Creating One-Pot Philly Cheesesteak Soup can be straightforward if you follow these simple steps:

1. Cook the Steak: In a large pot, heat olive oil over medium-high heat. Add the thinly sliced steak, seasoning with salt and pepper. Cook until browned, about 3-5 minutes. Remove and set aside.

2. Sauté Vegetables: In the same pot, add the diced onion and bell peppers. Sauté until softened, approximately 5 minutes. Add minced garlic and cook for another minute until fragrant.

3. Add Broth and Seasoning: Pour in the beef broth, Worcestershire sauce, and Italian seasoning. Bring to a simmer and let it cook for 5 minutes.

4. Stir in the Cream: Reduce the heat to low and stir in the heavy cream. Allow it to simmer gently until heated through, about 5 minutes.

5. Return Steak to Pot: Add the cooked steak back into the pot. Stir to combine, and let it cook for another few minutes to heat the steak through.

6. Melt the Cheese: Gradually stir in the shredded provolone cheese until melted and creamy. Adjust the seasoning with salt and pepper as needed.

7. Serve: Ladle the soup into bowls and garnish with fresh parsley if desired.

These simple steps will guide you in creating this incredible soup effortlessly.
