Slow-roast the garlic

• Halve the garlic heads and set them cut side up in a small oven dish or frying pan.
• Drizzle generously with olive oil, season with salt and cover tightly with foil.
• Roast until the cloves are completely soft and golden.

Make the garlic oil

• Squeeze the soft roasted cloves out of their skins into a bowl.
• Mash them with a fork together with the roasting oil, chilli flakes and oregano.

Heat the oven

• Place a baking tray in the oven and preheat to its highest setting.

Shape the base

• Stretch the dough on a floured surface into a round, keeping a slightly thicker rim.
• Transfer it to baking paper and brush the surface with the garlic mixture.

Bake the pizza

• Slide the pizza onto the hot tray and bake until the crust is puffed and golden.
• Scatter the grated Parmigiano over the hot pizza and finish with a drizzle of olive oil and extra oregano.
