French Fried Onions

  1. Start by cutting 2 large onions in half and slicing them thinly using a mandoline. Place in a bowl and add 1 cup of buttermilk, covering the onions. Let sit for 15 minutes.

  2. Drain onions and toss them in all purpose flour to coat. Once they’re nicely coated, use a fine mesh sieve to shake off the excess flour.
