01 - Bring a large pot of salted water to a boil. Add rigatoni and cook according to package directions until al dente. Drain and set aside.
02 - Warm the olive oil in a large skillet over medium-high heat. Add finely chopped onion and minced garlic. Cook for 3–4 minutes until the onion is soft and translucent.
03 - Add diced beef to the skillet. Sauté, stirring occasionally, until browned on all sides and fully cooked through.
04 - Sprinkle the beef with paprika, salt, and black pepper. Stir well. Pour in beef broth and heavy cream, mixing thoroughly. Bring to a simmer, then reduce heat to medium-low.
05 - Let the sauce simmer for 10 minutes, stirring occasionally, until it thickens slightly.
06 - Add the cooked rigatoni to the skillet. Stir well to coat the pasta evenly with the creamy sauce.
07 - Remove the skillet from heat. Sprinkle in shredded cheddar cheese, stirring until melted and the sauce is smooth.
08 - Plate the pasta and garnish with freshly chopped parsley. Serve immediately while warm.
