Equipment

Ingredients

  • 2 medium yellow onions sliced
  • 2 tablespoons butter or olive oil
  • ½ teaspoon kosher salt
  • water or broth as needed

Instructions

  • Caramelize the onions. Heat the butter or oil in a large sauté pan on medium heat and add the onions. Stir the onions for 2 minutes, then reduce the heat to low.
    Step one of caramelized onions: add onions to pan.
  • Continue caramelizing. Add the salt and continue stirring the onions every 2 to 3 minutes, allowing them to caramelize on the bottom before stirring again. If the onions start to stick or brown, add a few tablespoons of water to rehydrate them and deglaze the pan.
    Step two of caramelized onions: continue caramelizing.
  • Finish caramelizing. Continue cooking the onions for approximately 45 minutes or until they're caramelized to your liking.
    Step three of caramelized onions: finish caramelizing.
  • Use or store. Use the caramelized onions in a variety of recipes or store in a sealed container in the fridge for several days.

Notes

  • If using butter, make sure you also add at least one tablespoon of oil to increase the smoke point of the butter and prevent the butter from burning.
  • I think it's best to make caramelized onions in a stainless steel or cast iron pan, not a non-stick pan. You want all those dark crispy bits! 
  • Storage tip: They can be stored in the fridge for 4 to 5 days.
