A mouthwatering recipe for the best homemade Prime Rib soup made with leftover Standing Rib Roast. This flavorful beef vegetable soup recipe is made with Pappardelle pasta, and I’ve also included a gluten-free recipe variation swapping the pasta for potatoes. Either way, it’s incredibly delicious!!
One of my favorite things about making a Standing Rib Roast is having leftovers to repurpose for more tasty meals. Prime Rib is an expensive cut of meat, but it actually goes a long way when you use any extra meat for sandwiches and salads, in addition to whipping up a big pot of this delicious beef soup from the Prime Rib bones. It’s worth the investment for all these tasty meals! Not to mention, you can often find them on sale if you watch local grocery store flyers around the holidays.
How To Freeze Leftover Prime Rib Bones
To freeze the ribs from a Standing Rib Roast, allow them to cool to room temperature, then wrap them tightly in plastic wrap. Store them in an airtight container in the freezer for up to 6 months.
Steps For Making Prime Rib Soup
First, place the rib bones in a Dutch oven and add 4 cups of water, 4 cups of beef broth, 1 tbsp beef bouillon, wine, garlic, thyme, barley, ribs, and bay leaf. When using frozen rib bones, allow them to defrost overnight in the refrigerator before cooking in the stock. Bring to a boil, reduce heat to low, and simmer for 2 hours with the lid on. Allow the bone broth to cool, remove the ribs, and shred the meat from the bones. It should be easily falling off the bone, like this…
Discard the bones, add the shredded beef back to the pot, and refrigerate overnight.
The next day, skim the fat off the top of the soup and discard. Chop the carrots, celery, and onions and heat a tablespoon of olive oil in a skillet over medium heat.
Add the carrots, onion, and celery to the skillet and sauté for 5 minutes on medium-low heat, stirring occasionally, until vegetables have softened.
Add the remaining 2 cups of broth to the soup base and bring to a boil. Then, add the onion, celery, carrots, and frozen vegetables. Season with salt and pepper. Simmer the soup for 35 minutes with the lid vented. Add pappardelle, breaking into pieces as you drop the noodles into the soup, (or cubed potatoes for GF) and cook 10-15 minutes more until noodles are done or potatoes are easily pierced with a fork.
If you prefer a more stew-like soup texture, cook the pasta in the soup as directed above. The starch in the noodles will thicken the soup and soak up some of the broth. If you prefer a brothier soup, cook the pasta in a separate pot according to package directions for an al dente texture. Drain the cooked noodles and add them to the soup right before serving.
Who’s ready for a warm pot of delicious soup?!
