01 - Bring a large pot of salted water to a boil. Cook tortellini according to package instructions, adding broccoli florets in the final 2 minutes. Drain both and set aside.
02 - Pat chicken pieces dry and season all sides with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken and cook, turning occasionally, until golden and completely cooked through, about 5 to 6 minutes. Remove chicken from skillet and set aside.
04 - Add butter to the same skillet and melt over medium heat. Add minced garlic and sauté for 1 minute until aromatic.
05 - Reduce heat to medium. Pour in heavy cream and stir to combine. Bring to a gentle simmer, then scatter in Parmesan cheese. Stir until cheese is fully melted and the sauce thickens, about 2 to 3 minutes.
06 - Return cooked tortellini, broccoli, and chicken to the skillet. Gently toss to coat everything in the sauce. Sprinkle in crushed red pepper flakes if desired.
07 - Taste and adjust seasoning with additional salt and pepper as needed. Serve hot, garnished with extra Parmesan cheese and chopped parsley if preferred.
