Ingredients

  • 16 oz dried ziti pasta or substitute penne, rigatoni, etc.
  • 1 tablespoon olive oil
  • 1 lb ground Italian sausage hot or mild
  • 4 cloves garlic minced
  • 32 oz marinara sauce Rao’s recommended
  • 1/2 teaspoon red pepper flakes
  • 3 cups shredded mozzarella cheese divided
  • 1/2 cup Pecorino Romano cheese divided
  • Minced fresh parsley for garnish

Instructions

Preheat Oven & Prep Dish:

  • Preheat oven to 350°F (175°C). Butter a 9x13-inch baking dish and set aside.

Cook Pasta:

  • Bring a large pot of salted water to a boil.
  • Cook the ziti about 1 minute less than package directions for al dente.
  • Drain and set aside, stirring occasionally to prevent sticking.

Cook Sausage:

  • Heat a large skillet over medium-high heat.
  • Add olive oil and sausage. Cook, breaking it up with a spoon, until browned and cooked through (about 5–6 minutes).
  • Drain any excess fat and return sausage to the skillet.

Add Garlic & Sauce:

  • Stir in the minced garlic.
  • Pour in marinara sauce and red pepper flakes. Mix well.
  • Simmer for about 10 minutes until sauce is slightly thickened.

Combine with Pasta:

  • Remove skillet from heat and stir in the cooked pasta until evenly coated.

Assemble the Ziti:

  • Add half of the pasta mixture to the prepared baking dish.
  • Sprinkle with half of the mozzarella and Pecorino Romano cheeses.
  • Add the remaining pasta and top with the remaining cheeses.

Bake:

  • Bake uncovered for 20 minutes or until the cheese is melted and bubbly.

Cool & Serve:

  • Remove from oven and let rest for 5–10 minutes.
  • Garnish with fresh parsley and serve warm.

Notes

Serves 6, but portions can be adjusted based on appetite.
Penne or rigatoni can be used in place of ziti.
Pre-shredded mozzarella is convenient, but grating Pecorino Romano fresh gives the best flavor.
