For a healthier take on classic onion dip, try this version that's made with Greek yogurt. Traditionally served with greasy potato chips, this recipe calls for homemade baked chips — at a fraction of the fat. These crisp, cracked-pepper chips are worth the cook time, and the dip can be made the night before your event.
Preheat oven to 450°F. Toss sliced potatoes in a large bowl with the olive oil and pepper until well-coated. Arrange potato slices in 1 layer on 2 cookie sheets.
Bake for 20-25 minutes until chips are crisp and lightly browned. Remove from oven, season with salt, and cool.
To make the dip, heat oil over medium heat and add onions and scallion whites. Cook, stirring often, until golden brown and soft, about 10 minutes. Remove from heat and allow to cool.
Combine onions with Greek yogurt, onion powder, garlic powder, salt, pepper, and scallion greens. Stir well to incorporate.
Chill for 1 hour to let flavors meld. Serve with chips.
