Ingredients
3
pounds
yellow onions
2-3
Tablespoons
olive oil
1
Tablespoon
balsamic vinegar
Instructions
Uniformly slice onions with a mandolin or knife. I used setting 3 on a mandolin.
Place onions in slow cooker and drizzle with olive oil. Toss to coat all the onion slices.
Cover and cook on low for 10 hours.
Remove lid and stir in balsamic vinegar.
Return lid and leave ajar to allow liquid to begin evaporating.
Cook for 1 hour more on low.
Remove onions from slow cooker.
Place onions in a colander to drain off liquid. Liquid can be retained for another use.
Portion and freeze onions in a freezable containers or plastic bags according to needs. ¼ cup portion sizes work well.
