Ingredients

  • 2 pounds yellow onions, thinly sliced
  • ½ cup (1 stick) butter
  • 1 teaspoon salt

Instructions

  • Add the butter to a heavy-bottomed pot over low heat, and once melted, add the sliced onions and sea salt. Stir to combine, place a lid on top, and let the onions wilt for 30 minutes.
  • After 30 minutes, take the lid off of the skillet and toss the onions in the butter. Turn the heat up to medium-low, and let the onions continue to caramelize, uncovered, for 45 minutes, scraping the pan and stirring the onions occasionally.
  • Use the caramelized onions right away or store them in an airtight jar or container in the fridge for up to a week.

Notes

Pro tip: make more onions than you need for one specific recipe! Caramelized onions can be stored for up to a week in the fridge, so you'll have time to put them on all of the things before they go bad.
