Cook the Pasta: Bring a large pot of salted water to a boil. Cook the bowtie pasta according to package directions until al dente. Drain and reserve ½ cup of pasta water. Set pasta aside.
Brown the Beef: In a large skillet over medium heat, cook the ground beef until fully browned, breaking it apart as it cooks. Drain excess fat.
Prepare the Garlic Butter Sauce: Add the butter and minced garlic to the skillet with the beef. Cook for about 1 minute, stirring, until the garlic is fragrant.
Make the Creamy Sauce: Pour in the heavy cream and stir to combine. Add salt, black pepper, Italian seasoning, and red pepper flakes (if using). Stir to incorporate.
Melt the Cheese: Gradually stir in the shredded cheddar and Parmesan cheese until melted and the sauce is smooth and creamy.
Combine with Pasta: Add the cooked pasta to the skillet, tossing to coat in the sauce. Add reserved pasta water a little at a time until the desired sauce consistency is reached.
Serve: Sprinkle with fresh chopped parsley and serve warm.
Notes
For extra creaminess, add more cheese or a splash of milk.
Substitute ground turkey or chicken for a lighter option.
Add vegetables like spinach or mushrooms for extra nutrition.
