Core and slice the apples into evenly thick wedges, about 1/4 inch thick, to ensure uniform cooking.
Place the apple slices in a mixing bowl, then sprinkle smoked paprika and sea salt evenly over them.
Toss the apple slices gently to coat them thoroughly with the spices, making sure each piece has a light smoky crust.
Preheat the air fryer to 350°F (175°C). Once hot, arrange the apple slices in a single layer in the air fryer basket, ensuring they are not overlapping.
Air fry the apples for about 12-15 minutes, flipping halfway through, until they develop crispy edges and are tender inside, with just a slight aroma of smoked paprika.
Remove the apples from the air fryer once they are evenly golden-brown and crispy on the edges, and let them cool slightly for a few minutes.
Serve the smoked paprika air-fried apples as a snack or dessert, enjoying their crunchy exterior and juicy interior with smoky hints and a touch of sea salt.
