What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a crispy texture—no fancy extras, just the good stuff. Most of these are pantry staples, and you can easily swap ingredients based on what you have on hand or dietary needs.

• Zucchini (2 medium, about 450g), sliced into 1/4-inch (0.6 cm) rounds: Fresh, firm zucchini works best. No need to peel—just trim the ends and slice.
• Egg (1 large): Acts as the binder for the breadcrumb coating. If you’re vegan, use a flax egg (1 tbsp flaxseed meal + 2.5 tbsp water, mixed and set for 5 minutes).
• Panko breadcrumbs (1/2 cup / 30g): I prefer panko for extra crunch, but regular or gluten-free breadcrumbs work too.
• Parmesan cheese (1/3 cup / 30g), finely grated: Freshly grated is best for flavor and texture, but pre-grated is totally fine for busy nights.
• Cornstarch (2 tbsp / 16g): Adds crispiness to the coating—don’t skip this! If you’re out, flour or arrowroot powder can be subbed.
• Garlic powder (1/2 tsp / 2g): Brings a subtle, savory kick. You can use onion powder as a swap (or add both for more depth).
• Dried Italian herbs (1/2 tsp / 1g): A classic flavor boost. If you love basil or oregano, add a bit extra.
• Salt (1/4 tsp / 1.5g) & black pepper (1/4 tsp / 1g): Season to taste. I like to finish with a pinch of flaky salt after air frying.
• Olive oil spray: Just a light mist before air frying helps everything turn golden and crispy. Avocado oil spray works too.
• Optional for serving: Warm marinara sauce for dipping, lemon wedges for brightness, or a sprinkle of fresh parsley.

Ingredient notes and swaps:

• If you’re gluten-free, use GF panko or crushed rice crackers.
• For a dairy-free version, swap parmesan for nutritional yeast or a plant-based parmesan.
• Don’t have Italian herbs? Mix dried basil, oregano, and thyme in equal parts.
• In summer, try thin slices of yellow squash or eggplant for a twist.

I’ve used several brands of parmesan and panko; honestly, the best results come from finely grated, fresh parmesan and Japanese panko, but do what works for your budget and pantry. The magic is in the air fryer, anyway!

Equipment Needed

• Air fryer (basket-style or oven-style): My trusty 5-quart air fryer fits about half a batch at once. If you have a smaller model, just work in batches—it’s worth it.
• Mixing bowls (2-3): One for the egg, one for the breadcrumb mixture, and one for dredging the zucchini.
• Measuring cups and spoons: For accuracy. I sometimes eyeball the herbs, but measuring keeps the flavor balanced.
• Tongs or a fork: Makes flipping the zucchini easy and keeps fingers clean.
• Baking rack or plate lined with paper towels: For cooling the cooked zucchini and keeping them crispy.
• Oil spray bottle: I like refillable bottles for olive oil—they save money and cut waste. Canned olive oil spray works fine, too.

If you don’t have an air fryer, you can use a convection oven with a wire rack—just increase the cooking time and check for crispness. I once tried this with a regular oven, and while it works, the air fryer really gives the best crunch. And here’s a tip: after using your air fryer, let it cool and wipe down the basket to keep it performing at its best (trust me, stuck-on cheese is a pain to scrub!).

How to Make Low-Calorie Air Fryer Zucchini Parmesan

1. Prep the zucchini:
   • Wash and dry 2 medium zucchinis (about 450g).
   • Trim the ends and slice into 1/4-inch (0.6 cm) thick rounds. Try to keep the slices even—this helps them cook uniformly.

   Pro tip: If your zucchini is very wet, pat slices dry with a paper towel for crispier results.

2. Set up your breading station:
   • In one shallow bowl, crack 1 large egg and beat lightly with a fork.
   • In a second bowl, combine 1/2 cup (30g) panko breadcrumbs, 1/3 cup (30g) grated parmesan, 2 tbsp (16g) cornstarch, 1/2 tsp garlic powder, 1/2 tsp dried Italian herbs, 1/4 tsp salt, and 1/4 tsp black pepper. Mix well.
3. Bread the zucchini:
   • Working in batches, dip each zucchini slice first into the beaten egg, letting any excess drip off.
   • Then, dredge in the breadcrumb mixture, pressing lightly to coat both sides.
   • Place the coated slices on a plate or tray. Repeat until all are coated.

   Note: If you run out of breading, just make a little more using the same ratio!

4. Preheat and load the air fryer:
   • Preheat your air fryer to 400°F (200°C) for 3 minutes (if your model requires preheating).
   • Arrange breaded zucchini in a single layer in the basket. Don’t crowd them—work in batches if needed.
   • Lightly spray the tops with olive oil spray (don’t oversaturate—just a mist).
5. Air fry the zucchini parmesan:
   • Air fry at 400°F (200°C) for 8–10 minutes, flipping halfway through.
   • Zucchini should be golden brown and crisp on the outside, tender inside.
   • If needed, air fry for an extra 1–2 minutes for extra crunch.

   Sensory cue: The coating should sizzle and smell delightfully cheesy as it cooks. If it starts to brown too quickly, lower the temp to 375°F (190°C).

