01 - Bring a large pot of salted water to a boil. Cook tortellini according to package directions, adding broccoli florets for the final 2 minutes. Drain and set aside.
02 - Pat chicken pieces dry with paper towels and season evenly with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add seasoned chicken and cook for 5 to 6 minutes, turning occasionally, until golden and fully cooked through. Remove chicken to a plate and cover to keep warm.
04 - In the same skillet over medium heat, melt the unsalted butter. Add the minced garlic and sauté for about 1 minute, just until fragrant.
05 - Lower heat to medium. Pour in heavy cream, stirring to deglaze pan. Bring to a gentle simmer. Add Parmesan cheese and stir until fully melted and sauce starts to thicken, about 2 to 3 minutes.
06 - Return cooked tortellini, broccoli, and chicken to the skillet. Gently toss to coat all ingredients in the sauce. Stir in crushed red pepper flakes if desired.
07 - Taste and adjust seasoning with additional salt and pepper if needed. Serve hot, garnished with extra Parmesan cheese and fresh parsley.
