Step 1

Preheat oven to 350 F.

Step 2

Bring a large pot of salted water to a boil over medium-high heat. Add Manicotti shells and cook until al dente, about 8-10 minutes (or according to package directions). Rinse the noodles under cold water to stop the cooking process and set aside in the pot.

Step 3

In a medium mixing bowl, combine ricotta cheese, 1 cup mozzarella, Parmesan, beaten egg, and parsley. Stir well to combine together. Set aside.

Step 4

In a large baking sheet, assemble the Manicotti by dividing the cheese mixture evenly and fill it inside manicotti shells until full. You can use a large piping bag for easy stuffing.

Step 5

In a 10x15-inch casserole dish, spread 1 cup marinara sauce evenly on the bottom. Arrange the stuffed Manicotti shells evenly on top.

Step 6

Spread the remaining marinara sauce over and sprinkle the remaining 1 1/2 cups mozzarella cheese on top.

Step 7

Bake (covered with foil) for 30-35 minutes. Remove the foil and bake uncovered for another 5-10 minutes or until the melted cheese turns golden brown and bubbly. Optionally, turn the oven to broil and broil on high for 1-2 minutes to get the crispy and brown cheesy crust.

Step 8

Let the Manicotti rest and cool for 10 minutes before serving.

Step 9

Serve with grated Parmesan and fresh parsley on top, if desired.
