Jicama fries cook in the air fryer in about 20 minutes at 400 °F (204 °C), shaken once at the halfway mark, after a quick parboil to soften them. Jicama — the crisp, faintly sweet Mexican root sometimes called yam bean — has flesh so firm it won't tenderize under dry air alone, so the trick is to peel deep, cut even batons, and boil or steam them 8–10 minutes before tossing with oil and air-frying; that pre-cook is what lets them turn golden and tender-crisp instead of raw and woody. The payoff is a very low-carb, high-fibre fry that stays satisfyingly crunchy — a favourite on keto and low-carb plates. Unlike Yuca Fries (dense, starchy cassava that fluffs soft inside), Polenta (crisp-shelled but creamy cornmeal), or Rutabaga (a sweeter root that roasts fully tender), jicama keeps its signature crunch and never goes fully soft. 4 ways to make it: chili-lime, garlic-Parmesan, Cajun, and ranch.

How to tell it’s done

Done when the batons are golden at the edges and tender-crisp — jicama stays noticeably crunchier than a potato fry and never goes fully soft, so don't wait for that fluffy-potato give. Shake the basket at the halfway mark so they brown on all sides. Go by colour and a firm bite; there's no internal temperature to hit.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Yes — pat the parboiled batons dry, then toss with a little oil so the edges brown and crisp instead of drying out in the dry heat.

2. 2

   Season

   Season with Chili-lime: a Tajín or chili-lime blend with a squeeze of lime after cooking — the classic Mexican street treatment for jicama., Garlic-Parmesan: olive oil, garlic, and grated Parmesan tossed on in the last few minutes., Cajun: a Cajun or blackening blend for a spiced low-carb fry., Ranch: dry ranch seasoning for a tangy, herby keto-friendly fry..

3. 3

   Load

   Arrange one medium jicama (~3 cups of batons), in a single layer; serves 2–3 as a low-carb side for best convection airflow.

4. 4

   Cook

   Set the air fryer to 400 °F (204 °C) and cook for 20 minutes total, shaking once at 10 minutes.

5. 5

   Check & rest

   Check the visual doneness cue and serve immediately for best texture.

6. 6

   Store

   Refrigerate cooked jicama fries airtight up to 3–4 days and re-crisp at 400 °F (204 °C) for 3–4 minutes — they soften a little once cool. Raw peeled jicama keeps cut and submerged in water in the fridge for up to a week.

Watch out for

• !Parboil or steam the batons 8–10 minutes first — jicama's crisp flesh barely softens under dry air alone, so without a pre-cook it comes out raw and woody no matter how long you fry it.
• !Peel off the thick fibrous brown skin and the stringy layer just beneath it, down to the white flesh; that papery skin is not edible.
• !Pat the parboiled batons thoroughly dry before oiling — surface water steams the edges and stops them browning.
• !Cut even ¼–½-inch batons and keep them in a single layer; crowding steams them and uneven pieces cook at different rates.
• !Don't expect a soft potato-fry interior — jicama is meant to finish tender-crisp; pushing it longer just dries the outside.

FAQ about jicama fries in an air fryer

What temperature should I cook jicama fries at in an air fryer?

Cook jicama fries at 400 °F (204 °C). The convection air at this temperature browns the exterior quickly without drying the centre.

How long do jicama fries take in an air fryer?

Jicama fries take 20 minutes total at 400 °F (204 °C). Shake the basket once at 10 minutes so both sides cook evenly.

Do you need to shake jicama fries in an air fryer?

Yes — shake the basket once at 10 minutes. Loose pieces (jicama fries) settle into the basket and the bottom layer stays pale unless you redistribute them halfway through.

Do you need to preheat the air fryer for jicama fries?

Preheating is optional for jicama fries — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.
