You can can onions that have been cut to 1" diameter or less. So Easy to Preserve (a University of Georgia Extension publication) provides the canning recipe:
After cutting to 1", wash, then cover with boiling water & bring to a boil. Boil 5 minutes. Pack the onions into hot jars (pints or Quarts). Add 1/2 tsp salt to pints, 1 tsp to quarts (optional). Fill jar to within 1" from top with boiling water. Remove air bubbles. Wipe jar rims, adjust lids and process:
Dial gauge pressure canner @ 11 pounds pressure or for a Weighted gauge it is at 10 pounds pressure.
Process both pints & quarts for 40 minutes (can choose smaller jars if desired but must use the 40-minute processing time as no time is given for smaller jars).
