Ingredients
Scale
Main Ingredients:
- 4 large yellow onions
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter
Supporting Ingredients:
- 1 pinch salt
Flavor Enhancers (Optional):
- 1 pinch sugar
- 1 splash balsamic vinegar
Instructions
- Slice 4–5 large onions into thin ⅛- to ¼-inch strips using a sharp knife. Keep slices consistent for even cooking.
- Select a large stainless steel or cast-iron skillet. Add 2 tablespoons of olive oil or butter at medium heat until shimmering.
- Drop all sliced onions into the hot pan. Spread them evenly across the surface, allowing them to start softening.
- Reduce heat to medium-low after 5 minutes. Sprinkle a pinch of salt over the onions to help draw out moisture.
- Stir onions every 3–4 minutes, ensuring they cook evenly and do not burn. Watch for gradual color transformation from white to golden.
- After 20–25 minutes, onions will begin turning deep golden brown. If pan looks dry, add 1–2 tablespoons of water to prevent sticking.
- Continue cooking for another 10–15 minutes, stirring frequently. Your onions should reach a rich caramel color and develop a sweet, mellow flavor.
- Optional: Add a splash of balsamic vinegar in the final 2 minutes for extra depth and complexity.
- Remove from heat when onions are deeply caramelized and soft, approximately 35–40 minutes total cooking time.
Notes
- Take time when caramelizing onions, as rushing will prevent deep flavor development and proper browning.
- Use a heavy-bottomed pan to ensure even heat distribution and prevent burning during the long cooking process.
- Slice onions consistently to help them cook evenly, aiming for ⅛- to ¼-inch thick pieces for best texture.
- Salt and optional sugar can enhance the natural sweetness and help break down the onions more quickly.
