Ingredients: A Symphony of Flavors
To create this culinary masterpiece, you'll need:
- 2 cups leftover prime rib, thinly sliced
- 1 large onion, diced
- 3 carrots, diced
- 3 celery stalks, diced
- 4 cloves garlic, minced
- 6 cups beef broth
- 1 cup red wine (optional, but adds depth of flavor)
- 2 tbsp tomato paste
- 1 tsp dried thyme
- 1 tsp dried rosemary
- Salt and pepper, to taste
- 2 cups frozen peas
- 2 cups leftover mashed potatoes (optional, for a thicker soup)
- Fresh parsley, chopped (for garnish)
Preparation: The Road to Soup Heaven
Now that you've gathered your ingredients, let's embark on the journey to soup heaven:

Sautรฉing the Aromatics
In a large pot or Dutch oven, heat a drizzle of olive oil over medium heat. Add the onion, carrots, celery, and garlic. Cook, stirring occasionally, until the vegetables begin to soften, about 5-7 minutes.
Building the Flavor Base
Stir in the tomato paste, thyme, and rosemary. Cook for another minute, then pour in the beef broth and red wine (if using). Bring the mixture to a boil, then reduce the heat to low. Let it simmer for 15-20 minutes, allowing the flavors to meld together.
Adding the Prime Rib
Add the sliced prime rib to the pot, along with any accumulated juices. Gently stir to combine, and let it simmer for another 10 minutes. This will allow the flavors of the prime rib to infuse into the soup.

Thickening the Soup
If you'd like a thicker soup, stir in the leftover mashed potatoes. Alternatively, you can use a slurry of cornstarch and water to achieve the desired consistency. Bring the soup back to a simmer and cook for an additional 5 minutes.
Finishing Touches
Stir in the frozen peas and cook until they're heated through, about 3-5 minutes. Taste and adjust the seasoning with salt and pepper as needed. Ladle the soup into bowls, garnish with chopped parsley, and serve with crusty bread on the side.
Nutritional Information and Storage
This leftover prime rib soup recipe serves 6-8 and is packed with protein, vitamins, and minerals. Store any leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months.

Variations and Tips
For a heartier soup, consider adding cooked barley, lentils, or diced potatoes. You can also swap the red wine for more beef broth or a splash of balsamic vinegar. To make this soup vegetarian or vegan, use vegetable broth and omit the prime rib, replacing it with a plant-based protein like chickpeas or tofu.
So, the next time you're faced with leftover prime rib, don't despair. Instead, embrace the opportunity to create a delicious, comforting soup that's perfect for lunch or dinner. Happy cooking!
