01 - Prepare the cheese tortellini according to the instructions on the package. Once fully cooked, drain the water thoroughly and set the pasta aside.
02 - Generously season the bite-sized sirloin steak pieces with salt and freshly ground black pepper on all sides.
03 - Heat olive oil in a large skillet over medium-high heat. Add the seasoned steak pieces and sear for 2–3 minutes per side until browned and cooked to your preferred doneness. Remove the steak from the skillet and set aside.
04 - Reduce the skillet heat to medium. Add the unsalted butter, then sauté the chopped shallots and minced garlic until fragrant, approximately 1 minute.
05 - Pour the heavy cream into the skillet, stirring constantly to combine with the aromatics. Bring the mixture to a gentle simmer and let it cook for 2–3 minutes until the sauce thickens slightly.
06 - Stir in the grated Parmesan cheese until it is fully melted and the sauce is smooth.
07 - Return the cooked tortellini and seared steak to the skillet. Toss everything gently to coat evenly in the garlic cream sauce and heat through for 1–2 minutes. Sprinkle with chopped fresh parsley before serving.
