Heat olive oil in a large skillet over medium-high heat. Add ground beef and cook until browned, breaking it apart with a spoon. Drain excess fat if needed.

Stir in onion and garlic, cooking for 2–3 minutes until fragrant and softened.

Add Worcestershire sauce, Italian seasoning, and smoked paprika. Stir well and cook for 1 minute.

Melt butter into the mixture, then pour in beef broth. Scrape the bottom of the skillet for extra flavor and simmer for 3–4 minutes.

Stir in half and half and Parmesan cheese until melted and creamy. Season with salt, black pepper, and red pepper flakes (if using).

Meanwhile, cook bowtie pasta in salted water according to package directions until al dente. Drain, reserving ½ cup of pasta water.

Add the pasta into the creamy beef sauce. Toss gently to coat. If needed, use reserved pasta water to thin the sauce.

Garnish with parsley and serve hot.
