This manicotti is filled with 3 kinds of cheese and baked to absolute perfection! It's comfort food at its finest that everyone will go crazy over! It's definitely sure to please a large crowd!
Preheat oven to 350 degrees. Cook the manicotti according to package directions and rinse in cold water.
In a medium-sized bowl combine ricotta, one cup of mozzarella cheese, parmesan, spinach, Italian seasoning, and egg.
Stuff the shells with the cheese mixture. I find that using a piping bag works the best.
In a 9x13 inch, pan add 1 cup of marinara sauce to the bottom. Line the manicotti in an even layer. Cover with remaining sauce and cheese. Bake for 25-30 minutes or until cheese is melted and bubbly.
