Yes and No – Onions Can Be Sweet, Savory, Pungent at the Same Time
Onions are complex vegetables. They have many layers, both literally and figuratively. They can be sweet, savory, and pungent at the same time. This complexity makes them so interesting to cook with and eat.
When you cut into an onion, the first layer that is exposed is the papery skin. Underneath the skin is the layer of thin flesh. This layer is where the onion’s sweetness comes from.
The next layer is the layer of thick flesh, and underneath that is the layer of root. The root is what gives the onion its pungent flavor.
The amount of sweetness that you taste in onion will depend on how thick the papery skin is. The thicker the skin, the more sweet onions taste.
Is Onion Sweet By Default?
No, onions are not sweet by default. In order for them to be sweet, they need to be treated in a certain way.
Onions don’t start out sweet – they become sweet when two things happen:
- As the onion grows, the plant produces sugar and stores it in its bulb. This is how most vegetables get their sweetness.

So, is onion sweet? Yes, but it’s not always sweet. The sweetness of onion depends on how it is grown and cooked. But, for the most part, the sweeter an onion is, the more flavor it has.
