Begin by bringing a large pot of salted water to a rolling boil. Add the bowtie pasta and cook according to the package instructions, usually about 10-12 minutes, until al dente. Stir occasionally, then drain and set aside.

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the ground beef and cook until browned, about 5-7 minutes, stirring occasionally.

Add 4 minced garlic cloves to the skillet and sauté for about 1 minute until fragrant, being careful not to burn the garlic.

Pour in 2 tablespoons of Worcestershire sauce and 1 cup of heavy cream. Stir well and let simmer for 2-3 minutes.

Gradually sprinkle in 1 cup of freshly grated Parmesan cheese while stirring constantly until melted and incorporated, about 2 minutes.

Add the drained bowtie pasta to the skillet and toss to coat. Adjust sauce consistency if needed, then garnish with freshly chopped parsley before serving warm.
