Ingredients
Method
- Prep the zucchini: Wash and dry thoroughly. Slice into 1/8–1/4-inch rounds. Thinner slices get crisper; thicker ones are slightly more tender.
- Draw out moisture: Lay slices on a clean towel or paper towels. Sprinkle lightly with salt. Let sit 10–15 minutes, then gently pat dry. This step is key for crunch.
- Preheat and line: For oven, heat to 425°F (220°C) and line a baking sheet with parchment. For air fryer, heat to 375°F (190°C) and lightly oil the basket or use perforated parchment.
- Mix the coating: In a bowl, combine Parmesan, almond flour, garlic powder, onion powder, smoked paprika, salt, and pepper.
- Oil the slices: Toss zucchini rounds with olive oil until lightly coated. Don’t drench them—just a slick surface helps the coating stick.
- Coat for crispness: Press each slice into the Parmesan mixture, coating both sides. Shake off excess and set on the prepared sheet or air fryer basket in a single layer.
- Bake or air fry: Oven: Bake 15–20 minutes, flipping halfway, until golden and crisp at the edges.
- Air fryer: Cook 8–12 minutes, shaking or flipping at the halfway mark. Work in batches to avoid crowding.
- Finish and serve: Let chips cool 2–3 minutes to firm up. Sprinkle with a touch more Parmesan or parsley. Add a squeeze of lemon if you like. Serve with your favorite low-carb dip.
What Makes This Recipe So Good
- Low-carb and satisfying: Zucchini keeps the carbs low while still giving that chip-like bite.
- Big flavors, simple ingredients: Garlic, Parmesan, and a few pantry spices do the heavy lifting.
- Extra crisp factor: A light almond flour coating helps the cheese cling and turn golden.
- Flexible cooking methods: Bake or air fry—both deliver crunch with minimal oil.
- Quick prep, quick cook: Slice, season, and bake. Great for weeknights or last-minute snacks.

Keeping It Fresh
These are best the day you make them, but you can keep leftovers in an airtight container in the fridge for 2–3 days.
To re-crisp, warm them in a 375°F (190°C) oven or air fryer for 3–5 minutes. Avoid microwaving—they’ll soften quickly. If you plan to make ahead, slightly underbake, then finish right before serving to keep the edges snappy.
Health Benefits
- Low in carbs: Zucchini is naturally low-carb and keto-friendly, making it a great stand-in for chips.
- Fiber and micronutrients: You’ll get fiber, vitamin C, potassium, and antioxidants from zucchini’s skin and flesh.
- Protein and calcium: Parmesan adds a bump of protein and calcium without many carbs.
- Healthy fats: Olive oil supports satiety and helps you absorb fat-soluble nutrients.
Common Mistakes to Avoid
- Skipping the salting step: Excess moisture leads to soggy chips.
The quick salt-and-dry trick makes a huge difference.
- Using thick shreds of Parmesan: Finely grated (powdery) Parmesan clings better and crisps more evenly.
- Overcrowding the pan: Airflow is everything. Give each slice space or cook in batches.
- Too much oil: A heavy pour will drown the coating. Light and even is the goal.
- Not flipping: Turning the chips halfway promotes even browning and crunch.
Recipe Variations
- Spicy kick: Add 1/4–1/2 teaspoon crushed red pepper flakes or cayenne to the coating.
- Herb lover’s blend: Swap smoked paprika for 1 teaspoon Italian seasoning or dried basil and oregano.
- Pork rind crunch: Replace half the almond flour with crushed pork rinds for extra crisp, zero-carb oomph.
- Lemon-garlic: Zest one lemon into the coating and finish with a squeeze of juice.
- Dairy-free: Use a dairy-free Parmesan-style cheese and rely more on almond flour and spices.
Texture will be slightly softer but still tasty.
- Chipotle-parm: Swap smoked paprika for chipotle powder and add a pinch of cumin.
FAQ
How do I keep the chips from getting soggy?
Draw out moisture with the quick salting step, pat dry well, and avoid overcrowding. Use finely grated Parmesan and a light hand with oil. Reheat in the oven or air fryer to re-crisp if needed.
Can I slice the zucchini ahead of time?
Yes, but store slices between paper towels in a sealed container to prevent moisture buildup.
Pat dry again before coating and cooking.
What thickness should I slice them?
For the crunchiest chips, aim for 1/8 inch. For a slightly meatier bite, go up to 1/4 inch, but expect a touch less crisp.
Do I need to peel the zucchini?
No. Keep the skin on for color, texture, and extra nutrients.
Just wash and dry well.
Can I use grated Parmesan from a bag?
Yes, but the best crisp comes from very finely grated or shelf-stable Parmesan. If yours is coarser, pulse it in a food processor for a finer texture.
What dips work well and stay keto?
Ranch, garlic aioli, Caesar, or a no-sugar-added marinara all pair nicely. You can also mix Greek yogurt (or keto-friendly mayo) with lemon and dill for a quick sauce.
How do I prevent sticking?
Use parchment paper in the oven or lightly oil your air fryer basket.
Let the chips set for a minute before flipping so the crust doesn’t tear.
Can I make these without almond flour?
Absolutely. Use all Parmesan for coating, or swap almond flour with crushed pork rinds for extra crunch. Adjust salt if using pork rinds, as they can be salty.
Are these freezer-friendly?
They’re best fresh.
Freezing adds moisture and can soften the crust. If you must freeze, re-crisp in a hot oven or air fryer before serving.
How do I scale the recipe?
Double or triple as needed, but cook in batches to avoid crowding. Keep finished chips on a wire rack in a warm oven (around 200°F/95°C) while you finish the rest.
