FAQ
Frequently asked questions.
How long do sweet onions last?
Sweet onions have a higher water and sugar content than yellow onions, so they only last 1-2 weeks at room temperature or up to 4 weeks in the refrigerator.
How do I pick a good sweet onion?
Look for onions that are firm, heavy for their size, and have dry, papery skin with no visible bruising or soft spots.
Can I substitute sweet onions for yellow onions?
Yes, but sweet onions are much milder. If a recipe calls for the sharp bite of a yellow onion, sweet onions might make the dish taste flatter or sweeter.
Why do sweet onions make you cry less?
They contain less sulfur than standard onions, which is the compound responsible for the pungent odor and the gas that causes tears.
Can sweet onions be frozen?
Yes, you can freeze them chopped. However, they will lose their crisp texture and should only be used for cooked dishes like soups or stews after thawing.
Are sweet onions seasonal?
Yes, specific varieties like Vidalias are typically available from April through August, though other sweet varieties are grown year-round in different regions.
What is the best way to eat sweet onions?
They are excellent raw on burgers, in salsas, or thinly sliced in salads. They are also the preferred choice for French Onion Soup.
Are sweet onions keto-friendly?
In moderation. They have about 7-8g of carbs per 100g, which is slightly higher than some other vegetables, so track portions carefully.
