Ingredients
Gather these simple ingredients to make your own delicious caramelized onions:
For the Caramelized Onions
- 2 tablespoons olive oil
- 3 onions (medium or large, sliced)
- pinch of salt

How to Make Caramelized Onions
Step 1: Heat the Oil
Heat 2 tablespoons olive oil on high heat in a large skillet. Once heated, add sliced onions.
Step 2: Sauté on High Heat
Cook on high heat for about 10 minutes. Stir constantly using your spatula. The goal is for the onions to start browning without burning—it’s okay if a few edges get dark.
Step 3: Reduce Heat and Add Salt
Reduce heat to medium and continue cooking the onions for another 10 minutes. Keep stirring as they brown further. At this point, sprinkle just a pinch of salt over the onions.
Step 4: Final Cooking Phase
Continue cooking for another 10 minutes on medium or low heat. Stir occasionally to prevent sticking or burning. If needed, add a little water if they begin to stick too much. By now, you should have cooked the onions for a total of 30 minutes.
Step 5: Deglaze with Balsamic Vinegar
Remove from heat and sprinkle with balsamic vinegar. Use your spatula to mix the onion mixture well while scraping the bottom of the pan. Coat all the onions evenly with the balsamic vinegar.
Enjoy your beautifully caramelized onions!

Common Mistakes to Avoid
When making caramelized onions, it’s easy to make mistakes that can affect the flavor and texture. Here are common pitfalls and how to avoid them.
- Rushing the process: Caramelizing onions takes time. If you cook them on high heat, they may burn instead of caramelizing. Stick to medium or low heat for the best results.
- Not stirring enough: Onions need regular stirring to ensure even cooking. If you forget to stir, some onions may burn while others remain raw.
- Using the wrong type of onion: Sweet onions, like Vidalia or Walla Walla, are ideal for caramelizing. Using strong-flavored or bitter onions can ruin the dish.
- Overcrowding the pan: Cooking too many onions at once can lead to steaming rather than caramelizing. Use a large skillet and work in batches if necessary.
- Skipping salt: Adding a pinch of salt helps draw out moisture from the onions, aiding in the caramelization process. Don’t forget this step for better flavor!
- Neglecting deglazing: Failing to deglaze with balsamic vinegar or broth at the end means missing out on rich flavors stuck to the pan. Make sure to scrape those bits up!
