Ingredients Method Notes

Ingredients
  

  • 2 –3 large yellow or sweet onions
  • 2 tablespoons butter or oil or a mix
  • A pinch of salt
  • Optional: Splash of water broth, or wine for deglazing

Method
 

  1. Slice onions into thin, even slices (about 1/8" to 1/4" thick) for uniform cooking.
  2. Heat a heavy-bottomed skillet over low-medium heat and add butter, oil, or both.
  3. Add onions and sprinkle with a pinch of salt to help them release moisture.
  4. Cook slowly, stirring every 5 minutes to allow the onions to brown evenly without burning.
  5. Deglaze with a splash of water, broth, or wine if onions begin to stick or brown too quickly.
  6. Continue cooking and gently stirring for 30–60 minutes until onions are deep golden brown, soft, and sticky-sweet.

Notes

Use yellow onions for balanced flavor or sweet onions like Vidalia for extra sweetness. Don’t rush—low and slow is key to perfect caramelization. Store leftovers for up to 5 days or freeze in small portions for easy use later.
