Description
This Crockpot Balsamic Glazed Caramelized Onions recipe offers a slow-cooked, richly flavored side or topping made with sweet onions, tangy balsamic vinegar, and a touch of brown sugar for perfect caramelization. Using a crockpot allows the onions to cook low and slow, developing deep, sweet, and savory flavors with minimal hands-on effort.
Ingredients
Scale
Ingredients
- 4 large onions, thinly sliced
- ¼ cup balsamic vinegar
- ¼ cup unsalted butter, melted
- 1 tablespoon brown sugar
- Salt, to taste
- Black pepper, to taste
Instructions
- Prepare the onions: Peel and thinly slice the 4 large onions evenly to ensure they cook uniformly.
- Mix glaze: In a bowl, combine the melted unsalted butter, balsamic vinegar, and brown sugar until well blended.
- Combine in crockpot: Place the sliced onions into the crockpot, pour the balsamic glaze mixture over them, and season with salt and pepper to taste. Stir gently to coat the onions evenly.
- Cook slowly: Cover and cook on low heat for 6 to 8 hours, stirring occasionally if possible, until the onions are deeply caramelized and soft.
- Finish and serve: Taste and adjust seasoning if needed. Use the caramelized onions as a flavorful topping for steak, burgers, sandwiches, or as a side dish.
Notes
- Stir occasionally during cooking for even caramelization, though not required.
- Replace unsalted butter with olive oil for a dairy-free version.
- Use red or yellow onions for slightly different sweetness and flavor nuances.
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
- Reheat gently on the stovetop or microwave before serving.
