Keto Air Fryer Zucchini Fries (Crispy, 4g Net Carbs)

These keto air fryer zucchini fries are golden, crispy, and coated in a savory blend of almond flour, parmesan, and Italian herbs — with only about 4 grams of net carbs per serving. If you’ve been missing french fries since going low carb, this is the recipe that fills that gap. They cook in just 10 minutes, there’s no deep frying, and the coating crisps up beautifully without a single breadcrumb.

I’ve made zucchini every way you can imagine in the air fryer — from cheesy zucchini pizza bites to crunchy parmesan zucchini chips — and these fries are the recipe my family requests most. The fry shape gives you more crispy coating in every bite, and they’re sturdy enough to dunk into your favorite low-carb sauce.

Why You’ll Love This Recipe

• Truly crispy without breadcrumbs. The combination of almond flour and finely grated parmesan creates a coating that browns and crisps in the air fryer’s circulating heat. The parmesan is the secret — as it melts, it forms a golden crust that regular flour can’t match.
• Fast enough for weeknights. From cutting board to table in about 20 minutes. There’s no oil to heat, no splatter to clean, and no standing over a frying pan.
• Genuinely low carb. Each serving comes in around 4g net carbs, which makes these an easy fit for keto, low-carb, and gluten-free diets. Serve them alongside my keto air fryer chicken tenders and you have a full “fast food” dinner that keeps you in ketosis.

Ingredients You’ll Need

Here’s a quick look at what goes into these zucchini fries. The full amounts are in the recipe card at the bottom of the post.

• Zucchini — Two medium zucchini, about 6 to 8 inches long. Smaller zucchini have fewer seeds and less water, which means crispier fries.
• Almond flour — Use blanched, finely ground almond flour (not almond meal) for the smoothest, most even coating.
• Grated parmesan cheese — The finely grated kind, which clings to the egg wash and crisps as it cooks. Freshly grated from a block works even better than the shelf-stable canister.
• Eggs — Two large eggs, whisked, to help the coating stick.
• Italian seasoning, garlic powder, salt, and black pepper — A simple seasoning blend that lets the parmesan shine.
• Olive oil spray — A light spray before cooking is what takes the coating from pale to golden.

How to Make Keto Zucchini Fries in the Air Fryer

Step 1: Cut the zucchini into fries. Slice each zucchini in half crosswise, then cut each half lengthwise into sticks about 1/2 inch thick — roughly the size of a steak fry. Try to keep them uniform so they all finish cooking at the same time. Pat the sticks very dry with paper towels; this is the single most important step for crispy fries.

Step 2: Set up your breading station. In a shallow bowl, whisk the eggs. In a second shallow bowl, stir together the almond flour, grated parmesan, Italian seasoning, garlic powder, salt, and pepper.

Step 3: Coat the zucchini. Working a few sticks at a time, dip the zucchini into the egg wash, let the excess drip off, then roll them in the almond flour mixture, pressing gently so the coating adheres on all sides.

Step 4: Air fry. Arrange the coated fries in a single layer in the air fryer basket, leaving space between each one so the hot air can circulate. Spray lightly with olive oil. Air fry at 400 degrees F for 8 to 10 minutes, flipping halfway through, until golden brown and crisp. Cook in batches if needed — crowding the basket is the fastest way to end up with soggy fries.

Pro Tips for the Crispiest Zucchini Fries

• Dry the zucchini twice. Zucchini is over 90% water. Pat the sticks dry after cutting, and again just before dipping them in the egg. For extra insurance, sprinkle the sticks with a little salt, let them sit for 10 minutes, then blot away the moisture that beads up.
• Don’t skip the oil spray. Almond flour won’t brown well without a little fat on the surface. One light, even spray makes the difference between pale and golden.
• Single layer only. If the fries touch or overlap, they steam instead of crisp. Two smaller batches beat one crowded one every time.
• Use one “wet hand” and one “dry hand” when breading. It keeps the coating out of clumps and off your fingers.

Coating Variations

The almond flour and parmesan coating is my go-to, but you have options if you’re avoiding nuts or want to change the flavor:

• Crushed pork rinds — The crunchiest keto option of all, and zero carbs. Swap them in 1:1 for the almond flour.
• Coconut flour — Works in a pinch, but use about one-third the amount, since coconut flour is far more absorbent than almond flour.
• Nutritional yeast — A dairy-free way to get that savory, cheesy flavor if you’re skipping the parmesan.
• Spicy — Add 1/4 teaspoon of cayenne or a teaspoon of smoked paprika to the coating.

What to Serve With Keto Zucchini Fries

These fries were made for dipping. Ranch dressing, garlic aioli, sugar-free ketchup, and marinara (in moderation) are all great low-carb choices. For a fun keto appetizer spread, put them out with a batch of keto air fryer corn dogs — it’s game-day food that nobody will guess is low carb.

As a side dish, they pair perfectly with almost any protein: grilled steak, air fryer salmon, burgers in lettuce wraps, or those crispy keto chicken tenders I mentioned earlier. And if zucchini season has left you with more squash than you know what to do with, my parmesan crusted zucchini crisps are another family favorite that uses it up fast.

Storing and Reheating

Refrigerator: Let the fries cool completely, then store them in an airtight container lined with a paper towel for up to 3 days. The paper towel absorbs moisture and helps preserve the coating.

Reheating: The air fryer brings them right back to life — 3 to 4 minutes at 375 degrees F and they’re crispy again. Skip the microwave, which turns the coating soft.

Freezing: I don’t recommend freezing cooked zucchini fries; zucchini releases too much water as it thaws. If you want to prep ahead, you can bread the raw fries, freeze them in a single layer on a sheet pan, then bag them. Air fry straight from frozen, adding 2 to 3 minutes to the cook time.

Frequently Asked Questions

How many carbs are in keto zucchini fries? About 4g net carbs per serving with the almond flour and parmesan coating. The exact number depends on the size of your zucchini, but this is a fraction of the roughly 40g of carbs in a serving of regular french fries.

Why did my zucchini fries turn out soggy? Almost always one of three things: the zucchini wasn’t patted dry, the basket was overcrowded, or they sat too long after cooking. Dry the sticks well, cook in a single layer, and serve them hot.

Can I use large garden zucchini? Yes — just scoop out the seedy center before cutting your sticks, since the core is the wateriest part. Cut oversized zucchini into slightly thinner sticks so they cook through in the same time.

Can I make these in the oven instead? You can. Bake them on a wire rack set over a sheet pan at 425 degrees F for about 20 to 25 minutes, flipping once. They won’t be quite as crispy as the air fryer version, but they’re still delicious.

Can I make these ahead of time? They’re best fresh, but you can cut and coat the zucchini up to a few hours ahead and keep it in the refrigerator until you’re ready to air fry.
