Add everything to the crock pot: Chicken bones and skin, veggies, peppercorns, salt, all of it. Pour in the leftover juices for extra flavor.
Fill with water: Add enough water to cover everything and fill to the top of your slow cooker, leaving a little room so it doesn’t overflow.
Cook on low for 8–12 hours: Overnight is perfect! Your home will smell unbelievable by morning.
Strain the broth. Remove the big pieces with tongs, then pour the liquid through a fine strainer.
Store it. Fill Mason jars or airtight containers.Refrigerate for up to 5 daysFreeze for up to 3 months (we like to freeze in souper cubes) Or can it, if that’s your thing!
