Cook manicotti per package instructions, then lay on parchment paper to dry and cool.
While manicotti noodles cool, preheat oven to 350 degrees F.
In a large bowl, mix together ricotta, mozzarella, parmesan, eggs, parsley, salt, and pepper.
Using a spoon (and your fingers!) gently feed the cheese mix into the cooled manicotti noodles. Tip: pack one end until full, then do the same with the other end.
In a 9×11 baking dish, spread a thin layer of Bertolli Riserva sauce along the bottom. Place filled manicotti on top of sauce in a single layer. Cover top of manicotti with renaming Bertolli Riserva sauce.
Cover dish with foil and bake for 40 minutes. Remove foil and sprinkle mozzarella cheese on top (optional). Bake for another 5-10 minutes or until cheese has melted.
Serve immediately with more parsley on top for garnish.
