01 - Generously coat the steak pieces with salt and freshly ground black pepper on all sides.
02 - Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Arrange the steak pieces in a single layer and sear for 2–3 minutes per side until deeply browned and cooked to your preferred doneness. Remove the steak from the skillet and set aside.
03 - In the same skillet, add the remaining olive oil and butter over medium heat. Once the butter has melted, add the minced garlic and sauté for 1 minute until fragrant and lightly golden.
04 - Pour in the heavy cream and bring to a gentle simmer. Stir in the grated Parmesan cheese and continue stirring until the sauce is smooth and slightly thickened, about 2 minutes.
05 - While the sauce simmers, cook the tortellini in a large pot of salted boiling water according to the package instructions. Drain well using a colander.
06 - Add the drained tortellini to the garlic cream sauce, tossing to coat evenly. Return the seared steak pieces to the skillet and gently fold everything together. Cook for 1–2 minutes over low heat, allowing the flavors to meld.
07 - Garnish with fresh chopped parsley and additional Parmesan if desired. Serve immediately while hot.
