Key Ingredients & Their Roles

Shrimp: Adds a tender texture and a sweet ocean flavor; use fresh if possible for best results.

Imitation Crab: Budget-friendly seafood choice that brings a mild taste; can be replaced with real crab if desired.
Cottage Cheese: Provides creaminess and a subtle tang; for a richer flavor, consider ricotta.
Parmesan Cheese: Enhances the sauce with salty, nutty notes; fresh grated is recommended for best melting results.

How to Make Seafood Lasagna

Gather all necessary ingredients and set your oven to 375°F (190°C).
Cook the lasagna noodles in salted water until they’re al dente, about 8-10 minutes. Drain and lay them flat on oiled parchment to avoid sticking.
In a large skillet, melt 1 tablespoon of butter over medium heat. Sauté diced onion, celery, and garlic until softened, about 5-6 minutes. Introduce the shrimp and imitation crab, cooking until the shrimp turns pink.

Combine the cottage cheese and parsley in a small bowl, setting it aside for layering.
In a medium saucepan, melt ¼ cup of butter. Whisk in the flour and allow it to cook for 1 minute. Gradually pour in the whole milk while whisking to avoid lumps. Bring to a gentle simmer, stirring until the sauce thickens, around 5-6 minutes.
Incorporate the Parmesan cheese and Old Bay seasoning, stirring until smooth.

Grease a 9×13 baking dish. Spread a thin layer of white sauce at the base; layer 3 noodles, half the seafood filling, dollops of cottage cheese, ⅓ of the white sauce, and a sprinkle of mozzarella. Repeat once more.
Finish with the last 3 noodles, the remaining sauce, and all the mozzarella on top.
Cover the dish with foil and bake for 30 minutes. Uncover and bake for an additional 15-20 minutes, then broil for 3-5 minutes until the cheese is golden.

Allow resting for 10-15 minutes for easier slicing. Garnish with fresh parsley before serving.

Pro Tips & Troubleshooting

For extra flavor, consider adding a squeeze of fresh lemon juice just before serving.
If the sauce thickens too much, add a splash more milk to adjust the consistency before layering.

Feeling adventurous? Swap the shrimp for scallops or mix in some crab meat for variations.
This recipe scales beautifully; you can easily double the ingredients for larger gatherings!

Storage & Make-Ahead Guide

This Seafood Lasagna can be stored in the fridge for up to 3 days or frozen for up to 2 months. When reheating, use an oven set to 350°F (175°C) for 25-30 minutes or microwave individual portions for about 2 minutes. After one testing, I noticed that freezing didn’t compromise the flavor, making it perfect for meal prep!

1 cup cottage cheese
1 Tbsp fresh parsley finely chopped
2 cups mozzarella cheese shredded

Instructions

Gather and prep all ingredients and set the oven to 375°F.

Cook the lasagna noodles in salted water until just tender. Drain and lay flat on parchment paper lightly drizzled with oil to prevent sticking.
In a large skillet, melt 1 Tbsp butter over medium heat. Sauté onion, celery, and garlic for 5-6 minutes, until softened. Stir in shrimp, imitation crab, spinach, lemon juice, and Cajun seasoning. Cook just until the shrimp turn pink and are cooked through. Remove from heat.

Slowly pour in the milk, whisking constantly. Bring to a gentle simmer and cook until thickened, about 5-6 minutes.
Stir in Parmesan and Old Bay seasoning. The sauce should be silky and pourable.

Grease a 9×13 baking dish. Spread a thin layer of white sauce on the bottom. Layer 3 noodles slightly overlapping, half of the seafood filling, dollops of cottage cheese mixture, ⅓ of the white sauce, and a sprinkle of mozzarella. Repeat the layers once more. Finish with the last 3 noodles, the remaining sauce, and the rest of the mozzarella.
Cover tightly with foil and bake for 30 minutes. Uncover and bake for another 15-20 minutes. Broil on high for 3-5 minutes, until the cheese is golden.
Let the seafood lasagna rest for 10-15 minutes before slicing. Garnish with any leftover fresh parsley and enjoy.
