Why do my onions keep burning? - White and Green Round Fruits on Green Textile

Twice now, I have burned my onions while heating them in a pan. I was just trying to caramelize them, and they burned every time.

They were on medium heat, and I put olive oil at the bottom of the pan (which may or may not have been a mistake), and they just burned, sticking to the bottom with a fervor I've never seen before (except the other time I tried to heat up onions).

What am I doing wrong?



Best Answer

To clarify a little, there are several ways you can cook onions.

  1. You could be trying to get them to turn translucent. In which case, you can cook over medium heat, stirring frequently. This will take somewhere around 5 minutes. Preheating the pan isn't really required (especially if using a non-stick pan). If they start to brown, turn down the heat.

  2. You could be trying to get them to turn translucent, with brown edges. Proceed as with translucent, but make sure to preheat the pan, and also use medium-high heat (but if they get too brown, turn down the heat).

  3. You could be trying to caramelize them, turning them brown throughout. Cook them on low heat. At first, you can stir infrequently, but as they turn translucent and begin to brown, you'll have to speed up your stirring. This takes 30+ minutes.

So, if you were actually caramelizing onions, your heat was much too high.

In general, when something is browning too much (or outright burning) before the center is cooked, you need to turn down the heat or if only the pan-contact parts are browning then stir more frequently. To some extent when cooking in a pan, there is a trade-off you can make: low heat, infrequent stirring, long cooking time vs. high heat, constant stirring, quick cooking.

Answer 2

Onions have a lot of sugar in them. All they want in the world is to burn and fill your kitchen with oniony smoke.

The solution, as with all things heavy in sugar, is to turn down the heat and stir frequently.

That said- if your olive oil was extra virgin then it might have been your oil that started burning before the onions did.

Answer 3

When cooking it's important to use your eyes, ears and nose.

If the pan is at the correct heat, you can leave the onions alone for minutes at a time, just giving them an occasional stir, but your ears and nose will keep you informed. When caramelising, you should only just be able to hear the sizzling. Anything louder, and they'll probably brown too fast.

If the onions actually stick, the heat is most likely far too high. You need to get familiar with your stove to know what the correct setting is, but even then, remember your ears.
