Follow these steps to create your Garlic Steak Tortellini:

1. Cook Tortellini: Bring a pot of salted water to a boil. Add the tortellini and cook according to package directions. Drain and set aside.
2. Sear the Steak: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Season the steak strips with salt and pepper. Add the steak to the skillet and sear until browned, about 3-4 minutes. Remove the steak from the pan and set it aside.
3. Sauté Garlic: In the same skillet, add the remaining tablespoon of olive oil. Lower the heat slightly and add the minced garlic. Sauté for about 30 seconds, or until fragrant, being careful not to burn it.
4. Add Broth and Cream: Pour in the beef broth and bring to a simmer. Add the heavy cream and stir well to combine.
5. Mix in Seasonings: Add the Italian seasoning and red pepper flakes (if using). Stir to incorporate.
6. Combine Ingredients: Return the cooked steak to the skillet, and add the cooked tortellini. Toss to coat everything in the sauce evenly.
7. Add Cheese: Sprinkle the grated Parmesan cheese over the tortellini and stir until melted and smooth.
8. Garnish: Remove from heat and sprinkle with fresh parsley before serving.
