What are the best onions for caramelizing? ›

You can caramelize any kind of onion, but yellow or Spanish onions tend to offer the most balanced-sweet-savory flavor profile and are the most versatile for different dishes. Sweet onions, such as Vidalia or Walla Walla work too, but keep in mind that their flavor will become even sweeter once caramelized.

Caramelize the onions: Heat about 1 tablespoon of canola oil in a large skillet or dutch oven over medium-low heat. Once hot, add the onions and stir to coat. Let cook, stirring every 5-10 minutes, until deeply caramelized, about 1 ½ - 2 hours.

You'll see some people add sugar to the recipe, which is done to speed it up. Doing this is caramelising the sugar, not the onion. The onions get plenty sweet enough on their own if you take your time with it. From a health perspective it's much better not to add extra sugar.

Our Test Kitchen likes to use butter when caramelizing onions, as it offers the richest flavor. If you avoid dairy or don't have butter, you can caramelize onions in other fat such as margarine or olive oil. Add the onion slices. It's okay if they overlap a bit here because they'll shrink as they cook down.

Brown sugar is simply cane sugar with molasses added to it. Therefore, you are adding even MORE sugar, and more brown color, to your onions. Thus the caramelization is so much better and faster! If you don't have brown sugar, feel free to use regular cane sugar or even panela when caramelising onions.

Salting caramelized onions is like the icing on the cake. They must have salt but don't make the mistake of salting the onions too early. Instead, salt them at the very end of the recipe. Salt makes the onions release moisture which can slow down the caramelization.

Tip: use apple cider vinegar for white and yellow onions and balsamic vinegar for red onions. Tip: the vinegar serves to deglaze the pan, adds acidity, and brings this recipe together by boosting the tangy and savory flavors of the caramelized onions. If the onions stick to the pan, that's fine.

Add the onion slices and stir to coat the onions with the oil. Spread the onions out evenly over the pan and let cook, stirring occasionally. Depending on how strong your stovetop burner is you may need to reduce the heat to medium or medium low to prevent the onions from burning or drying out.

Do you need to add sugar when caramelizing? No! Onions already contain natural sugars, which is why they're so perfect for caramelizing. This process brings out those sugars to make them more prominent.
