Ingredients
Method
- Bring large pot of salted water to boil. Cook rigatoni until al dente, about 2 minutes less than package directions. Reserve 1 cup pasta water before draining.
- Heat olive oil in large skillet over medium heat. Add diced onion and sauté 3-4 minutes until softened. Stir in minced garlic and cook 1 minute until fragrant.
- Add ground beef to skillet, breaking apart with spatula. Cook 6-8 minutes until browned completely. Drain excess grease if needed.
- Stir in tomato paste, Italian seasoning, red pepper flakes (if using), salt, and pepper. Cook 2-3 minutes to deepen flavors.
- Pour in beef broth and heavy cream, stirring to combine. Simmer 5-7 minutes until sauce thickens slightly.
- Remove from heat. Gradually stir in Parmesan cheese until melted, then add mozzarella and stir until smooth and creamy.
- Add cooked rigatoni to skillet and toss until well coated. Use reserved pasta water to adjust consistency if needed.
- Serve immediately garnished with fresh parsley or basil and extra Parmesan cheese.
Notes
For best results, use freshly grated Parmesan cheese rather than pre-shredded. Add cheese off heat to prevent graininess. Sauce thickens when refrigerated—add milk or broth when reheating.
