How To Make Caramelized Onions

Step #2. Slice them thinly into even rings or strips.
Step #3. In a medium-sized, heavy-bottomed pot, heat the butter over medium-low heat. Allow the butter to melt completely.
Step #4. Begin by adding half of the sliced onions to the pot. Stir to coat them evenly with the butter and oil. Sprinkle with a pinch of salt.

- Caramelizing onions takes time. Depending on your desired level of caramelization, it can take anywhere from 30 to 40 minutes. Stirring every few minutes helps ensure even cooking.

Notes

- If your pot isn’t large enough to hold all the sliced onions without crowding, consider cooking them in batches to ensure even caramelization.
