How to prepare Vegan Potato Gateau

To prepare the vegan potato gateau, start by washing the potatoes well. Then, without peeling them, place them in a pot with plenty of cold salted water 1. Bring to a boil and let them cook for 35 60 minutes. Meanwhile, take care of the filling. First, blanch the peas for a few minutes. Then take the mushrooms, remove the dirty part with a knife 2, and slice them 3.

Take the leek, remove the outer leaves and slice it thinly 4. Roughly chop the sun-dried tomatoes with a knife 5. In a pan heat the extra virgin olive oil and add the thinly sliced leek 6.

Add the sun-dried tomatoes 7 and the sliced mushrooms 8. Finally add the blanched peas 9 and cook for 5 10 minutes.

Season with salt and pepper 10; add the marjoram and turn off the heat. At this point the potatoes should be cooked. Test by piercing them with a fork 11. Drain them, let them cool slightly, then mash them while still hot with a potato ricer or masher 12, collecting the pur e9e in a bowl.

Stir into the mashed potatoes the nutritional yeast 13, the oat milk 14 and the extra virgin olive oil 15

Also add the nutmeg 16, salt and pepper 17. Mix well with a spatula 18.

You should obtain a creamy, homogeneous mixture 20. Grease an 8 2/3-inch round pan and dust the bottom with breadcrumbs 20. Pour half of the potato mixture inside and press it with the back of a spoon so that the edges are slightly thicker 21, thus creating a well for the filling.

Add all the filling and spread it evenly 22, cut the cheese into pieces 23 and place it over the vegetables 34.

Cover with the remaining potato mixture 25, gently level the surface 26, finish with a sprinkling of breadcrumbs 27.

Add a drizzle of extra virgin olive oil. Bake in a preheated conventional oven at 356 b0F for 35 40 minutes, until the surface is well browned. Once cooked, let the gateau rest for 10 15 minutes before slicing: this step is essential to obtain compact slices. The vegan gateau is ready to serve 30.

Storage

You can store the vegan potato gateau in the refrigerator for 2 3 days, well wrapped with cling film or inside an airtight container.

Before serving it again, we recommend reheating it in the oven at 320 b0F for about 10 15 minutes or in the microwave for a few minutes, so the filling becomes soft and slightly melty again.

You can also freeze it already portioned: this way you only need to thaw the slices in the refrigerator and reheat them in the oven for a few minutes.

Tip

For an even tastier oven-baked vegan potato gateau, you can add a tablespoon of mild mustard or a pinch of turmeric to the potato mixture, which will also give a more intense color.

If you want an even crispier surface, mix the breadcrumbs with a tablespoon of flaked nutritional yeast or with chopped aromatic herbs, such as thyme or rosemary.

For a variation closer to the traditional gatt f2 napoletano, you can enrich the filling with cubes of smoked vegan cheese, which will recall the flavor of provola.
