01 - Boil a large pot of salted water. Cook tortellini according to package directions. Add broccoli florets to the pot for the last 2 minutes. Drain both and reserve.
02 - Season chicken pieces generously with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken and cook 5–6 minutes until golden and fully cooked. Transfer chicken to a plate and set aside.
04 - Melt unsalted butter in the same skillet. Add minced garlic and sauté 1 minute, stirring constantly, until fragrant.
05 - Reduce heat to medium. Pour in heavy cream and stir to combine. Bring to a gentle simmer, then fold in Parmesan cheese. Stir until cheese melts and sauce thickens, about 2–3 minutes.
06 - Add cooked tortellini, broccoli, and sautéed chicken to the skillet. Toss to coat all ingredients with the creamy sauce. Mix in crushed red pepper flakes if desired.
07 - Taste and adjust seasoning with additional salt and pepper as preferred.
08 - Serve hot, garnished with extra Parmesan and freshly chopped parsley if desired.
