An overhead shot of golden-brown turnip fries artfully arranged in a vintage wire basket lined with parchment paper. The fries show perfect caramelization with visible flecks of herbs and seasoning against their crispy exterior. A small ramekin of creamy garlic aioli sits alongside, its surface rippled from a fresh dip. Soft natural light casts gentle shadows across a rustic wooden table, while scattered fresh rosemary sprigs and a sprinkle of flaky sea salt add dimension. The contrast between the golden exterior and the slightly paler interior of a broken fry reveals the perfect texture - crisp edges giving way to a tender center.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 220°C (425°F) and line two baking sheets with parchment paper. The high temperature is crucial for achieving crispy exteriors while maintaining tender insides.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Peel the turnips or rutabagas completely, as the skin can be tough and bitter. Slice them into fry-shaped sticks about 1cm thick – aim for uniform sizes to ensure even cooking. Thinner cuts will become crispier but cook faster, while thicker ones will have more of a tender interior.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Place the cut vegetable sticks in a large bowl of cold water and let them soak for 10 minutes. This removes excess starch and helps achieve a crispier result. After soaking, drain thoroughly and pat completely dry with kitchen towels – any remaining moisture will create steam and prevent proper crisping.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>In a large bowl, combine the olive oil, garlic powder, paprika, rosemary, onion powder, salt, and pepper. Add the dried vegetable sticks and toss until they're evenly coated. The oil not only helps with crisping but also helps the seasonings adhere to the surface.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Arrange the seasoned sticks in a single layer on the prepared baking sheets, ensuring they don't touch each other. Overcrowding the pan will cause them to steam rather than roast, resulting in soggy rather than crispy fries.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Bake for 15 minutes, then carefully flip each piece and rotate the baking sheets in the oven to ensure even browning. Continue baking for another 10-15 minutes until the fries are golden brown and crisp around the edges. Watch carefully during the last few minutes as they can go from perfectly crisp to burnt quite quickly.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Once done, remove from the oven and let them rest on the baking sheets for 2-3 minutes – they'll become slightly crispier as they cool. Season with additional salt if desired and serve immediately for the best texture and flavor. Unlike potato fries, these root vegetable versions are best enjoyed fresh from the oven as they can soften when stored.</li></ol>

Chef’s Notes

A few helpful details for making this recipe.

Why are my root vegetable fries soggy instead of crispy?

Soggy fries usually result from excess moisture, overcrowding the baking tray, or too low oven temperature. Ensure you thoroughly pat dry your turnips after soaking, arrange them in a single layer without touching, and bake at a high temperature (220°C/425°F) for proper crisping.

Can turnip fries be made in an air fryer instead of the oven?

Yes! Air fryers work brilliantly for turnip fries. Prepare them as directed, then air fry at 200°C for about 15 minutes, shaking the basket halfway through. The circulating hot air creates exceptionally crispy results with less oil and shorter cooking time than conventional ovens.

How do turnips compare to potatoes in terms of carbohydrate content?

Turnips contain significantly fewer carbohydrates than potatoes, making them ideal for low-carb diets. Per 100g, turnips have approximately 4-6g of carbs compared to potatoes' 17-20g. This represents about a 70% reduction, while still providing that satisfying root vegetable texture and flavour.
