Put Raw Sliced Onions in a Slow Cooker with These 2 Ingredients — A Simple Recipe That Transforms into Pure Comfort

 

How to Make It

Ingredients:

  • 3–4 large onions, peeled and thinly sliced

  • 2 tablespoons unsalted butter

  • 1 tablespoon balsamic vinegar or Worcestershire sauce

Directions:

  1. Layer the onions
    Place the sliced onions into the bottom of your slow cooker.

  2. Add butter and vinegar
    Dot the butter across the top of the onions. Drizzle the balsamic vinegar (or Worcestershire sauce) evenly.

  3. Set it and forget it
    Cook on low for 8–10 hours, or high for 4–5 hours, stirring once or twice if you're home. The onions should turn deep golden brown, soft, and fragrant.

Once done, these rich caramelized onions become a kitchen powerhouse. Here’s how you can use them:
