Add the olive oil, salt, pepper, and garlic powder to toss very well.
Add the veggies to the air fryer. Avoid overcrowding them and place them in the air fryer in a single layer. Depending on the size of your air fryer you may have to cook the veggies in 2 batches to avoid overcrowding.
Set your air fryer to 350 degrees Fahrenheit (175 degrees Celsius) and add the veggies in a single layer.
Air fry for 8 minutes. Toss the veggies once after 8 minutes of air frying and air fry for an additional 3-4 minutes.
Serve immediately.

Notes
When using multiple kinds of veggies in the same dish, we recommend chopping them strategically so they cook evenly. This means for harder vegetables (like carrots), we slice them more thinly. For softer vegetables (like bell peppers), we chop them in larger pieces. This way the vegetables become tender all at the same time and you avoid over-cooking some while under-cooking others.
How to roast frozen vegetables:Add about 5-6 minutes of additional cooking time.
How to reheat Air Fryer Roasted Vegetables:To reheat, simply add the veggies to the air fryer and air fry for about 3-4 minutes.
