Start by preheating the oven to 225 degrees Celsius (437 degrees Fahrenheit) (fan).

Roll out the dough on a baking sheet and let it sit at room temperature for a bit.

Spread ricotta on the base.

Cut onions and potatoes into thin slices and place them on the pizza base.

Season with salt and pepper.

Mix pesto and oil in a small ramekin/bowl and spread it on the pizza - sprinkle with grated mozzarella at the end.

When the oven is hot, switch it from fan to conventional oven.

Bake the pizza in the oven at 225 degrees Celsius (437 degrees Fahrenheit) for approximately 12-15 minutes.
