Tips
  • Ingredient Notes:
  • Yello or sweet onions are the best choice of onions to caramelize. However, you can caramelize any type of onion.
  • Butter adds a rich buttery flavor to the onions, and can be replaced with all oil for a dairy-free version.
  • Tip
  • Frequent stirring and deglazing the pan with water will help to prevent the onions from burning.
  • Change up the water and use broth or beer to deglaze the skillet
