Ingredients

Instructions

  1. Step 1: Preheat your oven to 375°F. Heat 2 tbsp olive oil in a large oven-safe skillet over medium heat. Add 1 lb Italian sausage and cook for 5-6 minutes, breaking it up with a spoon until browned and cooked through.
  2. Step 2: Add 1 medium diced yellow onion and 4 minced garlic cloves to the skillet with the sausage. Sauté for 4-5 minutes until the onion is translucent and the garlic is fragrant.
  3. Step 3: Stir in 28 oz crushed tomatoes, 2 tbsp tomato paste, 1 tsp dried oregano, 1 tsp dried basil, 1 tsp salt, and 1/2 tsp black pepper. Mix well and bring to a simmer.
  4. Step 4: Add 12 oz uncooked ziti pasta and 3 cups water to the skillet. Stir to combine, then cover and simmer on medium-low heat for 12 minutes, stirring occasionally.
  5. Step 5: Fold in 4 cups chopped fresh spinach and half of the 2 cups shredded mozzarella cheese. Stir until the spinach wilts and the cheese starts melting.
  6. Step 6: Sprinkle the remaining 1 cup mozzarella and 1/2 cup grated Parmesan cheese evenly over the top. Transfer the skillet to the preheated oven and bake uncovered for 15 minutes until the cheese is bubbly and golden on the edges.
  7. Step 7: Remove from oven and let rest for 5 minutes before serving to allow the sauce to thicken and flavors to meld.
