Step 1: You will need:
— pizza dough
— pizza sauce
— mozzarella
— fresh crimini mushrooms
— ham
— dried oregano
— salt
— extra virgin olive oil

Step 2: The first thing you need to do is turn on your oven and preheat it to 220˚C/ 430˚F. While waiting for the oven to heat, prepare your ingredients. Start with the mozzarella: grate it on a coarse grater.

Step 3: Chop the mushrooms into thin round slices.

Step 4: Thinly slice the ham.

Step 5: Now let’s roll out the dough. You may stretch the crust with your knuckles like all professionals do, but it’s always easier to use a rolling pin. Sprinkle the table with flour, dip the dough in the flour as well and roll it into a thin sheet.

Step 6: Put the crust on an oiled pizza screen. Don’t worry if the crust loses its shape while you handle it — just shape it into a circle again and don’t worry about the small folds that you might get.

Tip: If you don’t have a pizza screen, you may use a baking sheet turned upside down (so that you can easily take your pizza off the sheet). And if you are lucky enough to own a pizza stone, don’t forget to preheat it for about 20 minutes before putting your calzone on it.

Step 7: Now let’s spread the sauce on one half of the crust — the one we’re going to put the toppings on. Put some sauce in the center, and then spread it out to the sides using the back of a spoon. Leave the edges without sauce.

Step 8: Lay the slices of ham on the sauce.

Step 9: Sprinkle with some grated mozzarella.

Step 10: Add the mushrooms.

Step 11: Cover the toppings with the other half of the crust. Press the edges of both halves together and then seal the calzone, folding the edge over and pinching down.

Step 12: We need to oil the calzone a bit so that it turns golden. Pour some olive oil on top of the calzone and spread it with your fingers. Season with dried oregano.

Tip: You may also make two or three small cuts in the dough to let the steam out.

Step 13: It’s time to put our calzone in the oven! Keep it in the oven for about 15-20 minutes — it can take more or less than that depending on how quickly your oven bakes.

Tip: Rotate the pizza screen a couple of times while baking to make sure that the calzone cooks evenly.

Step 14: A pizza screen won’t let your calzone get a well-cooked crispy bottom. To achieve a nice crispy calzone, take it off the screen a few minutes before it has finished baking and put it on a baking sheet. Bake the calzone on the sheet for 3-5 minutes more until its edges turn golden.

Step 15: The calzone is done! Cut it in half and serve.
