What can I use caramelized onions for? ›

We love caramelized onions for their deep, savory-sweet flavor. Try them atop sandwiches, tossed into salads, baked in tarts, and more in these recipes.

While you can start the cooking process at medium heat, low and slow is the name of the game when it comes to caramelizing onions. Once your onions begin to soften and take on a golden hue, you'll want to reduce the heat from medium to medium-low or even low for the remainder of the cooking process.

Caramelized onions are delicious and healthy, and their properties and benefits are widely recognized. They have purifying, disinfecting and anti-inflammatory properties and, as they are rich in vitamins A, B6, C, iron and potassium, they stand out as a nutritious food that is recommended in the daily diet.

Sautéing vs caramelizing

Sautéing is about softening and lightly flavoring the onions, while caramelizing is about developing a rich, sweet complexity. Unfortunately, you can't swap one out for the other without changing the flavor profile of your dish.

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.

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.

You can caramelize any kind of onion, but yellow or Spanish onions tend to offer the most balanced-sweet-savory flavor profile and are the most versatile for different dishes. Sweet onions, such as Vidalia or Walla Walla work too, but keep in mind that their flavor will become even sweeter once caramelized.

The point of caramelizing is the chemical reaction that takes place with lower heat over a long period of time. Long time is kind of the point. You can speed this up with chemical means tho - adding a base - usually a pinch of baking soda - can cut the time in half.

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.

Onions are hard to digest largely because they contain fructans, which are not absorbed well in the small intestine. In fact, as fructans ferment, they can cause a great deal of digestive distress in the form of bloating, gas and diarrhea.

Why do you add sugar to caramelize onions? ›

If you need to caramelize onions quickly, adding sugar or a pinch of baking soda (to raise the pH level and help them brown quicker) can help to speed up the caramelization process but truly they aren't a dish that cooks up quickly. If using baking soda I'd suggest about 1/4 tsp per pound of raw onions.

Caramelized onions can add flavor and nutrition to a variety of dishes, such as soups, stews, sandwiches, and omelets. It's also important to remember that it's okay to enjoy caramelized onions in moderation as part of a balanced diet.

If you pack too many onions into your pan, they'll steam and produce water.

If you have enough oil, then as you fry the onions they will get dry and crispy, but you should have seen the nice juicy stage before that. Our guess then is that your are using too little oil. For 280g of chopped onions use 2 tablespoons of oil. It takes close to 15 minutes to get the caramel color.

But compared to most vegetables, onions are naturally sweet. The caramelization process takes advantage of those natural sugars to create intense and unforgettable flavors. These onions can then be used in a recipe in a variety of ways – always providing a complex sweet, savory, rich base for your dish.

At work we use yellow onions seasoned with salt and a little sugar. They take on a deep brown color and medium sweet flavor with a tiny bit of onion bite at the end. I like to use red onions at home because they taste better raw. I find that they are a little less “oniony” than yellow when caramelized.

It takes time, probably a solid 45 minutes, for the onions' sugars to caramelize. If your heat is too high, the onions will burn.

Consuming burnt onions is generally not harmful to most people, but it may not be very pleasant to eat as the burnt taste can be bitter and unpleasant.
