  • 1 package of manicotti
  • 1 5 ounce can of white crabmeat drained and chopped, if needed
  • 1/2 pound shrimp cooked (if needed) and chopped
  • 1 egg slightly beaten.
  • 1 small onion finely chopped
  • 2 cups shredded mozzarella cheese
  • 1/4 cup mayo
  • 2 tablespoons milk
  • 1 tablespoon Old Bay seasoning
  • 1 cup ricotta cheese
  • 1/4 cup butter
  • 1 3/4 tablespoons cornstarch
  • 2 cloves garlic, minced
  • 3 cups milk
  • 6 cups shredded parmesan cheese
  • 2 teaspoons salt
  • 2 teaspoons pepper
  • 1 cup fresh parsley, chopped ---optional


  • In a large casserole pan (a 9 by 13 will make all but 2 of your manicotti noodles), lay out your manicotti noodles. Pour boiling water over them until they are covered. Let soak 30 minutes. Drain off and let the noodles cool.
  • Mix the seafood, egg, onion, mozzarella cheese, Old Bay seasoning, mayo, and the 2 tablespoons of milk together.
  • Stuff the seafood filling into the cooled manicotti. To make this easier, use a Ziplock bag with a corner cut off.
  • In a medium heavy saucepan, melt the butter on low/medium heat.
  • When the butter is melted add the cornstarch and whisk just until smooth.
  • Add the minced garlic and whisk gently for about 1 minute or until fragrant.
  • Slowly pour in the milk, whisking continuously. Heat until the sauce thickens up a bit. Do NOT boil.
  • Add the parmesan cheese, return the pan to the heat, and continue stirring until the cheese is melted and the sauce is smooth.
  • Add the salt & pepper. Taste and add additional salt & pepper, if needed.
  • Spread the ricotta over the stuffed manicotti and top with the sauce. NOTE: if you are making a 9 by 13 pan you most likely won't use about 1/2 cup of the sauce.
  • Put into 350 degree preheated oven and bake for 45 minutes or until hot and bubbly.
  • Remove from the oven, turn the oven to broil. Top with parsley and broil for about 5 minutes or until golden brown.
  • Let cool before serving. Serve with a squeeze of lemon and sprinkle of fresh parsley.
