When to Salt Caramelized Onions?

When you salt the onions at the beginning, it will take longer to achieve browning because of the extra water it draws out, but ultimately, your onions will have a much better flavor and will brown more evenly if you add the salt at the beginning of the cooking process. Cook the onions over medium low heat.

Should you salt onions when sweating?

The heat and the salt will draw the moisture out of the onions, thus 'sweating' them. Onions will also start to glisten and look wet (ie, "sweaty"!). It sometimes helps to cover the pan at this stage to encourage the release of moisture, but be sure you check your onions and stir them frequently.

Do you cover the pan when caramelizing onions?

They're surprisingly tricky to make. They take time to slowly brown and caramelize. ... Just cover the bottom of your pan for jammy, soft caramelized onions, or add a little more for more structured, slightly charred caramelized onions. The more fat in the pan, the more the onions will fry rather than soften.
