Do you need sugar to caramelize onions? ›

You'll see some people add sugar to the recipe, which is done to speed it up. Doing this is caramelising the sugar, not the onion. The onions get plenty sweet enough on their own if you take your time with it. From a health perspective it's much better not to add extra sugar.

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. Ham, mayo, and caramelized onions on some country bread?

Put the onions in the bowl with the fat or butter. Cover the bowl and microwave for 10 minutes on high. Take off the cover, and stir the onions--there should be good bit of liquid in the bowl. Microwave (uncovered) for approximately 10 more minutes, but keep an eye on it.

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.

So using baking soda will speed up the process. But you have to be careful. If you add too much, it will impact the flavor. Different recipes recommend anywhere from ⅛ to ¼ teaspoon per pound of onions (aka about 3 large onions).

Tip: use apple cider vinegar for white and yellow onions and balsamic vinegar for red onions. Tip: the vinegar serves to deglaze the pan, adds acidity, and brings this recipe together by boosting the tangy and savory flavors of the caramelized onions. If the onions stick to the pan, that's fine.

The first phase of the process is softening the onions so that they collapse into a tender mass while releasing a good deal of their liquid. 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.

When you add baking soda during cooking it changes the pH which increases the Maillard reaction causing the onions to brown more quickly. The higher pH also causes the onions to soften more quickly, which we cover below when we discuss the texture.

While there are many plants you want to grow near onions, there are a few that should definitely be avoided. Onions should not be planted with peas, beans, asparagus, or sage. Onions can stunt the growth of these crops and also negatively affect their flavor.

Onions make great planting companions due to their ability to improve the flavor of their companion plants, as well as deter pests like aphids, Japanese beetles, and rabbits. However peas, pole beans, bush beans, and asparagus don't grow well when planted near onions.

What is the best fat to caramelize onions with? ›

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.

"Arcing," according to the Canadian Food Inspection Agency, usually happens with foods that contain high amounts of minerals, including iron, magnesium, and selenium. Since those minerals act like "tiny pieces of metal," microwaves bounce off them just like they would a fork, causing the sparking effect.

On the other hand, you can not caramelize onions for too long – they will be bitter. You need to cook the onions for 45-60 minutes – they will be soft and light brown in color. The onions are done and ready to use in any recipe that calls for caramelized onions!

You may be cooking them on too high a heat, leading them to caramelize before all the liquid they release has evaporated. Try lowering the heat and giving them more time. Some onions are wetter than others, so you need to keep an eye on them and see how much liquid they release.

Not cooking the onions long enough.

→ Follow this tip: Cook times will vary depending on the number of onions you're cooking and the type of onion (its sugar content and age), but plan to cook caramelized onions for 40 to 50 minutes (at least) until they have a dark-brown, rich color.

You don't want to slice them too thin or they'll cook too fast which could cause them to burn. You'll also want to start out with fat. I choose oil and butter. Butter gives it a good flavor and helps with the caramelization and the oil helps the butter not to brown too fast.

When you add baking soda during cooking it changes the pH which increases the Maillard reaction causing the onions to brown more quickly. The higher pH also causes the onions to soften more quickly, which we cover below when we discuss the texture.
