Shake Shack’s Crinkle Cut Fries

Make Shake Shack’s iconic crinkle cut fries at home! This copycat recipe delivers crispy, seasoned fries just like the real thing — baked or air fried in under 30 minutes.

If you’ve ever bitten into a basket of Shake Shack’s crinkle cut fries, you know they hit differently.

They’re crispy on the ridges, fluffy on the inside, perfectly salted, and somehow way more satisfying than a regular fry. The good news?

You can make a seriously close copycat version right at home — and this recipe is written with the air fryer in mind, because that’s where crinkle cut fries truly shine.

This recipe is designed for anyone who want restaurant-quality results without a deep fryer. Whether you’re serving these alongside a smash burger, dipping them in a homemade cheese sauce, or just eating them straight off the tray, these fries are going to become a regular in your rotation.

Looking for something different than the same old potato side? Some of my favorite Air Fryer Vegetable recipes include AIR FRYER SWEET POTATO FRIES, AIR FRYER AVOCADO FRIES, JICAMA FRIES (AIR FRYER), and AIR FRYER GREEN BEAN FRIES.

Why This Recipe Works

Shake Shack’s crinkle cut fries have a very specific texture, crispy exterior, tender interior, and a slightly thicker cut that holds up to dipping without going soggy.

The ridges are key: they create more surface area, which means more crunch in every single bite. Getting that at home comes down to three things, the right potato, the right cut, and a good soak in cold water before cooking.

This recipe works in both the air fryer and the oven, with notes for each method below.

What You’ll Need — The Crinkle Cutter

To get authentic crinkle cut fries, you’ll need a crinkle cutter knife. They’re inexpensive (usually under $10 on Amazon) and make a huge difference. If you don’t have one, you can still make this recipe with regular cut fries and the seasoning will be just as good — but the ridges are what give these fries that signature Shake Shack look and crunch.

Ingredients Needed

• Russet potatoes: Starchy potatoes create crispy golden crinkle fries
• Olive oil: Helps crisp fries while adding light flavor
• Kosher salt: Enhances natural potato flavor and seasoning balance
• Black pepper: Adds mild heat and subtle earthy spice
• Garlic powder: Brings savory aroma and rich garlic flavor
• Smoked paprika: Adds smoky depth and warm red color

• Kosher salt: Base seasoning for balanced salty flavor
• Celery salt: Adds earthy, slightly tangy savory notes
• Garlic powder: Enhances savory depth and aromatic flavor
• Onion powder: Adds subtle sweetness and savory background flavor
• Cayenne: Brings spicy heat and bold flavor kick
• ShackSauce: Creamy dipping sauce with tangy savory flavor
• Cheese sauce: Rich, creamy dip for extra indulgence
• Ketchup: Classic sweet and tangy fry dipping sauce

Instructions

Step 1: Prep the potatoes. Scrub the russet potatoes clean. You can peel them or leave the skin on. Shake Shack leaves some skin on for a more rustic look. Using your crinkle cutter, slice the potatoes into fries about ¼ to ⅓ inch thick. Try to keep them uniform so they cook evenly.

Step 2: Soak in cold water. Place the cut fries in a large bowl of cold water and let them soak for at least 20-30 minutes, or up to 2 hours. This draws out excess starch and is the single most important step for getting a crispy fry. Don’t skip it.

Step 3: Dry thoroughly. Drain the fries and spread them out on a clean kitchen towel or paper towels. Pat them completely dry. Any remaining moisture will steam instead of crisp in the air fryer or oven.

Step 4: Season. Toss the dried fries with oil, salt, pepper, garlic powder, and smoked paprika until every fry is evenly coated.

Step 5 (Air Fryer Method): Cook at 380°F for 18-22 minutes, shaking the basket every 6-7 minutes. Work in batches if needed, overcrowding is the enemy of crispy fries. The fries are done when the ridges are deep golden brown and the edges are visibly crispy.

