Cook the bowtie pasta according to the package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the cubed chicken and season with salt and pepper. Cook until the chicken is browned and cooked through, about 5-7 minutes.
Add the diced onion and minced garlic to the skillet. Sauté for 2-3 minutes, until the onion is translucent.
Pour in the chicken broth and bring to a simmer. Stir in the heavy cream and Italian seasoning, then reduce the heat to low.
Add the cooked bowtie pasta and grated Parmesan cheese to the skillet. Stir until well combined and heated through, about 2-3 minutes.
Taste and adjust seasoning with salt and pepper as needed. Remove from heat and garnish with fresh parsley before serving.
Notes
For a lighter version, you can use half-and-half instead of heavy cream.
