Method
 

Step 1
  1. I peel the onion and cut off the top only, leaving the root intact. Then I carefully slice downward to create about 16 petals and gently separate them.

Step 2
  1. In one bowl, I mix flour, paprika, garlic powder, salt, pepper, and cayenne. In another bowl, I whisk the buttermilk and egg together.

Step 3
  1. I dip the onion into the buttermilk mixture, letting it soak into all the petals, then coat it thoroughly in the flour mixture, pressing gently so it sticks.

Step 4
  1. I heat the oil to 375°F in a deep pot. The oil needs to be hot so the onion fries crispy, not greasy.

Notes

  • I always use a sweet onion for the best flavor.
  • Keeping the oil at 375°F is key for crispiness.
  • The dipping sauce tastes even better if made a little ahead.
  • I don’t recommend microwaving leftovers because they lose crunch.
