Start off by preparing your dredging, dipping and coating station. You will need 3 large Ziploc bags. You can use 3 mixing bowls but Ziploc bags allows for easier clean up. In the first bag, prepare the flour mixture by combining flour, cornstarch, paprika, salt, pepper, garlic powder.
½ cup All-purpose flour, 1 tablespoon Cornstarch, 1 teaspoon Paprika, 1 teaspoon Salt, ½ teaspoon Pepper, 1 teaspoon Garlic powder
In the second Ziploc bag, mix together buttermilk and egg.
1 cup Buttermilk, 1 Egg
In the third Ziploc bag, add panko breadcrumbs.
1 cup Panko bread crumbs
Add the onion rings in the first bag of the flour mixture. Dredge all the onion rings until they are fully coated.
1 Onion
Then, dip each onion ring in in the the buttermilk mixture.
Finally, coat each individual onion ring in the breadcrumbs until fully coated.
Set aside on a sheet of parchment paper for about 10 minutes. This will allow the coating to become tacky and stick to the onions and not fall off during frying.
While the coated onions are resting, heat oil in a large frying pan over medium-high heat until you reach a temperature of 375 degrees F.
Oil
Place a few prepared onions in hot oil without crowding the pan.
Fry for 2-3 minutes. Turn over once halfway for even frying and until rings are golden brown and crispy.
Use a slotted spoon to remove them from oil and place them on a large tray, lined with paper towels to absorb excess oil. This should take 2-3 minutes.
Serve immediately with ketchup or sriracha mayo or any dipping sauce of your choice and enjoy.
