Slow Cooker Beef Bone Broth Recipes

Steps:

• Heat oven to 180C/160C fan/gas 4. Spread the bones out on a baking sheet and roast them for an hour, turning them over after 30 mins.
• Heat the slow cooker if necessary. Pack the veg into the slow cooker, add the bones and enough water to fill the pot to within 2cm of the top. Add the lemon juice and the bay leaves. Cover and cook on Low for 18-36 hours. The longer you cook the broth the darker it will become.
• Place a colander over a bowl and scoop out all the bones into the colander. Return any broth from the bowl to the pan. Strain all the liquid through a fine sieve. Taste, and season only if you need to. Allow the broth to cool and lift off the fat. Store in the fridge for up to 3 days or transfer to freezer bags once it has cooled.

Steps:

• Preheat oven to 375 degrees F (190 degrees C). Line a baking sheet with aluminum foil; spread beef bones out on prepared baking sheet.
• Roast bones in the preheated oven until browned, 25 to 30 minutes.
• Place carrots, celery, onion, garlic, peppercorns, and bay leaves in a slow cooker. Place roasted bones over vegetables; pour in enough cold water to cover bones. Add apple cider vinegar and kosher salt.
• Cook on Low for 8 hours. Pour broth through a fine-mesh strainer into a bowl and discard any strained solids.

Steps:

• Preheat the oven to 400 F.
• Arrange the oxtails and bones on a baking sheet and rub all of the pieces with the tomato paste. Roast the bones until very brown in spots, about 45 minutes.
• Transfer the roasted bones to a 7-quart slow cooker. Use a metal spatula to scrape up any of the brown bits from the baking sheet and add them to the slow cooker, too. Nestle in the carrots, celery, onion, garlic, parsley and bay leaves. Toss in the peppercorns. Pour in the vinegar and 8 cups water (the water should just cover the bones and vegetables).
• Set your slow cooker to low and cook anywhere from 12 to 24 hours, the broth will be deeper and stronger in flavor the longer it cooks.
• Once you've decided the broth is ready, remove the insert and transfer the bones and pieces of meat to a baking sheet with tongs. Strain the remaining broth through a fine sieve. Let cool to room temperature. Let the bones cool and pick off and reserve any good-looking pieces of meat to add to soups and stews.
• Store the bone broth in airtight containers for up to 5 days in the refrigerator or up to 3 months in the freezer. Serve hot with desired mix-ins.
