Preheat your air fryer for 3 minutes to 350F (175C).
Prep the crust: Roll out the thawed pie crust into your 9-inch pie plate and using your fingers, press the edges firmly into the bottom and edges of the pie plate. I used a round 9-inch aluminum foil pan. (Picture 1). You can use any oven-safe pie plate that fits in your air fryer. The appliance that I use is Cuisinart Air Fryer Oven. Press lightly to fit, and fill in any gaps or cracks using your fingers.
Once the crust is situated, put it in the air fryer and cook for 5 minutes at 350F.
While the crust is goldening, mix together a filling of eggs, shredded cheese, and cooked chopped bacon for an ooey-gooey center that will make you say mmmm. Lightly whisk all the ingredients for a minute.
Remove the crust from the air fryer. It should look slightly golden with some bubbly brownish spots.
Raise the temperature to 400F (200C)
Pour the egg mixture into your slightly cooked crust.
Cover the entire pan with aluminum foil, ensuring the edges are secured and will not be lifted by a powerful air fryer fan.
Cook on air fry mode (air crisp) until the center is set and no longer wobbly; 20-25 minutes.
Finally, top off with more cheese if desired, and send back to the air fryer uncovered for just a minute or two until the quiche has golden brown edges and the cheese is melted on top. (Pictures 2 and 3).
Let cool for a few minutes before slicing and serving.
