Caramelized Onions are made by slowly cooking sliced onions in butter until they become soft, golden brown, and naturally sweet. They take about an hour to cook, but the low and slow method gives them their rich flavor.
I’ve used this method for years, and the biggest thing I’ve learned is not to rush them. Give the onions plenty of time over low heat, stir them as they cook, and let them slowly turn that beautiful golden brown.

How to Caramelize Onions
Prepare the Onions: Thinly slice the onions and separate them into rings.
Start Cooking: Melt the butter in a large skillet over low heat. Add the onions and spread them evenly in the pan.
Caramelize: Cook over low heat for about 60 minutes, stirring regularly, until the onions are soft and deep golden brown.
Tips I Found Helpful 💙
- Keep the heat low: Caramelized onions need time to slowly develop their color and sweetness.
- Don’t rush them: Give the onions about 60 minutes to become soft and deeply golden.
- Stir regularly: This keeps the onions cooking evenly and prevents them from burning.
Storage
Let the caramelized onions cool, then store them in an airtight container in the refrigerator for up to 4 days
