting it slightly so it does not touch the cheese. Bake at 375°F for about 25 to 30 minutes. Remove the foil and bake another 10 to 15 minutes until the top looks bubbly and golden brown around the edges.

If you want extra browning, switch the oven to broil for 1 to 2 minutes and watch it closely so it does not burn. Once it looks nicely browned, pull the lasagna out of the oven. Sprinkle the remaining fresh parsley over the top.

Step 8: Rest and Serve

Let the seafood lasagna rest on the counter for 15 to 20 minutes. This rest time allows the sauce to thicken and the layers to set, which helps you cut clean slices. Use a sharp knife to score portions, then slide a spatula under each piece and lift carefully.

Serve the lasagna hot, with a squeeze of fresh lemon over each slice if you like extra brightness. I usually set out extra grated Parmesan and red pepper flakes so people can customize their plates.

What to Serve with Seafood Lasagna with Lobster and Shrimp

This rich seafood lasagna pairs nicely with a crisp green salad, such as mixed greens with cucumber, cherry tomatoes, and a light lemon vinaigrette. Garlic bread or warm crusty rolls help soak up any extra creamy sauce on the plate. You can add simple roasted vegetables like asparagus, broccoli, or green beans for color and freshness.

Serve it with sparkling water, flavored seltzer, or a citrusy mocktail to cut through the richness. If you cook this for a special occasion, finish the meal with a light dessert like lemon sorbet or fresh berries so everyone leaves the table happy instead of overly stuffed.

Storage Options

Cool leftover seafood lasagna to room temperature within 1 hour, then cover tightly and store in the fridge for up to 3 days.
Reheat single portions in the microwave at 50 to 60 percent power so the seafood warms gently and the sauce does not break.
Reheat larger portions in a 325°F oven, covered with foil, for 20 to 25 minutes until hot in the center.
Freeze individual slices in airtight containers or wrapped tightly in plastic and foil for up to 2 months, then thaw overnight in the fridge before reheating.
Add a spoonful of milk or cream around the edges before reheating in the oven if the lasagna looks a bit dry from chilling or freezing.
