Crispy Homemade Potato Chips

Last summer, my nephew dared me to make chips better than his favorite brand. Three hours and one oil splatter later, I realized the secret was patience and the mandoline I'd been avoiding for years. Now I can't go back to bagged chips.

My first attempt ended with slightly burnt, uneven slices and way too much salt. But watching my friends hover around the bowl, reaching for just one more, made every mistake worth troubleshooting. They disappeared before dinner even hit the table.

Ingredients

• Potatoes: Russets have the perfect starch content for crispy chips, and buying them a bit old actually helps
• Fine sea salt: Table salt won't stick properly, and Kosher salt is too chunky for delicate chips
• Vegetable oil: Sunflower or canola oil has a neutral flavor that lets the potato shine through

Instructions

Slice your potatoes:

Use a mandoline for consistently thin rounds, or practice your knife skills, aiming for paper thin slices that let light through

Rinse and dry thoroughly:

Remove excess starch by rinsing in cold water until the water runs clear, then pat completely dry with towels because water and hot oil are enemies

Heat your oil:

Bring the oil to 170°C (340°F) and use a thermometer if you have one, since the right temperature makes all the difference

Fry in small batches:

Carefully add potato slices without overcrowding the pan, and listen for the satisfying sizzle that means crisping is happening

Season immediately:

Transfer chips to paper towels to drain, then sprinkle with salt while they're hot so it actually sticks

These became my go to contribution for game nights after everyone kept asking when I'd bring them again. Something about making something so comforting from scratch feels like giving a tiny gift.

Getting the Perfect Crunch

I've learned that soaking the slices in ice water for 30 minutes before frying creates the ultimate crunch. The cold water pulls out even more starch, resulting in lighter, crisper chips that stay crispy longer.

Seasoning Beyond Salt

While plain salted chips are perfect, sometimes I toss them with smoked paprika immediately after frying. The heat from the chips helps the spices adhere, and the smoky flavor makes them feel restaurant quality.

Storage and Serving

Completely cooled chips store beautifully in an airtight container for up to three days, though they rarely last that long in my house. If they lose some crunch, a quick 5 minute bake at 175°C (350°F) brings them back to life.

• Let chips cool completely before storing or trapped steam will make them soggy
• Layer paper towels between chips if you're stacking them in a container
• Never store warm chips or you'll ruin all your hard work

Save

There's something deeply satisfying about transforming a simple potato into something so irresistibly snackable. Hope your kitchen smells as amazing as mine always does.

Your Recipe Questions Answered

→ How thin should I slice the potatoes?

Slice potatoes into very thin rounds, about 1–2 mm thick. A mandoline slicer works best for achieving consistent thickness, which ensures even frying and uniform crunchiness.

→ Why do I need to rinse and dry the potato slices?

Rinsing removes excess starch, which prevents chips from sticking together and helps them crisp up better. Drying thoroughly is crucial—any moisture left on the surface will cause splattering and prevent proper crisping.

→ What oil works best for frying?

Sunflower, canola, or peanut oil are ideal choices due to their high smoke points and neutral flavors. These oils can maintain the 170°C frying temperature without breaking down or imparting unwanted tastes.

→ How do I know when the chips are done?

Chips are ready when they turn golden brown and become rigid. They should make a hollow sound when tapped. Total frying time is typically 2–3 minutes, but watch closely as thin slices can brown quickly.

→ Can I bake these instead of frying?

While baking produces a lighter result, it won't achieve the same ultra-crispy texture as deep-frying. For baked versions, brush slices lightly with oil and bake at 200°C for 15–20 minutes, flipping halfway through.

→ How long will homemade chips stay fresh?

Store completely cooled chips in an airtight container at room temperature. They'll maintain their crunch for 2–3 days. Avoid refrigerating, as moisture can make them soggy. If they lose crispness, a quick 5-minute oven refresh at 150°C helps.
