BONE MARROW BROTH SLOW COOKER RECIPES

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.

Steps:

• If you want to roast the bones first, heat the oven to 450ºF. Lay the bones out on a rimmed baking sheet and roast until well browned, 25 to 35 minutes.
• Put the bones (roasted or not) in the pressure cooker pot and add all the remaining ingredients. Cover with 3 to 3 1/2 quarts of water (the water shouldn’t come more than two-thirds of the way up the side of the pot). To make regular stock, cook on high pressure for 1 hour if using all chicken or poultry bones, or 2 hours for beef or pork bones or a combination of poultry and meat. For bone broth, cook on high pressure for 3 hours for poultry bones, and 4 1/2 hours for beef, pork, or mixed bones. When making bone broth, you’ll know you’ve cooked it long enough if all the connective tissue, tendons, and cartilage have dissolved and the bones crumble a bit when you poke at them. If this hasn’t happened, cook it on high pressure for another 30 minutes and check it again.
• Allow the pressure to release naturally. Use the broth or stock right away, or store it in the refrigerator or freezer. Bone broth and regular stock will keep for 5 days refrigerated or up to 6 months frozen.
