Preheat oven to 450 degrees Fahrenheit. Line two baking sheets with foil and brush with three tablespoons oil each. Set aside.

Place 1/4 cup flour in a shallow dish. In a separate bowl, whisk together buttermilk and egg. Add remaining flour, salt and pepper, and mix vigorously until smooth. Set aside. Place the potato chip crumbs in a separate bowl.

Working one at a time, dredge each onion ring in the flour, shaking off any excess. Dip into the buttermilk mixture and then coat thoroughly in potato chip crumbs. Place on baking sheets.

Bake until golden brown, about seven to eight minutes per side. Drain on a paper towel and serve with Broccoli Cheddar Dip (recipe follows).

Bring a large saucepan of water to a boil over high heat. Add broccoli and cook for one minute. Drain immediately and rinse under cold water. Pat dry. Transfer to a food processor and add scallions and garlic. Pulse until smooth. Transfer to a medium bowl.

In the same processor, combine cheddar and cream cheeses. Process until smooth. Return the broccoli mixture to the food processor. Add yogurt and pepper, and pulse until blended. Transfer to a large covered container and refrigerate until ready to serve.

Serve with the Oven-Fried Onion Rings.
