Here is my simple method for how to make perfectly caramelized onions. Use caramelized onions as pizza topping, for pasta, for onion dips and many other recipes.
How to caramelize onions
- Thinly slice 3 large onions.
- To a large skillet add 1 tablespoon olive oil on high heat. When oil is heated, add sliced onions and cook on high heat for about 10 minutes, constantly stirring with spatula. The onions should start to brown, but without burning (a couple of onions may be burnt here and there, but overall they should not be charred).
- Reduce heat to medium and continue cooking onions for 10 more minutes, continuing to stir, as onions brown even more without burning. At this point add just a pinch of salt over onions.
- Continue cooking the onions for 10 more minutes on medium or low heat, stirring occasionally to make sure onions don’t stick to the bottom of the pan or burn. Add a little bit of water if they start to stick.
- Total, by now you should have cooked onions for 30 minutes.
- Remove the pan with caramelized onions from heat and sprinkle the onions with a small amount of balsamic vinegar to deglaze the pan.
- Using spatula, stir the caramelized onions, scraping the bottom of the pan and coating onions with a pinch of balsamic vinegar you just added.
Ways to use caramelized onions
- Caramelized onions can be such a nice side kick to so many dishes: from pasta to grilled meats and hamburgers; as a topping over pizzas or a condiment in salads.
- I use caramelized onions a lot in my cooking, such as in caramelized onion and mushroom pasta and mac and cheese with bacon and caramelized onions - both recipes are delicious and highly recommended!
- The options and versatility of caramelized onions are endless! For example, have you ever tried caramelized onions in a quiche or a tart? Or, in a French onion soup? What about caramelized onion dip? The subtly sweet flavor of the caramelized onions combined with the savory is so addicting!

I love your recipes. Do you use a regular or non stick pan for this.
It doesn’t really make a difference. I think I’ve used three types of pans for caramelizing onions: stainless steel, non-stick, and cast iron.
Used this recipe to make my first caramelized onions. Simple and easy to follow. Thank you!
Fed up of trying to make something different for our main meal at night....but has to be quick & easy....cheers
I've used caramelized onions to top scrambled eggs. And to remove a single serving from the pan, a spaghetti fork is just the thing
looks yummy, i cant wait to try it!
Enjoy!
Can they be stored to be also eaten another day with a different food: chicken, fish, steaks, fajitas?
I think the brown coloring could be from the balsamic. Ingredient list says 1 T but directions say a pinch. Less I guess might keep them lighter
The onions will brown even before adding a pinch of balsamic vinegar. It's the sugars in the onions that caramelize in the process and produce this rich brown color.
Mine look so much more brown than the picture! I followed the instructions to a T. They aren't burned. Just really brown and they have cooked down a lot. Is that OK? I did get a lot of black char on the bottom of the pan, but the onions themselves aren't burned or charred much at all. Looking for some validation that I did it OK, or if I messed up! Planning to use them in one of your recipes tomorrow. Thank you.
Sounds like you did everything right! The onions will brown a lot because of the sugars in the onions that caramelize in the process and produce this rich brown color. The onions also reduce in volume tremendously as you cook them. So, yes, the caramelized onions themselves should not be burnt, they should have a rich brown color and a rich sweet flavor.
