What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with a couple of fresh additions to make it pop.

• Sweet potatoes: 3 medium-sized (about 1.5 pounds or 700 grams), peeled and cut into 1/4-inch thick fries (look for firm, evenly shaped potatoes for uniform cooking).
• Olive oil: 2 tablespoons (extra virgin preferred for flavor).
• Sea salt: 1 teaspoon (coarse flakes work best for that crunch).
• Fresh rosemary: 1 tablespoon, finely chopped (adds a fragrant, piney note).
• Garlic powder: 1/2 teaspoon (for subtle depth).
• Smoked paprika: 1/2 teaspoon (gives a mild smoky warmth).
• Black pepper: 1/4 teaspoon, freshly ground.
• Optional: A pinch of cayenne pepper for a little kick (adjust to taste).

If you want to swap olive oil, avocado oil works just as well for a neutral flavor and high smoke point. For a gluten-free twist, all ingredients here are naturally gluten-free, so you’re good to go. If fresh rosemary isn’t available, dried rosemary can do in a pinch—just crush it finely so it’s not too woody. I usually recommend using fresh rosemary for that bright, fresh hit.

Equipment Needed

• Baking sheet: A large rimmed baking sheet ensures the fries have room to crisp up without steaming.
• Parchment paper or silicone baking mat: Prevents sticking and helps with even browning.
• Sharp knife and cutting board: For cutting sweet potatoes into uniform fries.
• Large bowl: For tossing fries with oil and seasoning.
• Measuring spoons: To get those perfectly balanced spices and salt ratios.

If you don’t have a silicone baking mat, regular parchment paper works fine and is budget-friendly. I’ve tried cooking on bare baking sheets before, but fries tend to stick and get uneven color, so trust me on this one. Also, a good sharp knife makes cutting the fries less of a chore and safer too. I use a santoku knife that’s been my kitchen buddy for years—easy to handle and keeps a fine edge.

Preparation Method

1. Preheat your oven: Set to 425°F (220°C). This high heat is key for that crispy finish.
2. Prepare the sweet potatoes: Peel and cut 3 medium sweet potatoes into 1/4-inch thick fries. Try to keep the sizes consistent so they cook evenly.
3. Soak the fries: Place the cut fries in a large bowl of cold water and soak for at least 30 minutes (or up to 2 hours if you have time). This step helps remove excess starch—trust me, it makes a big difference.
4. Dry thoroughly: Drain the fries and pat them completely dry with a clean kitchen towel or paper towels. Moisture is the enemy of crispiness, so no rushing this part.
5. Toss with oil and seasoning: In a large bowl, combine 2 tablespoons of olive oil, 1 teaspoon sea salt, 1 tablespoon finely chopped fresh rosemary, 1/2 teaspoon garlic powder, 1/2 teaspoon smoked paprika, and 1/4 teaspoon fresh black pepper. Add fries and toss until evenly coated.
6. Arrange on baking sheet: Spread fries out in a single layer on a parchment-lined baking sheet. Make sure they aren’t crowded—overlapping fries steam instead of crisp.
7. Bake: Place fries in the oven and bake for 15 minutes. Then, flip fries using a spatula for even cooking and bake another 10-15 minutes until edges are golden and crisp.
8. Final seasoning: When fries come out of the oven, immediately sprinkle a little extra rosemary salt if desired for that fresh burst of flavor.
9. Serve: Let fries cool for a few minutes (they’ll crisp a bit more) and serve warm.

Pro Tip: If you notice fries are soft rather than crispy, your oven temperature might be a bit low or the fries were too crowded. Next time, try spacing them out more and avoid skipping the soak-and-dry step! Also, flipping halfway through is essential for even browning.

Cooking Tips & Techniques

Getting crispy sweet potato fries can be tricky, but a few tips go a long way. First, soaking your fries in cold water removes surface starch, which keeps them from sticking together and helps that golden crunch develop. Seriously, don’t skip this step!

Next, drying the fries thoroughly is just as important. I learned this the hard way after a soggy first batch. Water on fries equals steam, and steam equals limp fries. Pat them down until they feel almost dry to the touch.

Oven temperature is key—425°F (220°C) gives you that perfect balance between cooking the inside tender and crisping the outside. Lower temps just won’t cut it. Also, using a rimmed baking sheet lined with parchment or a silicone mat keeps them from sticking and promotes even heat circulation.

Flipping halfway through baking is non-negotiable. It’s tempting to just leave them, but turning fries ensures every side gets exposure to that hot air, giving you a uniform crunch. When seasoning, mixing your spices and oil before tossing fries guarantees every piece is coated, avoiding bland bites.

Finally, don’t be afraid to experiment with a pinch of cayenne or a dash of cumin in your rosemary salt mix for a personalized flavor kick. Cooking is as much about fun as it is about food!

Variations & Adaptations

This crispy sweet potato fries recipe is pretty flexible, which makes it great for different tastes and dietary needs.

• Spicy Kick: Add 1/4 teaspoon cayenne pepper or chipotle powder to the rosemary salt for a smoky heat. I tried this once for a game day party and it was a total hit!
• Garlic-Parmesan: Toss fries with garlic powder and freshly grated Parmesan after baking for a savory twist that pairs beautifully with the rosemary.
• Oven to Air Fryer: If you have an air fryer, cook the fries at 400°F (200°C) for about 15 minutes, shaking halfway through. It cuts down cooking time and boosts crispness.
• Allergen-Friendly: This recipe is naturally gluten-free and dairy-free, making it suitable for many diets. For those avoiding nightshades, you can omit smoked paprika and replace with a pinch of turmeric for color.
• Seasonal Swap: In fall, try adding a sprinkle of cinnamon and nutmeg to the rosemary salt for a cozy, warming flavor profile.

Serving & Storage Suggestions

These crispy sweet potato fries are best served hot and fresh right out of the oven, but if you need to hold them for a bit, keep them on a wire rack in a warm oven (around 200°F or 90°C) to avoid sogginess. Pair them with a tangy garlic aioli, chipotle mayo, or even a simple ketchup for dipping.

They make a fantastic side for burgers, grilled chicken, or even a hearty salad. For drinks, a crisp lemonade or a cold beer pairs beautifully with the herbal and smoky notes.

To store leftovers, place fries in an airtight container in the refrigerator for up to 3 days. Reheat in a hot oven or air fryer to bring back crispness—microwaving will just make them limp.

Flavors develop nicely the next day, especially the rosemary salt’s aroma, so leftovers can be a tasty snack or quick side. Just remember to re-crisp before serving for the best experience.

FAQs About Crispy Sweet Potato Fries with Rosemary Salt

How do I make sure my sweet potato fries are crispy and not soggy?

Can I use dried rosemary instead of fresh?

Yes, you can! Just make sure to crush dried rosemary finely to avoid woody bits. Fresh rosemary offers a brighter flavor, but dried is a good substitute in a pinch.

Is it possible to make these fries in an air fryer?

Absolutely! Cook at 400°F (200°C) for about 15 minutes, shaking or tossing halfway through for even cooking. It’s a faster way to get crispy fries without the oven.

Can I prepare the fries ahead of time?

You can cut and soak the fries a few hours in advance, but it’s best to dry, season, and bake them just before serving for optimal crispness.

What dipping sauces go well with these sweet potato fries?

Garlic aioli, chipotle mayo, honey mustard, or classic ketchup are all fantastic choices. You can even mix Greek yogurt with herbs for a fresh, creamy dip.
