Description

A luxurious and sophisticated reimagining of a classic Italian favorite.

Layered with a zesty garlic-herb ricotta, it’s a restaurant-quality masterpiece perfect for any special occasion.


Ingredients

Scale

The Seafood & Pasta

  • 1 lb lasagna noodles, cooked
  • 1 lb cooked shrimp, chopped
  • 1 lb cooked crabmeat

The Parmesan Béchamel

  • 4 tbsp butter
  • 1/4 cup + 1 tbsp flour
  • 3 cups milk
  • 1/2 cup grated parmesan cheese
  • 1/2 tbsp salt, 1/4 tbsp ground white pepper

The Garlic Herb Cheese Layer

  • 15 oz ricotta cheese
  • 1 egg
  • 2 tsp minced garlic
  • 2 cups mozzarella cheese, grated
  • 1/2 cup chopped parsley

The Topping

  • 1/2 cup mozzarella (reserved), 1/2 cup parmesan (reserved)

Instructions

Sauce: Melt butter and whisk in flour. Gradually add milk, whisking until thickened. Stir in parmesan, salt, and white pepper.

Cheese: Mix ricotta, egg, garlic, 2 cups mozzarella, and parsley.

Assemble: Grease 9×13 pan. Spread 1 cup sauce. Layer 3 noodles, 1/3 ricotta mix, and 1/3 seafood. Repeat twice.

Bake: Top with remaining sauce and reserved cheeses. Bake covered at 350°F for 30 mins; uncover and bake 10 mins more until golden.

Rest: Let rest for 20 minutes before slicing to set the layers.

Notes

White Pepper Secret: Keeps the béchamel pristine and professional without black specks.

Resting Rule: The 20-minute rest is essential; without it, the creamy layers will slide apart upon slicing.

Seafood Prep: Thoroughly drain shrimp and crab to prevent a ‘soupy’ lasagna.
