Who doesn't like crispy fries?
This air fried turnip fries recipe is a healthy twist on french fries and other starchy veggie fries such as sweet potato or parsnip fries.
We make them on a weekly rotation right now. They are nutritious, gluten free, easy to make and look just like real potato fries!
Of course, they do not taste exactly like the "real deal". After all, they are turnips and not potatoes.
Also, since turnips have a higher water content than potatoes, they aren't as crisp and are softer in the centre.
But thanks to the air fryer, they have delicious caramelised edges. And the simple spice mix I'm coating them in make them taste super yummy in their own right.
What are turnips
Turnips are root vegetables. Like swedes (also called rutabaga), they are a member of the cabbage family.
Fun fact: Until the potato arrived in Europe from the Americas, turnips were the main form of sustenance for the English working classes.
Turnips are tinted purple on the outside and have white flesh.
Their taste is slightly earthy and has a hint of peppery sharpness, which disappears when cooked.
Baby turnips taste sweeter and milder, which is why you should always choose smaller ones rather than larger ones.
Turnips are high in vitamin C and minerals and low in calories.
At 4.6g net carbs per 100 grams (raw), they are also lower in carbohydrates than other low carb potato replacements such as rutabaga or celeriac.
3 turnips (450g once peeled)
1 tablespoon olive oil, avocado oil or coconut oil
½ teaspoon paprika
¼ teaspoon black pepper
⅓ teaspoon salt
¼ tsp garlic powder
pinch of cayenne
¼ tsp onion powder
¼ tsp cumin
How to make turnip fries in the air fryer
Peel and remove the ends of the turnips. Cut into slices then ½ inch fries. Make sure the fries are equal size so they cook evenly.
Tip: If the turnips seem wet, pat them dry with a kitchen towel.
Mix the olive oil, spices and seasoning together in a mixing bowl.
Toss the fries in the mix so they are fully coated.
Preheat the air fryer.
Place the fries in one single layer in the air fryer and cook at 180C / 350F for 8 minutes.
Shake the basket or flip the fries and remove any small ones that may look cooked.
Then, cook for a further 5 - 7 minutes or until evenly browned and cooked to your liking.
How do I make crispy turnip fries?
Spoiler alert! Turnip fries will never be as crispy as potato fries, celeriac fries or sweet potato fries. This is because they contain less starch and have a higher water content.
Nevertheless, here are my top tips to make them as crisp as possible:
- Pat them dry before coating.
- Arrange them in a single layer in the air fryer basket so the air can circulate easily. If you crowd them, they become soggy.
- Eat them straight away, while the caramelised edges are still nice and crisp.
I have a large air fryer and my fries fitted (just about) in a single layer. Ideally, I should have used a little less to give each fry more space.
If you use an air fryer with a round (smaller) basket, I recommend that you air fry in 2 batches.
If you are not bothered about adding carbs, you could add 1-2 tbsp arrowroot to the coating mix. This will increase the crispness of the fries.
Oven cooked turnip fries
Making turnip fries in the oven is equally simple:
- Preheat the oven to 200 C / 400 F.
- Prepare the turnips fries as per recipe.
- Spread them on a parchment paper lined baking sheet in a single layer. Make sure there is space between the fries so the air can circulate evenly.
- Bake for about 20 minutes.
- Then, turn the fries over and continue cooking for a further 8-10 minutes or until they are browned evenly and have crisped up.
- Serve straight away.
Enjoy them alongside a protein of your choice (meat or fish) and with a side salad.
We've had them alongside these airfryer chicken thighs and they were a perfect match.
Using different vegetables
You can make the same recipe using the following vegetables:
- Rutabaga (swede)
- Baby radishes (air fry them whole)
Store in the fridge for up to 3 days. Reheat in the air fryer for 2-3 minutes or in the oven (200C / 400F) for 5 minutes.
