Cooking Instructions for Leftover Prime Rib Soup
Sautéing the Vegetables
Begin by heating the olive oil in a large pot or Dutch oven over medium heat. Add the diced onion, carrots, and celery, then cook, stirring occasionally, for about 5 minutes until the vegetables start to soften.

Stir in the minced garlic and cook for an additional 1 minute, until fragrant. Be careful not to burn the garlic.
Building the Soup Base
Pour in the beef broth and water, then add the leftover prime rib, diced potatoes, bay leaf, thyme, and rosemary. Stir well to combine. Bring the soup to a boil, then reduce the heat to low, cover, and let it simmer for 15-20 minutes, or until the potatoes are tender.
Season the soup with salt and pepper to taste. If you prefer a thicker soup, mix together the cornstarch and cold water in a small bowl, then stir it into the pot. Cook for an additional 2-3 minutes, until the soup has thickened to your desired consistency.
