Why accurate onion measurements matter in air frying

Air fryers cook food quickly using circulating hot air, which means ingredient quantities directly affect cooking times and results.

Types of onions and their weights

Different onion varieties have slightly different densities. A 125g portion of red onion might appear slightly larger in volume than white onion due to its higher water content. For air frying, all types work well, but sweeter onions like shallots (about 5-6 shallots to make 125g) caramelise beautifully.

Storing measured onions for air fryer meals

After measuring out 125g of onion, you might have leftovers. Store chopped onions in an airtight container in the fridge for up to 3 days. For longer storage, freeze measured portions - 125g bags work perfectly for future air fryer recipes. Visit our cleaning guide to remove onion odours from your appliance.

Pre-measured 125g portions of frozen onions can go straight into the air fryer, though you may need to add 1-2 minutes to cooking time. The water content in frozen onions helps create steam, which can be beneficial for certain dishes like air-fried fajitas or stir-fries.
