Roasted Sweet Potato Fries

There was this Tuesday evening when my roommate showed up with a bag of sweet potatoes from the farmer's market, and I'd just been craving something crispy and salty. Within an hour, the kitchen smelled like caramelized orange root vegetables and smoked paprika, and I realized I'd accidentally stumbled onto something better than any takeout fries I'd been missing. The golden edges caught the light while still steaming, and when I dipped one into that creamy, tangy sauce, I knew I'd made something worth repeating.

I brought a big batch to a potluck once, nervous they'd get cold in the car ride, but people went back for thirds even after they'd cooled slightly. Someone asked if they were homemade, and the surprised look when I said yes made the whole thing worthwhile. That's when I realized this wasn't just a snack—it was the kind of dish that makes people linger in the kitchen.

Ingredients

• Sweet potatoes (800 g, about 2 large): Pick ones that feel firm and have unblemished skin; they'll roast more evenly and won't develop soft spots.
• Olive oil (2 tbsp): This is your secret to crispiness—don't skimp or the edges won't caramelize the way you want.
• Smoked paprika (1 tsp): It adds a subtle depth that regular paprika can't touch; it's what makes people ask what that flavor is.
• Garlic powder (1/2 tsp): Fresh garlic burns too easily at high heat, but powder seasons evenly from the first bite.
• Sea salt (1/2 tsp): Finish with a tiny pinch more after roasting if they need it.
• Ground black pepper (1/4 tsp): Freshly ground makes a noticeable difference here.
• Cornstarch or arrowroot powder (1 tbsp, optional): This is the crispy-edge insurance policy—it absorbs moisture and helps them get properly golden.
• Greek yogurt or sour cream (120 g): Greek yogurt keeps it lighter, but sour cream gives a tangier punch if that's your preference.
• Mayonnaise (1 tbsp): Just enough to make the dip silky without tasting heavy.
• Lemon juice (1 tsp): A squeeze that brightens the whole dip and keeps it from tasting flat.
• Dijon mustard (1 tsp): It adds a subtle sharpness that rounds out the cream and mayo.
• Garlic clove (1 small, finely minced): Mince it as small as you can so it disperses throughout without harsh bites.
• Fresh chives or parsley (1 tbsp, chopped): Adds color and a fresh green note that cuts through the richness.

Instructions

Get your oven ready and prep your space:

Preheat to 220°C (425°F) and line your baking sheet with parchment paper so nothing sticks and cleanup is effortless. A hot oven is your friend here—it's what creates those crispy, caramelized edges.

Cut the sweet potatoes into evenly sized fries:

Peel them first, then slice into sticks about 1 cm thick; uniform pieces cook at the same rate so you don't end up with some burnt and others still soft. Aim for consistency and you'll have much better results.

Coat everything evenly with seasonings:

Toss the fries in a large bowl with olive oil, smoked paprika, garlic powder, salt, pepper, and cornstarch if you're using it. Make sure every piece gets coated—this is where the flavor happens.

Arrange them on the baking sheet:

Spread them out in a single layer without overlapping; if they touch, they steam instead of roast and won't get crispy. Give them room to breathe on all sides.

Roast and flip halfway through:

Start with 15 minutes, then pull the sheet out and flip them all over so they brown evenly on both sides. Finish with another 12–15 minutes until the edges are deeply golden and the insides are tender.

Make the dip while they cook:

Mix the Greek yogurt or sour cream with mayo, lemon juice, Dijon mustard, minced garlic, and fresh chives in a small bowl. Taste it, adjust the salt and pepper, and let it chill until you're ready to serve.

Serve hot with dip on the side:

Pull the fries from the oven and serve them immediately while they're still warm and the outsides are at their crispiest. The contrast between hot fries and cool dip is the whole point.

There's something almost meditative about pulling a hot sheet from the oven and watching those golden sticks steam on the counter. It's one of those dishes that tastes fancy enough to impress but easy enough that you'll actually make it on a regular Tuesday night.

Flavor Variations Worth Trying

The base recipe is wonderful on its own, but I've had the most fun playing with seasonings once I figured out what worked. A small pinch of cayenne pepper brings heat if you like things with a bit of kick, while swapping regular paprika for the smoked version softens things for a more subtle taste. I once added a tiny bit of sumac to the dip and couldn't stop eating them—the tartness paired with the creamy tanginess created something almost addictive.

The Secret to Actual Crispiness

The real trick is that cornstarch, if you have it on hand—it absorbs moisture and helps the exterior caramelize instead of just getting soft. I initially skipped it thinking it was unnecessary, and the difference between my first batch and my second batch taught me a lesson I won't forget. The oil matters too; don't use too little or they'll be dry, but don't drown them either. Two tablespoons sounds minimal, but it's the right amount if you're being generous with how you coat them.

Dipping Options and Storage

Beyond the dip I've described, I've paired these with sriracha mixed into mayo, a garlicky tzatziki when I had cucumber on hand, and even a smoky chipotle cream that turned a simple snack into something memorable. Leftover fries can sit in an airtight container in the fridge for a couple of days, though they're best eaten within a few hours when they're still slightly warm. Reheat them in a 180°C oven for about 8 minutes if they've cooled down—the microwave will make them soggy and defeat the whole purpose.

• The dip keeps for up to 2 days refrigerated, so make it ahead if you're prepping for guests.
• Cut sweet potatoes can be stored in cold water in the fridge for a few hours before cooking, though I prefer to use them fresh.
• Don't skip the parchment paper unless you enjoy scrubbing baked-on potato from your baking sheet.

These fries have become my go-to when I need something that feels special but doesn't require much fuss. They've converted more than a few people who swore they'd never enjoy anything as much as regular fries, and that's a small kind of magic that happens in a kitchen.

→ Is cornstarch necessary for crispiness?

Cornstarch or arrowroot powder is optional but can help create a crisper coating on the fries when tossed before roasting.
