Ok, so you can't actually eat onion skin.
But there are other ways to access those nutrients.
Like apple skin and mango skin, the outside of an onion's skin contains quercetin.
Although the skin is not directly edible, you can draw out some of those powerful nutrients by adding it to stock.
Onion's distinct aroma and sweetness comes from their high level of antioxidants.
They're a great way to add flavor without sending the sodium level of a dish skyrocketing.
