In a bowl, whisk together the eggs, heavy cream, salt, pepper, garlic powder, and onion powder. Stir in shredded cheese, bacon, and bell peppers.
Roll out the pie crust and press it into a small air fryer-safe baking dish. Pour the egg mixture into the crust, spreading evenly.
Preheat the air fryer to 320°F (160°C). Place the quiche in the air fryer basket and cook for 12-15 minutes, or until the center is set and the top is golden.
Let the quiche cool for a few minutes before slicing. Serve warm and enjoy!
