Chop the mushrooms leaving the smaller ones whole. Set a skillet on medium heat and melt the butter. Add the chopped mushrooms and sauté for 6-7 minutes, until the water they release will evaporate. Remove from the heat and stir in a sprinkle of salt.
Stretch pizza dough to desired thickness, spread tomato sauce on top keeping about 1 cm away from the edges. Place mushroom all over the pizza, distributing them evenly. Top with diced mozzarella.
Bake in the pre-heated oven at 250°C (480°F) for 8-10 minutes or until the sides and cheese have nicely browned. As the pizza bakes, lightly whip the goat cheese with a small whisk. Transfer to a piping bag fitted with a star nozzle. Pipe goat cheese onto pizza as soon as it comes out of the oven.
Notes
If you want to make everything from scratch, you can use my easy pizza dough recipe and my favourite pizza sauce. If using frozen mushrooms budget in about 250 g (9 oz) mixed mushrooms and thaw on paper towel before use.Please notice that the nutritional information provided in this recipe card is calculated by an online tool and only meant to be used as a guideline.
