No matter how finely you mince, you won't get close to what's on those drive-thru burgers. Instead, head to the supermarket spice aisle and pick up some dehydrated white onions.
Former McDonald's corporate chef Mike Haracz recently took to TikTok to spill the beans on how to make the itty-bitty onions at home, and he isn’t the first to do so.
Another worker shared the same information on TikTok a couple of years ago, including that the rehydrated onions are soaked overnight and then put in shakers after they’re drained.
