Begin by bringing a large pot of salted water to a rolling boil over high heat. Add the bowtie pasta and cook it until al dente for about 10-12 minutes. Drain the pasta in a colander and set aside without rinsing.

In a large skillet, heat 2 tablespoons of olive oil over medium heat until shimmering. Add the finely diced onion, sauté until golden and translucent (about 5 minutes). Stir in minced garlic and cook for an additional 30 seconds until fragrant.

Introduce the ground beef to the skillet, breaking it apart with a wooden spoon. Cook for about 6-8 minutes until browned and fully cooked. Drain excess fat if necessary.

Pour in 1 cup of beef broth, scraping up any browned bits from the bottom of the skillet with a wooden spoon. Season with red pepper flakes, salt, and black pepper. Let it simmer gently for about 3-5 minutes.

Add the drained bowtie pasta into the skillet, tossing it well with the beef and sauce until evenly coated. Drizzle in extra olive oil if desired.

Plate your Garlic Butter Bowtie Pasta, adding a generous sprinkle of grated Parmesan cheese and fresh parsley. Serve hot and enjoy!
