Ingredients
Before you start, make sure you have the following ingredients ready:
- 2 cups leftover prime rib, thinly sliced
- 1 cup pearl barley, rinsed
- 1 large onion, diced
- 2 carrots, diced
- 2 celery stalks, diced
- 4 cloves garlic, minced
- 8 cups beef broth
- 1 can (14.5 oz) diced tomatoes
- 1 tbsp tomato paste
- 1 tsp dried thyme
- 1 tsp dried rosemary
- Salt and pepper, to taste
- 2 bay leaves
- 2 tbsp olive oil
- Fresh parsley, chopped (for garnish)
Instructions
Step 1: Sauté the vegetables
Heat olive oil in a large pot or Dutch oven over medium heat. Add onion, carrots, and celery, then cook until softened, about 5-7 minutes. Stir in garlic and cook for another minute.

Step 2: Add barley and spices
Stir in rinsed barley, thyme, rosemary, salt, and pepper. Cook for 2-3 minutes, allowing the barley to toast slightly and absorb the flavors.
Step 3: Add liquids and simmer
Pour in beef broth, scraping the bottom of the pot to deglaze any browned bits. Add diced tomatoes (with juice), tomato paste, and bay leaves. Bring the soup to a boil, then reduce heat to low, cover, and let it simmer for 25-30 minutes, or until the barley is tender.
Step 4: Add prime rib and adjust seasoning
Stir in the sliced leftover prime rib. Taste and adjust seasoning if needed. If you prefer a thicker soup, you can simmer it uncovered for a few more minutes to reduce the liquid. Remove bay leaves before serving.

Step 5: Serve and enjoy
Ladle the soup into bowls, garnish with chopped fresh parsley, and serve with crusty bread or dinner rolls. This hearty Leftover Prime Rib Barley Soup is perfect for a cozy dinner or meal prepping for the week ahead.
