Creating Garlic Steak Tortellini is straightforward. Follow these steps to ensure your dish turns out perfectly:

1. Cook the Tortellini: In a large pot, bring salted water to a boil. Add the cheese tortellini and cook according to package instructions. Drain and set aside.
2. Prepare the Steak: While the tortellini cooks, season the sirloin steak with salt and pepper. Cut it into strips.
3. Sear the Steak: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the steak strips and sear for about 3-4 minutes until browned and cooked to your liking. Remove from the skillet and set aside.
4. Sauté the Garlic: In the same skillet, add the remaining tablespoon of olive oil. Add minced garlic and sauté for about 30 seconds until fragrant. Be careful not to burn the garlic.
5. Make the Sauce: Pour in the heavy cream and simmer for 2-3 minutes, allowing it to thicken slightly.
6. Add Cheese: Stir in the grated Parmesan cheese until melted and smooth.
7. Combine Ingredients: Add the cooked tortellini and the seared steak back into the skillet. Toss gently to coat everything in the sauce.
8. Season: Taste and adjust seasoning with salt and pepper as needed.
9. Garnish: Remove from heat and sprinkle fresh parsley on top before serving.

These steps will guide you in creating a wonderful Garlic Steak Tortellini that is creamy, flavorful, and utterly delicious.
