Side Dishes
Zingerman's sweet potato fries recipe delivers that signature smoky paprika crunch over creamy, velvety sweet potato perfection—just like the famous Ann Arbor deli's version. The secret lies in thinly sliced sweet potatoes baked until crispy outside while staying tender inside, then finished with a bold spice blend that sticks like magic. I've perfected this technique after years of testing, and it's become my go-to side dish for game days and family dinners alike.
The magic happens in the preparation: cutting the sweet potatoes into even sticks (about 1/4-inch thick) ensures they cook uniformly, while a hot oven (425°F) creates that signature crispiness in just 20-25 minutes.
The seasoning—smoked paprika, garlic powder, and a touch of cayenne—adds depth without overpowering the natural sweetness of the potatoes. This isn't just a side dish; it's a flavor experience that transforms ordinary meals into something special.
What makes these fries truly stand out is the perfect balance of textures: shatteringly crisp edges that give way to a creamy, almost custard-like interior. The spice blend clings to every surface, creating a flavor profile that's both smoky and slightly sweet.
Serve them with your favorite dipping sauce—Zingerman's original calls for their creamy mustard—but I've found that a tangy chipotle aioli or even honey mustard takes them to the next level.
For those watching their oil intake, air-frying works beautifully with just a slight adjustment in cooking time and temperature. The result is nearly identical in flavor and texture, proving that you can achieve restaurant-quality sweet potato fries without deep-frying.
Whether you're feeding a crowd or treating yourself to a snack, these fries are a game-changer that will have everyone asking for seconds.

The sweet potatoes are the star—pick firm, evenly shaped ones from the produce section. Trader Joe's and Whole Foods usually have the best selection, but regular grocery stores work too. Look for vibrant orange color and smooth skin. Peeled and cut into even 1/4-inch sticks, they'll cook uniformly. For extra crispiness, I toss them with baking powder before baking. The smoked paprika is non-negotiable—it's what gives those fries their signature Zingerman's flavor. Grab the Penzeys brand if you can find it, or any high-quality smoked paprika from the spice aisle.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Short on cayenne? Red pepper flakes at half the amount works too. The mustard powder adds a subtle tang that balances the sweetness—skip it if you're using a tangy dipping sauce. For the dipping sauce, Zingerman's creamy mustard is ideal, but any good-quality whole-grain mustard thinned with a splash of milk works. If you're air-frying, reduce the olive oil to just 1 tablespoon—these fries still turn out crispy and delicious. The key is even cooking, so don't overcrowd the pan or baking sheet.
These fries reheat beautifully—just pop them in a 350°F oven for 5-7 minutes until crispy again. Store leftovers in an airtight container for up to 3 days, but honestly, they disappear fast. For meal prep, I portion them into single servings and freeze them raw (before baking). They keep for 2 months in the freezer—just bake straight from frozen, adding 5-7 minutes to the cooking time. The secret to restaurant-quality texture? Don't skip the baking powder—it's what gives them that extra crunch.

