  • Peel & remove the tip from the brown onion, leaving the root intact. With the root facing up, slice next to the root to create 4 even slices around the onion in the shape of a cross. Slice in between each original slice to create 16 even-sized slices the whole way around. Flip the onion over & gently open it to create a blooming onion (see photo & video).