6. Serve:
   • Transfer to a rack or paper towel-lined plate to cool for 2-3 minutes (this keeps them crisp).
   • Sprinkle with extra parmesan, herbs, or a pinch of flaky salt, if desired.
   • Serve hot with warm marinara sauce or your favorite dip.

Troubleshooting tips: If your breading isn’t sticking, pat zucchini dry and try double-dipping in egg and crumbs. For uneven browning, rotate the air fryer basket halfway through. And if you end up with leftovers (rare, but it happens!), see the storage section below for the best reheating method.

Cooking Tips & Techniques

• Don’t skip the oil spray: This is the secret to getting that deep-fried crunch without all the fat. Just a light mist is enough—too much, and things get soggy.
• Keep slices uniform: It sounds fussy, but even slices mean even cooking. I use the side of a chef’s knife as a mini ruler.
• Work in batches: If you pile the zucchini in, you’ll end up steaming them instead of frying. Be patient; crispy is always worth the wait.
• Flip for even crispness: Flipping halfway is key. I learned this the hard way the first time—one side was perfect, the other… not so much. Tongs make this super easy.
• Use parchment for easy cleanup: If your air fryer basket is prone to sticking, try a perforated parchment liner. Just make sure air can circulate.

Common mistake? Overcrowding. Trust me, I’ve done it. The slices end up limp and pale. Give them space, and they’ll reward you with maximum crunch. Another tip from my kitchen: don’t walk away for too long—air fryers cook fast, and a minute can be the difference between golden brown and “oops, burnt.”

If you’re multitasking (making salad or pasta on the side), set a timer for flipping. And if you want to prep ahead, you can bread the zucchini earlier in the day and keep them on a tray in the fridge. Just bring to room temp before air frying for best results. Consistency really is about those small, careful steps!

Variations & Adaptations

• Gluten-Free: Use gluten-free panko or crushed rice crackers in place of regular breadcrumbs for a crunchy, allergy-friendly option.
• Dairy-Free: Swap the parmesan for nutritional yeast or a dairy-free parmesan (there are some great vegan brands out there). The flavor stays savory and cheesy.
• Spicy Kick: Add a pinch of red pepper flakes or a dash of cayenne to the breadcrumb mix for a little heat. My husband loves this spicy twist paired with a cool ranch dip!
• Seasonal Veggies: Try this method with thinly sliced yellow squash, eggplant, or even sweet potato rounds. Just adjust the air frying time as needed—softer veggies may cook faster.
• Oven-Baked: No air fryer? Bake on a wire rack set over a baking sheet at 425°F (220°C) for 15-18 minutes, flipping halfway through. Not quite as crisp, but still delicious.
• Keto/Low-Carb: Swap panko for crushed pork rinds or almond flour. I’ve made this swap for friends on keto, and they raved about the crunch!

Personally, I’ve made a batch with half zucchini and half eggplant when I was low on zucchini—total hit! If allergens are a concern, double-check your breadcrumbs and cheese sources. You can get creative with seasonings too—smoked paprika, cumin, or even lemon zest can work wonders.

Serving & Storage Suggestions

This air fryer zucchini parmesan is at its absolute best served hot and crispy, straight from the fryer. I love to pile them onto a platter with a bowl of warm marinara or garlic aioli for dipping—total crowd-pleaser!

• Serving: Serve as a side with grilled chicken, pasta, or as a crunchy appetizer. Garnish with extra parmesan, chopped parsley, or a squeeze of lemon for a fresh finish.
• Pairings: Goes great with a simple garden salad, roasted veggies, or even as a topper for grain bowls.
• Storage: Store leftovers in an airtight container in the fridge for up to 3 days.
• Reheating: For best results, pop them back in the air fryer at 350°F (175°C) for 3-4 minutes until crisp. Microwaving tends to make them soggy, so I try to avoid that.
• Freezing: I don’t recommend freezing—they lose their crunch—but you can freeze breaded, uncooked slices, then air fry straight from frozen (just add 2-3 minutes to the cook time).

Honestly, these disappear fast at my house, but when I do have leftovers, they make a great addition to wraps or tossed into a salad. The flavors actually deepen a bit overnight, and the coating stays surprisingly crisp if you reheat in the air fryer.

Frequently Asked Questions

How do I make sure my air fryer zucchini parmesan gets really crispy?

For the crispiest results, slice the zucchini evenly, pat them dry, use panko breadcrumbs, and don’t overcrowd the air fryer basket. Flip halfway through and give a light mist of oil spray before cooking.

Can I use yellow squash instead of zucchini?

Absolutely! Yellow squash works just as well—just slice to the same thickness and follow the same instructions. You might need to shave a minute off the cooking time since it’s a bit softer.

What dipping sauces go best with this recipe?

Classic marinara is always a hit. You can also try ranch, garlic aioli, or even a spicy sriracha yogurt dip for something different. I love changing it up based on what’s in my fridge.

Is this recipe gluten-free?

It can be! Just swap out the regular panko for gluten-free breadcrumbs or crushed rice crackers. Make sure your parmesan is gluten-free too (most are, but it’s good to check).

Can I prep these ahead of time?

You can bread the zucchini slices ahead and store them in the fridge for a few hours before air frying. When you’re ready to cook, let them sit out for a few minutes so they’re not ice-cold, then air fry as usual for the best texture.
