Author: Michelle - Cup of Zest
Makes: 1

Ingredients

  • 1 tbsp. unsalted butter
  • 1 tbsp. olive oil
  • 2 medium brown onions sliced
  • ½ cup apple cider vinegar
  • ½ tsp. kosher salt

Instructions

  • Melt butter in a large skillet over medium heat. Add olive oil.
  • Add sliced onions and stir to coat in that delicious melted fat.
  • Let the onions cook, giving them a stir every 5-10 minutes to ensure even caramelization. At about 20 minutes into cooking, you should notice some brown bits forming/sticking to the pan.
  • When this happens, add 1 tbsp. vinegar to the pan while scraping the brown bits with a wooden spatula (you are degazing the pan when you do this). Continue to deglaze the pan as needed with the remaining vinegar.
  • Cook the onions until they are a deep brown and very soft, about 50 minutes total. Salt those amazing onions and eat up!

Notes

It is best to use a stainless skillet in this recipe. You DO want the onions to stick to the pan when cooking them, which will not happen with a nonstick skillet.
If you run out of vinegar and still need to deglaze the pan, just use water.
If your onions start to burn, just turn down the heat to medium-low or low.
