Cook the pasta:
Boil salted water in a large pot and cook the bowtie pasta according to package directions until al dente. Drain and set aside.
Brown the beef:
In a large skillet, cook the ground beef over medium heat until browned. Drain excess grease.
Make the garlic roux:
Push beef to one side. Melt butter in the skillet, add minced garlic, and sauté for about 30 seconds until fragrant. Stir in flour to make a light roux.
Add liquids:
Gradually pour in the beef broth while stirring continuously to avoid lumps. Add heavy cream and mix until the sauce begins to thicken.
Add cheese and seasoning:
Stir in Parmesan, salt, pepper, Italian seasoning, and red pepper flakes. Adjust to taste.
Combine:
Add cooked pasta to the skillet and toss to coat evenly in the creamy Parmesan garlic sauce.
Serve:
Garnish with fresh parsley and a sprinkle of extra Parmesan. Serve warm and enjoy!
