Calzone
A sealed, folded pizza — filling has to be low-moisture or the seam bursts in the oven.
What's going on here
A calzone is completely sealed, unlike an open pizza, which means any liquid the filling releases during baking has nowhere to escape except by building pressure until it finds — or blows through — the weakest point in the seam. Wet mozzarella, watery vegetables, and thin sauce all reliably cause this, which is why the filling here uses ricotta as its base (already fairly dry and holding together well) rather than a loose, sauce-heavy mixture, and why any vegetables are cooked down first to drive off their moisture the same way any pie or turnover filling in this cookbook is pre-cooked before being sealed inside pastry. Crimping the edge firmly, the same technique as a hand pie, and cutting a few small vents in the top gives any remaining steam a controlled way out rather than forcing the dough to find its own exit point under pressure.
Ingredients
Dough
- 3 cupsBread flour
- 1 cupWater, warm
- 1 1/8 tspInstant yeast
Instant/quick-rise: stir straight into the dry ingredients, no proofing needed.
- 2 tbspOlive oil
- 1 1/2 tspSalt
Filling
- 1 1/2 cupsRicotta
- 1 1/2 cupsMozzarella, shredded
- 1/2 cupParmesan, grated
- 1 1/2 cupsCooked, well-drained fillings
e.g. cooked sausage, sautéed mushrooms — nothing raw or wet
Finish
- 1Egg, beaten
Instructions
Dough
- Whisk the flour and yeast together, then stir in the water and oil to form a shaggy dough. Add the salt and knead until smooth.
Rise
- Cover and let rise until doubled.
Filling
- Mix the ricotta, mozzarella, Parmesan, and any additional cooked fillings together.
Tip: Anything wet — raw vegetables, watery sauce — needs to be cooked down and well drained first, or it releases liquid inside the sealed dough with nowhere to go.
Prep
- Heat the oven to 220°C (425°F).
Shape
- Divide the dough into 4 pieces and roll each into a thin round. Spoon filling onto one half of each round, leaving a border, and fold the other half over. Crimp the edge firmly, the same as a hand pie.
Bake
- Cut a couple of small vents in the top of each, brush with egg wash, and bake until deeply golden.
Tip: The vents give built-up steam a controlled way out — without them, it finds its own way, usually by bursting the seam.

Tips for this recipe
Calzone burst open in the oven
The filling was likely too wet, or the seal wasn't firm enough. Drain and dry any cooked fillings thoroughly, and press the crimped edge firmly closed all the way around.
Serve with sauce on the side
Rather than inside, which adds even more moisture to seal in — a bowl of warm marinara for dipping keeps the filling itself drier and the pastry crisper.
