Air Fryer Low Carb Chips - Crispy, Fast, and Satisfying
Ingredients
- 2 medium zucchinis or 1 large jicama or 10–12 large radishes (choose one; see Alternatives)
- 1–1½ tablespoons avocado oil or olive oil
- 1 teaspoon fine sea salt, plus more to taste
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika (or regular paprika)
- ¼ teaspoon black pepper
- Optional: ¼ teaspoon onion powder, pinch of chili powder, or 1 tablespoon grated Parmesan for extra savoriness
Instructions
- Prep the vegetable base. Choose your low-carb “chip.” For zucchini, trim ends and slice into very thin rounds (about 1/16–1/8 inch). For jicama, peel the thick skin first, then cut into thin rounds. For radishes, trim ends and slice thinly. A mandoline gives even slices and better crisping.
- Dry the slices well. Spread slices on a clean kitchen towel or paper towels. Pat thoroughly to remove surface moisture. This is key for crisp chips, especially with zucchini.
- Toss with oil and spices. In a large bowl, combine slices, oil, salt, garlic powder, smoked paprika, and pepper. Toss gently until everything is lightly coated. Do not drench—too much oil leads to soggy chips.
- Preheat the air fryer to 325°F (160°C). A slightly lower temperature helps dehydrate first, then crisp without burning.
- Arrange in a single layer. Add slices to the air fryer basket in an even, single layer with minimal overlap. Work in batches for best results.
- Air fry and flip. Cook for 8–10 minutes, shaking or flipping halfway. Timing varies by thickness and vegetable: Zucchini: 8–12 minutes total; watch closely in the last 3 minutes.
- Radishes: 10–14 minutes total.
- Jicama: 12–18 minutes total; it’s denser and may take longer.
- Finish and dry crisp. When chips are lightly browned and crisping at the edges, remove them to a wire rack. They’ll continue to crisp as they cool. If some slices are still soft, return them to the air fryer for 1–2 more minutes.
- Taste and season. Sprinkle with a touch more salt while warm, if needed. Add optional Parmesan now for a light melt and extra crunch.
- Cool completely. Let chips cool 5–10 minutes on the rack to lock in crunch before storing or serving.

Storage Instructions
- Room temperature: Store fully cooled chips in an airtight container for up to 2 days. Slip in a small piece of paper towel to absorb moisture.
- Re-crisp: If they soften, air fry at 300°F (150°C) for 2–3 minutes, then cool again.
- Avoid the fridge: Refrigeration adds moisture and can make chips limp.
Why This is Good for You
- Lower in carbs than potatoes: Veggies like zucchini, radishes, and jicama have fewer net carbs, making them a smart swap for chip cravings.
- Better fats, minimal oil: A small amount of avocado or olive oil adds flavor and helps absorb fat-soluble nutrients without deep-frying.
- Fiber and micronutrients: You’ll get fiber, vitamin C, potassium, and antioxidants, especially from radishes and jicama.
- Less processed: No fillers, no added sugars, and you control the sodium and spices.
What Not to Do
- Don’t crowd the basket. Overlapping slices steam instead of crisp.
Single layer is non-negotiable.
- Don’t skip drying. Wet slices equal soggy chips. Pat them down before seasoning.
- Don’t crank the heat too high. High temps can burn the edges while the centers stay chewy.
- Don’t over-oil. More oil does not mean more crunch. Use just enough to lightly coat.
- Don’t walk away at the end. The last 2–3 minutes decide crispy vs. burnt.
Keep an eye on them.
Alternatives
- Vegetable swaps:
- Turnips: Mild flavor, good crunch, low carb.
- Kohlrabi: Slightly sweet, crisp, excellent for chips.
- Eggplant: Slice very thin; becomes delicate and crisp with a savory bite.
- Seasoning ideas:
- Salt & Vinegar: Toss slices with 1 teaspoon vinegar after air frying, then re-crisp for 1–2 minutes.
- BBQ-Style: Smoked paprika, garlic powder, onion powder, pinch of sweetener, chili powder, and salt.
- Ranch: Dried dill, parsley, garlic powder, onion powder, salt, and pepper.
- Cheesy: Grated Parmesan or nutritional yeast added in the last 2 minutes.
- Dips that fit low carb: Guacamole, Greek yogurt ranch, spicy mayo, salsa verde, or whipped feta.
- Oil options: Avocado oil for high-heat stability, olive oil for a fruitier note, or ghee for buttery flavor.
FAQ
What’s the lowest-carb veggie for chips?
Radishes and zucchini are among the lowest in net carbs per serving. Jicama and kohlrabi are slightly higher but still much lower than potatoes.
How do I get them really crispy?
Slice evenly and thin, dry the slices thoroughly, cook in a single layer at 325°F, and cool on a wire rack. If needed, run a quick 1–2 minute re-crisp at the end.
Can I make these without a mandoline?
Yes.
Use a sharp knife and aim for consistent thin slices. If your slices vary in thickness, pull the thinner ones early as they crisp faster.
Why are my chips soggy?
Too much moisture, too much oil, or basket crowding are the usual culprits. Pat dry, use a light oil coat, and work in batches.
Do I need to peel the veggies?
Peel jicama, kohlrabi, and turnips for best texture.
Zucchini and radishes don’t need peeling.
Can I bake these instead of air frying?
Yes. Bake at 325°F (160°C) on parchment-lined sheets in a single layer for 20–35 minutes, flipping halfway. Watch closely in the final minutes.
How do I season them without adding carbs?
Use salt, pepper, herbs, and spices.
If using blends, check labels for added sugar or starches.
Are these kid-friendly?
Usually, yes. Start with simple salt and a little paprika or Parmesan. Serve with a favorite dip for extra appeal.
Can I make a big batch?
You can, but plan on multiple batches.
Keep finished chips on a rack while you cook the rest, then do a 2-minute group re-crisp before serving.
What’s the best way to keep them crunchy?
Cool completely, store airtight at room temp, and avoid humidity. Re-crisp briefly in the air fryer if needed.
