Introduction
Keto zucchini fries are a flavorful, low-carbohydrate alternative to traditional potato fries. They have a crispy exterior, a tender interior, and pair well with many dipping sauces. Because zucchini naturally contains more water than potatoes, the secret to achieving crisp fries lies in removing excess moisture, using a well-seasoned coating, and cooking at the proper temperature. This recipe explains every step in detail so you can consistently make excellent zucchini fries whether you bake them or cook them in an air fryer.
Preparation Time
- Preparation: 25 minutes
- Resting time: 20 minutes
- Cooking: 20–30 minutes
- Total time: About 1 hour 15 minutes
Servings: 4
Ingredients
For the zucchini fries:
- 2 medium zucchini
- 1 cup finely grated Parmesan cheese
- 1 cup almond flour
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon paprika
- 1 teaspoon Italian seasoning
- ½ teaspoon black pepper
- 1 teaspoon salt
- ½ teaspoon cayenne pepper (optional)
- 2 large eggs
- 1 tablespoon heavy cream
- 2 tablespoons olive oil or avocado oil
- Cooking spray or additional oil for greasing
Optional additions:
- 2 tablespoons finely grated cheddar cheese
- 1 tablespoon nutritional yeast
- ½ teaspoon dried oregano
- ½ teaspoon dried basil
- ½ teaspoon smoked paprika
Equipment
- Sharp knife
- Cutting board
- Mixing bowls
- Baking sheet
- Parchment paper
- Cooling rack (recommended)
- Whisk
- Measuring cups and spoons
- Paper towels
- Wire rack for cooling
Step 1: Selecting the Best Zucchini
Choose zucchini that are:
- Firm
- Bright green
- Smooth-skinned
- Medium-sized
- Free from soft spots
- Heavy for their size
Avoid oversized zucchini because they contain larger seeds and more water, which can make the fries soggy.
Step 2: Washing
Wash each zucchini thoroughly under cool running water.
Scrub gently with your hands or a vegetable brush to remove dirt.
Dry completely with clean kitchen towels.
Step 3: Cutting
Trim both ends.
Slice each zucchini in half lengthwise.
Slice each half into long strips about ½ inch thick.
Try to keep every fry approximately the same size so they cook evenly.
Step 4: Removing Moisture
Lay the zucchini strips on paper towels.
Sprinkle lightly with salt.
Allow them to rest for 20 minutes.
The salt draws moisture out of the zucchini.
After resting, gently press each strip with additional paper towels.
The drier the zucchini, the crispier the finished fries.
Step 5: Prepare the Coating
In a large bowl combine:
- Parmesan cheese
- Almond flour
- Garlic powder
- Onion powder
- Paprika
- Italian seasoning
- Black pepper
- Remaining salt
- Cayenne pepper if using
- Optional herbs and nutritional yeast
Mix thoroughly until every ingredient is evenly distributed.
Step 6: Egg Wash
In another bowl whisk together:
- Eggs
- Heavy cream
Whisk until smooth.
The egg mixture helps the coating stick to the zucchini.
Step 7: Coat the Fries
Dip each zucchini strip into the egg mixture.
Allow excess egg to drip off.
Roll the strip in the almond flour mixture.
Press gently so the coating adheres firmly.
Place the coated fry onto a plate.
Repeat until every strip has been coated.
Step 8: Preparing the Baking Tray
Preheat oven to 425°F (220°C).
Line a baking tray with parchment paper.
Lightly grease the paper.
Arrange fries in a single layer.
Leave small spaces between each fry.
Avoid stacking.
Crowding traps steam and reduces crispiness.
Step 9: Baking
Bake for 12 minutes.
Flip every fry carefully.
Bake another 10–15 minutes.
Watch closely during the last few minutes.
The coating should become golden brown.
The edges should appear crisp.
If additional browning is desired, broil for 1–2 minutes while watching continuously.
Air Fryer Instructions
Preheat the air fryer to 400°F (200°C).
Lightly spray the basket.
Arrange fries in one layer.
Cook for 10 minutes.
Turn the fries.
Cook another 6–8 minutes.
Repeat with remaining batches.
Pan-Frying Option
Heat a thin layer of avocado oil in a skillet.
Cook over medium heat.
Place fries carefully into the hot oil.
Cook approximately 3–4 minutes per side.
Transfer to paper towels after cooking.
Making Them Extra Crispy
Use freshly grated Parmesan instead of pre-shredded.
Always dry the zucchini well.
Do not skip the salting step.
Avoid overcrowding.
Use a wire rack on the baking sheet if available.
Serve immediately after cooking.
