So, you've enjoyed a delicious prime rib dinner, and now you're left with a beautiful, meaty bone. Don't let it go to waste! There are several delicious and resourceful ways to repurpose your leftover prime rib bones. Here, we'll guide you through creating a flavorful prime rib bone broth in the oven, a culinary treasure that will enhance your future soups, stews, and sauces.
Why Make Prime Rib Bone Broth?
Prime rib bones are packed with collagen, minerals, and gelatin, making them an excellent base for a nutrient-dense broth. The slow cooking process in the oven helps extract these beneficial components, resulting in a rich, velvety liquid that adds depth of flavor to your dishes. Plus, it's a sustainable way to reduce food waste.
Ingredients and Equipment
Here's what you'll need:

- Leftover prime rib bones (with meaty bits attached)
- 1 large onion, quartered
- 4 carrots, roughly chopped
- 4 celery stalks, roughly chopped
- 1 head of garlic, cut in half crosswise
- 1 bunch of fresh thyme
- 1 bunch of fresh parsley
- 10-12 black peppercorns
- 2 bay leaves
- Cold water (enough to cover the bones)
- Large Dutch oven or heavy-bottomed pot with a lid
- Large mixing bowl
- Fine-mesh strainer
- Large storage containers or jars
Instructions: Oven-Baked Prime Rib Bone Broth
Follow these step-by-step instructions to create a delicious prime rib bone broth in your oven:
Step 1: Preheat and Prepare the Bones
Preheat your oven to 375°F (190°C). Place the prime rib bones in a single layer in the Dutch oven. Roast them for about 1 hour, allowing the bones to brown and release their flavors.
Step 2: Add Aromatics and Herbs
Remove the Dutch oven from the oven. Add the quartered onion, chopped carrots, celery, garlic, thyme, parsley, peppercorns, and bay leaves to the pot. Toss everything to combine, ensuring the bones and vegetables are well coated in the rendered fat.

Step 3: Cover with Water
Pour cold water into the Dutch oven, enough to cover the bones and vegetables by about an inch. This may seem counterintuitive, but starting with cold water helps extract the collagen and gelatin from the bones more effectively.
Step 4: Cook Low and Slow
Cover the Dutch oven with the lid and place it back in the oven. Reduce the temperature to 250°F (120°C). Let the broth simmer gently for 8-12 hours, checking occasionally to ensure the water level hasn't dropped too low. If it has, add more water as needed.
Step 5: Strain the Broth
Once the cooking time is up, carefully remove the Dutch oven from the oven. Let the broth cool slightly, then strain it through a fine-mesh strainer into a large mixing bowl. Discard the solids.

Step 6: Store or Freeze
Let the broth cool to room temperature, then transfer it to airtight storage containers or jars. You can store it in the refrigerator for up to 5 days or freeze it for up to 3 months. Skim any fat that solidifies on the surface before using.
Using Your Prime Rib Bone Broth
Now that you have your delicious prime rib bone broth, here are some ways to incorporate it into your cooking:
- Use it as a base for soups, such as French onion, beef and barley, or classic beef stew.
- Reduce it to create a rich, flavorful sauce for roasted meats, pasta, or vegetables.
- Add it to risottos or paellas for an extra layer of depth.
- Sip it as a comforting, nourishing drink on its own.
Embrace the versatility of your prime rib bone broth, and enjoy the delicious, sustainable results of your culinary efforts. Happy cooking!
