Homemade potato chips are salty, crispy, golden-brown morsels you won't want to stop eating! Enjoy them with your favorite dip or alongside a toasted sandwich.
Fill a large bowl with ice water. Using a mandoline, thinly slice the potatoes crosswise. (The slices should be thin enough to see through, about 1/8-inch to 1/16-inch thick.) Transfer the potato slices to ice water and let soak for 10 minutes.
Drain the potato slices and arrange them in a single layer on a paper towel lined baking sheet. Lay another layer of paper towels on top and pat the potatoes dry.
Fill a large Dutch oven with enough oil to be 2-inches deep. Place over medium-high, add a deep-fry thermometer, and heat until the oil reaches 325°F. Place a wire rack inside a baking sheet and line with paper towels.
Working in batches, fry the dried potatoes, stirring occasionally, until light golden brown, about 3 minutes. (I fry a generous handful of potatoes at a time for a total of five batches.) Transfer the chips using a spider or slotted spoon to the paper towels, and immediately sprinkle with salt to taste. Let cool for 5 minutes before serving.
Notes
Use a mandoline to slice the potatoes. A mandoline will slice the potatoes thinly and evenly. The slices should be thin enough to see through, about ¼-inch to ½-inch in thickness.
Soak the sliced potatoes in an ice bath. This removes the excess starch from the potatoes for crispy homemade potato chips.
Pat the potatoes dry. Removing excess moisture is another key step for the crispiest chips.
Use a deep-fry thermometer to measure the temperature of the oil. This is the most accurate way to get the oil to the perfect frying temperature of 325°F.
Do not overcrowd chips while frying. If your chips are taking more than 4 minutes to turn golden brown, try frying in smaller batches.
Lay the chips in a single layer to drain off excess oil. Piling up the chips just leads to soggy potato chips, and no one wants that!
Season the chips immediately after removing them from the oil. This will help the salt stick to the chips.
