Easy Vegetarian Mushroom Calzone

By | January 3, 2015

Mushroom CalzoneThis mushroom calzone is a great winter warmer. It’s easy to make, but looks great. I use Gorgonzola and buffalo mozzarella if I’m shopping from scratch, but I’ll often substitute leftover Stilton and Brie into the mix instead during the Holidays. Feel free to mix up your cheesy ingredients to match your tastes.

I prefer to use ugly mushrooms for this one, field, portobello, or just button mushrooms that have past their best. You tend to get a better flavor with ugly mushrooms. If you are feeling fancy, or considering serving this mushroom calzone as a vegetarian alternative for a family holiday meal then do glam it up a little using fancier mushrooms like oyster.

Home made pizza dough tastes great, is easy to make and you have the confidence of knowing exactly what’s gone into and onto your pizza. Make the task easy with an entry level bread machine. It’ll pay for itself really quickly.


  1. Make the pizza dough if using your own
  2. Form dough into a 12″ circle and put aside
  3. Heat the oven to 450F, 230C, Gas 8
  4. If you have a pizza stone put the stone in the oven, if not, grease a large cookie sheet
  5. Finely chop the onion and garlic
  6. Chop the mushrooms into 1/2″ pieces
  7. Chop the cheese into 1/2″ pieces
  8. Heat 1 tbsp butter in a large skillet
  9. Add the onion and garlic and soften over a medium heat for 4-5 minutes until transparent
  10. Remove the cooked onion mix and set aside
  11. Add the second tbsp butter to the pan, add the mushrooms and cook for 3-4 minutes until softened and juicy
  12. Turn off the heat
  13. Add the onions back in and mix, then add the cheeses and mix some more
  14. Put the mix in a half moon shape on the pizza dough, leaving a 1″ gap at the edge and leaving half of the dough uncovered
  15. Fold the empty half over the filling and crimp the edges to seal the filling in
  16. Transfer the calzone to the hot pizza stone or grease cookie sheet and return to the oven for 12 minutes
  17. Once cooked you can brush with olive oil to make it shine, or leave it natural
  18. Serve with fresh salad leaves.

A pizza stone makes for crisper, more evenly cooked pizza, whether you’re making your own fresh, or just heating one up straight out of the freezer. Treat yourself to a pizza stone for a lifetime of crisper pizza.

Transferring your home made pizzas and calzones from preparation to oven to serving plate can be a bit tricky, leaving your lovingly crafted meal looking less than perfect. A good pizza peel makes the task much easier, and this one looks great too.
