If you've found yourself with leftover prime rib bones after a lavish dinner, you might be wondering what to do with them. Don't let them go to waste! These bones are packed with flavor and can be repurposed into delicious meals or nutritious broths. Let's explore some creative and practical ways to utilize your leftover prime rib bones, inspired by the ingenious suggestions found on Reddit.
Make Beef Broth
One of the most popular and nutritious ways to use leftover prime rib bones is to make a rich, flavorful beef broth. This versatile liquid gold can be used as a base for soups, stews, or even risottos. Here's a simple recipe inspired by Reddit user u/cookingwithkids:
- Place the bones in a large pot or slow cooker.
- Add cold water to cover the bones, about 4-5 quarts.
- Add a roughly chopped onion, a few carrots, and some celery stalks for extra flavor.
- Bring to a boil, then reduce heat to low and let it simmer for 8-12 hours, occasionally skimming the fat from the surface.
- Strain the broth through a fine-mesh sieve, discarding the solids.
- Let it cool, then refrigerate overnight. The next day, skim the solidified fat from the top.
- Your beef broth is now ready to use or freeze for later.
Create Bone Marrow Treats for Pets
While not suitable for human consumption, bone marrow can be a tasty and nutritious treat for your furry friends. Reddit user u/petlovers420 suggests making homemade dog treats using the marrow from your leftover prime rib bones. Here's a simple recipe:

- Preheat your oven to 350°F (180°C).
- Carefully extract the marrow from the bones using a spoon or a marrow scoop.
- Mix the marrow with some whole wheat flour and an egg until a dough forms. You can also add some dog-friendly herbs or vegetables for extra nutrition and flavor.
- Roll out the dough and cut it into small, bite-sized treats.
- Place the treats on a parchment-lined baking sheet and bake for 20-25 minutes, or until golden brown and crispy.
- Let them cool completely before giving them to your pet.
Make Beef Stock for Plants
Believe it or not, beef stock can be an excellent fertilizer for your plants. Reddit user u/gardeninggeek swears by using beef broth to give her plants a nutrient boost. Here's how:
- Dilute your homemade beef broth with water at a 1:5 ratio (1 part broth to 5 parts water).
- Water your plants with the diluted broth, making sure not to overwater them.
- Repeat every 2-4 weeks for best results.
Create a Flavorful Base for Stews and Soups
Instead of making a full batch of beef broth, you can use your leftover prime rib bones to create a flavorful base for stews and soups. Reddit user u/souplover123 suggests roasting the bones first to enhance their flavor. Here's how:

- Transfer the bones to a pot, add some vegetables (like carrots, celery, and onions), and cover with water.
- Bring to a boil, then reduce heat and let it simmer for a few hours, occasionally skimming the fat from the surface.
- Strain the liquid and use it as a base for your favorite stew or soup recipe.
Make Beef Bone Marrow Butter
If you're a fan of compound butters, you'll love this recipe inspired by Reddit user u/foodieextraordinaire: beef bone marrow butter. This rich and flavorful spread is perfect for adding depth to your dishes. Here's how to make it:

- Add the marrow to the pan and cook until it melts and starts to brown slightly.
- Remove from heat and let it cool slightly.
