If you're missing the satisfying crunch of potato chips on your keto diet, these air fryer Parmesan turnip slices will surprise you. This easy side dish or snack is crispy, cheesy, and totally low-carb. In just 10 minutes, you can transform humble turnips into a golden, crunchy delight that satisfies your craving for something savory without knocking you out of ketosis.
Why Turnips Are a Keto-Friendly Potato Swap
Turnips are one of the best root vegetable options for keto. While white potatoes contain around 17g of net carbs per 100g, turnips come in at just 4.6g of net carbs, according to the USDA FoodData Central. They’re rich in vitamin C, fiber, and have a neutral flavor that pairs perfectly with herbs, garlic, and cheese. When sliced thin and cooked in the air fryer, they become tender on the inside and crispy on the edges — just like traditional chips or fries.
Ingredients:
- 1 pound turnip, peeled and sliced
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 3 oz. shredded Parmesan cheese
- 1 tablespoon olive oil
Instructions:
- Peel the turnip and cut it into 1/4-inch thick slices.
- Sprinkle the slices with garlic powder and salt.
- Drizzle with olive oil and toss until well coated.
- Preheat your air fryer to 360°F (182°C).
- Place the turnip slices in the air fryer basket in a single layer. Avoid overcrowding for even crisping.
- Air fry for 10 minutes, flipping halfway through if needed.
- Sprinkle the hot slices with shredded Parmesan immediately after cooking to let the cheese melt slightly and stick.
- Serve hot as a snack or side dish.
