Can Babies Eat Onion?

Yes, babies can eat onions only after six months of age after you have started them on solids and semi-solids (1). Since onions have varied flavours, from sweet to sulfuric, which can be extreme for little ones, it is better not to introduce them straight plain but by mixing them with other foods to add flavour, such as in soups or purees. Please refrain from feeding raw onion to your baby as it could be difficult to digest and may cause bloating and other digestive issues due to exposure to germs (2).

Toddlers can have grilled, roasted, or baked onions, and as they grow more, they can have more varieties of onions like onion rings. Feeding raw onion to children should be avoided until they are above one year old to give them time to develop immunity and digestion systems better.

How to Choose and Store Onion for Baby Foods?

Pungent onions and shallots are the best when you consider their health benefits, but babies have sensitive tongues, so it is better to choose sweeter varieties. Green onions are good for baby teething. Make sure to choose onions which are papery and dry on the outside and don’t feel soft. At home, you can store them in a hanging basket so that air can circulate around them. Avoid cutting and storing or freezing onions as they lose their nutritional value.

Important Tips to Remember While Preparing and Cooking Onion for Your Baby

While preparing onions for your baby, always remember that the healthy parts of the onion are in its outer layers. So be careful to just take out the papery skin and not the first few layers as well just because it’s easier. Here are some tips to peel an onion:

ADVERTISEMENT

  • Place the onion in the freezer 30 minutes before cutting it.
  • Chop the entire onion and leave the root for the last. It releases the most gas.
  • Chop onions while aiming a fan at your face
  • Use a sharp knife. The theory goes that this lessens damage to the onion’s cells, releasing less gas.
  • You can cut onions under running water, but this can make them mushy and cause some nutrient loss.

Below are tips for cooking onions for your baby:

ADVERTISEMENT

  • Sauté chopped onions over low heat in some olive oil or any vegetable oil till they become golden and tender.
  • Cut them into wedges and roast at 350 deg F for 50 minutes to bring out their sweet flavour.
  • Onions can add flavour to rice as well. Saute them in homemade stock and mix them with barley or rice.
  • You can use onions as stock for your baby’s soups and stews as well.
