1. On a cutting board, remove the stem end of the onion and trim the root but leave it otherwise  intact. Peel away the outer skin. 
   
   
2. Position the onion in the center of your cutting board with the stem end facing your knife and cut slices of the desired thickness.
   
   
3. Stop when you reach the root end and discard it. You can now separate the onion slices into rings
   
   TIP: If you’re uncomfortable slicing the round onion, hold the onion so the stem end is facing you, then cut away a ¼” inch piece from the side of the onion so that is lays flat on the cutting board.
