Ingredients

For the Zucchini Fries:

2 medium zucchini (about 1 lb / 450g total)
1 teaspoon kosher salt
½ cup (50g) finely grated Parmesan cheese
½ cup (50g) almond flour
1 teaspoon garlic powder
1 teaspoon smoked paprika
½ teaspoon onion powder
½ teaspoon freshly ground black pepper
¼ teaspoon cayenne pepper (optional)
2 large eggs

For the Cooking Process:

Avocado oil spray or olive oil spray
Optional Binding Aid: 1 tablespoon mayonnaise or sour cream (mixed with eggs)

For Serving:

Sugar-Free Dipping Sauces: Ranch dressing, chipotle mayo, garlic aioli, or no-sugar-added marinara sauce
Lemon wedges
Fresh chopped parsley

Equipment

Baking sheet (for oven) or air fryer basket
Parchment paper or silicone baking mat (for oven)
Three shallow bowls or plates
Wire rack (optional, for extra crispness)
Paper towels

Instructions

Step 1: Prepare the Zucchini (The Crucial Step)

Trim the ends off the zucchini. Cut each zucchini in half crosswise, then cut each half into ½-inch thick fry-like strips. Aim for uniform size for even cooking.
Place the zucchini strips in a colander over a bowl or in the sink. Toss thoroughly with 1 teaspoon of kosher salt. Let them sit for 10-15 minutes.
This step draws out excess moisture, which is the enemy of crispiness. After 15 minutes, use paper towels to pat the zucchini strips extremely dry. Press firmly to remove as much water as possible.

Step 2: Create the Crispy Coating Station

Set up a standard breading station with three shallow dishes.

Bowl 1: Almond flour, grated Parmesan, garlic powder, smoked paprika, onion powder, black pepper, and cayenne (if using). Whisk thoroughly to combine.
Bowl 2: Crack the eggs and whisk them until uniform. For an extra-binding, crispier coat, whisk in 1 tablespoon of mayonnaise or sour cream.
Bowl 3: Leave empty for the coated fries.

Step 3: Coat the Fries

Working in batches, take a handful of the thoroughly dried zucchini strips and toss them in the almond flour-Parmesan mixture. Ensure they are lightly coated on all sides. Shake off excess.
Next, dip each strip into the egg wash, allowing any excess to drip off.
Return the strips to the almond flour-Parmesan mixture for a second, final coat. Press the coating mixture gently onto the zucchini to ensure it adheres well. Place the fully coated fry on a clean plate or directly onto your prepared baking sheet/air fryer basket.
Repeat until all zucchini strips are coated.

Step 4: Cook to Golden Perfection

Oven Method (Recommended for Even Cooking):

Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper and place a wire rack on top (if using). The rack promotes air circulation for maximum crispness.
Arrange coated fries in a single layer on the rack or parchment. Do not crowd them.
Generously spray the fries with avocado oil spray.
Bake for 20-25 minutes, flipping halfway through, until deeply golden brown and crispy.

Air Fryer Method (For Ultimate Crispiness):

Preheat air fryer to 400°F (200°C).
Arrange fries in a single layer in the basket. Do not overcrowd; cook in batches if necessary.
Spray lightly with oil.
Air fry for 10-12 minutes, flipping halfway through, until golden and crisp.

Step 5: Serve Immediately

Remove fries from the oven or air fryer. They are best enjoyed right away while the coating is at its crispiest.
Serve hot with lemon wedges for squeezing and your chosen keto-friendly dipping sauces. Sprinkle with fresh parsley for a pop of color.

Recipe Success Secrets & Troubleshooting

Dry the Zucchini: Do not skip the salting and drying step. This is the single most important factor for achieving crispy, not soggy, fries.
Double Coating: The double-dip method (dry-wet-dry) is essential for creating a substantial, crunchy crust that stays on the zucchini.
Grate Your Own Parmesan: Pre-grated Parmesan often contains anti-caking agents that can prevent proper crisping and browning. A block of Parmesan, finely grated, works best.
Spacing is Key: Whether in the oven or air fryer, ensure fries are not touching. Crowding creates steam, which leads to sogginess.
The Oil Spray: A light but thorough spray of oil is necessary to help the coating brown and crisp. Avocado oil has a high smoke point and neutral flavor.
Not Crispy Enough? Your oven may run cool. Ensure it’s fully preheated. For the oven method, using a wire rack is a game-changer. For the air fryer, ensure you are not overcrowding the basket.
Seasoning Variations: Add ½ teaspoon of Italian seasoning, everything bagel seasoning, or a pinch of chili powder to the coating mix.

Storage & Reheating

Best Enjoyed: Immediately after cooking.
Storage: Store leftover cooled fries in an airtight container in the refrigerator for up to 2 days. They will lose their crispness but still taste good.
Reheating (To Recrisp): Reheat in an air fryer at 375°F (190°C) for 3-5 minutes or in a conventional oven at 400°F (200°C) on a wire rack for 5-8 minutes. Avoid the microwave.

*Note: Nutritional information is an estimate. Sodium content can be adjusted by reducing the salt used in the drying step and choosing a lower-sodium Parmesan. Net carbs are calculated by subtracting dietary fiber from total carbohydrates. These values make this recipe suitable for most low-carb and ketogenic diets. Using a different oil spray or adding more Parmesan will alter the fat content. For a dairy-free version, substitute nutritional yeast for the Parmesan and use a dairy-free mayonnaise in the egg wash.
