How to Make Crispy Rosemary Baked Fries

These are perfectly crispy rosemary baked fries. A quick 10-minute soak delivers the best oven-baked fries I’ve ever tasted.

The elusive perfectly crisp baked fry — I’ve chased it for years. I tried slicing potatoes into rounds and spraying both sides, cutting them into matchsticks, and even roasting potato cubes. Each technique had its drawbacks, and none delivered that classic fry contrast: a golden, crisp exterior with a soft, tender center.

Then I discovered a simple method that changed everything: a short ten-minute soak in hot water, parchment-lined baking sheet, toss in a little oil, and bake on a low oven rack. It’s easy, fast, and consistent. The ten-minute soak removes excess surface starch and helps the fries crisp up in the oven without the need for hours of soaking or deep frying.

I tried this approach multiple times in a short span because I had potatoes that needed using, and the results were so good I couldn’t stop. Even when the smoke alarm went off a few times and the dog hid in the laundry room, the end result was worth it: the crispiest baked fries I’ve found.

To highlight fresh herbs, I added chopped rosemary. Rosemary gives baked potatoes a fragrant, savory lift — I use it on a range of fries from parsnip to sweet potato. You can keep these plain and simple, or customize with parmesan, scallions, masala spices, or cheddar for different flavor profiles. Fresh rosemary works beautifully here and makes these fries feel special without extra effort.

The only disappointment was running out of ketchup halfway through — salsa was an okay substitute, but not quite the same. Serve these fries hot and crisp and plan condiments accordingly.

More fry ideas

If you enjoy these rosemary baked fries, try other baked vegetable fry variations like jicama fries, eggplant fries seasoned with Italian spices, green bean fries, lemon-dijon asparagus fries, or zucchini fries. The same basic technique — a short soak, a bit of oil, and high-heat roasting — works well for many vegetables.

Perfectly Crispy Rosemary Baked Fries

Ingredients

• 3 small russet potatoes, scrubbed and cut into fry-like slices
• 3 tablespoons extra virgin olive oil, divided
• Salt and freshly ground black pepper, to taste
• 1/2 tablespoon fresh rosemary, chopped, plus more for garnish
• 1/4 teaspoon cayenne pepper (optional, for a kick)
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon ground cumin

Instructions

1. Preheat the oven to 475°F (245°C) and position a rack in the second slot from the bottom.
2. Line a baking sheet with parchment paper. Drizzle the paper with 2 tablespoons of olive oil and sprinkle with a pinch of salt and pepper.
3. Place the cut potato slices in a medium bowl and cover with hot water. Let them soak for 10 minutes to remove excess starch.
4. Drain the potatoes and pat them thoroughly dry with a clean towel or paper towels.
5. Toss the dried potato slices with the remaining 1 tablespoon of olive oil, the cayenne (if using), smoked paprika, cumin, chopped rosemary, and additional salt and pepper to taste.
6. Spread the fries into an even single layer on the prepared baking sheet. Cover the pan loosely with foil.
7. Bake for 5 minutes covered, then remove the foil and bake for another 10 minutes.
8. Rotate the pan, bake an additional 5 minutes, then flip each fry individually and bake for a final 5 minutes, or until the fries are golden and crisp to your liking.
9. Remove from the oven, sprinkle with more salt and pepper if desired, and garnish with additional rosemary.
10. Serve immediately for best texture and flavor.
