Keto Kohlrabi Fries from the Oven
Potato fries are off the table on keto, a single serving carries roughly 35 g of carbs. Kohlrabi, by contrast, brings only 4 g net per 100 g and surprises in the oven with a remarkably fry-like texture: crisp outside, tender inside. Per serving you get 4 g net carbs, 15 g fat and 5 g protein. With paprika and Parmesan they become an honest alternative, not identical to potato but a strong side in their own right.

Tips for crispy kohlrabi fries
- Cut the sticks evenly, otherwise they bake unevenly.
- Use enough oil, otherwise they turn dry instead of crisp.
- Do not overcrowd, bake in a single layer with no contact.
- Use parchment rather than foil, the fries release more easily.
- Add the Parmesan only after flipping, otherwise it burns.
Why does kohlrabi work as a fries substitute?
Kohlrabi belongs to the brassica family but in flavor and texture sits closer to a young radish or a mild potato. Raw it tastes slightly sweet and crunchy; in the oven its cell sugars caramelize and develop roasted aromas. With only 4 g net carbs per 100 g and 25 kcal it carries roughly 80 percent fewer carbs than potatoes. Olive oil and Parmesan supply the fat that crisps the sticks and delivers the satisfying mouthfeel you expect from fries.

Variations and dips
Cajun style: 1 tsp Cajun seasoning instead of paprika and garlic, spicy and aromatic. With curry: 1 tsp mild curry powder paired with a mango-powder mayo dip (in moderation), an oriental note. With rosemary: stir 1 tsp finely chopped rosemary into the oil, Mediterranean and great with lamb. Dip ideas: plain mayonnaise, garlic-yogurt dip (3 tbsp full-fat yogurt, 1 garlic clove, 1 tbsp olive oil, salt), aioli or a sour cream sauce with chives. With bacon bits: scatter 50 g crisp pan-fried bacon over the fries just before serving, very filling. From celeriac instead of kohlrabi: celeriac works just as well, slightly sweeter and earthier in flavor.

FAQ
Do the fries really turn crispy?
They will not get crispier than potatoes, kohlrabi holds more water and less starch. But with enough heat (220 °C), enough oil and no stacking on the tray, they develop a clear crispy crust. For maximum crunch, finish the baked sticks for 2 minutes in an air fryer at 200 °C.
Can I make them in an air fryer?
Yes, excellent results. Run at 200 °C for 18 minutes and shake halfway through. It saves time and oil, and the result is more even. Add the Parmesan in the last 3 minutes so it does not burn.
How do I reheat them?
Use the oven or air fryer at 200 °C for 5 minutes, they crisp back up. The microwave is fatal for texture, the sticks turn soft and rubbery.
Do kohlrabi fries fit a keto weight-loss plan?
Yes, they are among the lightest swaps here. Potato fries carry around 35 g of carbs per serving, these 4 g at only 190 kcal. With 5 g of protein they need a main course alongside rather than standing alone.
