Instructions
Preheat oven to 350°F.
Boil pasta: Bring a large pot of lightly salted water to a boil. Add 12 ounces jumbo pasta shells and cook for only 3-4 minutes and then drain. You want to start the cooking process, but you need them firm enough to stuff. They will continue cooking in the oven.
Mix cheeses: In a large bowl, mix 2 eggs, 16 ounces ricotta cheese, 8 ounces mascarpone cheese, half the 1 pound shredded mozzarella cheese, half the 8 ounces grated Parmesan cheese, 1 tablespoon dried Italian seasoning, 8 fresh basil leaves, 2 cloves garlic, 1/2 teaspoon salt and 1/4 teaspoon red pepper flakes until well combined.
Fill pasta shells: Add ricotta mixture to a resealable plastic bag or a piping bag. Snip the corner off. Fill each par cooked shell with the cheese filling. Place stuffed shells in a 9x13 inch baking dish.
Add remaining ingredients: Cover shells with 56 ounces pasta sauce and then top with remaining shredded cheese. Cover with foil.
Bake: Cook covered stuffed shells in preheated oven for 45 minutes. Remove foil and continue cooking for another 5-15 minutes until edges are bubbly and cheese is melted. Best results if you let stand for 15 minutes before serving.
Notes
Make ahead and freezer directions: Prepare recipe all the way up until you cover casserole dish with foil. At this point the shells can be refrigerated for one day before baking or can be frozen. If frozen, allow them to fully thaw in refrigerator before baking. Cook time may need to be increased if shells are cold.
