Ingredients

You probably have everything you need already. This recipe keeps it simple so the zucchini flavor really shines through.

2 medium zucchini (about 1 pound total)
1 tablespoon olive oil
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper
Optional: ¼ teaspoon smoked paprika or Italian seasoning

How to Make Air Fryer Zucchini (Sliced)

This couldn’t be simpler — slice, season, air fry, and you’re done.

Slice the zucchini. Cut each zucchini into rounds about ¼-inch thick — try to keep them even so they cook at the same rate.
Pat dry. Use paper towels to blot excess moisture from the slices — this helps them crisp up instead of steaming.
Season the zucchini. Toss the slices in a bowl with olive oil, garlic powder, salt, and pepper until evenly coated.
Preheat the air fryer. Set your air fryer to 400°F (200°C) and let it preheat for 3 minutes.
Arrange in a single layer. Place zucchini slices in the air fryer basket in one layer with a little space between each piece — don’t overlap or they’ll steam instead of crisp.
Air fry. Cook at 400°F (200°C) for 10 minutes, shaking the basket halfway through to ensure even browning.
Check for doneness. Zucchini should be tender with golden edges — if you want them crispier, add 2 more minutes.
Serve immediately. Transfer to a serving plate and garnish with parmesan, lemon zest, or fresh herbs if desired.

💡 Air Fryer Pro Tip

Don’t skip the patting-dry step. Zucchini holds a lot of moisture, and if you toss it straight into the air fryer wet, you’ll end up with limp, soggy slices instead of crispy ones. A quick blot with paper towels makes all the difference.

Recipe Variations

◆ Parmesan-Crusted Zucchini

After tossing the zucchini with oil and seasoning, sprinkle 2 tablespoons of grated parmesan over the slices before air frying. The cheese forms a crispy, savory crust that’s absolutely addictive. This version pairs beautifully with marinara for dipping.

◆ Lemon Herb Zucchini

Add 1 teaspoon of Italian seasoning and the zest of half a lemon to the oil mixture. After air frying, squeeze fresh lemon juice over the hot zucchini and toss with chopped fresh basil or parsley. It’s bright, fresh, and perfect for summer meals.

◆ Spicy Cajun Zucchini

Replace the garlic powder with 1 teaspoon of Cajun seasoning and add a pinch of cayenne if you like extra heat. The smoky, spicy flavor makes these zucchini slices perfect alongside grilled chicken or air fryer pork chops.

What to Serve With Air Fryer Zucchini (Sliced)

These zucchini slices are the ultimate flexible side dish. Here’s what works beautifully:

Grilled or air fried proteins. Pair them with air fryer chicken breast, air fryer salmon, or steak for a complete low-carb meal.

Pasta dishes. Serve alongside spaghetti, lasagna, or any Italian meal — the light, crispy zucchini balances richer sauces perfectly.

Grain bowls. Toss them into quinoa or rice bowls with hummus, feta, and cherry tomatoes for a Mediterranean-inspired lunch.

As a snack. Honestly, these are so good you can just eat them straight from the air fryer with a little ranch or garlic aioli for dipping.

Storage & Reheating

Fridge: Store leftover air fryer zucchini in an airtight container in the refrigerator for up to 3 days. They’ll lose some crispness, but they’re still tasty cold in salads or reheated.

Freezer: Freezing isn’t recommended — zucchini has high water content and becomes mushy when thawed.

Reheating: Place zucchini slices back in the air fryer at 375°F (190°C) for 3 to 4 minutes to crisp them up again. Don’t microwave — you’ll end up with soggy vegetables.

Frequently Asked Questions

Do I need to peel the zucchini before air frying?

Nope. The skin is totally edible and adds extra nutrients and texture. Just give the zucchini a good wash before slicing. If you’re using larger, older zucchini with tougher skin, you can peel them, but it’s not necessary for medium-sized ones.

Can I make air fryer zucchini (sliced) without oil?

You can, but the results won’t be as crispy or flavorful. A light coating of oil helps the seasoning stick and promotes browning. If you’re avoiding oil, try using a spray bottle with a tiny amount of olive oil or a non-stick cooking spray.

How do I prevent the zucchini from getting soggy?

Pat the slices dry with paper towels before seasoning, don’t overcrowd the basket, and make sure your air fryer is preheated. Moisture is the enemy of crispiness, so removing as much water as possible is key.

Can I use yellow squash instead of zucchini?

Absolutely. Yellow squash works exactly the same way — same cooking time, same temperature. You can even mix both for a colorful side dish.

How thick should I slice the zucchini?

Aim for about ¼-inch thick. Thinner slices will crisp up faster but can burn easily, while thicker slices take longer and may not get as crispy on the edges. Consistency is more important than exact thickness — just try to keep them all the same size.
