01 - Bring a large pot of salted water to a boil. Cook the tortellini according to package instructions, adding the broccoli florets during the final 2 minutes of cooking. Drain and set aside.
02 - While the pasta cooks, season chicken pieces with salt and black pepper.
03 - In a large skillet, heat olive oil over medium-high heat. Add chicken and cook until golden and cooked through, about 5 to 6 minutes. Transfer chicken to a plate and set aside.
04 - In the same skillet, add butter. Once melted, add minced garlic and sauté for 1 minute until fragrant.
05 - Reduce heat to medium. Pour in heavy cream, stirring to incorporate. Bring to a gentle simmer. Add Parmesan cheese and stir until melted and sauce is thickened, approximately 2 to 3 minutes.
06 - Return cooked tortellini, broccoli, and chicken to the skillet. Toss to coat evenly with the creamy sauce. Stir in crushed red pepper flakes if desired.
07 - Taste and adjust with additional salt and black pepper as needed.
08 - Serve hot, garnished with additional Parmesan and fresh parsley if preferred.
