- 2 tbsp olive oil

Instructions
Sauté the Vegetables
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced onion, carrots, and celery, and cook until the vegetables begin to soften, about 5-7 minutes. Stir in the minced garlic and cook for an additional 1 minute.

Add the Broth and Prime Rib
Pour in the beef broth and water, then add the sliced or shredded leftover prime rib. Stir in the tomato paste, thyme, rosemary, salt, pepper, and bay leaves. Bring the soup to a boil, then reduce the heat to low, cover, and let it simmer for 20-25 minutes.
Add Mushrooms and Cream (Optional)
If using mushrooms, add them to the pot and cook for an additional 10 minutes, until they're tender. If you'd like a richer soup, stir in the heavy cream and cook for an additional 5 minutes.
Serve and Enjoy
Taste the soup and adjust the seasoning if needed. Ladle the soup into bowls, garnish with fresh chopped parsley, and serve with crusty bread or dinner rolls. Enjoy your delicious and comforting leftover prime rib soup!
