Instructions
Prepare the onion by removing the ends, peeling the outer dried layers and then slicing the onion into roughly 1/2" slices.
Place onions in the slow cooker and toss them with the oil, salt, and pepper to coat.
Cook on low for 8-12 hours or until the onions are a deep caramel color.Note: If the onions have more liquid than you prefer, you can set the lid slightly ajar for the last 1-2 hours of cooking time to help them thicken up and become more jammy.
Stir the onions and serve immediately, or save in the fridge for up to a week, or freezer for up to 3 months.
Notes
What onions should I use for caramelized onions?
Any traditional style onion will work! My favorites are:
Yellow onions
Sweet onions
Vidalia onions
Red onions
The first three are naturally sweeter so they produce that very signature sweet caramelized onion flavor well. Red onions turn to a beautiful purple color when caramelized and also have great flavor.You can use one of these, or do a mixture of several.
