Why You’ll Love This Air Fryer Zucchini Keto
The Crunch Factor is Unreal
The main highlight here is that incredible crispy texture that rivals any deep-fried appetizer, but without all the oil and carbs. Each bite delivers a satisfying crunch that gives way to tender zucchini inside. The air fryer creates this perfect contrast that makes these absolutely irresistible.
Budget-Friendly Keto Eating
Making these at home costs a fraction of what you’d pay for keto-friendly appetizers at restaurants. A couple of medium zucchinis cost maybe two dollars, and the coating ingredients are pantry staples. You’re looking at pennies per serving for a snack that tastes like a million bucks.
Flavor Explosion in Every Bite
The combination of nutty parmesan cheese, savory garlic powder, and aromatic Italian herbs creates layers of flavor that make zucchini the star it deserves to be. Add a sprinkle of smoked paprika for depth, and you’ve got a flavor profile that’s anything but boring. If you enjoyed my air fryer Brussels sprouts, you’ll love how these zucchini rounds take vegetables to the next level.
Making these at home means you control the quality of ingredients, the seasoning levels, and you can make them fresh whenever a craving hits. Plus, your kitchen will smell amazing!

Key Ingredients for Air Fryer Zucchini Keto
For the Zucchini:
- 2 medium zucchinis (about 1 pound total)
- 1/2 cup almond flour
- 1/2 cup grated parmesan cheese
- 1 large egg
- 2 tablespoons heavy cream
For the Coating:
- 1 teaspoon garlic powder
- 1 teaspoon Italian seasoning
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon onion powder
Optional Add-ins:
- Cooking spray (avocado or olive oil)
- Fresh parsley for garnish
- Lemon wedges for serving
Step-by-Step Instructions
Step 1: Prepare the Zucchini
Wash your zucchinis thoroughly and pat them completely dry with paper towels. This step is crucial because excess moisture is the enemy of crispiness. Trim off both ends, then slice the zucchinis into rounds about 1/4-inch thick. Try to keep them uniform in size so they cook evenly. If your zucchinis are extra watery, lay the slices on paper towels and sprinkle lightly with salt. Let them sit for 10 minutes, then pat dry again.
Step 2: Set Up Your Breading Station
Grab three shallow bowls for your breading station. In the first bowl, whisk together the egg and heavy cream until well combined. In the second bowl, mix the almond flour with half of the parmesan cheese. In the third bowl, combine the remaining parmesan with all the spices: garlic powder, Italian seasoning, smoked paprika, salt, pepper, and onion powder. Mix each bowl thoroughly so the seasonings are evenly distributed.
Step 3: Coat the Zucchini Slices
Now for the fun part! Take each zucchini round and dip it first into the almond flour mixture, coating both sides and shaking off excess. Next, dip it into the egg mixture, letting any excess drip off. Finally, press it into the parmesan-spice mixture, making sure both sides are well coated. Place the coated slices on a plate and continue until all zucchini is breaded. Don’t stack them or they’ll stick together.
Step 4: Preheat the Air Fryer
Preheat your air fryer to 400°F for about 3 minutes. This ensures the zucchini starts cooking immediately and develops that crispy exterior. While it’s preheating, lightly spray your air fryer basket with cooking spray to prevent sticking.
Step 5: Arrange in the Air Fryer
Place the breaded zucchini rounds in a single layer in your air fryer basket. Don’t overlap them or crowd the basket—air needs to circulate around each piece for maximum crispiness. Depending on your air fryer size, you’ll likely need to cook these in 2-3 batches. Lightly spray the tops of the zucchini with cooking spray for extra crispiness.
Step 6: Air Fry to Perfection
Cook at 400°F for 10-12 minutes, flipping the zucchini rounds halfway through at the 6-minute mark. They’re done when they’re golden brown and crispy on both sides. The cheese should be melted and slightly caramelized. If some pieces cook faster than others, remove them and let the rest continue cooking for another minute or two.
Step 7: Serve Immediately
Transfer the crispy zucchini to a serving platter right away. Garnish with fresh chopped parsley and serve with your favorite keto-friendly dipping sauce. These are best enjoyed hot and fresh from the air fryer when they’re at peak crispiness.
What to Serve Air Fryer Zucchini Keto With
These crispy zucchini rounds are incredibly versatile! Serve them as an appetizer with ranch dressing, garlic aioli, or sugar-free marinara sauce for dipping. They make an excellent side dish alongside grilled chicken, steak, or salmon.
For a complete keto meal, pair them with cauliflower mac and cheese or a fresh Caesar salad. They’re also perfect for game day spreads—arrange them on a platter with other keto appetizers buffalo chicken dips.
My favorite way to enjoy them is with a creamy avocado-lime dipping sauce that adds richness and tang. You could also serve them with a side of sour cream mixed with fresh herbs.
Top Tips for Perfecting Air Fryer Zucchini Keto
Master the Moisture Management
The biggest secret to crispy zucchini is removing as much water as possible before cooking. After slicing, lay them on paper towels, sprinkle with salt, and let them sit for 10 minutes. The salt draws out moisture. Pat them bone-dry before breading. This extra step makes all the difference between soggy and crispy.
Don’t Skip the Preheat
Always preheat your air fryer. Starting with a hot basket ensures the coating sets immediately and becomes crispy rather than absorbing into the zucchini. Those 3 minutes of preheating are worth every second.
