Peel and slice turnips to 1/2. Add them to a large bowl and toss with 2 tbsp of cornstarch to lightly coat.
In a small bowl add 2 tbsp olive oil, 1 tsp garlic powder, 1 tsp paprika, 1/2 tsp onion powder, 1/2 tsp salt and 1/4 tsp black pepper. Mix to combine and pour over turnip sticks. Mix well to evenly coat the turnips.
Place the turnip pieces in the air-fryer basket and then on top of the baking sheet or likewise in the oven. Air-fry or bake for 20-25 minutes. Turn halfway through and continue cooking until turnip fries are softened and crispy on the edges. Remove from the air-fryer or oven.
While the turnip fries are cooking in a small bowl add 1/2 cup of smooth cottage cheese, 1/4 cup salsa, 1/2 tsp garlic powder and 1/4 tsp chipotle chilli powder. Mix well. Serve as a dip for turnip fries.
If using a convection oven you may need to increase the cooking time by about another 5 minutes.
Can't find smooth cottage cheese? Just add the dip ingredients to a small blender and blend until smooth.
Turnip fries should be consumed right away so they remain as crispy as possible and any unused dip can be stored in a tightly sealed container in the fridge for up to 5 days.
