These Keto Zucchini Parmesan Crisps are the kind of snack you make once and then keep making every week. They’re salty, cheesy, crisp on the edges, and perfect when you want something crunchy without the carbs. They also come together fast with simple ingredients you probably have on hand.
Serve them with marinara, ranch, or enjoy them straight off the tray. They work as an appetizer, a side, or a movie-night bite that won’t throw off your goals.
Ingredients
Method
- Prep the oven and pans: Heat the oven to 425°F (220°C). Line two baking sheets with parchment paper and lightly spray or brush with olive oil to prevent sticking.
- Slice the zucchini: Wash and dry the zucchini. Slice into 1/4-inch rounds. Try to keep them even so they bake at the same rate.
- Draw out moisture: Lay slices on a clean towel or paper towels. Sprinkle lightly with salt and let sit for 10–15 minutes. Blot the tops thoroughly to remove excess water. This step makes them crisp, not limp.
- Make the coating: In a shallow bowl, combine almond flour, Parmesan, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix well to break up any clumps.
- Beat the egg: In a separate shallow bowl, beat the egg until smooth. This will help the coating stick to the zucchini.
- Coat the slices: Dip each zucchini round in egg, let the excess drip off, then press into the Parmesan-almond mixture to coat both sides. Place on the prepared baking sheets, spacing them out so they don’t steam each other.
- Oil for crispiness: Lightly spray or brush the tops with olive oil. This boosts browning and crunch.
- Bake: Bake for 12–14 minutes, then flip each slice carefully. Bake another 8–10 minutes, or until golden brown with crisp edges.
- Optional broil: For extra crunch, broil on high for 1–2 minutes at the end. Watch closely to avoid burning.
- Serve: Let cool 2–3 minutes to set the crust. Serve warm with your favorite dip or sprinkle with more Parmesan and a pinch of red pepper flakes.
Why This Recipe Works
Most zucchini snacks turn soggy, but this recipe solves that. Salting and blotting the zucchini pulls out excess moisture, which helps the coating crisp up. A mix of almond flour and grated Parmesan creates a golden, crunchy crust without breadcrumbs.
A touch of egg wash helps everything stick. High oven heat finishes the job, so you get crispy discs with a tender center and real flavor in every bite.

Storage Instructions
These are best fresh, but you can store leftovers.
Cool completely, then place in an airtight container with parchment between layers. Refrigerate for up to 3 days. To reheat, use an air fryer at 375°F (190°C) for 3–5 minutes or a 400°F (205°C) oven for 6–8 minutes. Avoid the microwave, which softens the coating. You can also freeze them in a single layer, then transfer to a freezer bag.
Reheat from frozen in an air fryer or hot oven until crisp.
Health Benefits
- Low in carbs: Almond flour and Parmesan keep the coating keto-friendly while still giving you that classic crunch.
- High in protein and fat: Parmesan and egg offer satisfying protein and healthy fats that help keep you full.
- Micronutrient boost: Zucchini adds vitamin C, potassium, and fiber. It’s a light, nutrient-dense base that pairs well with bold flavors.
- Gluten-free: No breadcrumbs, no problem. This recipe works for gluten-free eaters too.
Common Mistakes to Avoid
- Skipping the salting step: If you don’t draw out moisture, your crisps can turn soggy.
- Using powdered Parmesan: It doesn’t melt the same way and can taste chalky.
Go for freshly grated or good-quality pre-grated.
- Cutting uneven slices: Thin slices burn fast while thicker ones stay soft. Aim for consistent 1/4-inch rounds.
- Crowding the pan: Overlapping slices steam instead of crisp. Use two sheets or bake in batches.
- Too low heat: A hot oven is key to a golden, crunchy finish.
Variations You Can Try
- Italian Herb: Add 1 teaspoon dried Italian seasoning and a pinch of red pepper flakes to the coating.
- Everything Bagel: Mix 1 tablespoon everything bagel seasoning into the Parmesan-almond blend and skip extra salt.
- Lemony Garlic: Add 1 teaspoon lemon zest and extra garlic powder for brightness, and finish with a squeeze of lemon.
- Spicy Chipotle: Swap smoked paprika for chipotle powder and serve with a lime-yogurt dip.
- Pesto Drizzle: After baking, drizzle with a little pesto and top with shaved Parmesan.
- Air Fryer Method: Cook at 390°F (200°C) for 8–10 minutes, flipping halfway.
Work in batches so they crisp evenly.
FAQ
Can I use coconut flour instead of almond flour?
You can, but use less. Coconut flour is very absorbent and can turn the coating dry. If you try it, start with 2–3 tablespoons mixed with the Parmesan and adjust as needed.
Almond flour gives a more classic texture.
How do I keep the coating from falling off?
Dry the zucchini well after salting, dip in egg, and press firmly into the coating. Place them on parchment and don’t move them until it’s time to flip. A light oil spray also helps the crust set.
What kind of Parmesan should I use?
Use freshly grated or a high-quality pre-grated Parmesan with a fine shred.
Avoid the powder in a can; it doesn’t melt properly and won’t crisp the same way.
Can I make these dairy-free?
Yes. Replace Parmesan with a dairy-free hard “Parmesan-style” cheese or use a mix of almond flour and finely ground pork rinds. Note that the flavor will change slightly, but the texture can still be crisp.
Are these kid-friendly?
Usually, yes.
They taste like cheesy chips with a mild zucchini center. If your kids are spice-sensitive, skip the smoked paprika and serve with marinara or ranch.
How many carbs are in a serving?
Exact numbers vary with brands and slice size, but a typical serving (about 10–12 crisps) is roughly 4–6g net carbs. Check your ingredient labels and portion size for the most accurate count.
Can I prepare them ahead?
You can slice, salt, and blot the zucchini a few hours in advance.
Keep them in the fridge wrapped in paper towels. Coat and bake just before serving for the best crunch.
