Can you use red onion in soup?

In this article, we will answer the question “Can you use red onion in soup?”, how to store onions, can you freeze onions, and how to use yellow, red, and white onions.

Can you use red onion in soup?

Yes, you can use red onion in the soup. It makes for an excellent substitute for white or yelp onions. Their color differs but the flavor profile has mild nuances. Due to a milder taste than the other two types of onions, red onions are preferred to be used raw.

Moreover, raw onion looks more attractive in pickles and salads because they bring a pop of color. If the recipe calls for caramelizing the onion, do not hesitate to use red onion.

Red onion caramelized just like the yellow and white onions but the caramel color is just not as striking and noticeable. Raw slices of red onions work great in sandwiches, burgers, salads, and pickles. You can also grill or roast your red onions or use them in salsas, and chutneys.

How to store onions?

The general rule of thumb is to keep the onions somewhere cool, dark, and dry. Make sure the storage area is well-ventilated. Moisture makes the onions go moldy so you should never keep the onions anywhere close to the sink.

Exposure to heat or sunlight makes the onions sprout which is more of a quality issue than a safety. Because onion sprouts can be used in different recipes.

Keep the onions in a basket or a wide-mouthed bowl so that the onion pile is not too high. Because the piling pressure causes the onions at the bottom to go mushy. 

Note that the storage instructions given above apply to whole onions. When it comes to cut or sliced onions, you better store them in the fridge. Transfer the cut onions to an air-tight container to prevent the pungent smell of the onions from escaping into the fridge. 

Can you freeze onions?

Yes, you can freeze onions. Remove the skin from the whole onions. Rinse the onions thoroughly under cold running water to get rid of the surface dust and dirt. 

Then coarsely cut the onions using a sharp knife. Transfer the cut onions to a freezer bag. Squeeze out the excess air from the bag and chuck it into the freezer.

Make sure to lay the freezer bag flat in the freezer until the onions have completely frozen. Alternatively, you can flash freeze the onions before bagging them.

Just spread the cut onions into a large baking tray and put the tray into the freezer. When the cut onions have frozen, transfer them to an air-tight container or a freezer bag. We recommend using a freezer bag since it is more freezer-space friendly and gets the job done.

How to use yellow onions?

Yellow onions, which also go by the name brown onions, are best used after grilling, sauteeing, roasting, or caramelizing. Yellow onions are less sharp as compared to red onions. 

However, you will find the taste of the yellow onions quite sharp if you eat them raw or simply because you are not used to them. In this case, you can try a milder alternative, that is, Spanish onions.

Due to high starch content, yellow onions do not soften easily. Therefore, you might want to cook them longer or on a high flame.

How to use red onions?

Red onions are mostly seen in Greek salad or kachumber. A bed of red onions is made in the baking tray for baking roast in the oven. The taste o the red onions is very pungent.

To reduce its fierceness, dump the sliced red onions in ice-cold water. Red onions are best used after grilling because of their appealing red color that does not go away even after heating or charring. The color appeal and the taste are also why red onions are a preferred choice for pickling


How to use white onions?

White onions are not as sharp as yellow or red onions. The soft texture and the mild taste make the white onions suitable for raw consumption.

Dump the sliced white onions in ice-cold water for some time. Then add to your salad bowls for a crunchy twist.
