In a large pot, heat the olive oil over medium heat. Add the diced onion and bell pepper, sautéing until soft, about 5 minutes.
Add the thinly sliced sirloin steak to the pot. Cook for another 5-7 minutes until the meat is browned, stirring frequently.
Stir in the minced garlic and cook for 1 minute more until fragrant.
Pour in the beef broth, Worcestershire sauce, salt, black pepper, and paprika. Bring the mixture to a simmer and allow to cook for 15 minutes.
Lower the heat and stir in the heavy cream and softened cream cheese until fully combined and creamy, about 3-5 minutes.
Sprinkle in the shredded provolone cheese and stir until melted and incorporated into the soup.
If you prefer a smoother soup, you can use a blender to puree it cautiously and return it to the pot. Otherwise, serve it as is.
Ladle the soup into bowls and garnish with fresh parsley if desired.
