Ingredients

Onion Mixture

  • 2 lb / 1 kg onions (peeled and sliced; white, sweet, red, or yellow onions all work great)
  • 1 tbsp olive oil
  • 1 tbsp butter (or a second tablespoon of olive oil)
  • 3/4 tsp salt
  • 1/4 tsp ground black pepper

Flavor Additions

  • 2 tbsp brown sugar
  • 2 tbsp balsamic vinegar

Instructions

  1. Prepare the pan: In a large non-stick pan over medium heat, add 1 tablespoon of butter and 1 tablespoon of olive oil. Stir gently as the butter melts, creating an even fat base for cooking the onions.
  2. Initial frying: Add the sliced onions to the pan. Fry for 15 to 20 minutes, stirring occasionally, until the onions begin to soften. Be careful to adjust the heat if the onions start to brown or char; this stage is only meant to soften them and release moisture. Season with 3/4 teaspoon salt and 1/4 teaspoon ground black pepper to enhance flavor.
  3. Start caramelizing: Reduce the heat to low-medium and continue cooking the onions gently for another 20 minutes, stirring frequently. During this period, the onions will start turning a golden color. Avoid burning or crisping the onions by regulating the heat carefully.
  4. Add sweetness and depth: Stir in 2 tablespoons of balsamic vinegar and 2 tablespoons of brown sugar. These ingredients help deepen the flavor and accelerate the caramelization process.
  5. Finish caramelizing: Lower the heat to low and continue to gently fry the onions until they become a deeper golden-brown with a sticky, soft, and gooey texture. This may take an additional 10 to 15 minutes. Ensure to stir often to prevent burning and achieve an even caramelization.
  6. Serve: Once fully caramelized, remove from heat and use immediately as a topping or ingredient, or store for later use.

Notes

  • Use a large non-stick pan to prevent sticking and ensure even cooking.
  • Be patient during the cooking process; low and slow heat is essential for proper caramelization.
  • If onions begin to crisp or char, lower the heat immediately to avoid bitterness.
  • You can use any type of onion, but sweet or yellow onions tend to caramelize more naturally.
  • Store leftover caramelized onions in an airtight container in the refrigerator for up to one week.
