01 - Bring a large pot of salted water to a boil. Add the tortellini and cook according to package instructions, adding broccoli florets during the last 2 minutes of cooking. Drain thoroughly and set aside.
02 - Pat chicken pieces dry and season evenly with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add the chicken and sauté until golden brown and fully cooked, about 5 to 6 minutes. Remove cooked chicken from the skillet and set aside.
04 - In the same skillet, melt the butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant, stirring constantly to avoid browning.
05 - Lower the heat to medium and pour in the heavy cream. Stir to combine and bring to a gentle simmer. Add Parmesan cheese and whisk until the cheese is fully melted and sauce has thickened, about 2 to 3 minutes.
06 - Return the cooked tortellini, broccoli, and chicken to the skillet. Gently toss to coat all ingredients with the cream sauce. Stir in crushed red pepper flakes if desired.
07 - Taste and adjust seasoning with additional salt and black pepper as needed. Serve immediately, garnished with extra Parmesan and fresh parsley if preferred.
