  1. Peel your onions and then cut them in half, then into roughly 1/4" slices.
  2. In the bowl of your slow cooker, toss together the onions and oil to coat, then add the salt and toss again to combine.
  3. Cook 8 hours on the low setting with the cover on, then remove the cover and continue to cook an additional 1-2 hours until the onions crisp up. If you prefer softer onions, leave the cover on for the final 1-2 hours. Once the onions reach a deep amber color, they are done.


Store leftovers in an airtight container in the fridge for up to a week.
