By repurposing your leftover prime rib, you're not only being resourceful but also creating a delicious and nourishing meal.

Basic Vegetable Soup with Leftover Prime Rib
This classic recipe lets the prime rib shine while providing a comforting backdrop of vegetables and herbs.
| Ingredients | Quantity |
|---|---|
| Leftover prime rib | 2 cups, shredded or diced |
| Onion | 1 medium, diced |
| Carrots | 2 medium, diced |
| Celery | 2 stalks, diced |
| Garlic | 2 cloves, minced |
| Potatoes | 2 medium, diced (optional) |
| Vegetable or beef broth | 8 cups |
| Tomatoes | 1 can (14.5 oz), diced or crushed |
| Thyme | 1 tsp |
| Rosemary | 1 tsp |
| Bay leaves | 2 |
| Salt and pepper | To taste |
| Olive oil | 2 tbsp |
In a large pot, heat olive oil over medium heat. Add onions, carrots, celery, and garlic, cooking until softened. Stir in potatoes (if using), tomatoes, broth, herbs, and prime rib. Bring to a boil, then reduce heat, cover, and let simmer for 20-25 minutes, or until potatoes are tender. Season with salt and pepper, and serve.
Hearty Prime Rib and Vegetable Stew
For a thicker, heartier soup, try this stew-like variation.

Follow the same steps as the basic recipe, but after adding the broth, bring the soup to a boil, then reduce heat to low. Let it simmer, uncovered, for 30-35 minutes, stirring occasionally. This allows the soup to reduce and thicken naturally. If you prefer a thicker consistency, you can also add a slurry of cornstarch and water towards the end of cooking.
Tips for Making the Most of Your Leftover Prime Rib
To ensure your leftover prime rib maintains its tenderness and flavor, consider these tips:
- Store leftover prime rib in an airtight container in the refrigerator for up to 4 days.
- When ready to use, shred or dice the meat against the grain to maintain tenderness.
- If your prime rib has been refrigerated for a few days, consider briefly searing it before adding to the soup to rejuvenate its flavor.
Don't let leftover prime rib go to waste. With these vegetable soup recipes, you can create a delicious and satisfying meal that's perfect for lunch or dinner. Happy cooking!
