FAQ
Are sour cream and onion chips dairy-free?
Most commercial varieties contain dairy derivatives like whey, buttermilk, or cheese powder, so they are not dairy-free. Always check the ingredient list for specific allergens.
Why are they so high in fat?
The potato slices are deep-fried in oil, which is absorbed during cooking. The seasoning blend also often contains oils and dairy powders that contribute to the total fat content.
Can I make a healthier version at home?
Yes. You can bake thin potato slices with a light coating of oil, then toss with a homemade seasoning mix of dried onion, garlic powder, dried dill, and a sprinkle of nutritional yeast or powdered buttermilk for a tangy flavor with less fat.
