01 - Prepare the tortellini according to package instructions. Drain well and set aside.
02 - Generously season the cut steak pieces with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add the steak pieces and sear for 2–3 minutes per side until browned and cooked to desired doneness. Remove the steak from the skillet and set aside.
04 - Reduce the skillet heat to medium. Add the butter, shallots, and garlic. Sauté for about 1 minute until fragrant.
05 - Pour in the heavy cream and stir to combine. Bring the mixture to a simmer and cook for 2–3 minutes until the sauce thickens slightly.
06 - Stir in the grated Parmesan cheese until fully melted and the sauce is smooth.
07 - Return the cooked tortellini and seared steak to the skillet. Toss gently to coat everything in the sauce and heat through for 1–2 minutes. Sprinkle with fresh parsley before serving.
