How do you caramelize onions?
Caramelized onions work beautifully when piled on patty melts, cheesesteaks, sausage heros, or even just a piece of crispy bread with goat cheese. They work well on cold cuts too.
Do you add water to caramelized onions?

Deglazing the pan with water while cooking over higher heat is one of the only ways to speed up caramelized onions without sacrificing too much quality. You can deglaze as much as necessary while keeping the flame higher to brown the onions faster; the key is to add the water every time the onions threaten to burn.
How do you tell when caramelized onions are done?
Let your nose and your tastebuds be your judge — when you can’t resist eating them straight out of the pan, they’re done. It can take up to an hour to caramelize the onions, and if anyone tells you differently they’re lying.

Why does caramelizing onions take so long?
Before onions can caramelize, enough moisture has to evaporate out of the pan for the cooking surface to climb above 212 degrees. That alone takes a while, and once it happens, you’re still committed to stirring and scraping so the onions’ natural sugars break down evenly.
Do you put lid on when caramelizing onions?
The secret to making them is patience. It can take up to 40 minutes for the onions to become deeply browned, but the result is worth every minute. Covering the skillet at the beginning helps the onions to soften and release their liquid, then slowly cooking them uncovered makes them meltingly soft and sweet.
How often should I stir caramelized onions?
every 5 to 6 minutes
Fold. Fold onions with a spatula, scraping bottom of pan to ensure they don’t stick or scorch. Cook, stirring every 5 to 6 minutes and reducing heat as necessary to maintain a gentle simmer, until liquid has evaporated, about 35 minutes.
