After enjoying a delicious prime rib, you might be left with a pile of bones that seem destined for the trash. But don't discard them just yet! These leftover prime rib bones are packed with flavor and can be repurposed into a variety of dishes. Here's a comprehensive guide on how to make the most out of your leftover prime rib bones.
Understanding Prime Rib Bones
Prime rib is a cut from the rib section of the cow, and it's known for its rich, beefy flavor. The bones you're left with are from the ribcage, and they're full of connective tissue and marrow that can add depth of flavor to your cooking. Here are some ways you can use them:
Make a Rich Beef Broth
One of the most common and rewarding ways to use leftover prime rib bones is to make a hearty beef broth. This broth can be used as a base for soups, stews, or even risottos. Here's a simple recipe to get you started:

- Preheat your oven to 425°F (220°C).
- Place the bones on a baking sheet and roast for about 30 minutes, or until they're browned and fragrant.
- Transfer the bones to a large pot and cover them with cold water. Add a roughly chopped onion, a few carrots, a few stalks of celery, a few cloves of garlic, a bay leaf, and some black peppercorns.
- Bring the mixture to a boil, then reduce the heat to low and let it simmer for at least 8 hours, or even overnight. The longer you let it simmer, the more flavorful your broth will be.
- Strain the broth through a fine-mesh sieve into a large bowl or another pot. Discard the solids.
- Let the broth cool, then refrigerate it overnight. The next day, you can skim the fat from the surface and use the broth as needed.
Create a Flavorful Stock for Soup
If you're short on time, you can make a quick beef stock using your leftover prime rib bones. This stock won't have the depth of flavor of a slow-simmered broth, but it will still add a nice beefy taste to your soups and stews. Here's how:
- Place the bones in a large pot and cover them with water.
- Add an onion, carrots, celery, garlic, and a few spices (like bay leaves, black peppercorns, and thyme).
- Bring the mixture to a boil, then reduce the heat and let it simmer for about 4 hours.
- Strain the stock and use it immediately, or refrigerate it for up to 5 days, or freeze it for up to 3 months.
Make a Beef Marrow Spread
The marrow inside the prime rib bones is a delicacy that can be used to make a spread for crackers, toast, or even vegetables. Here's how to prepare it:
- Preheat your oven to 400°F (200°C).
- Wrap the bones in aluminum foil and roast them for about 20-25 minutes, or until the marrow is soft and melted.
- Carefully remove the bones from the oven and let them cool slightly. Then, use a spoon to scoop out the marrow.
- Mix the marrow with some softened butter, salt, and pepper to taste. You can also add other flavors like garlic, herbs, or horseradish.
- Spread the mixture on toast, crackers, or vegetables and enjoy!
Use as a Base for a Rich Gravy
If you have some leftover meat and drippings from your prime rib, you can use the bones to make a rich, flavorful gravy. Here's how:

- Deglaze the roasting pan with some red wine or beef broth, scraping up any browned bits from the bottom.
- Transfer the liquid to a pot and add the prime rib bones.
- Simmer the mixture for about 30 minutes, then strain it through a fine-mesh sieve.
- Mix the strained liquid with some cornstarch or flour to thicken it, if desired.
- Stir in any leftover meat and drippings, and serve the gravy over mashed potatoes, rice, or pasta.
