There’s something deeply comforting and restorative about a warm cup of homemade bone broth. It’s a liquid gold, packed with collagen, minerals, and amino acids that support gut health, joint mobility, and glowing skin. This slow cooker recipe is my go-to for a truly hands-off approach to creating the most flavorful and nutrient-dense broth. Whether you’re following a keto lifestyle or simply want to add a powerhouse of nutrition to your diet, this recipe is your perfect starting point. Let it simmer away for a few days, and your kitchen will be filled with the most incredible, savory aroma!
Ingredients
• 4 quarts / 3.8 liters cold water (filtered or reverse-osmosis is best)
• 4 pounds / 1.8 kg large beef bones, leftover bones from 1 pastured chicken (with feet), or fish bones and heads
• 1 medium onion, chopped
• 2 stalks celery, sliced
• 2 tablespoons / 30 ml coconut vinegar or apple cider vinegar
• 2 tablespoons / 8 g fresh rosemary leaves
• 2 teaspoons / 6 g minced garlic
• 2 teaspoons / 12 g fine sea salt
• 1 teaspoon / 1 g fresh thyme leaves (or ¼ heaping teaspoon dried)
Instructions
1. Combine all in a 6-quart or larger slow cooker. Secure the lid and set the heat to high for 1 hour.
2. After the first hour, reduce the heat to low. Allow the broth to simmer for a minimum of 24 hours (1 day) and up to 72 hours (3 days). The longer it simmers, the more rich and nutrient-dense it will become.
3. Once the simmering is complete, carefully pour the broth through a fine-mesh strainer into a large bowl or pot. Discard the bones and vegetable solids.
4. Do not skim the fat from the surface; this healthy fat is key for a keto-friendly broth and adds incredible flavor and satiety.
5. Let the broth cool before transferring it to airtight containers. Store in the refrigerator for up to 5 days or freeze in portions for up to 6 months.

Pro Tips
• For a deeper, richer flavor, roast beef or chicken bones in the oven at 400°F / 200°C for 30-45 minutes until golden brown before adding them to the slow cooker.
• A high-quality broth will become gelatinous and jiggly when chilled. This is a sign of a high collagen content! If yours doesn’t gel, try adding more joint-rich bones like chicken feet or beef knuckles next time.
• Freeze your finished broth in ice cube trays or silicone muffin molds. Once frozen, transfer the pucks to a freezer bag for perfectly portioned broth ready for sipping or adding to sauces and recipes.
• Check the water level every 24 hours. If it has reduced significantly, top it off with a bit of hot filtered water to ensure the bones remain submerged.
FAQ
Q: Why didn’t my bone broth gel
A: A gelatinous, jiggly texture when chilled is a great sign of high collagen content. If your broth doesn’t gel, try adding more joint-rich bones like chicken feet or beef knuckles to your next batch to increase the collagen.
Q: How long should I cook bone broth in a slow cooker
A: This recipe calls for simmering the broth on low for a minimum of 24 hours and up to 72 hours (3 days). The longer it simmers, the more flavor and nutrients will be extracted from the bones.
Q: How can I make my bone broth more flavorful
A: For a deeper, richer flavor, roast your beef or chicken bones on a baking sheet at 400°F / 200°C for 30-45 minutes until they are golden brown. Then, add the roasted bones to your slow cooker as instructed.
Q: How should I store homemade bone broth
A: Once cooled, you can store the broth in airtight containers in the refrigerator for up to 5 days. For longer-term storage, freeze it in portions for up to 6 months. Using ice cube trays or silicone muffin molds is a great way to freeze convenient, single-serving portions.
