Bring a small pot of water to a boil and season with ½ teaspoon salt and ½ teaspoon garlic powder. Cook chopped carrots and broccoli for one minute, then drain.
Form the pie crust into a tin pie pan and crimp the edges. Brush with 1 teaspoon softened butter, then air fry at 325°F for 5 minutes.
Layer Swiss cheese slices along the bottom of the pie crust, then distribute the broccoli, carrots, diced ham, and cheese evenly over the surface.
Prepare Egg Custard
Whisk eggs in a medium mixing bowl, then add heavy cream and spices and whisk to incorporate.
With the pie plate in the air fryer, carefully pour the egg custard over the quiche fillings.
Air Fryer Cooking Instructions
Air fry quiche at 375°F for 20 minutes, then loosely cover with foil (without touching the quiche filling) and air fry for another 20 minutes. Reduce the temperature to 350°F and air fry for an additional 20 minutes or until the center is no longer jiggly and a knife inserted in the center comes out clean. Cool for 5 minutes, then serve.
Notes
If adding chives, be aware that they may float to the surface and be concentrated in the center of the quiche. For this reason, I'm leaving them as an optional ingredient.
You may not need to use all the custard; don't overfill the pan. If you don't want to waste it, just scramble the rest in a pan.
Be careful when adding the foil over the quiche. First, you don't want it to touch the surface of the quiche and mar the appearance. Secondly, you don't want the foil to touch the heating element in the lid, which could spark a fire.
Store leftovers in an airtight container in the fridge for up to 4 days, or freeze wrapped in aluminum foil, inside a freezer bag for up to 3 months.
