1. Preheat your air fryer to 360°F (182°C). This cooking temperature is optimal for ensuring the potatoes cook through while still achieving a crispy top layer.

2. Grease your baking dish with butter. This step is crucial for preventing sticking and adds an extra layer of flavor.

3. Layer the first batch of potato slices at the bottom of the dish. Aim for an even, slightly overlapping arrangement for uniform cooking.

4. Season this layer with a sprinkle of salt, pepper, and thyme. Even distribution is key here for flavor in every bite.

5. Add a layer of cheese mixture over the potatoes, followed by a generous pouring of the cream mixture. This combination is what gives the dish its creamy texture and rich taste.

6. Repeat the layering process until all ingredients are used, finishing with a layer of cheese on top.

7. Cover with foil if your air fryer tends to brown the top too quickly. This will allow the potatoes to cook without burning.

 

8. Cook in the air fryer for about 25 minutes. Then, if covered with foil, remove the foil and continue cooking for another 10 minutes to crisp the top. Keep an eye on it to prevent over-browning.

9. Check doneness by inserting a fork into the potatoes. They should be tender and the top golden brown.

10. Let it rest for 5 minutes before serving. This allows the layers to set and makes it easier to serve.
