Classic potato crisps are thin, golden slices of potato fried until crispy and salty. They shatter between your teeth and taste purely of potato and oil. The secret is slicing thin, drying the slices well, and frying at a steady temperature so they crisp without browning too dark.
Ingredients for Classic Potato Crisps
Russet potatoes are starchy and slice cleanly into uniform, thin rounds that crisp evenly. Vegetable oil fries them to a golden color without adding flavor. Salt brings out the potato taste and makes them addictive.
Why This Classic Potato Crisps Works
Russet potatoes have less water than waxy varieties, so they dry faster and fry crispier. When you slice them thin and soak out the starch in cold water, the exterior fries to a hard shell while the inside stays tender instead of becoming tough.
Frying at 325°F (163°C) cooks the potato through without burning the outside. The oil must stay at this temperature throughout, so you fry in small batches and wait for the oil to come back up between them. If you crowd the pan, the temperature drops and the crisps turn greasy.
Mistakes To Avoid
Skipping the soak leaves starch on the surface, which absorbs oil and makes the crisps greasy and soft instead of crispy. Even a quick rinse and drain is better than nothing, but 30 minutes in cold water is the standard.
Frying at too high a temperature burns the outside before the inside is crisp, and you get dark, bitter crisps. At too low a temperature, they absorb oil and turn limp. A clip-on thermometer on the pot keeps the oil steady.
Crowding the pan drops the oil temperature and steams the crisps instead of frying them. Fry only as many slices as fit in a single layer without touching, usually a handful at a time.
Storing warm crisps in a sealed container traps steam and makes them soft. Cool them on paper towels first, then store them in an airtight container at room temperature for up to one day.

Ingredients
- 2 pounds russet potatoes
- Vegetable oil for frying, about 6 cups
- Salt to taste
Step-by-step Instructions
- Scrub potatoes and peel them. Slice thin on a mandoline or with a sharp knife into rounds about 1/16 inch thick.
- Place slices in a bowl of cold water and soak for 30 minutes to remove starch. Drain and pat completely dry with paper towels.
- Pour oil into a large heavy pot until it is 2 inches deep. Never fill the pot more than halfway. Heat to 325°F (163°C) on a clip-on thermometer.
- Fry a small handful of potato slices, about 10 to 12, until they turn golden and no longer bubble, 3 to 4 minutes. Remove with a slotted spoon and drain on paper towels.
- Let oil return to 325°F (163°C) before frying the next batch. Repeat until all potatoes are fried.
- Season warm crisps with salt while they are still on the paper towels. Cool completely before storing or serving.
Frequently Asked Questions
Can I make these ahead?
Fry them up to 1 day ahead and store them in an airtight container at room temperature. They will soften slightly but remain crispy. Do not refrigerate them, as cold makes them absorb moisture and go limp.
Can I use a different potato?
Russets work best because they are starchy and slice cleanly. Waxy potatoes like red or fingerling have more water and will not crisp the same way.
How do I hold these for a party?
Cool crisps completely, then store them in an airtight container at room temperature until serving time. Do not leave them out at room temperature for more than 2 hours. You can reheat them in a 300°F (150°C) oven for 5 minutes to restore crispness just before serving.
Serving Ideas for Classic Potato Crisps
Serve them plain in a bowl as a snack with drinks. Pile them on a plate alongside roasted fish or chicken for a simple side. Pair them with dips like sour cream mixed with fresh herbs, or with vinegar for dipping. At a party, leave them in an airtight container and set them out just before guests arrive so they stay crispy.
