Seafood Lasagna with Lobster and Shrimp tastes rich, buttery, and slightly sweet from the shellfish, with creamy cheese and a hint of garlic in every bite. It works perfectly for special-occasion dinners or cozy weekends, and you can finish the whole recipe in about 1 hour 30 minutes. I still remember the first time I served this to friends and watched everyone go completely silent for the first few bites.
Why Make This Seafood Lasagna with Lobster and Shrimp at Home
You control the quality of the lobster, shrimp, and cheese, so every layer tastes fresh and luxurious instead of heavy or bland. You also adjust the seasoning, spice level, and richness to match your crew, whether you cook for picky kids or serious seafood fans.
Homemade seafood lasagna costs far less than ordering it at a restaurant, especially when you use smart shortcuts like frozen shrimp or no boil noodles. You also get leftovers that taste even better the next day, which feels like winning dinner twice.
“This seafood lasagna with lobster and shrimp tasted like a special-occasion restaurant meal, but my family ate it in pajamas at the kitchen table.” – Jenna ★★★★★
Ingredients You Need
Seafood
- 8 ounces cooked lobster meat, chopped
- Use claw and knuckle meat for the sweetest flavor.
- Frozen cooked lobster works fine; thaw it in the fridge and pat it dry.
- 12 ounces shrimp, peeled, deveined, tails removed, chopped into bite-size pieces
- Medium or large shrimp both work; I usually grab 21–25 count.
- Frozen shrimp save time; thaw in cold water and dry well.
Pasta and cheeses
- 12 lasagna noodles
- Use no boil noodles for a shortcut; just add a bit more sauce so they soften fully.
- Regular noodles work great; cook them 1 to 2 minutes shy of package directions.
- 2 cups shredded mozzarella cheese, low moisture, part skim
- I shred a block because it melts smoother than pre-shredded.
- 1 cup shredded provolone or fontina cheese
- Provolone adds a mild tang; fontina melts super creamy.
- 1 cup grated Parmesan cheese, divided
- Use real Parmigiano Reggiano if possible for deeper flavor.
- 15 ounces whole milk ricotta cheese
- Cottage cheese works in a pinch; blend it for a smoother texture.
- 1 large egg
- This helps the ricotta layer set and slice cleanly.
Sauce and aromatics
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 small yellow onion, finely diced
- 2 cloves garlic, minced
- 3 tablespoons all purpose flour
- 3 cups whole milk, warmed
- You can use half and half for extra richness, or 2 percent milk for a lighter version.
- 1 cup seafood stock or low sodium chicken broth
- Boxed stock works; I like Kitchen Basics or a similar brand.
- 1 teaspoon Old Bay seasoning or similar seafood seasoning
- 1 teaspoon kosher salt, plus more to taste
- 1 teaspoon fresh lemon zest
- 2 tablespoons fresh lemon juice
- 1 teaspoon Dijon mustard
- 1 teaspoon smoked paprika or sweet paprika
- 1 tablespoon chopped fresh parsley
- 1 tablespoon chopped fresh basil or tarragon
- 1 pinch red pepper flakes, optional
Optional add ins
- 1 cup baby spinach, roughly chopped
- 1 cup sautéed mushrooms, sliced
- 1 small roasted red pepper, chopped
Pantry shortcuts and notes
- Use jarred roasted red peppers to save time.
- Use pre shredded cheese if you feel tired; just know it may not melt quite as silky.
- Use frozen spinach; thaw and squeeze it very dry in a towel.
Equipment list
- 9 by 13 inch baking dish
- Large skillet or sauté pan
- Medium saucepan
- Large pot for boiling noodles
- Whisk
- Mixing bowls
- Sharp knife and cutting board
- Aluminum foil
Tips & Mistakes
- Salt the pasta water generously so the noodles carry flavor.
- Undercook lasagna noodles slightly so they finish in the oven and stay firm.
- Dry the lobster and shrimp well so they do not water down the sauce.
- Cut seafood into small, even pieces so each bite gets a mix of lobster and shrimp.
- Avoid overcooking the seafood; keep it just opaque since it cooks more in the oven.
- Warm the milk before you add it to the roux so the sauce thickens smoothly.
- Whisk the sauce constantly after you add flour so it does not clump or scorch.
- Taste the sauce before assembly and adjust salt, lemon, and seasoning right then.
- Spread a thin layer of sauce on the bottom of the dish so noodles do not stick.
- Do not stack thick clumps of seafood in one spot; scatter it evenly across each layer.
- Cover the lasagna with foil for most of the bake so the top does not burn.
- Remove the foil for the last 10 to 15 minutes so the cheese browns and bubbles.
- Let the lasagna rest 15 to 20 minutes before slicing so it sets and slices cleanly.
- Use a sharp knife and a spatula to lift squares instead of a spoon that tears layers.
- Chill leftovers in shallow containers so they cool quickly and stay safe.
