After a lavish holiday feast or a special Sunday dinner, you might find yourself with leftover prime rib roast bones. Instead of tossing them, consider these creative and eco-friendly ways to repurpose them. Not only will you reduce waste, but you'll also unlock hidden culinary and household benefits. Let's dive into what to do with leftover prime rib roast bones.
Make Flavorful Stock or Broth
Transform leftover bones into a rich, hearty stock or broth that can elevate your soups, stews, and sauces. Here's a simple recipe to get you started:
- Place the bones in a large pot or slow cooker.
- Add vegetables like carrots, celery, and onions for extra flavor.
- Cover with water, bring to a boil, then reduce heat and let it simmer for 8-12 hours.
- Strain the liquid, discard the solids, and voila! You have a delicious, homemade stock.
Create Bone Broth for Health Benefits
Bone broth, a nutrient-dense liquid extracted from simmering bones, has gained popularity for its potential health benefits. It's rich in collagen, amino acids, and minerals that support joint health, gut healing, and immune function. To make bone broth, follow these steps:

- Roast the bones at 400°F (200°C) for 30 minutes to enhance flavor.
- Place the roasted bones in a pot, cover with water, and add an acid like apple cider vinegar to help extract minerals.
- Bring to a boil, then reduce heat and let it simmer for 12-24 hours.
- Strain the liquid, and enjoy your nutritious bone broth as is or use it in recipes.
Repurpose Bones for Pets
Raw, meaty bones are an excellent treat for dogs, providing them with essential nutrients and helping maintain dental health. Always ensure the bones are uncooked and unseasoned, and supervise your pet while they enjoy their treat. For cats, you can provide them with small, raw meaty bones like chicken necks or wings, but avoid giving them large, weight-bearing bones.
Make Bone Meal Fertilizer
Bone meal, a fine powder made from ground animal bones, is a rich source of phosphorus and calcium, essential nutrients for plant growth. To make bone meal fertilizer, follow these steps:
- Clean and dry the bones thoroughly.
- Grind the bones into a fine powder using a blender or food processor.
- Spread the bone meal evenly over your garden or potted plants, ensuring it's well-incorporated into the soil.
Create Art or Craft Projects
For the artistically inclined, leftover bones can inspire unique art and craft projects. Here are a few ideas:

- Create bone jewelry, such as necklaces, bracelets, or earrings, by drilling holes into the bones and stringing them with beads or cord.
- Make bone wind chimes by suspending bones from a string or wire, allowing them to clatter gently in the breeze.
- Transform bones into decorative home accents, like wall art, candle holders, or table centerpieces.
Donate to Science or Education
If you're not interested in repurposing the bones yourself, consider donating them to local schools, universities, or science institutions. These organizations may use the bones for educational purposes, such as teaching anatomy or comparative biology.
