You can also change up the type of cheese to give this a completely different taste.

Of course, you can also add meats and or use vegan cheese for a vegan stromboli. For this recipe, I used a store-bought pizza dough. If you don’t want to use store-bought pizza dough a great option is to buy pizza dough from your favorite local pizzeria. You can always just make your own pizza dough from scratch. There are lots of pizza dough recipes out there and one of my favorites is this pizza dough recipe from Joy Food Sunshine.

We love making this mushroom and spinach stromboli for dinner but it’s also a great picnic food. We often take it with us when we’re spending a day at the beach or the park as it’s easy to transport and easy to eat too. It’s delicious directly out of the oven but it’s also really good cold so it’s the perfect food for taking on road trips or for snacking. 

What is a stromboli

A stromboli, sometimes also called a pizza roll, is a close cousin to the Italian calzone and pizza. Usually made with pizza dough, it’s filled with the usual pizza toppings including Italian cheeses like mozzarella and provolone as well as Italian meats or in this case your favorite vegetables. The pizza dough is rolled up with all of the filling ingredients inside and then baked until golden brown and crispy. 

Stromboli is easy to eat with your hands and perfect as an appetizer too. It’s an easy dinner recipe that is as versatile as pizza because you can change up the ingredients for the filling to fit your taste or what you have available at home.

What is the difference between calzone and stromboli

The main difference between calzone and stromboli is that the calzone is made with pizza dough folded over the filling ingredients like a hand pie while the stromboli is rolled. 

The calzone and the stromboli also have different origins. The calzone is a traditional Italian food while the stromboli was invented in Philadelphia. 

How to make the best stromboli

The key to making a fantastic stromboli or pizza roll is starting with great pizza crust. There are a few different pizza crust options at the grocery store. If you’re going for store-bought pizza crust make sure you buy the best quality pizza crust you can get your hands on. It makes a huge difference. For even better results call your favorite local pizzeria to find out if they will sell you pizza dough! 

When it comes to the ingredients for the filling you can get as creative as you want to. Some suggestions include:

Meats

  • salami
  • pepperoni
  • ham
  • bacon
  • sausage

Cheeses

  • mozzarella
  • provolone
  • cheddar
  • Havarti

Veggies

  • onions
  • green peppers
  • spinach
  • mushrooms
  • banana peppers
  • black olives

I like to serve the stromboli with marina sauce on the side for dipping but you can also add the marinara sauce inside the stromboli. If you do add the marinara to your stromboli do make sure you are not adding too much as you don’t want your pizza dough to become soggy.

If you are using veggies that might give off a lot of liquids when cooking like tomatoes or mushrooms it’s best to cook them before adding them to your stromboli. You don’t want your pizza dough to get soggy.
