Key Ingredients & Their Roles

Shrimp: Main seafood element; use fresh or frozen for convenience.
Imitation crab: Affordable and adds a subtle sweetness; can replace with cooked lobster for a richer flavor.
Cottage cheese: Provides creaminess and adds protein; substitute ricotta for different texture.
Parmesan cheese: Enhances umami flavor; use aged for deeper taste.

How to Make Seafood Lasagna

Gather all ingredients and preheat the oven to 375°F, filling your kitchen with anticipation.
Cook the lasagna noodles in salted water until just pliable, about 6-7 minutes. Drain and place on oiled parchment to avoid sticking.
In a large skillet, melt 1 Tbsp butter over medium heat, sautéing onion, celery, and garlic until softened, about 5 minutes.
Mix in chopped shrimp, imitation crab, spinach, lemon juice, and Cajun seasoning; cook until shrimp turn pink, about 3 minutes.
Stir together cottage cheese and parsley, setting aside for layering later.
In a saucepan, melt ¼ cup butter and whisk in flour, cooking for one minute. Gradually add milk while whisking until the mixture thickens, about 5-6 minutes.
Mix in Parmesan and Old Bay seasoning, ensuring a silky consistency that invites hearty scoops.
Prepare your baking dish by greasing it lightly. Start with a thin layer of the white sauce at the bottom, then alternate layers of noodles, seafood mixture, dollops of cottage cheese, and mozzarella, finishing with three noodles topped with remaining sauce and mozzarella.
Cover tightly with foil and bake for 30 minutes; remove foil and bake another 15-20 minutes, broiling for 3-5 minutes to achieve a golden cheese layer at the end.
Let the Seafood Lasagna rest for 10-15 minutes, enhancing the flavors before slicing. Feel free to garnish with parsley before serving.

Pro Tips & Troubleshooting

For a lighter sauce, consider using half-and-half instead of whole milk; it still maintains a lovely creaminess.
A common mistake is overcooking the shrimp, leading to a rubbery texture; cook just until they turn pink.
Feel free to add seasonal vegetables like zucchini or bell peppers for extra color and flavor.
This lasagna easily doubles; use a larger dish and adjust cooking time as needed.

Storage & Make-Ahead Guide

Store leftovers in the fridge for up to 4 days or freeze for up to 3 months. When reheating, use the oven at 350°F for about 20 minutes or until heated through. After testing, I found that freezing slices and reheating maintained the flavors beautifully.

Serving Suggestions

Serve your Seafood Lasagna alongside a crisp side salad for a refreshing contrast. You might also pair it with Maple Balsamic Brussels Sprouts, which adds a delightful sweetness.
