Ingredients

Ingredients

  • 3 medium onions
  • 1 Tbsp olive oil
  • 1 Tbsp butter
  • ½ tsp salt

Instructions

  1. Slice: Peel the onions completely and slice them into even strips to ensure uniform cooking.
  2. Melt Butter and Oil: Place a pan over medium-high heat and melt the butter along with the olive oil to create a rich cooking base.
  3. Coat: Add the sliced onions to the pan and use tongs to evenly coat them in the melted butter and oil mixture.
  4. Season: Sprinkle salt over the onions, which helps to draw out moisture and accelerates the caramelization process.
  5. Cook Initially: Cook the onions on medium-high heat for 5 to 10 minutes until they start to soften and turn a light golden color.
  6. Lower Heat: Reduce the heat to medium and continue cooking the onions for an additional 35 to 40 minutes, stirring every few minutes to prevent sticking and promote even caramelization.
  7. Serve: When the onions are a deep golden brown and fully soft, remove from heat. The caramelized onions are now ready to be served or used to enhance your favorite recipes.

Notes

  • Stir frequently to avoid burning and ensure the onions caramelize evenly.
  • Use a heavy-bottomed pan for even heat distribution.
  • Patience is key — slow cooking enhances the flavor and sweetness of the onions.
  • Caramelized onions can be stored in the refrigerator for up to a week.
  • Adjust salt to taste, and consider adding a splash of balsamic vinegar for a tangy twist if desired.
