01 - Bring a large pot of salted water to a boil. Add farfalle pasta and cook until al dente according to package instructions. Reserve 1/2 cup of pasta water, then drain the pasta thoroughly.
02 - Heat a large skillet over medium-high. Add ground beef, season with salt, black pepper, and onion powder. Cook, stirring to crumble, until beef is thoroughly browned. Drain any excess fat if needed.
03 - Stir in minced garlic and Italian seasoning. Sauté with the beef until the garlic is fragrant, about 1 minute.
04 - Reduce skillet heat to low. Pour in Alfredo sauce, heavy cream, and grated Parmesan cheese. Mix until sauce is smooth and well combined.
05 - Add cooked pasta to the skillet. Toss thoroughly to coat the pasta evenly with the sauce, adding reserved pasta water as needed to achieve desired consistency.
06 - Garnish the dish with chopped fresh parsley and a sprinkle of red pepper flakes, if using. Serve immediately while hot.
