While packaged potato chips are typically deep-fried in oil, you can take the healthier route and make them at home in the oven. A mandolin slicer makes it easy to cut the potatoes to the desired thickness of about 1/8 inch.

Prepping the Potatoes

Choose large potatoes to yield multiple servings for your family and friends. Scrub the potatoes under warm running water to remove any surface dirt. Cut the potatoes in half to create a flat surface. Slide the flat side of the potato across the blade of the mandolin slicer to create thin, symmetrical potato slices. Toss the potato slices with a few tablespoons of olive oil and sprinkle them with salt and pepper.

Oven Setting and Cook Time

Heat your oven to 400 degrees Fahrenheit. Line a baking sheet with aluminum foil and spray it with cooking spray. Transfer the potato slices onto the baking sheet and space them about 1/4 inch apart. Bake the potato chips for around 30 minutes or until they turn golden brown. Rotate the baking sheet halfway through so the chips cook evenly.

Serving Suggestions

Homemade potato chips offer endless possibilities, because you can add various ingredients to enhance the flavor. Try sprinkling them with some Parmesan cheese or kick up the heat with a few pinches of cayenne pepper. Chop some fresh rosemary to sprinkle on top for a flavorful and aromatic twist.



When pairing homemade chips with hearty appetizers such as sausage or spinach dip, cut the potatoes lengthwise to create more surface area for dipping. You can also adjust the mandolin to cut thicker potato slices, as this helps prevent broken chips, and peel the potatoes if you prefer chips without the skin.


Russet and Yukon gold varieties work best for homemade potato chips.
