Microwave harder veggies for about 5 minutes to soften a bit. (I would do this for carrots, green beans, celeriac, parsnips, potatoes, turnips, kohlrabi, radishes, broccoli stems, etc.) Not zucchini which will get too soft.
Toss veggies with olive oil, spices and parmesan cheese.
Bake for 18-20 minutes or until the veggies start to brown and are cooked through.
Spray the basket of the air fryer with nonstick cooking spray. Add the seasoned veggie fries to the air fryer basket.
Set the temperature to 400°F and set the timer for 15 minutes. When the timer goes off add the zucchini if using and mix around.
Continue to cook for 10 more minutes until the fries are golden brown and fork tender.
