Ingredients
Scale
Main Ingredients
- 2 pounds white onions, peeled and sliced thin
- 3 tablespoons butter
- 1 tablespoon brown sugar
- 1 teaspoon all purpose seasoning blend
Instructions
- Add Ingredients to Slow Cooker: Place the thinly sliced onions, butter, brown sugar, and all purpose seasoning blend into the slow cooker. Gently toss the ingredients together to ensure the onions are evenly coated with butter and seasoning.
- Slow Cook: Cover the slow cooker and cook on the low setting for 8 hours. This slow, gentle heat allows the onions to break down and develop their sweet, caramelized flavor.
- Monitor Moisture: Every couple of hours, check the onions for excess liquid. If there is too much moisture, slightly vent the lid to allow steam to escape, helping the onions caramelize instead of steaming.
- Serve: After 8 hours, once the onions are deeply browned and caramelized, remove from the slow cooker and serve immediately as desired.
Notes
- Using the slow cooker on low ensures the onions caramelize slowly without burning.
- Adjust the seasoning blend to your taste or substitute with herbs like thyme or rosemary.
- If you prefer a slightly quicker version, you can cook on high for about 4 hours but watch closely.
- Caramelized onions can be refrigerated for up to a week or frozen for longer storage.
