What is the trick to caramelizing onions quickly? ›

Secret #1: Water is Your Friend

So adding water and covering the skillet causes the raw onions to wilt faster and more evenly as the water turns to steam. Then, uncover the skillet and begin a process of pressing the softened onions into the bottom and sides of the skillet for maximum contact—and maximum browning.

Caramelized onions are not synonymous with grilled onions. Both have their place and grilled onions can be delicious, but grilling is about high heat and caramelization happens slowly over low heat.

Onions have a unique chemistry with molecules that contain a whole lot of sulphuric compounds. Sulphur is responsible for those pesky tears that pop up anytime you chop an onion, but it is also responsible for flavor and odor. The scientific name for this group of compounds is thiosulfinates.

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.

You can use either oil or butter to caramelize onions — but ideally, you use a combination of both! I like to use olive oil, and this cooking fat tolerates heat particularly well. Meanwhile, butter adds a distinctly rich flavor to the caramelized onions.

An onion's natural acidity and fluids can loosen dirt, stuck-on food, and grease, and have your grill looking nearly new in minutes. The natural juices also have antibacterial properties that sanitize the grates.

The oils from the onion can discourage food from clinging to the grate. “It creates a nice film on the grill that prevents it from sticking,” Lopez explains. “So it's not only cleaning but it's also creating a nonstick surface.” So, next time you're preparing to grill, make sure you're stocked up on onions.

Worried about onions falling apart or having trouble turning them? Try these ideas: Cover the grill grates with tinfoil and poke small holes in the foil to allow heat through. Run wooden or metal skewers through each slice or wedge.

Best Onion for Grilling

You can cook any onion you prefer on a grill, but my personal preference is a large, sweet onion like the Vidalia onion. These taste amazing when grilled, and they stay sweet and crisp with an added caramelization when grilled. If you can't get a Vidalia onion, any other sweet onion will do.

Ever wondered what makes an onion sweet? Well, it's basically how much water is in it. Onions contain roughly 90% water. Sweetness in onions is another way of saying that they lack pungency and are relatively mild.

How to remove bitterness from onions? ›

After you have cut your onions, try putting them in cold water. Soak them for at least 15 minutes (longer is even more beneficial), properly drain, and eat away! Submerging them in cold water takes away that intense, sharp bite from the raw onion.

Step 2: Cover (Optional, But It Speeds Things Up)

If you cover the pan, you'll trap steam, which will speed up their softening, heat them more quickly, and help release their liquid more quickly. Lift the lid a few times during this stage to give them a stir and make sure nothing is browning yet.

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.

It's possible that you aren't adding enough fat to the pan at first, and that your onions are sticking. That could be a problem, too. If you're way overly cautious and the flame is very, very low, it could also take a lot longer than 90 minutes, though the flavor will probably also be terrific.
