Ingredients
Method
- Prep the zucchini: Wash and trim the ends. Slice each zucchini into 3-inch sticks, about the width of your finger. Aim for even sizes so they cook uniformly.
- Dry thoroughly: Spread the sticks on a towel, sprinkle lightly with salt, and let sit 10 minutes. Pat very dry. This step is key for crisp fries.
- Set up the coating station: In one shallow bowl, whisk the eggs with a pinch of salt and pepper. In another, mix almond flour, Parmesan, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, 1 teaspoon paprika, 1/2 teaspoon salt, and a few grinds of pepper.
- Coat the fries: Working in batches, dip zucchini sticks in egg, let excess drip, then roll in the almond-Parmesan mixture, pressing gently so it adheres. Place on a parchment-lined baking sheet or air-fryer tray.
- Spritz with oil: Lightly spray the coated fries with avocado or olive oil. This helps browning and crunch.
- To bake: Preheat oven to 425°F (220°C). Arrange fries in a single layer with space between. Bake 18–22 minutes, flipping once at the 12-minute mark, until golden and crisp at the edges.
- To air-fry: Preheat air fryer to 390°F (200°C). Cook in a single layer for 10–12 minutes, shaking or flipping halfway, until deeply golden. Work in batches to avoid crowding.
- Season and serve: Sprinkle with a pinch of salt while hot. Add a squeeze of lemon if you like brightness. Serve immediately with your favorite keto-friendly dip.

How to Store

- Reheat: Best in an air fryer at 375°F (190°C) for 4–6 minutes or in a hot oven for 8–10 minutes.
Avoid the microwave if you want to keep them crisp.
- Freeze: Not ideal once cooked. For make-ahead, coat the raw sticks and freeze on a tray. Transfer to a bag once solid, then bake or air-fry from frozen, adding a few extra minutes.

FAQ
Are zucchini fries actually crispy without breadcrumbs?
Yes. The combo of almond flour and grated Parmesan crisps up beautifully, especially with a light oil spritz and proper drying of the zucchini. Air-frying gives the crispiest finish, but the oven works great too.
Can I make these dairy-free?
You can.
Replace Parmesan with finely ground pork rinds or a dairy-free Parmesan-style crumble. Add extra seasoning to make up for the missing cheese flavor.
What sauces go well with keto zucchini fries?
Try garlic aioli, sugar-free marinara, ranch, blue cheese, or a quick spicy mayo (mayo plus hot sauce and lemon). Keep an eye on carbs in store-bought sauces.
How many carbs are in a serving?
Exact numbers vary by zucchini size and coating used, but a typical serving lands around 4–6 net carbs.
For the most accurate count, plug your exact ingredients into a nutrition calculator.
Can I prep these ahead?
Yes. Cut and dry the zucchini, then store sticks in the fridge on a paper towel-lined container for up to 24 hours. You can also coat and freeze them raw, then cook from frozen.
Is coconut flour a good substitute for almond flour?
Not in the same amount.
Coconut flour is highly absorbent and won’t create the same texture. If you need nut-free, finely crushed pork rinds are a better swap.
Do I need to peel the zucchini?
No. The peel helps the sticks hold their shape and adds nutrients and color.
Just wash well and trim the ends.

Keto Crispy Zucchini Fries deliver big fry energy with clean, low-carb ingredients and simple steps. With a crunchy almond-Parmesan crust and flexible cooking methods, they’re easy to make and easy to love.
