Bring a large pot of salted water to a boil over high heat and cook the manicotti shells according to the package instructions. Cook until they are al dente (firm but not too soft), about 6 to 7 minutes. Avoid overcooking the pasta because if it’s too soft, the tubes can be more difficult to fill.
12 manicotti pasta shells, from 8 ounce package
Drain the manicotti and rinse with cold water to prevent them from sticking together. I like to arrange them individually on a clean lint-free dish towel to drain completely. Set aside.
Meanwhile, in a medium bowl, mix together ricotta cheese, 1 ½ cups mozzarella, Parmesan, egg, parsley, oregano, garlic powder, salt, and black pepper. Stir until well combined.
2 cups ricotta cheese, 2 ½ cups shredded mozzarella cheese, divided, ½ cup grated Parmesan cheese, 1 large egg, 1 teaspoon dried parsley, 1 teaspoon dried oregano, ½ teaspoon garlic powder, ½ teaspoon kosher salt, ¼ teaspoon coarse ground black pepper
Preheat oven to 350°F. Spread about ½ cup of sauce on the bottom of a 9 x 13-inch baking dish.
2 cups marinara sauce
Fill a piping bag (or use a small spoon, or a zip-top bag with the corner cut off) with the ricotta mixture and carefully stuff each manicotti shell (see note #2). Be gentle to avoid tearing the pasta. Arrange the stuffed manicotti shells in a single layer in the baking dish.
Pour the remaining 1 ½ cups marinara sauce over the top of the manicotti. Sprinkle the remaining 1 cup shredded mozzarella over the manicotti.
Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 15 to 20 minutes, or until the cheese is melted.
Let the manicotti cool for five to ten minutes before serving. Garnish with fresh basil or parsley if desired. Carefully scoop out 2 stuffed manicotti per serving.

Notes
Manicotti shells: The dry pasta is usually sold in an 8 ounce box which contains 2 plastic trays holding 6 to 8 shells each. The brand I usually buy has 12 pasta shells. If yours has more, I'd advise cooking all of them. You can put less filling in each or simply have a few backup shells in case one tears while filling it.
Filling tip: To fill the piping bag, set it upright in a large drinking glass. Fold the edges of the bap over the edge of the glass to hold the bag open. Spoon about half of the filling into the bag at a time. Lightly twist the top of the bag and lift the bag out of the glass. Snip about a half inch off the tip of the bag to fill the manicotti.
Make ahead: Prepare the manicotti as directed but don’t bake. Cover with foil and refrigerate up to 24 hours in advance. Remove manicotti from refrigerator about a half hour before baking. Bake as directed. Unbaked manicotti can be frozen for up to 3 months. Thaw overnight in the refrigerator before baking.
Add meat: Use a meaty spaghetti sauce instead of marinara sauce.
