FAQs
Do air-fried radishes really taste like potatoes?
Yes! When air fried, radishes lose their peppery bite and become mellow, tender, and surprisingly similar in texture and flavour to roasted baby potatoes.
Can I use other root vegetables?
Turnips or kohlrabi are great low-carb alternatives, but avoid carrots or parsnips as they are higher in carbs.
How do I get the crispiest result?
Pat the radishes dry before tossing with oil and avoid overcrowding the air fryer basket so the hot air can circulate.
Can I make these ahead?
They are best fresh, but you can reheat leftovers in the air fryer for 3–4 minutes at 180°C to restore crispiness.
Are these suitable for meal prep?
Yes, store cooked radishes in the fridge and reheat in the air fryer for a quick, crispy side.
