Slow Cooker Caramelized Onions: Sweet, Dark & Memorable!

So memorable, these onions, just thin slices of onion cooked until soft and dark and sweet in the slow cooker. My recipe for Caramelized Onions is "extra special" thanks to tiny touches of brown sugar and dry sherry. And now? My recipe is "extra easy" by switching from cooking the onions on the stove to cooking them either in a slow cooker or "slow cooking in the oven". Real Food. Vegetarian, Easily Switched to Vegan. Low Cal. Low Carb. Weight Watchers Friendly. Gluten Free. Great for Meal Prep.
