Remove the refrigerated pie crust from the fridge about 15 minutes before starting.
Unroll the dough, set your tart pan on top, and cut a circle about 1 inch wider than the pan.
Press the dough into the tart pan, tucking the edges and trimming excess so the crust is even with the rim.
Place the tart pan in the air fryer basket and cook at 300°F for 5 minutes.
Sprinkle the cheese into the bottom of the crust, then scatter the artichoke hearts and sun-dried tomatoes over the cheese.
Whisk together the egg and heavy cream until smooth, beating in a little extra air.
Carefully pour the egg mixture over the fillings until it just reaches the top edge of the crust. Do not overfill.
Return the quiche to the air fryer and cook at 300°F for about 10 minutes, until the center is set.
Let cool 1–2 minutes, then pop the quiche from the tart pan. Use a spatula to lift it off the base and serve.