Step-by-step instructions for Zingerman's sweet potato fries
Here's how to create crispy, smoky fries that pair perfectly with that creamy mustard sauce.
Prep and Season the Sweet Potatoes
Start by peeling the 2 lbs of sweet potatoes and cutting them into ¼-inch thick sticks using a mandoline or sharp knife. I find the mandoline gives the most consistent thickness, which is key for even cooking. Soak the cut fries in cold water for 15 minutes to remove excess starch—this helps them crisp up beautifully instead of turning soggy.
After soaking, drain well and pat completely dry with paper towels. In a large bowl, toss the sweet potatoes with the 2 tbsp smoked paprika, 1 tbsp garlic powder, 0.5 tsp cayenne pepper, 1.5 tsp salt, and 0.5 tsp black pepper. I like to use my hands for this—it helps the spices adhere evenly to every surface. Let them sit for 10 minutes while you preheat your oven.
Create the Crispy Coating
In a separate bowl, whisk together the 2 tbsp olive oil, 1 tsp baking powder, 0.5 tsp mustard powder, and 0.5 tsp onion powder. The baking powder might seem unusual, but it works wonders for extra crispiness. Pour this mixture over the seasoned sweet potatoes and toss gently but thoroughly to coat every stick evenly.
Here's the thing—don't rush this step. You want the oil and spices to cling to the sweet potatoes so they develop that perfect crunch. Spread them out on a baking sheet in a single layer, leaving about ½ inch between each piece. This prevents steaming and ensures maximum crispiness.
Bake to Golden Perfection
Preheat your oven to 425°F. Once hot, place the baking sheet on the middle rack and bake for 20 minutes. After 20 minutes, flip each fry carefully with tongs and bake for another 15-20 minutes until they're golden brown and crispy. You'll know they're ready when they sound hollow when tapped together and have a deep golden color.
I usually bake them in two batches if I don't have two large enough pans, but don't overcrowd the pan—this is what makes the difference between good fries and great fries. The high heat and baking powder combination creates that perfect crunch you're after.
Serve with Creamy Mustard Sauce
Transfer the hot fries to a serving platter and immediately drizzle with any remaining oil from the baking sheet—this adds extra flavor. Serve them right away with the ½ cup creamy mustard sauce on the side. The contrast between the crispy, smoky fries and the cool, creamy sauce is what makes this dish truly special.
For the best experience, I like to serve these fries while they're still piping hot. The sauce should be thick enough to cling to the fries without being too runny. If you're feeling fancy, sprinkle with extra smoked paprika right before serving for that restaurant-quality touch.
Pro Tips For Making Zingerman'S Sweet Potato Fries
- USE A MANDOLINE OR SHARP KNIFE: I learned this the hard way—uneven fries mean some burn while others stay raw. Cut sweet potatoes into ¼-inch sticks (no thicker) and keep them consistent. A mandoline makes this faster, but even a sharp chef’s knife works if you take your time.
- SALT THE FRIES BEFORE FRYING: This isn’t just about flavor—it’s about texture. Toss the cut sweet potatoes in 1 teaspoon of salt (and a pinch of cayenne) before cooking. The salt draws out moisture, helping them crisp up faster and deeper. (Yes, even if you’re impatient like me.)
- DON’T CROWD THE PAN: I used to pile fries in like I was making hash browns—big mistake. Cook them in a single layer, and if you need more space, work in batches. Overcrowding steams them instead of frying, and you’ll end up with soggy, uneven results.
- TOAST THE SPICES FIRST: Skip the pre-mixed spice blends—this recipe’s magic comes from toasting the spices. Heat smoked paprika, garlic powder, and cayenne in a dry pan for 30 seconds until fragrant. The aroma alone makes a difference, and it prevents a bitter aftertaste. (Your future self will thank you.)
Essential equipment for this dish
Must-Have Baking Tools
First up, you'll need a mandoline slicer—I swear by the OXO Good Grips model for its safety and precision. Cutting sweet potatoes into even ¼-inch sticks is key for consistent cooking, and a mandoline makes this task effortless.
If you don't have one, a sharp chef's knife and steady hand will work, but expect some variation in thickness. 🔪
Baking Essentials
Your oven is the star here, so make sure it's calibrated accurately. A digital thermometer like the Thermoworks OvenTherm ensures your oven hits the perfect 425°F.
For baking sheets, I recommend half-sheet pans—they're large enough to fit a single layer of fries without crowding, which is crucial for crispiness. Look for heavy-duty, commercial-grade pans if you can, like those from USA Pan.
Seasoning and Mixing
For tossing and seasoning, a large mixing bowl with high sides prevents spills, especially when using your hands to coat the fries. I love the Le Creuset stoneware bowls for their durability and heat retention.
A whisk is essential for combining the oil and dry spices into a smooth coating—my go-to is the OXO Good Grips whisk for its ergonomic handle.
A fine-mesh strainer helps drain the soaked fries efficiently, and I keep a pack of reusable silicone-lined paper towels on hand for quick drying. 🧂
Serving and Storage
To keep fries crispy during serving, transfer them to a wire cooling rack placed over a baking sheet. This prevents sogginess from steam buildup. For storage, I use glass airtight containers with snap-on lids—Pyrex Simply Store containers work perfectly.
If you're freezing, quart-sized freezer bags with the air squeezed out are ideal for portion control. A kitchen scale (like the OXO Good Grips) ensures you measure the 2 lbs of sweet potatoes accurately, which is crucial for the right balance of flavors. ❄️
Optional Upgrades
For extra crispiness, consider an infrared thermometer like the Kizen to monitor fry temperatures without opening the oven door.
If you're air-frying, a high-quality air fryer (I recommend the Ninja Foodi) with a basket that fits at least 3 lbs of fries at once will give you restaurant-quality results with less oil.
A tongs set with silicone tips is a game-changer for flipping hot fries without losing that perfect crunch. 🍟

Frequently asked questions
Why do the sweet potatoes need to soak before baking? Soaking removes excess starch that would otherwise make your fries gummy instead of crispy. The 15-minute cold water soak helps create that signature Zingerman's texture—shatteringly crisp edges with a creamy interior. Just
Can I make these in an air fryer instead of the oven?
For air frying, reduce the olive oil to 1 tablespoon and cook at 375°F for 12-15 minutes, shaking the basket every 5 minutes. The baking powder still works its magic for extra crunch. Just don't overcrowd the basket—cook in batches if needed for that perfect golden color.
What if my fries turn out soggy instead of crispy?
Three likely culprits: not drying them well enough, overcrowding the pan, or underbaking. First, double-check your drying step—use paper towels and press gently. Second, space them ½ inch apart on the baking sheet. Finally, bake until they're golden brown and sound hollow when tapped together.
How do I make the creamy mustard sauce like Zingerman's?
Mix ½ cup mayonnaise with 2 tablespoons whole-grain mustard, 1 teaspoon Dijon, and a splash of milk to thin. For extra tang, add ½ teaspoon lemon juice. The key is balancing creamy (mayo) with sharp (mustard) flavors. Store leftovers in the fridge for up to 5 days.
Can I use regular potatoes instead of sweet potatoes?
While you can use regular potatoes, the flavor and texture won't be the same. Sweet potatoes have that natural sweetness and creaminess that pairs perfectly with the smoky spices. For a similar texture, try purple potatoes, but they'll lack the signature sweetness. Stick with sweet potatoes for that authentic Zingerman's experience!