Size Matters
Keep your slices uniform at about 1/4-inch thick. Thicker slices won’t cook through properly, and thinner ones will burn before the inside is tender. Use a ruler if you need to until you get the hang of it.
Work in Batches
I know it’s tempting to crowd everything in at once, but resist! Overlapping pieces will steam instead of crisp. Give each piece breathing room. Yes, it takes longer, but the results are worth it.
Ingredient Substitutions
No almond flour? Use coconut flour, but reduce the amount to 1/3 cup as it’s more absorbent. Can’t do dairy? Nutritional yeast works instead of parmesan—use 3/4 cup for similar coverage. For egg-free, try a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit 5 minutes).
Temperature Troubleshooting
If your zucchini is browning too quickly but isn’t crispy, lower the temperature to 375°F and cook a few minutes longer. Every air fryer runs differently, so adjust as needed. Mine runs hot, so I usually do 390°F for perfect results.
Common Timing Mistakes
Don’t flip too early—wait until at least 6 minutes so the coating has time to set. Flipping too soon can cause the breading to fall off. Also, if they’re not crispy enough at 12 minutes, give them another 2-3 minutes rather than cranking up the heat.
Storing and Reheating Tips
Refrigerator Storage
Store leftover air fryer zucchini in an airtight container in the refrigerator for up to 3 days. To maintain some crispiness, place a paper towel in the container to absorb moisture. Let them cool completely before storing to prevent condensation.
Reheating for Best Results
The air fryer is hands-down the best reheating method. Preheat to 350°F and reheat for 3-4 minutes until warmed through and crispy again. Don’t use the microwave—it’ll make them soggy. An oven works too: 375°F for 5-7 minutes on a baking sheet.
Freezing Instructions
These can be frozen, though they’re best fresh. To freeze, place cooked and cooled zucchini in a single layer on a baking sheet and freeze until solid (about 2 hours). Transfer to a freezer bag with parchment paper between layers. Store for up to 2 months.
To cook from frozen, add 3-4 minutes to the cooking time and don’t thaw first. Air fry at 380°F for 15-16 minutes, flipping halfway through.
Pro Tip for Meal Prep
You can prep the breaded zucchini ahead of time. Coat them and arrange on a parchment-lined baking sheet. Freeze until solid, then transfer to a freezer bag. Cook from frozen whenever you want a quick snack—no thawing needed.
Tips for Avoiding Common Mistakes
Mistake #1: Using Wet Zucchini
This is the number one culprit behind soggy results. Always dry your zucchini thoroughly. Even if it looks dry, give it another pat. Excess moisture creates steam, which is the opposite of what we want.
Mistake #2: Old Almond Flour
Almond flour can go rancid quickly. Check the expiration date and give it a smell—it should smell nutty, not bitter or sour. Fresh almond flour creates a better coating and tastes significantly better.
Mistake #3: Pressing the Coating Too Hard
When coating your zucchini, press gently but don’t mash. Pressing too hard compresses the zucchini and releases more water. A gentle press is all you need for the coating to adhere.
Mistake #4: Not Adjusting for Your Air Fryer
All air fryers cook differently. The first time you make this, check at the 8-minute mark. If they’re already golden, they’re done. If barely colored, they need more time. Take notes for next time.
Mistake #5: Skipping the Oil Spray
A light mist of oil spray helps achieve that golden, crispy exterior. Don’t drench them, just a quick spritz on top before cooking makes a noticeable difference.
Mistake #6: Using Pre-Shredded Cheese
Pre-shredded parmesan contains anti-caking agents that prevent proper crisping. Always grate your own from a block for the best texture and flavor.
Frequently Asked Questions
How do I keep my air fryer zucchini from getting soggy?
The key is removing moisture before cooking. Salt your sliced zucchini and let it sit for 10 minutes, then pat completely dry. Also ensure you don’t overcrowd the air fryer basket—air circulation is essential for crispiness. Finally, serve immediately for best results.
What’s the best dipping sauce for keto zucchini?
Ranch dressing is classic, but I love garlic aioli, sugar-free marinara, or a spicy sriracha mayo. For something different, try tzatziki sauce or a creamy avocado-cilantro dip. Any keto-friendly sauce works beautifully with these.
Can I use yellow squash instead of zucchini?
Yes! Yellow squash works perfectly with the same cooking time and method. You can even mix both for a colorful presentation. The texture and moisture content are similar, so no adjustments needed.
How many carbs are in air fryer zucchini keto?
Each serving (about 6-8 pieces) contains approximately 4-5 net carbs. The zucchini itself is very low carb, and using almond flour instead of regular breadcrumbs keeps it keto-friendly. The parmesan cheese adds minimal carbs.
Why isn’t my coating sticking to the zucchini?
Make sure your zucchini is completely dry before starting. The egg wash acts as glue, so ensure you’re coating thoroughly. Press the final coating gently but firmly. If it’s still not sticking, add a tablespoon of mayonnaise to your egg mixture for better adhesion.
Can I make these in a regular oven?
Yes! Preheat your oven to 425°F and place zucchini on a parchment-lined baking sheet. Spray with oil and bake for 20-25 minutes, flipping halfway through. They won’t be quite as crispy as air-fried, but still delicious.
How do I know when they’re done cooking?
Look for golden brown color on both sides and edges that look crispy. The cheese should be melted and slightly bubbling. If you’re unsure, take one out and test it—it should have a satisfying crunch when you bite into it.
