I couldn’t wait to share my version of the Potato Gateau and finally I managed to add the recipe with air fryer. Perfect as a main dish, second course or hearty side dish, this gateau is creamy inside and crispy outside… without guilt!
The Potato Gateau is a dish from our Italian tradition, and there are many versions, but the most well-known and representative is certainly the Neapolitan tradition. What I propose is the version my mom always made and still makes, where I made only a small change (besides the air fryer cooking) by adding a bit of milk, making the potato gateau even creamier inside.
Potatoes are very versatile, I adore them, and they lend themselves to many preparations ranging from first courses to side dishes to accompany our second courses.
Now let’s see how to prepare the Potato Gateau in air fryer, but I will also leave you, at the end of the recipe, the times and temperatures if you choose to bake it in the oven.

Steps
How to prepare Potato Gateau in Air Fryer
Cooking potatoes in a pot: Wash, peel, and cut the potatoes into chunks. Boil them until they are soft. You can also boil them whole with the skin and mash them with a potato masher without peeling. Use the method most convenient for you.
Cooking potatoes in a multicooker: Wash, peel, and cut the potatoes into chunks. Place them in the combi dish with 1 liter of water.
Set the switch to combi cooker mode and start the steam program for 10 minutes.
Once ready, drain them and transfer them into a bowl.
Mash them while still hot with the help of a fork to obtain a homogeneous puree. Set aside to cool for a few minutes.
Meanwhile, focus on filling the dough: cut the cooked ham first into strips, then into cubes.
Do the same with the cheese.
Add them to the potato puree, and add the egg, salt, pepper, a grating of nutmeg, and the milk.
Mix the mixture well.
Grease or butter a baking dish suitable for the air fryer (my Pyrex dish) and cover it with breadcrumbs. Pour the mixture of your gateau.
Level it well with a spoon and score the surface with the tines of a fork.
Sprinkle the surface with breadcrumbs and a drizzle of oil.
Place the dish in the air fryer and cook at 356°F for 18 minutes.
For extra crust, increase to 392°F for 3 minutes. Or, if you have the grill program, activate it for 2 minutes.
Remove the gateau from the fryer and let it cool a bit.
Irresistible with the crust on the surface and its internal creaminess 😍
Serve your Potato Gateau after letting it rest for a few minutes to set. Even better as the hours pass, when all the flavors blend more.

Variations and Tips
Replace the caciotta or cheese with mozzarella, remember to drain it well from its whey
You can add a tablespoon of breadcrumbs for a firmer mixture
For a vegetarian version, replace the cooked ham with sautéed vegetables
If you are lactose intolerant, you can omit the milk, although I recommend it for a creamier mixture, or use lactose-free milk. The same goes for cheeses, and use a well-aged Grana Padano or Parmesan, preferably 30 months
You can prepare it in several stages by boiling the potatoes in the morning and assembling and baking it later
About the baking dish…for this recipe, I used a Pyrex dish; you can use a non-stick dish of a size that fits your air fryer. I advise against silicone molds as they are not good heat conductors and would keep the base very moist; prefer aluminum and non-stick dishes, especially if you have a single-resistance air fryer
Storage of Potato Gateau
The Potato Gateau keeps in its dish in the refrigerator for a couple of days, well covered with cling film, and heat it in the air fryer or oven for a few minutes before serving
