Making One Pot Fully Cheesesteak Soup is simple if you follow these detailed steps:

1. Sauté the Beef: In a large pot, heat olive oil over medium-high heat. Add the sliced beef and sauté until browned. Remove the beef and set aside.

1. Cook the Vegetables: In the same pot, add the diced onion and bell pepper. Sauté until softened, about 5-7 minutes. Add minced garlic and cook for another minute.

1. Add Liquid Ingredients: Pour in the beef broth and heavy cream. Stir to combine, scraping any browned bits from the bottom of the pot.

1. Season the Soup: Add Worcestershire sauce, Italian seasoning, paprika, and season with salt and pepper. Stir well.

1. Return the Beef: Return the cooked beef to the pot. Bring the soup to a gentle boil, then reduce heat and let it simmer for about 15 minutes.

1. Melt the Cheese: Stir in the shredded cheese until melted and smooth, creating a creamy texture.

1. Taste and Adjust: Taste the soup and adjust seasoning if necessary.

1. Serve: Ladle the soup into bowls, garnish with freshly chopped parsley, and enjoy!

With these straightforward steps, you'll create an amazing soup that’s rich in flavor and texture.
