In a large pot, heat the olive oil over medium-high heat. Add the thinly sliced sirloin steak, season with salt and pepper, and cook until browned. Remove the steak and set aside.
In the same pot, add the diced onion and bell peppers. Sauté for about 5-7 minutes until the vegetables are tender. Stir in the minced garlic and cook for an additional minute.
Pour in the beef broth, Worcestershire sauce, and dried thyme. Bring the mixture to a simmer.
Once simmering, reduce the heat to low, and add the heavy cream. Stir well to combine.
Return the cooked steak to the pot and let everything simmer together for another 10 minutes, allowing the flavors to meld.
Stir in the shredded provolone cheese until melted and creamy. Adjust seasoning with salt and pepper if needed.
Serve the soup hot, garnished with chopped parsley for a fresh touch.
Notes
