  • 5-6 cups of sliced onions about 2 large onions
  • 2 tablespoons oil olive oil or avocado oil work great
  • ½ teaspoon salt
  • tablespoons deglazing liquid divided


  • Heat your pan over medium heat (no higher) and once hot, add the oil to coat the bottom of the pan.
  • Next, add the onions to the pan and mix them around to coat them in the oil and then spread them out into a somewhat even layer, letting them cook untouched for about 6-8 minutes.
  • Sprinkle in the salt and give the onions a little stir.
  • As they continue to cook, the onions will start sticking to the pan a bit more (this is when the fond starts forming).
  • When you notice they're starting to stick, deglaze the pan with about 1.5 tablespoons of liquid and then scrape the bottom of the pan to help break up the fond and stir the onions around.
  • Continue cooking the onions while stirring occasionally. Once you notice them starting to stick again, deglaze the pan with another 1.5 tablespoons of liquid.
  • Continue with this method until you’ve deglazed the onions for a total of three times.
  • After 30 minutes, turn the heat down to low and let them caramelize and deepen in color for another 10 minutes before removing them from the heat. 
  • Store in an airtight container in the fridge for several days.


You may need to turn your heat down to medium-low if your onions are getting too dark too quickly.
