This recipe will guide you through creating a rich, satisfying Leftover Prime Rib Roast Soup that's perfect for chilly evenings or meal prepping for the week ahead.
Ingredients and Preparation
Before you begin, ensure you have the following ingredients ready:
- 2 lbs leftover prime rib roast, sliced
- 1 large onion, diced
- 3 carrots, diced
- 3 celery stalks, diced
- 4 cloves garlic, minced
- 1 cup red wine (optional, but adds depth of flavor)
- 8 cups beef broth
- 2 bay leaves
- 1 tbsp tomato paste
- Salt and pepper, to taste
- 2 tbsp olive oil
- Fresh parsley, chopped (for garnish)
Equipment
- Large Dutch oven or heavy-bottomed pot
- Wooden spoon
- Immersion blender or regular blender
Instructions
Start by heating the olive oil in your Dutch oven over medium heat. Add the diced onions, carrots, and celery, cooking until the onions are translucent and the vegetables begin to soften, about 5-7 minutes.

Stir in the minced garlic and cook for an additional 1 minute, until fragrant. Pour in the red wine (if using) and scrape the bottom of the pot to deglaze, allowing the wine to reduce by half.
Add the sliced leftover prime rib roast to the pot, stirring to combine with the vegetables and wine. Cook for 5-7 minutes, allowing the beef to brown slightly.
Stir in the tomato paste, followed by the beef broth. Add the bay leaves, and bring the soup to a boil. Once boiling, reduce the heat to low, cover, and let it simmer for 20-25 minutes, allowing the flavors to meld together.

Using an immersion blender, partially blend the soup until it reaches your desired consistency. Be careful not to over-blend, as you still want some chunks of beef and vegetables for texture. If you don't have an immersion blender, carefully transfer the soup in batches to a regular blender, then return it to the pot.
Taste and adjust seasoning with salt and pepper as needed. Ladle the soup into bowls, garnish with chopped fresh parsley, and serve hot. Enjoy your delicious Leftover Prime Rib Roast Soup!