Step 5 (Oven Method): Preheat the oven to 425°F. Spread the fries in a single layer on a wire rack set over a baking sheet. This allows air to circulate underneath for even crisping. Bake for 25–30 minutes, flipping once at the halfway point.

Step 6: Finish with seasoning salt. While the fries are hot out of the fryer or oven, immediately toss or sprinkle with the seasoning salt blend.

Pro Tips for Extra Crispy Crinkle Cut Fries

• Soak longer for crispier fries. A 2-hour soak produces noticeably crispier results than a 20-minute soak. If you’re planning ahead, soak the fries in the fridge overnight.
• Double fry for the crispiest results. If using the oven, do a first bake at 375°F for 15 minutes, let the fries cool for 5 minutes, then finish at 425°F for another 10–12 minutes. This mimics the double-fry method used in restaurant kitchens.
• Use avocado oil for a higher smoke point. If your air fryer runs hot, avocado oil holds up better than olive oil at higher temperatures and produces a cleaner flavor.
• Russet potatoes only. Their high starch content is what gives you that fluffy interior. Waxy potatoes like red or fingerling will not give you the same result.
• Season while hot. This cannot be overstated. Salt sticks to a hot, slightly oily fry. If you wait until they cool, the seasoning just falls off.

The ShackSauce Copycat

No Shake Shack fry experience is complete without a dipping sauce. Here’s a simple ShackSauce copycat that pairs perfectly: combine ½ cup mayonnaise, 1 tablespoon ketchup, 1 tablespoon yellow mustard, 1 teaspoon pickle brine, a pinch of cayenne, and salt to taste. Stir well and refrigerate for at least 15 minutes before serving. It’s tangy, creamy, and absolutely addictive.

Variations

• Loaded cheese fries: Top the hot fries with a homemade cheese sauce (melt butter, whisk in flour, add whole milk and shredded cheddar), crumbled bacon, and sliced scallions. This is Shake Shack’s loaded fries done at home.
• Truffle fries: Toss the finished fries in a small drizzle of truffle oil, a sprinkle of flaky sea salt, and freshly grated Parmesan. Serve immediately.
• Spicy fries: Add ½ teaspoon of chipotle powder and a pinch of cayenne to the seasoning mix for a smoky, spicy kick.
• Frozen crinkle cut fries shortcut: In a hurry? Grab a bag of frozen crinkle cut fries (Ore-Ida or Alexia are great brands) and use the seasoning salt recipe above to upgrade them instantly. Air fry according to the package directions, then season hot.

Storage and Reheating

Crinkle cut fries are always best fresh, but if you have leftovers store them in an airtight container in the refrigerator for up to 2 days. Reheat in the air fryer at 375°F for 4–5 minutes to bring back the crispiness. Avoid the microwave — it makes fries soft and rubbery.

Frequently Asked Questions

What makes Shake Shack’s crinkle cut fries different from regular fries? The ridged shape creates significantly more surface area, which means more crispy edges per fry. Shake Shack also seasons their fries well and serves them hot, which makes a big difference in the overall experience.

Can I use frozen crinkle cut fries for this recipe? Absolutely. If you want the homemade version, follow the recipe above. If you’re short on time, grab a bag of frozen crinkle cut fries and apply the seasoning salt from this recipe right after air frying. You’ll get very close to the real thing with about 5 minutes of effort.

Do I really need to soak the potatoes? Yes. Skipping the soak results in fries that are soft in the middle and barely crispy on the outside. The soak removes surface starch that would otherwise steam the fry from within instead of letting it crisp up.

What is the best potato for homemade fries? Russet potatoes are the gold standard for fries. Their high starch and low moisture content gives you that crispy outside and fluffy inside combination. Yukon Golds work as a secondary option and produce a slightly creamier interior.

Can I make these ahead of time? You can cut and soak the potatoes up to 24 hours in advance (store in cold water in the fridge). Cook them fresh right before serving for best results.

Why are my homemade fries not crispy? The most common reasons are not soaking the potatoes long enough, not drying them thoroughly before cooking, overcrowding the pan or basket, or using too little oil. Address any of these and your results will improve dramatically.
