Turkey & Artichoke Stuffed Pasta Shells + Homemade Arrabbiatta Sauce

I got this recipe out of my Everyday Italian cookbook, but you can find it here.
These were really good, but I also think they would be perfect with Chicken too! These would be great to make for a dinner party as well because they make so much, and you only need about 2-3 to get you full! I halved this recipe below to make 4 servings.

Ingredients:
~1 (12-ounce) box jumbo pasta shells (recommended: Barilla)
~3 tablespoons extra-virgin olive oil
~1/2 large yellow onion, chopped (about 1 cup)
~3 cloves garlic, chopped
~1 pound ground turkey
~1/2 teaspoon kosher salt, plus 1/2 teaspoon
~1/4 teaspoon freshly ground black pepper, plus 1/4 teaspoon
~1 (8 to 10-ounce) package frozen artichokes, thawed and coarsely chopped
~1 (15-ounce) container part skim ricotta cheese
~3/4 cup grated Parmesan
~2 eggs, lightly beaten
~1/4 cup chopped fresh basil leaves
~2 tablespoons chopped fresh flat-leaf parsley

Directions
5 cups Arrabbiata Sauce, recipe follows
1 1/2 cups grated mozzarella (about 5 ounces)

Bring a large pot of salted water to a boil over high heat. Add the pasta and partially cook until tender but still very firm to the bite, stirring occasionally, about 4 to 5 minutes. Drain pasta.

Meanwhile, in a large heavy skillet, heat the olive oil over medium-high heat. Add the onions and the garlic and cook until the onions are soft and starting to brown, about 3 minutes. Add the ground turkey, 1/2 teaspoon salt, and 1/4 teaspoon black pepper and continue to cook, stirring occasionally, until the meat is slightly golden and cooked through. Add the artichoke hearts and stir to combine. Remove from heat and let cool.

In a large bowl combine the cooled turkey mixture with the ricotta cheese, Parmesan cheese, eggs, basil, parsley, and the remaining salt and pepper. Stir to combine.

To stuff the shells, cover the bottom of a 9 by 13 by 2-inch baking dish with 1 cup of Arrabbiata sauce. Take a shell in the palm of your hand and stuff it with a large spoonful of turkey mixture, about 2 tablespoons. Place the stuffed shell in the baking dish. Continue filling the shells until the baking dish is full, about 24 shells. Drizzle the remaining Arrabbiata Sauce over the shells, top with the grated mozzarella. If freezing, cover tightly with plastic wrap and place in the freezer for 1 day and up to 1 month.

To bake, preheat the oven to 400 degrees F. Bake until the shells are warmed through and the cheese is beginning to brown, about 60 minutes (20 minutes if shells are unfrozen.)

Arrabbiata Sauce:
~2 tablespoons extra-virgin olive oil
~6 ounces sliced pancetta, coarsely chopped
~2 teaspoons crushed red pepper flakes
~2 garlic cloves, minced
~5 cups jarred or fresh marinara sauce

Heat the olive oil in a large soup pot over medium heat. Add the pancetta and saute until golden brown, about 5 minutes. Add the garlic and saute until tender, about 1 minute. Add the marinara sauce and red pepper flakes and bring to a simmer. Remove from heat and let cool until ready to use.

Yield: approximately 6 cups
