Ingredients
Scale
Ingredients
- 4 large onions, thinly sliced
- ¼ cup balsamic vinegar
- ¼ cup unsalted butter, melted
- 1 tablespoon brown sugar
- Salt and pepper, to taste
Instructions
- Prepare the onions: Peel and thinly slice 4 large onions to ensure they cook evenly and absorb the glaze thoroughly during slow cooking.
- Mix the glaze: In a bowl, combine ¼ cup balsamic vinegar, ¼ cup melted unsalted butter, and 1 tablespoon brown sugar. Stir well until the sugar dissolves and the mixture is smooth.
- Combine ingredients in crockpot: Place the sliced onions in the slow cooker. Pour the balsamic glaze over the onions and sprinkle with salt and pepper to taste. Stir gently to coat the onions evenly with the glaze.
- Cook low and slow: Cover and cook the onions on low heat in the crockpot for 6 to 8 hours or until the onions are deeply caramelized, soft, and richly flavored. Stir occasionally if possible.
- Serve or store: Once caramelized, give the onions a final stir. Serve warm as a topping for burgers, steaks, or pizzas, or let cool and store in an airtight container in the refrigerator for up to one week.
Notes
- For extra depth of flavor, add a sprig of fresh thyme or a crushed garlic clove during cooking.
- If you prefer a thicker glaze, you can reduce the balsamic vinegar slightly before adding it to the crockpot.
- These onions pair exceptionally well with grilled meats, sandwiches, and roasted vegetables.
- Make sure to use thinly sliced onions for quicker, even caramelization.
