Description
A classic caramelized onions recipe that transforms sweet onions into rich, golden-brown, deeply flavored strands perfect for enhancing a wide variety of dishes. Slow-cooked in butter and oil, these onions add a sweet umami boost to sandwiches, soups, and more.
Ingredients
Ingredients
- 2 large sweet onions
- 2 tbsp butter
- 1 tbsp oil (vegetable or olive oil)
- Pinch of salt
Instructions
- Prepare the onions: Remove the papery outer layers of the onions to reveal the smooth flesh beneath.
- Slice the onions: Using a sharp knife or mandoline, cut the onions into slices about 1/4 inch thick for even cooking.
- Heat the pan: Place a heavy-bottomed or cast iron pan on medium-low heat, adding the oil to warm up gently.
- Add ingredients to the pan: Add the sliced onions, butter, and a pinch of salt to the pan, coating them evenly with the fat.
- Slowly cook the onions: Stir the onions every five minutes to prevent burning and encourage even caramelization. The onions will wilt down, reduce in volume, and turn a golden brown.
- Finish caramelizing: Continue cooking and stirring for 35 to 40 minutes until the onions are deeply browned, sweet, and tender.
- Serve and enjoy: Use caramelized onions as a delicious addition to your favorite recipes or enjoy them on their own.
Notes
- Cook onions slowly over medium-low heat to prevent burning and promote even caramelization.
- Use a heavy-bottomed or cast iron pan for better heat distribution.
- Stir frequently, roughly every five minutes, to avoid sticking and scorching.
- You can add a splash of water if onions start to stick before they caramelize.
- Caramelized onions can be stored in the fridge for up to 5 days or frozen for longer storage.
- Use sweet onions for best natural sweetness, but yellow onions also work well.
