Ingredients
- 2 medium zucchini, sliced into thin rounds (about 1/8 inch thick)
- 1 large egg, beaten
- 1/2 cup almond flour
- 1/3 cup grated Parmesan cheese (the fine, powdery kind works best)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon smoked paprika (or regular paprika)
- 1/4 to 1/2 teaspoon kosher salt, to taste
- 1/4 teaspoon black pepper
- Avocado or olive oil spray, for the air fryer basket and tops
- Optional dips: ranch, garlic aioli, sugar-free marinara, or Greek yogurt dip
Instructions
- Prep the zucchini. Wash and dry the zucchini well.Slice into thin rounds, aiming for consistent thickness so they cook evenly. Pat the slices dry with paper towels to remove extra moisture.
- Set up your coating stations. In one shallow bowl, beat the egg. In a second bowl, mix almond flour, Parmesan, garlic powder, onion powder, paprika, salt, and pepper until evenly combined.
- Preheat the air fryer. Set it to 375°F (190°C).Lightly spray the basket with oil so the coating doesn’t stick.
- Coat the slices. Dip each zucchini round in the egg, let the excess drip off, then press into the almond-Parmesan mixture to coat both sides. Place coated slices on a plate while you work.
- Arrange in the basket. Lay the slices in a single layer in the air fryer. Don’t overlap.Lightly mist the tops with oil spray for extra crispness.
- Air fry until crisp. Cook for 7–9 minutes, then flip and cook another 4–6 minutes. Chips are done when golden and crisp around the edges. Thinner slices cook faster; keep an eye on the first batch to learn your ideal timing.
- Season and serve. Sprinkle with a pinch of salt while hot if needed.Serve right away with your favorite dip.
- Work in batches. Repeat with remaining slices. Keeping a single layer is key to getting them crispy.

Storage Instructions
These are best fresh, but you can store leftovers. Let the chips cool completely, then place them in an airtight container lined with paper towels.
Refrigerate for up to 2 days. To re-crisp, air fry at 360°F (182°C) for 3–5 minutes or until crunchy again. Avoid the microwave—it makes them soft.
Why This is Good for You
- Low in carbs: Almond flour and Parmesan keep net carbs low compared to breaded chips or crackers.
- Healthy fats and protein: The coating offers satiating fat and a bump of protein, helping you feel full longer.
- Veggie forward: Zucchini brings fiber, potassium, and vitamins with minimal calories.
- Less oil: Air frying reduces overall oil use while still giving you that crispy texture.
Common Mistakes to Avoid
- Skipping the dry step: Wet zucchini won’t crisp well.
Pat slices dry before coating.
- Overcrowding the basket: Chips need space for hot air to circulate. Cook in batches for even browning.
- Too-thick slices: Thick rounds turn soft before the coating crisps. Aim for about 1/8 inch.
- Not preheating: A hot air fryer helps the coating set quickly and crisp better.
- Heavy oiling: A light mist is enough.
Too much oil can make the coating soggy.
Recipe Variations
- Classic ranch: Add 1 teaspoon ranch seasoning to the almond-Parmesan mix for a tangy kick.
- Spicy chipotle: Swap smoked paprika for chipotle powder and add a pinch of cayenne.
- Everything bagel: Stir 1 teaspoon everything bagel seasoning into the coating mixture.
- Italian style: Add 1 teaspoon Italian seasoning and serve with warm sugar-free marinara.
- Pork rind crunch: Replace half the almond flour with finely crushed pork rinds for extra crunch and even fewer carbs.
- Dairy-free option: Skip Parmesan and add 1–2 tablespoons nutritional yeast to the almond flour. It won’t be identical, but it gives a savory flavor.
FAQ
How thin should I slice the zucchini?
Aim for about 1/8 inch thick. Thinner slices get crispier and cook faster.
Use a mandoline for consistency if you have one, but a sharp knife works too.
Can I make these without almond flour?
Yes. Replace almond flour with crushed pork rinds for a nut-free, ultra-crispy option. You can also use coconut flour, but use less (about 1/4 cup) because it absorbs more moisture and can turn dry.
Why are my chips soggy?
Too much moisture or overcrowding is usually the problem.
Pat the slices dry, coat evenly, and cook in a single layer. Flip halfway and add a quick oil mist if the coating looks dry. Also make sure your air fryer is fully preheated.
What dips go well with these?
Ranch, chipotle mayo, garlic aioli, sugar-free marinara, or a lemony Greek yogurt dip are all great.
For a simple option, mix mayonnaise, lemon juice, and a pinch of garlic powder.
Can I bake them instead of air frying?
Yes. Place coated slices on a parchment-lined sheet, mist lightly with oil, and bake at 425°F (218°C) for 15–20 minutes, flipping once. They won’t be quite as crisp as air fried, but still tasty.
Do I need to salt the zucchini first?
Not required, but you can.
Lightly salt the slices and let them sit for 10–15 minutes, then blot dry. This draws out extra moisture and can boost crispness, especially if your zucchini is very fresh and watery.
Can I make them in advance?
You can slice and coat the zucchini a few hours ahead and keep them on a tray in the fridge. Air fry just before serving for the best texture.
Reheating works, but fresh is crispest.
How do I keep the coating from falling off?
Dry the zucchini well, shake off excess egg, and press the slices firmly into the coating. A light oil mist on top helps the crust set. Flip gently with tongs halfway through.
Are these kid-friendly?
Yes.
Keep the spices mild and serve with a favorite dip. Many kids enjoy the crunchy texture and cheesy flavor.
What’s the best Parmesan to use?
Finely grated or powdered Parmesan clings best and crisps nicely. Shredded Parmesan can work, but it tends to melt in strands and doesn’t coat as evenly.
In Conclusion
Air Fryer Keto Zucchini Chips are the kind of snack that makes low-carb eating feel easy.
They’re quick to prepare, satisfyingly crunchy, and endlessly customizable with your favorite seasonings. Serve them hot with a good dip, and you’ll forget all about store-bought chips.
