Air Fryer Roasted Zucchini and Squash with Parmesan is my weeknight answer to “I need a vegetable side, fast.” You get tender slices with browned edges and a savory Parmesan finish, without turning on the oven.
Why This Air Fryer Recipe Works
Zucchini and yellow squash cook quickly, but they can go limp if they steam. The air fryer’s circulating heat drives off moisture faster than a sheet pan, so the edges brown while the centers stay tender.
Parmesan adds salty, nutty flavor and helps create a lightly crisp coating where it touches the hot basket. A small amount of oil keeps everything glossy and encourages even browning.
- Fast cook time for busy nights
- Easy seasoning that fits lots of menus
- Minimal cleanup compared to oven roasting
Ingredients You’ll Need
Stick with medium zucchini and squash for the best texture. Oversized ones tend to be wetter and softer once cooked.
- 2 medium zucchini
- 2 medium yellow squash
- 1 1/2 tbsp olive oil
- 1/2 tsp kosher salt (adjust to taste)
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
- 1/2 tsp Italian seasoning (or dried oregano)
- 1/3 cup finely grated Parmesan (not shredded)
- Optional: pinch of red pepper flakes, lemon wedge for serving
How to Make Air Fryer Roasted Zucchini and Squash with Parmesan in the Air Fryer
1) Preheat the air fryer to 400°F for 3 minutes (if your model benefits from preheating).
2) Slice the zucchini and squash into 1/2-inch thick rounds. Try to keep them uniform so they cook at the same pace.
3) In a large bowl, toss the slices with olive oil, salt, pepper, garlic powder, and Italian seasoning until evenly coated.
4) Add the Parmesan and toss again. You want a light, even dusting—some will fall off, and that’s fine.
5) Arrange the slices in the air fryer basket in a single layer. A little overlap is okay, but avoid piling them up or they’ll steam.
6) Air fry until browned at the edges and tender, shaking the basket halfway through.
7) Taste and finish with an extra pinch of salt, more Parmesan, or a squeeze of lemon if you want it brighter.
Air Fryer Time and Temperature
Cook at 400°F for 10–14 minutes total, shaking or flipping once at about the 6-minute mark.
Exact timing depends on slice thickness, how crowded the basket is, and your air fryer model. Start checking at 10 minutes; you’re looking for browned edges and a fork-tender center.
- Thinner slices (about 1/4 inch): 8–11 minutes
- Thicker slices (about 1/2 inch): 10–14 minutes
- If the Parmesan darkens too fast: drop to 375°F and add 2–3 minutes
Tips for the Best Results
Moisture is the main challenge with zucchini and squash. A few small tweaks make a big difference in browning.
- Cut evenly: consistent thickness prevents some pieces from turning soft while others overbrown.
- Don’t overcrowd: cook in two batches if needed for better color and texture.
- Use finely grated Parmesan: it clings better and browns more evenly than thicker shreds.
- Shake halfway: it redistributes the slices and keeps the cheese from sticking in one spot.
- Serve right away: these are best hot, when the edges are at their crispest.
Variations and Substitutions
This recipe is flexible, so it’s easy to match what you’re cooking.
- Cheese swap: try Pecorino Romano for a saltier bite, or grated Asiago for a milder finish.
- Add crunch: toss in 2–3 tbsp panko with the Parmesan for more crisp edges (spritz lightly with oil).
- Lemon-herb: skip Italian seasoning and use dried dill, then finish with lemon zest.
- Spicy: add 1/4 tsp smoked paprika and a pinch of cayenne.
- Lower salt: reduce added salt and rely on Parmesan, then season at the table.
What to Serve With It
Air Fryer Roasted Zucchini and Squash with Parmesan works as a side for just about any protein. It’s also an easy way to round out a pasta night.
- Chicken (grilled, roasted, or air fried) with a simple salad
- Steak or pork chops with a baked potato
- Salmon and rice, with lemon on the side
- Spaghetti or pesto pasta as a veggie side

Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. The vegetables will soften as they sit, which is normal.
To reheat, spread in a single layer and air fry at 350°F for 3–5 minutes, just until warmed and the edges perk back up. Microwaving works, but it makes the zucchini and squash much softer.
If you’re meal-prepping, consider undercooking by 1–2 minutes, then finishing during reheating.

FAQ
How do I keep zucchini and squash from getting soggy in the air fryer?
Don’t overcrowd the basket, and cook at a higher heat (400°F) to drive off moisture quickly. Also, keep slices around 1/2 inch so they don’t collapse before the edges brown.
Do I need to peel zucchini or yellow squash?
No. The skins are tender and help the slices hold their shape. Just wash well and trim the ends.
When should I add the Parmesan—before or after air frying?
Adding it before cooking gives you browned, savory bits on the surface. If you prefer a fresher cheese flavor, add half before and sprinkle the rest right after cooking.
Why is my Parmesan burning?
Some air fryers run hot, and finer cheese can brown quickly. Try lowering to 375°F, using a slightly thicker slice, or mixing the Parmesan with a little panko to buffer direct heat.
Can I use frozen zucchini or squash?
Fresh works best for roasting. Frozen releases more water and tends to steam; if you use it, expect a softer texture and cook in small batches at 400°F to help evaporate moisture.
