Red Onions – Information and Facts

Red onions are one of the most popular types of onions and can be used in a variety of dishes. They have a mild flavor, but also offer a subtle sweetness when cooked. Red onions are rich in vitamins and minerals, making them a great addition to any meal. Let’s take a look at some facts about red onions, as well as some tips on how to store and prepare them for cooking.

Nutrition Facts

When it comes to nutrition, red onions are chock-full of vitamins and minerals that help keep your body healthy. One cup (160 grams) of raw red onion contains 8% of the Recommended Daily Value (DV) for vitamin C, 8% DV for manganese, 7% DV for vitamin B6, 5% DV for potassium, 4% DV for phosphorus, 3% DV for folate, and 2% DV for calcium. They also contain small amounts of iron, zinc, magnesium, and selenium.

Storage Tips

When you buy these onions from the store or market, make sure you store them properly so that they stay fresh longer. The ideal storage temperature is between 32°F (0°C) and 40°F (4°C). You should also keep them away from direct sunlight or other sources of heat. To keep your red onions fresher longer, store them in a cool dry place with good air circulation such as a pantry or refrigerator drawer. For optimal shelf life, wrap each onion separately in paper towels before storing them in an airtight container or plastic bag.

Preparing Red Onions

Once you have the right storage method down pat it’s time to start prepping your red onion! Start by rinsing off your onion under cold running water to remove any dirt or debris. Peel off the tough outer layers until you get to the softer inner layers. These will be darker in color than the outer ones! Cut off both ends so that you have two open “rings” at either end. This allows more surface area for seasoning later on! Finally slice your onion into desired thickness – this could range from thin rings (for salads) to thicker slices (for stir-frys). Now you’re ready to cook up some delicious dishes with your freshly prepared red onion!


Red onions are a great addition to any meal because they are full of nutrition and add flavor without overpowering other ingredients. Be sure to store your red onions properly to ensure maximum freshness and shelf life; wrap each individual onion in paper towel before placing it into an airtight container or plastic bag.
