Creating the One-Pot Philly Cheesesteak Soup is straightforward, and the instructions are easy to follow. Here’s how to do it:

1. Brown the Beef: In a large pot, heat the olive oil over medium-high heat. Add the sliced beef sirloin. Season with salt and pepper, then cook until browned. Remove the beef from the pot and set it aside.
2. Sauté Onions and Peppers: In the same pot, add the diced onions and bell pepper. Sauté until they are soft, about 5–7 minutes. Stir in the minced garlic and cook for an additional minute.
3. Add Broth and Seasonings: Return the beef to the pot. Add the beef broth, heavy cream, Worcestershire sauce, and Italian seasoning. Bring to a simmer.
4. Simmer the Soup: Reduce the heat to medium-low and let the soup simmer for about 20 minutes. Stir occasionally to prevent sticking and ensure even cooking.
5. Incorporate Cheese: Stir in the shredded provolone cheese until melted and creamy. Adjust seasoning with salt and pepper if needed.
6. Garnish and Serve: Remove from heat and ladle the soup into bowls. Garnish with fresh parsley before serving.

Following these simple steps will help you whip up a hearty pot of this delightful soup with ease.
