This easy slow cooker beef bone broth recipe transforms simple ingredients into a nutrient-packed superfood in 18-36 hours. Made with roasted beef bones, vegetables, and apple cider vinegar, this homemade bone broth delivers collagen, minerals, and amino acids that support gut health, immunity, and joint function. Perfect for sipping warm or using as a cooking base.

Why This Slow Cooker Bone Broth Recipe Works

This recipe succeeds because it combines three critical elements: proper bone preparation, extended cooking time, and acid addition. Roasting the bones at 400°F develops deep flavor compounds through the Maillard reaction, while the 24-hour slow cooking process breaks down collagen into bioavailable gelatin. Apple cider vinegar helps extract minerals from the bones, creating a nutrient-dense broth that gels when cooled.

The slow cooker method maintains consistent low heat without requiring constant monitoring, making it accessible for busy home cooks. Unlike stovetop methods that risk boiling (which can create cloudy broth), the slow cooker’s gentle heat produces clear, flavorful results every time.

Nutritional Benefits of Homemade Bone Broth

Collagen and Gelatin:

Supports skin elasticity, joint health, and gut lining integrity. The slow cooking process converts tough collagen into easily digestible gelatin.

Essential Minerals:

High in calcium, magnesium, phosphorus, and potassium—crucial for bone health and muscle function.

Amino Acids:

Contains glycine (supports sleep and detoxification), proline (collagen synthesis), and glutamine (gut health).

Digestive Support:

The gelatin content helps heal and seal the gut lining, potentially reducing inflammation and improving nutrient absorption.

Immune Function:

Traditional remedy backed by modern research showing anti-inflammatory properties and immune system support.

Key Ingredients for Perfect Bone Broth

Essential Ingredients:

  • Mixed beef bones (3-4 lbs): Use oxtail, knuckle bones, neck bones, and short ribs for optimal collagen content. While beef is most common, chicken bones work equally well, as do bones from any other animal. Lamb bones produce an exceptionally fragrant broth worth trying.
  • Apple cider vinegar (2 tbsp): Draws minerals from bones without affecting taste
  • Aromatic vegetables: Carrots, celery, and onions add depth of flavor and natural sweetness to balance the rich bone flavor (keep peels for enhanced color and nutrients)
  • Bay leaf: Adds subtle herbaceous notes
  • Filtered water: Fills 7-quart slow cooker completely

Quality Matters:

Choose grass-fed, pasture-raised bones when possible. CAFO-raised animals often produce broth that won’t gel properly and may contain unwanted additives.

How to Make Slow Cooker Bone Broth: Step-by-Step

Step 1: Roast the Bones

Preheat oven to 400°F. Arrange the bones in a single layer on a rimmed baking sheet.

Optionally, you can season the bones with salt and pepper before roasting, although saving this for later allows for better control, depending on what you intend to use the broth for.

Roast for 60 minutes, flipping each bone over half way through cooking time. This step is non-negotiable, as it will confer a beautiful golden color to the bones and fill them with TONS of flavor, both of which will later get passed down to the broth…

Step 2: Prepare the Vegetables

Roughly chop the carrots, celery, and onions. Don’t bother peeling the vegetables—the skins will add nutrients and color to the broth. Place everything in a 7 quart slow cooker along with the bay leaf and apple cider vinegar.

Step 3: Combine and Fill

Add the hot roasted bones directly to the slow cooker. Fill completely with filtered water, until the bones are fully submerged.

The broth will simmer gently rather than boil vigorously, so there’s no risk of overflow. Just leave about an inch at the top for safety.

Step 4: Slow Cook Low and Long

Set the slow cooker to LOW, cover, and cook for 18-36 hours until the broth reaches a rich brown color and fills your kitchen with an incredible aroma. A 24-hour simmering time is recommended to extract maximum nutrients from the bones, though 18 hours will still produce excellent results if time is limited.

Step 5: Strain and Store

Once the broth is done to your liking, carefully remove the larger pieces with a slotted spoon and place them in a strainer set over a large bowl to collect the excess broth. Press them down to extract all the liquid they contain.

Strain the remaining broth through a fine-mesh sieve or colander lined with cheesecloth to catch even the smallest debris.

Finally, transfer your bone broth into individual jars and refrigerate promptly.

The fat will float to the surface and, when chilled, form a protective barrier that prevents air contact with your broth. Once cooled, you can remove some or all of this fat layer and save it for cooking—it’s incredibly flavorful and excellent for sautéing vegetables or roasting.

Expert Tips for Bone Broth Success

  1. Don’t Skip Roasting: This step is essential for flavor development
  2. Use Bone Variety: Mix marrow bones with joint bones for best texture
  3. Add Acid Early: Vinegar needs time to work on extracting minerals
  4. Keep Temperature Low: High heat creates cloudy, less nutritious broth
  5. Strain Twice: First through colander, then fine-mesh sieve for clarity
  6. Cool Quickly: Refrigerate within 2 hours to prevent bacterial growth
  7. Save the Fat: The rendered fat layer is excellent for cooking

Troubleshooting Common Bone Broth Issues

Problem: Broth doesn’t gel when cooled
Solution: Use more joint bones (knuckle, neck), cook longer, or add chicken feet for extra collagen

Problem: Cloudy broth
Solution: Keep temperature low, don’t boil, and ensure proper straining

Problem: Weak flavor
Solution: Always roast bones first, use proper bone-to-water ratio, cook minimum 18 hours

Problem: Too salty
Solution: Don’t add salt during cooking; season individual servings instead

Problem: Greasy texture
Solution: Refrigerate and remove solidified fat layer before reheating


Frequently Asked Questions

Q: How long does bone broth last in the refrigerator?

A: Properly stored bone broth lasts 5-7 days refrigerated or up to 6 months frozen.

Q: Can I reuse bones for a second batch?

A: No, after 18-36 hours of cooking, the bones have released all their collagen, minerals, and nutrients. A second batch would yield minimal nutritional value and weak flavor. It’s better to start fresh with new bones.

Q: Is it safe to cook bone broth for 24+ hours?

A: Yes, when kept at proper temperature (below 200°F) in a slow cooker designed for extended cooking.

Q: Why add apple cider vinegar?

A: The acid helps extract minerals from bones without affecting taste. You won’t taste it in the final product.

Q: Can I make bone broth without roasting the bones?

A: While possible, roasting is essential for proper flavor and color development.

Q: What’s the difference between bone broth and regular stock?

A: Bone broth cooks longer (18+ hours vs 4-6 hours), uses more bones, and focuses on extracting maximum nutrients.
