01 - Cook the tortellini according to package instructions. Drain and set aside.
02 - Season the steak pieces generously with salt and pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add steak pieces and sear for 2–3 minutes per side, or until browned and cooked to desired doneness. Remove steak and set aside.
04 - In the same skillet, reduce heat to medium. Add butter, then sauté shallots and garlic until fragrant, about 1 minute.
05 - Pour in heavy cream, stirring to combine. Bring to a simmer and cook for 2–3 minutes, allowing the sauce to thicken slightly.
06 - Stir in Parmesan cheese until melted and smooth.
07 - Return tortellini and steak to the skillet. Toss gently to coat in the sauce and heat through, 1–2 minutes. Sprinkle with chopped parsley before serving.
