These crispy oven-roasted turnip fries are the keto answer to a French-fry craving, with a golden parmesan-garlic crust and a fraction of the carbs of regular potatoes. Serve them alongside burgers, grilled chicken, or steak for a side that nobody will guess is low-carb.
Ingredients
- 1.5 lbs turnips (about 3 medium), peeled
- 3 tablespoons extra-virgin olive oil
- 1/4 cup grated parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 1/2 teaspoon onion powder
- 3/4 teaspoon fine sea salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon chopped fresh parsley (for garnish)
Instructions
- 1
Preheat the oven to 425°F (220°C) and line two large baking sheets with parchment paper.
- 2
Cut the peeled turnips into 1/4-inch thick fry-shaped sticks, keeping them as uniform as possible so they cook evenly.
- 3
In a large bowl, toss the turnip sticks with olive oil until fully coated. Add the parmesan, garlic powder, smoked paprika, onion powder, salt, and pepper, and toss again until every fry is evenly seasoned.
- 4
Spread the fries in a single layer across both baking sheets, leaving space between each so they roast instead of steam. Crowding the pan is the number one cause of soggy fries.
- 5
Bake for 25 minutes, flipping the fries and rotating the pans halfway through, until the edges are deeply golden and crisp.
- 6
Garnish with fresh parsley and serve immediately while hot and crispy.
Tips & notes
- Turnips are naturally much lower in carbs than potatoes, but they hold more water, so a thorough toss in oil and plenty of space on the pan are key to crispiness. Patting the cut fries dry with a paper towel helps even more.
- For extra-crisp fries, broil for the final 1-2 minutes, watching closely so the parmesan doesn't burn.
- Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in a 400°F oven or air fryer for 5-6 minutes to restore the crunch; the microwave will leave them soft.
