Kohlrabi Fries (Air Fryer or Oven)

If you’ve never tried kohlrabi fries, you’re in for a treat. This simple recipe shows you how to make them in both the air fryer and the oven, so you can enjoy them no matter your cooking style. They’re tender, lightly spiced, and a fun twist on the classic French fry – the perfect way to turn this underrated vegetable into a crowd-pleasing side dish.

Kohlrabi might not be the first veggie you think of when it comes to fries, but trust me – once you try these kohlrabi fries, you’ll want to make them again and again. Whether in the air fryer or baked in the oven, they’re a fun and flavorful side dish that’s a little different from your regular fries. I love making vegetable fries anyway. I’ve made zucchini friesbroccoli fries, celeriac fries, sweet potato fries (check how to make those crispy with sweet potato tempura fries), and of course also regular potato fries

Ingredients

  • Kohlrabi – 1 large or 2 small (enough for 2 people as a side dish).
  • Olive oil – About 2 tablespoons, to coat the fries.
  • Spices – I used chili powder, smoked paprika, garlic powder, onion powder, and a pinch of sea salt.
    • Try variations like ras el hanout, curry powder, or Italian seasoning for a new twist, but really any kind of spices will work well.

If you’re not familiar with kohlrabi yet, make sure to read the article “What is kohlrabi“. You should be able to find kohlrabi in the better assorted grocery stores, farmer’s markets, or your green grocer. One of my favorite recipes with kohlrabi is this recipe for roasted kohlrabi with garlic butter.

How to Make Kohlrabi Fries

Slicing and cleaning the kohlrabi into sticks

Step 1: Prepare the kohlrabi

Peel the tough woody skin, then cut into evenly sized sticks. Aim for medium thickness – too thin and they burn, too thick and they won’t cook through evenly. Peeling is easily done using a vegetable peeler or a sharp knife

Season the kohlrabi fries

Step 2: Season the fries

In a large bowl, mix olive oil with your chosen spices and salt. Add the kohlrabi sticks and toss until well coated.

Step 3: Cook the fries

Oven method:
Preheat the oven to 400°F (200°C). Spread fries evenly on a baking sheet lined with parchment paper. Bake for 20–25 minutes, flipping halfway, until golden and tender.

Air fryer method:
Place the fries in a single layer in the air fryer basket (cook in batches if needed). Cook at 400°F (200°C) for 12–15 minutes, shaking once halfway through. Check after 10 minutes so they don’t over-brown.

Serve with your favorite dip.

Are Kohlrabi Fries Crispy?

Not really. Kohlrabi fries don’t get crispy like potato fries. Instead, they’re tender and flavorful – a bit like sweet potato fries, which also tend to stay soft. But that’s part of their charm: they’re a lighter, veggie-packed alternative with their own unique texture. if you’re looking for funky different fries, check out the polenta fries or funchi fries too.

Serving Suggestions

  • Dip ideas – Try them with garlic aioli, spicy mayo, or ranch dressing. Or whatever your favorite dip is. 
  • Meal pairings – Serve alongside burgers, grilled chicken, or roasted salmon.
  • Topping tip – Sprinkle with Parmesan cheese or fresh herbs right after cooking for extra flavor.

FAQ Kohlrabi Fries

It has a mild, slightly sweet flavor, somewhere between broccoli stem and cabbage.

They’re best enjoyed fresh, but you can cut the kohlrabi in advance and keep it in an airtight container in the fridge for 1–2 days.

Yes – you can skip the oil, but they won’t brown as nicely. A light spray of cooking oil helps with flavor and texture.

Expert Tip

For the best results, don’t overcrowd the pan or air fryer basket. Kohlrabi releases a bit of moisture as it cooks, and if the pieces are piled on top of each other, they’ll steam instead of roast. By keeping the fries in a single layer with space between them, you’ll get more even cooking and that golden, slightly caramelized edge that makes them so delicious.
