Creamy seafood lasagna with shrimp and crab is everything I want in a celebratory meal layers of tender pasta succulent seafood and velvety Alfredo sauce all baked until bubbly and comforting It is the perfect main dish for holidays birthdays or when you want to treat yourself to something special yet still achievable for a home cook
The first time I made this seafood lasagna my friends could not stop raving about it It brings the elegance of seafood to a familiar cozy pasta bake and quickly became my signature dinner party dish
Ingredients
- Lasagna noodles: starchy wide noodles provide a classic comfort food base for the luscious layers look for ones that cook up sturdy and do not tear easily
- Shrimp: peeled and deveined provide sweet tender bites use firm medium sized shrimp and avoid any with a fishy odor for best results
- Crab meat: adds a delicate richness and a touch of luxury I prefer lump crab meat for its texture but even claw or imitation crab can work if needed
- Ricotta cheese: gives the filling lightness and classic creaminess choose a whole milk ricotta for smoother consistency
- Mozzarella cheese: melts into beautiful strings of cheesy goodness and binds the layers use freshly shredded for best melt
- Parmesan cheese: packs savory umami notes and a golden crust freshly grated always gives better flavor
- Alfredo sauce: forms the creamy backbone use a quality jarred sauce or homemade for deeper flavor
- Heavy cream: enriches the filling and ensures every bite stays creamy and not dry
- Garlic: minced adds aromatic depth make sure it smells fresh for the best result
- Olive oil: is used to sauté garlic and seafood developing savory notes opt for extra virgin if possible
- Fresh parsley: brightens and balances the rich dish Look for vibrant green leaves
- Salt: seasons and enhances all the flavors use sea salt if you have it
- Black pepper and red pepper flakes: add mild warmth and a little kick try fresh cracked black pepper for better fragrance
- Breadcrumbs: provide a satisfying crunchy topper use panko or fresh for extra texture
Instructions
- Boil the Pasta:
- Cook lasagna noodles in plenty of salty water just until tender according to package directions Carefully drain and lay flat on a towel to prevent sticking
- Prep and Cook the Seafood:
- In a large skillet warm olive oil over medium heat until shimmering Stir in minced garlic and let it get aromatic for about a minute Add shrimp and let them sizzle gently for roughly three to four minutes until they turn pink and opaque Add the crab meat next and sprinkle with salt black pepper and red pepper flakes Let everything mix together for another two to three minutes so the flavors blend Remove from heat
- Mix the Cheese Filling:
- In a mixing bowl stir together ricotta cheese one cup mozzarella half a cup Parmesan heavy cream and fresh parsley until you get a thick creamy mixture that holds together
- Assemble the Lasagna:
- Spread a thin layer of Alfredo sauce on the bottom of your baking dish to keep the noodles from sticking Lay down a layer of noodles Spoon a third of the cheese mixture on top then scatter a third of the seafood mixture over that Drizzle generously with Alfredo sauce Repeat this process two more times building up those luscious layers Finish with a final sheet of noodles and plenty of Alfredo sauce on top
- Top and Bake:
- Sprinkle the top layer with the rest of your mozzarella and Parmesan For a golden crunch shower on the breadcrumbs too Cover with foil and bake for about twenty five minutes then carefully remove the foil and continue baking ten to fifteen minutes until the top is golden and bubbly
- Rest and Serve:
- Give your lasagna ten full minutes on the counter before slicing This step keeps the layers tidy when you serve Garnish with fresh parsley for a bright finish

Crab is my favorite ingredient here because it feels like a luxury but is so easy to work with My favorite lasagna memory is the first time my sister helped assemble the layers we both laughed at our uneven stacking but the result was so delicious nobody cared
Storage Tips
Let the lasagna cool completely before refrigerating Cover the dish tightly with foil or transfer slices to airtight containers It stays fresh in the fridge for up to three days To freeze let cool cut into single servings and wrap each in plastic then foil Thaw overnight in the fridge and reheat in a covered baking dish at a low oven temp to preserve creaminess
Ingredient Substitutions
No crab on hand Swap in more shrimp or even firm white fish like cod For a lighter option try low fat ricotta and reduced cream You can use gluten free lasagna noodles for those with sensitivities If Alfredo is not your thing try a simple cream sauce flavored with a bit of lemon zest for freshness
Serving Suggestions
This seafood lasagna shines with a simple green salad tossed in a zesty vinaigrette and some crusty bread For extra color serve with lemon wedges or a sprinkle of fresh chives at the table For a dinner party pair with sparkling white wine
Cultural and Historical Context
Seafood lasagna brings Italian American flair to the classic Northern Italian lasagna Originally lasagna was a clever way to stretch bits of meat and cheese with noodles Once Italian immigrants arrived in coastal US regions they married local seafood bounty with the comfort of pasta bakes making it a centerpiece for special gatherings
Seasonal Adaptations
You can swap in seasonal seafood like lobster or scallops Spring peas and fresh herbs add lovely brightness to the filling In colder months add wilted spinach or a layer of sautéed mushrooms for earthiness
Success Stories
A friend once made this for her holiday open house and was surprised when even the pickiest kids cleaned their plates every morsel was gone before dessert It is my personal go-to for family reunions because one pan easily serves a crowd
Freezer Meal Conversion
Double the recipe and bake in two smaller pans Serve one and freeze the other for a future busy night Just remember to add a splash of cream or Alfredo before reheating to keep every slice moist

There is honestly nothing like digging into a homemade seafood lasagna It is creamy a little decadent but approachable enough for any comfort food craving Every time I make it I am reminded that sharing a beautiful meal with people you love is always worth a little extra effort
