1. Preheat oven to 450 degrees F.

2. Combine 1/4 cup flour, salt, black pepper, and cayenne in a bowl.

3. In another bowl combine the buttermilk, egg, and additional flour, whisking until a smooth batter is formed.

4. In a third bowl, place the crushed potato chips.

5. Prepare the onion rings by first dipping a ring into the seasoned flour, then into the batter (let the excess batter drip off), and then coat with the crushed potato chips. As you finish the rings, place them on a large plate. Repeat with all the rings.

6. Cover a baking sheet with parchment paper. Drizzle the vegetable oil on the parchment-lined sheet and place in the oven for 8 minutes. Carefully remove the baking sheet from the oven and tilt to evenly coat with oil.

7. Working quickly, place your onion rings on the baking sheet and return to oven. Bake for 8 minutes, then flip onion rings and bake for an additional 6-8 minutes, or until golden brown.

8. While baking, prepare your dipping sauce!
