Line a microwave tray with a piece of parchment paper and spread the onions on it in a thin, even layer. Microwave on medium power for about 20 minutes, or until the onions are completely dried out. Let cool to room temperature.
Grind the onions in a coffee or spice grinder until they resemble the flakes of kosher salt. Store in a covered plastic container.
