Boil the Pasta
Cook manicotti shells in salted water until just al dente.
Drain and let cool slightly so they’re easier to handle without tearing.
Prepare the Filling
In a large bowl, combine ricotta, mozzarella, Parmesan, and egg.
Season with Italian herbs, salt, and pepper.
Optional: fold in spinach, mushrooms, or cooked meat for extra flavor.
Fill the Shells
Spoon or pipe the cheese mixture into each manicotti shell carefully.
Arrange stuffed shells in a greased baking dish.
Assemble & Bake
Spread a thin layer of marinara sauce on the bottom of the dish.
Place the filled manicotti evenly, then cover with remaining sauce.
Sprinkle with extra mozzarella cheese.
Cover with foil and bake at 350°F (175°C) for 25–30 minutes.
Remove foil and bake another 10 minutes, until cheese is bubbly and golden.
Garnish & Serve
Let the manicotti rest for a few minutes before serving.
Garnish with chopped basil or parsley and enjoy!
