Strain ricotta a day or few hours using strainer/cheese cloth to prevent crust going soggy - see "top tip for making calzones" above for details
Preheat the oven to 425°F, prepare egg wash
Divide dough into 4 portions, pat into round discs, then roll out or shape into circles ¼ inch thick
Spread 2-3 tablespoons of marinara onto one half of the dough (if using) then sprinkle over cheeses, leaving ½ inch around the edge
Brush the egg wash around the edge of the dough then fold dough over and seal
Place calzones onto a lined baking sheet or pizza stone
Brush with egg wash then cut 3 slits in the top to release the steam and sprinkle with remaining parmesan
Bake in the oven for 15-20 minutes.
Remove from oven, allow to rest and cool , then slice in half
Dip in marinara sauce or favorite dipping sauce and enjoy!
