How to Make Crock Pot Caramelized Onions

Peel and slice 2 large yellow onions thinly.
In your crock-pot, combine the sliced onions, 4 tablespoons of margarine or butter, and 1 teaspoon of salt.
Cover the crock-pot and cook on low for 8-10 hours, or until the onions are deeply caramelized and a rich brown color. Stir occasionally to prevent burning, especially during the last couple of hours.
Once caramelized, remove from the crock-pot and let cool slightly before using in your favorite recipes. Can be stored in an airtight container in the refrigerator for up to 5 days.