How to Make Seafood Lasagna with Lobster and Shrimp
Step 1: Prep the seafood and noodles
Pat the lobster and shrimp very dry with paper towels, then chop them into bite-size pieces. Season them lightly with salt, a pinch of Old Bay, and a squeeze of lemon juice. Bring a large pot of salted water to a boil and cook lasagna noodles until just shy of al dente, then drain and lay them flat on a lightly oiled sheet pan.
Step 2: Sauté aromatics
Heat olive oil and 1 tablespoon butter in a large skillet over medium heat. Add the diced onion and cook until it turns soft and translucent, about 5 to 7 minutes, then stir in the garlic and cook 1 minute more. Add the shrimp and lobster, cook just until the shrimp turn pink and opaque, about 2 to 3 minutes, then transfer the seafood mixture to a bowl and set it aside.
Step 3: Make the creamy seafood sauce
In the same skillet or a medium saucepan, melt the remaining 2 tablespoons butter over medium heat. Whisk in the flour and cook, whisking constantly, for 1 to 2 minutes until the mixture smells nutty and looks pale golden. Slowly pour in the warm milk while you whisk, then add the seafood stock and continue to whisk until the sauce thickens and coats the back of a spoon, about 5 to 7 minutes.
Step 4: Season the sauce
Stir in Old Bay, salt, smoked paprika, Dijon mustard, lemon zest, and lemon juice. Taste and adjust seasoning with more salt, lemon, or red pepper flakes if you like a little heat. Stir in the chopped parsley and basil, then fold in the cooked seafood mixture so the sauce coats every piece.
Step 5: Mix the ricotta layer
In a medium bowl, combine ricotta, 1 egg, 1 cup shredded mozzarella, 2 tablespoons Parmesan, a pinch of salt, and a small handful of chopped parsley. Stir until the mixture looks smooth and creamy. If you use spinach, fold it in now so it spreads easily between layers.
Step 6: Assemble the lasagna
Preheat the oven to 375 degrees Fahrenheit and lightly grease a 9 by 13 inch baking dish. Spread a thin layer of seafood sauce over the bottom of the dish, then place a layer of noodles on top, slightly overlapping. Dollop one third of the ricotta mixture over the noodles and spread it gently, then spoon some seafood sauce over that and sprinkle with a mix of mozzarella, provolone, and Parmesan.
Repeat the layering process two more times: noodles, ricotta, seafood sauce, shredded cheeses. Finish with a final layer of noodles, a generous amount of sauce, and the remaining cheeses on top. If you use roasted peppers or mushrooms, tuck them into the middle layer so they stay juicy.
Step 7: Bake
Cover the baking dish loosely with foil, tenting it slightly so the cheese does not stick. Bake for 25 to 30 minutes, then remove the foil and bake another 10 to 15 minutes until the top turns golden and the edges bubble. If the top needs more color, switch the oven to broil for 1 to 2 minutes and watch it closely.
Step 8: Rest and slice
Remove the seafood lasagna with lobster and shrimp from the oven and place it on a cooling rack. Let it rest for 15 to 20 minutes so the layers settle and the cheese firms up. Slice into squares with a sharp knife and lift each piece with a spatula.
Variations I’ve Tried
I swap half the shrimp for scallops and sear them quickly before layering for a sweet, buttery twist. I also make a tomato cream version by stirring a cup of crushed tomatoes into the sauce and cutting the milk by about one third. For a lighter weeknight version, I use fewer noodles, more spinach, and extra mushrooms for a lasagna that still tastes rich but sits a little lighter.
Sometimes I go full luxury and use all lobster with a splash of extra lemon and extra Parmesan on top. For spice lovers, I add a spoonful of Calabrian chili paste or a bit more red pepper flakes to the sauce. You can also build individual lasagnas in small baking dishes, which feels fancy and solves the problem of fighting over corner pieces.
How to Serve Seafood Lasagna
Serve seafood lasagna with lobster and shrimp with a simple green salad dressed in a light vinaigrette so the freshness balances the creamy sauce. Add garlic bread or warm crusty bread so everyone can scoop up the extra sauce from their plates. A side of roasted asparagus, green beans, or broccoli keeps the meal colorful and bright. For drinks, offer sparkling water with lemon, iced tea, or a citrusy mocktail to cut through the richness.
How to store
- Cool leftovers to room temperature within 1 hour, then cover tightly and store in the fridge for up to 3 days.
- For freezing, cut the lasagna into portions, wrap each piece in plastic wrap, then foil, and freeze for up to 2 months.
- Reheat single portions in the microwave at medium power, covered, until hot in the center, then crisp the top in a toaster oven if you like.
- Reheat a larger portion in a covered baking dish at 350 degrees Fahrenheit for 20 to 30 minutes, then uncover for the last 5 minutes to re-melt and brown the cheese.
