How To Make Seafood Lasagna With Shrimp And Crab
- Prepare the noodles:
- Cook lasagna noodles until just al dente about 7 minutes as they will continue cooking in the oven. To prevent sticking lay them flat on a baking sheet lightly drizzled with olive oil while preparing other components.
- Prepare the seafood mixture:
- Heat your skillet until you can feel warmth hovering your hand above it before adding olive oil. Sauté the garlic until you can smell its aroma but before it browns about 60 seconds. Add shrimp ensuring they're patted dry first for better browning and cook until they transform from translucent gray to opaque pink with slight firmness. Gently fold in the delicate crab meat just to warm it through avoiding overmixing which would break up the beautiful lumps.
- Create the cheese mixture:
- Combine the cheeses with heavy cream until you achieve a smooth yet slightly textured consistency. The mixture should be spreadable but not runny enough to hold its shape when spread. The parsley adds little flecks of color throughout this creamy layer.
- Assemble the layers:
- Start with enough sauce to coat the bottom of your baking dish this prevents sticking and adds moisture to the bottom noodles. When layering be methodical about coverage ensuring no dry spots particularly at the edges. Press gently on each layer to remove air pockets that could create unstable sections in your finished lasagna.
- Bake to perfection:
- The initial covered baking period allows all flavors to meld and components to cook through without excessive browning. Removing the foil for the final cooking period develops that signature golden top with crispy edges. Watch carefully during this uncovered period as cheese can go from perfectly golden to overly browned quickly.
- Rest before serving:
- This resting period is crucial as it allows the layers to set making for cleaner slices. The temperature also becomes more pleasant for eating while flavors continue to develop.

The sweet crab meat is truly the star ingredient in this dish. My grandmother was from Maryland and always said that good crab should taste like it was plucked from the ocean that morning. The first time I served this lasagna to her she closed her eyes while eating and declared it "worthy of Sunday dinner" which was her highest culinary compliment.
Balancing Seafood Flavors
Seafood requires thoughtful seasoning to enhance without overwhelming its natural delicate flavors. The garlic and parsley in this recipe complement both shrimp and crab without masking their sweetness. If you're using particularly fresh seafood consider reducing the salt slightly to let the natural briny notes shine through.
Make Ahead Options
This lasagna can be assembled up to 24 hours before baking. Simply cover tightly with plastic wrap then foil and refrigerate. Remove from refrigerator 30 minutes before baking to take the chill off and add about 10 minutes to the covered baking time. The flavors actually develop beautifully during this resting period creating an even more flavorful final dish.
Affordable Alternatives
While fresh seafood creates the most luxurious version budget conscious cooks can still enjoy this dish. Quality frozen shrimp works well when properly thawed and patted dry. Imitation crab can substitute for fresh crab meat though the texture and flavor will differ slightly. The rich cheese mixture and Alfredo sauce will still create a delicious result even with these substitutions.

Serving Suggestions
Pair this rich lasagna with a crisp green salad dressed simply with lemon vinaigrette to cut through the creaminess. Garlic bread makes a traditional side but consider roasted asparagus or broccolini for a vegetable option that complements the seafood flavors. A chilled glass of Pinot Grigio or unoaked Chardonnay makes the perfect beverage pairing.
