Servings

Serves 8

Step 1: Cook the Lasagna Noodles

Bring a large pot of salted water to a boil.

Cook the noodles until al dente according to package instructions.

Drain and rinse with cool water.

Lay them flat on lightly oiled parchment paper to prevent sticking.

Step 2: Cook the Seafood

Heat butter and olive oil in a large skillet.

Add onion and cook until softened.

Stir in the garlic and cook for 30 seconds.

Add the shrimp and scallops.

Cook for 2–3 minutes until nearly done.

Fold in the crab meat gently to avoid breaking it apart.

Season with Italian seasoning, paprika, salt, black pepper, and parsley.

Remove from the heat and let cool slightly.

Step 3: Make the Creamy White Sauce

Melt the butter in a saucepan over medium heat.

Whisk in the flour and cook for 1–2 minutes.

Gradually add the milk while whisking continuously until smooth.

Stir in the heavy cream, garlic powder, onion powder, nutmeg, salt, and pepper.

Cook until the sauce thickens.

Remove from the heat and stir in the Parmesan cheese until melted and smooth.

Step 4: Prepare the Ricotta Mixture

In a bowl, combine:

  • Ricotta cheese
  • Egg
  • Parmesan cheese
  • Parsley
  • Italian seasoning

Mix until creamy and well combined.

Step 5: Assemble the Lasagna

Lightly grease a 9×13-inch baking dish.

Spread a thin layer of white sauce on the bottom.

Add a layer of lasagna noodles.

Spread one-third of the ricotta mixture over the noodles.

Top with one-third of the seafood mixture.

Pour over a layer of white sauce.

Sprinkle with mozzarella.

Repeat the layers until all the ingredients are used.

Finish with the remaining white sauce, mozzarella, and Parmesan.

Step 6: Bake

Preheat the oven to 375°F (190°C).

Cover the dish with aluminum foil.

Bake for 40 minutes.

Remove the foil.

Bake for another 15–20 minutes until the cheese is golden brown and bubbling.

Step 7: Rest Before Serving

Let the lasagna rest for 15 minutes before slicing.

This allows the layers to firm up and makes serving much easier.

Tips for the Best Seafood Lasagna

Don't Overcook the Seafood

The seafood will continue cooking in the oven, so keep it slightly undercooked during the skillet step.

Use Fresh Parmesan

Freshly grated Parmesan melts more smoothly and provides a richer flavor than pre-grated varieties.

Drain Seafood Well

Excess moisture from seafood can make the lasagna watery, so pat ingredients dry if needed.

Build Even Layers

Spread fillings evenly to ensure every slice holds together and includes all the flavors.

Rest Before Cutting

Allowing the lasagna to cool for about 15 minutes helps the layers set and makes serving cleaner.

Storage Instructions

Refrigerator

Store leftovers in an airtight container for up to 3 days.

Freezer

Wrap tightly and freeze for up to 2 months.

Thaw overnight in the refrigerator before reheating.

Reheating

Oven

Cover with foil and bake at 350°F (175°C) for 20–25 minutes, or until heated through.

Microwave

Heat individual portions for 2–4 minutes, checking halfway through to avoid overcooking the seafood.
