✔ Updated · shape, cheese + sauce compared
Calzones and strombolis are both pizza dough baked around cheese and fillings. The difference is how the dough is shaped, what cheese goes inside and where the sauce ends up.
A calzone is a round of pizza dough folded into a half-moon over the filling and crimped shut, usually with ricotta and mozzarella inside and marinara served on the side for dipping. A stromboli is a rectangle of dough topped with mozzarella and cured meats, rolled into a log like a jelly roll, baked, and sliced into spiral pieces to share. Calzones come from Naples; stromboli was created in the Philadelphia area in the 1950s.
- Shape: calzones are folded half-moons; strombolis are rolled logs cut into slices.
- Cheese: calzones usually include ricotta; strombolis use mozzarella and often provolone, no ricotta.
- Sauce: calzones get marinara on the side; strombolis may have a little sauce rolled inside or served on the side.
- Serving: a calzone is usually one person's meal; a stromboli is sliced and shared.
Calzone vs Stromboli at a Glance
| Calzone | Stromboli | |
|---|---|---|
| Origin | Naples, Italy, around the 18th century | Philadelphia area, USA, 1950s (Italian-American) |
| Name | Italian for "trouser leg" or "stocking" | Named after the 1950 film Stromboli, itself named for a volcanic island off Sicily |
| Dough | Pizza dough rolled into a round | Pizza or bread dough rolled into a rectangle |
| Shape | Folded half-moon, edges crimped | Rolled log, seam pinched and tucked under |
| Cheese | Ricotta plus mozzarella, often Parmesan | Mozzarella, often provolone; ricotta is usually left out because it is too wet to roll |
| Typical fillings | Ham or salami, mushrooms, spinach, sausage | Layered Italian cold cuts like salami, capicola, pepperoni; peppers, onions |
| Sauce | Usually served on the side for dipping | Sometimes a thin layer inside; often served on the side |

| Bake | About 15 to 20 minutes at 450 to 475°F | About 20 to 30 minutes at 400 to 425°F |

What Is a Calzone?
A calzone is a folded pizza from Naples. A round of pizza dough is filled on one half, folded over into a half-moon, and the edges are crimped or rolled to seal. The name means "trouser leg" in Italian, a nod to how the turnover looks and how it was eaten on the go.
The classic filling is ricotta and mozzarella with salami or ham, and sometimes Parmesan, mushrooms or spinach. Sauce is usually kept out so the crust does not get soggy, and warm marinara is served on the side for dipping. In Italy you will also find smaller fried versions called panzerotti.
What Is a Stromboli?
A stromboli is an Italian-American creation. Pizza or bread dough is rolled into a rectangle, covered with layers of cold cuts such as salami, capicola and pepperoni, plus mozzarella or provolone, then rolled up into a log, sealed and baked until golden.
Its origin is usually credited to the Philadelphia area around 1950, with the name borrowed from the Ingrid Bergman film Stromboli. It is sliced crosswise to show the spiral of fillings and served as a shared appetizer or main dish, often with marinara for dipping.
Main Differences Explained
Shape and method: this is the real dividing line. A calzone is folded once over its filling; a stromboli is rolled like a jelly roll, which gives it the spiral layers.
Cheese: calzones traditionally include ricotta, which makes them creamy inside. Strombolis stick to drier cheeses like mozzarella and provolone, because wet ricotta makes the roll soggy and hard to seal.
Sauce: neither one is usually packed with sauce. Calzones almost always get marinara on the side; strombolis sometimes have a thin layer spread inside before rolling. Recipes vary, so treat these as typical, not strict rules.
How to Make Them at Home
One batch of pizza dough, like this pizza dough recipe, makes either one.
- Calzone: divide the dough into 4 balls and roll each into an 8-inch round. Spread ricotta mixed with mozzarella and Parmesan on one half, add cooked fillings, fold, crimp the edges and cut 2 small steam vents. Brush with egg wash and bake at 475°F for 15 to 18 minutes until deep golden.
- Stromboli: roll the dough into a rectangle about 10 by 14 inches. Leave a 1-inch border, layer sliced meats and cheese, roll it up from the long side, pinch the seam and ends, and place seam-side down. Cut a few slits, brush with egg wash and bake at 400°F for 20 to 25 minutes.
- Rest and slice: let a stromboli rest 10 minutes before slicing so the cheese sets.
- Safety: cook raw sausage or ground meat before filling (to 160°F), and reheat leftovers to 165°F.
- Avoid soggy dough: drain ricotta and squeeze cooked vegetables dry before filling.
When to Make Which
Make calzones when everyone wants their own, when you love a creamy ricotta filling, or for make-ahead lunches that freeze and reheat well.
Make a stromboli for game day, parties and potlucks: one log feeds a crowd, slices neatly and travels well. Serve either one with a salad or these side dishes for pizza.
Can You Substitute One for the Other?
Yes. The dough and most fillings are interchangeable. To turn a calzone filling into a stromboli, cut back or drain the ricotta and lean on mozzarella or provolone so the roll stays crisp. To turn a stromboli into calzones, divide the dough into rounds and fold instead of rolling.
Both freeze well. Bake, cool completely, wrap tightly and freeze for up to 3 months; reheat in a 375°F oven until hot in the center (165°F).

Frequently Asked Questions
What is the difference between a calzone and a stromboli?
A calzone is a round of pizza dough folded into a half-moon over ricotta, mozzarella and fillings, with marinara served on the side. A stromboli is a rectangle of dough layered with mozzarella and cured meats, rolled into a log, baked and sliced into spirals. Calzones are Neapolitan; stromboli is Italian-American.
Does a calzone or stromboli have sauce inside?
Usually neither is filled with much sauce. Calzones are typically served with warm marinara on the side for dipping. Strombolis sometimes have a thin layer of sauce spread inside before rolling, but many are also served with marinara on the side to keep the crust crisp.
Is a stromboli just a rolled calzone?
Not quite. Both use pizza dough and similar fillings, but a stromboli is rolled into a spiral log and usually skips ricotta, while a calzone is folded once and typically includes ricotta. They also have different origins: Naples for the calzone and the Philadelphia area for stromboli.
What is another name for a calzone?
Calzone means trouser leg in Italian. Small fried versions from southern Italy are called panzerotti, and in Naples a fried calzone is called a calzone fritto. In the US, calzones are sometimes sold as pizza turnovers or folded pizzas, but the stromboli is a separate, rolled dish.
Which is bigger, a calzone or a stromboli?
A stromboli is usually bigger. It is made from a large rectangle of dough, rolled into a log and sliced to serve several people. A calzone is typically an individual portion, though restaurants sometimes sell large calzones meant for sharing.
