Description

This Crockpot Balsamic Glazed Caramelized Onions recipe offers a simple, hands-off approach to achieving perfectly soft, sweet, and deeply flavorful caramelized onions. Utilizing a slow cooker, this method enhances the natural sweetness of onions with balsamic vinegar and brown sugar, making them an ideal savory-sweet topping for burgers, steaks, sandwiches, or a flavorful addition to various dishes.


Ingredients

Scale

Onions

  • 4 large onions, thinly sliced

Glaze

  • ¼ cup balsamic vinegar
  • ¼ cup unsalted butter, melted
  • 1 tablespoon brown sugar
  • Salt and pepper, to taste


Instructions

  1. Prepare the onions: Peel and thinly slice 4 large onions to ensure they cook evenly and caramelize well in the crockpot.
  2. Combine glaze ingredients: In a bowl, mix ¼ cup balsamic vinegar, ¼ cup melted unsalted butter, 1 tablespoon brown sugar, and salt and pepper to taste until the sugar dissolves.
  3. Add onions and glaze to crockpot: Place the sliced onions into the slow cooker and pour the balsamic glaze over them. Stir gently to coat all the onion slices evenly with the glaze.
  4. Cook low and slow: Cover the crockpot and cook on low for 8 hours, stirring occasionally if possible. This slow cooking process allows the onions to soften and caramelize beautifully, developing a rich, sweet flavor.
  5. Finish and serve: After 8 hours, taste and adjust seasoning with salt and pepper if needed. Use the balsamic glazed caramelized onions as a topping or flavor enhancer for your favorite dishes.

Notes

  • Ensure onions are sliced uniformly for even cooking.

  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • These caramelized onions pair exceptionally well with grilled meats, sandwiches, and roasted vegetables.
