Cooking Instructions for Beef Soup with Leftover Prime Rib
Sauté the Aromatics
In a large Dutch oven or pot, heat the olive oil over medium heat. Add the diced onion, sliced carrots, and celery. Cook, stirring occasionally, until the vegetables begin to soften, about 5-7 minutes.

Add the minced garlic and cook for another minute, until fragrant. Be careful not to burn the garlic.
Add the Prime Rib and Seasonings
Increase the heat to medium-high and add the sliced leftover prime rib to the pot. Cook, stirring occasionally, until the meat is lightly browned, about 5-7 minutes. This step adds extra flavor to your soup.
Stir in the tomato paste, thyme, and rosemary. Cook for another minute, allowing the tomato paste to darken slightly and release its flavors.

Simmer the Soup
Pour in the beef broth and red wine (if using). Stir well to combine, scraping the bottom of the pot to deglaze and release any browned bits.
Bring the soup to a boil, then reduce the heat to low. Cover the pot and let it simmer for 20-25 minutes, allowing the flavors to meld together.
Add Pasta and Peas
Stir in the frozen peas and egg noodles. Cook for an additional 8-10 minutes, or until the pasta is al dente and the peas are heated through.

Season and Serve
Taste the soup and adjust the seasoning with salt and pepper as needed. Ladle the beef soup into bowls and garnish with chopped fresh parsley. Serve hot and enjoy your delicious repurposed prime rib meal!
Tips for Making the Best Beef Soup with Leftover Prime Rib
Here are some tips to help you make the most of your leftover prime rib and create an exceptional beef soup:
- Use high-quality beef broth: The quality of your broth greatly impacts the final flavor of your soup. Opt for homemade or high-quality store-bought broth for the best results.
- Deglaze the pot: Don't skip this step! Deglazing releases the flavorful browned bits from the bottom of the pot, enhancing the overall taste of your soup.
- Add pasta at the end: Adding pasta towards the end of cooking prevents it from becoming overcooked and mushy. Plus, it helps thicken the soup slightly.
- Customize your soup: Feel free to add other vegetables like potatoes, corn, or green beans to suit your preferences. You can also make it a heartier meal by adding some leftover mashed potatoes or crusty bread on the side.
With this beef soup recipe, you'll transform your leftover prime rib into a comforting and satisfying meal that's perfect for any occasion. Enjoy!
