1. Start by bringing a large pot of salted water to a boil. Cook the bowtie pasta according to the package instructions until it reaches an al dente texture. Drain the pasta and set it aside, reserving a bit of the starchy cooking water for later.

2. In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute, just until fragrant. Be careful not to let the garlic burn, as that can create a bitter flavor.

3. Add the ground beef to the skillet and cook, breaking it up with a spoon as it browns. Once the beef is fully cooked through, drain any excess fat from the pan.

4. To the beef, stir in the heavy cream, beef broth, garlic powder, onion powder, salt, and black pepper. Bring the mixture to a gentle simmer and let it cook for 5-7 minutes, allowing the sauce to thicken slightly.

5. Reduce the heat to low, then add the grated Parmesan cheese and butter. Stir continuously until the cheese has melted and the sauce has a rich, creamy consistency.

6. Add the cooked bowtie pasta to the skillet and toss everything together, ensuring the pasta is evenly coated in the flavorful, creamy beef sauce. If the sauce seems too thick, you can add a splash of the reserved pasta cooking water to thin it out to your desired consistency.

7. Remove the skillet from the heat and let the Garlic Parmesan Bowtie Pasta with Creamy Beef rest for a couple of minutes. This allows the sauce to further thicken and adhere to the pasta. Finally, serve the dish hot, garnished with fresh chopped parsley if desired.
