1. Bring a large pot of salted water to a boil. Cook bowtie pasta until al dente. Drain and set aside.

2. In a large skillet over medium-high heat, add olive oil or butter. Add ground beef and cook until browned and fully cooked. Season with salt and pepper. Remove beef and set aside.

3. In the same skillet, reduce heat to medium. Add minced garlic and sauté for 30 seconds to 1 minute until fragrant.

4. Pour in beef broth and deglaze the skillet, scraping any brown bits from the bottom. Let simmer for 2-3 minutes.

5. Stir in heavy cream and bring to a gentle simmer. Add Parmesan cheese and stir until melted and smooth. Taste and adjust seasoning.

6. Return cooked beef to the skillet. Add drained pasta and toss gently to coat everything in the creamy sauce.

7. Garnish with chopped parsley and extra Parmesan if desired. Serve immediately while hot.
