Description
This Crockpot Balsamic Glazed Caramelized Onions recipe offers a sweet and savory side dish with deep, rich flavors developed through slow cooking. Using a slow cooker (crockpot), the onions become tender and caramelized while absorbing the tangy balsamic glaze, perfect for topping meats, sandwiches, or adding flavor to various dishes.
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: Thinly slice the onions to ensure they cook evenly and become perfectly caramelized during the slow cooking process.
- Mix glaze ingredients: In a small bowl, combine the melted unsalted butter, balsamic vinegar, and brown sugar. Stir until the sugar dissolves and the mixture is well blended.
- Combine in crockpot: Place the sliced onions in the crockpot, pour the balsamic glaze mixture over them, and lightly stir to coat the onions evenly. Season with salt and pepper to taste.
- Slow cook the onions: Cover and cook on low for 10 hours, stirring occasionally if possible. The long, slow cooking process allows the onions to caramelize deeply, and the balsamic glaze to reduce and coat the onions beautifully.
- Finish and serve: Once done, give the onions a final stir, adjust seasoning with more salt and pepper if desired, and serve warm as a flavorful side or topping.
Notes
- Use sweet onions like Vidalia or yellow onions for best flavor and natural sweetness.
- If short on time, cook on high for 4-5 hours but low and slow is recommended for optimal caramelization.
- These caramelized onions can be refrigerated for up to 5 days or frozen for longer storage.
- Great addition to burgers, steaks, salads, pizzas, and sandwiches.
