About this guide:
This guide lists how many slices and how many cups of rough-chopped, medium-diced or finely diced (minced) onion you get from different-sized whole onions. The tables below allow you to easily calculate how many onions of what size you need to get however many cups of chopped onion you need.
Different onion cuts:
The tables below list amounts for four different cuts of onion:
- sliced
- rough-chopped
- medium-diced
- finely diced (minced)
Sliced onion:
You can slice an onion to get onion rings. (This is a great cut for caramelizing onions (or shallots), like for this gourmet grilled cheese, for example.) The number of slices listed in the tables below is for ⅛ inch-thick slices.
Rough-chopped onion:
The amounts for rough-chopped onions listed in the tables below are for chunks of onion that measure about ½ inch per side.
Medium-diced onion:
The amounts for medium-diced onions listed in the tables below are for chunks of onion that measure about ¼ inch per side.
Finely diced onion (minced):
The amounts for finely diced onions listed in the tables below are for chunks of onion that measure about ⅛ inch per side.
