How to Make Caramelized Onions
Step 1: Heat the Skillet
Heat 2 tablespoons of olive oil on high heat in a large skillet. Once the oil is hot, add the sliced onions. Cook on high heat for about 10 minutes, stirring constantly with a spatula. The goal is to start browning the onions without burning them.
Step 2: Add Salt and Reduce Heat
After 10 minutes, reduce the heat to medium. Continue cooking for another 10 minutes while stirring. At this stage, sprinkle a pinch of salt over the onions to enhance their flavor.
Step 3: Slow Cook for Richness
Cook the onions on medium or low heat for an additional 10 minutes. Stir occasionally to prevent sticking or burning. If they begin to stick, add a little water. By now, you should have been cooking the onions for a total of 30 minutes.
Step 4: Deglaze and Finish
Remove from heat and sprinkle a small amount of balsamic vinegar over the cooked onions to deglaze the pan. Using your spatula, mix well while scraping up any tasty bits stuck to the bottom of the pan, ensuring all onions are coated in this flavorful addition.

Common Mistakes to Avoid
Caramelizing onions can be tricky if you’re not familiar with the process. Here are some common mistakes to watch out for.
-
Overcrowding the Pan: When you add too many onions at once, they steam instead of caramelizing. Use a larger skillet or cook in batches to achieve that beautiful browning.
-
High Heat Throughout: Starting on high heat is essential, but maintaining it can lead to burnt onions. Lower the heat after the initial cooking phase to ensure even caramelization without burning.
-
Neglecting to Stir: Forgetting to stir allows some onions to burn while others remain raw. Stir frequently during cooking to promote even browning and prevent sticking.
-
Skipping the Salt: Adding salt early enhances moisture release, promoting caramelization. Don’t skip this step; a pinch of salt makes a difference!
-
Rushing the Process: Caramelization takes time. Cooking onions too quickly leads to uneven results. Be patient; allow at least 30 minutes for the best flavor.
