What’s the Difference Between Caramelizing and Sautéing?

Caramelizing involves cooking onions slowly over low heat until they become soft, golden brown, and sweet, a process that can take 30 to 60 minutes. In contrast, sautéing is a quicker method that cooks onions over medium-high heat, resulting in a tender but not necessarily sweet onion. Sautéed onions retain more texture and are typically cooked for just a few minutes.

How to Make Ahead and Store the Best Caramelized Onions

To make ahead, cook your onions according to the recipe and let them cool completely. Transfer them to an airtight container and store them in the refrigerator for up to 4 to 5 days. If you want to make a larger batch, caramelized onions can also be stored in the freezer for up to 3 months.

How to Freeze and Reheat Quick Caramelized Onions

To freeze caramelized onions, let them cool completely, then portion them into freezer-safe bags or containers. Squeeze out any excess air to prevent freezer burn. To reheat, you can thaw them in the refrigerator overnight and then heat them in a pan over low heat until warmed through. Alternatively, you can reheat them directly from frozen in a skillet, adding a splash of water or broth to help them warm up without burning.
