In a large nonstick skillet, heat oil over medium. Add onion; cook until softened, 4 to 5 minutes. Add broccoli, garlic, and pepper flakes. Cook, stirring occasionally, until liquid has evaporated, 5 to 7 minutes. Transfer to a medium bowl; set aside to cool.
Preheat oven to 400 degrees. Form calzones: Divide dough into 8 equal pieces. On a lightly floured surface, stretch each piece out, first to a 3-by-4-inch oval, then stretch again, this time to a 6-by-8-inch oval. (Let dough rest a few minutes if too elastic to work with.)
Stir cheeses into cooled broccoli mixture; season generously with salt and pepper. Assemble calzones: Spread a rounded 1/2 cup broccoli mixture over half of each piece of dough, leaving a 1/2-inch border; fold over to form a half-moon. Press edges to seal. With a paring knife, cut 2 slits in the top of each calzone.
Using a wide metal spatula with a thin blade, transfer calzones to 2 baking sheets lined with parchment or waxed paper; reshape if needed.
Bake until golden, about 25 minutes. Serve with tomato sauce, if desired.
To freeze: Prepare recipe through step 3. Tightly wrap each calzone in plastic; freeze until firm. Transfer calzones to resealable plastic bags; label and date. Freeze up to 2 months. To serve, unwrap calzones, and place on parchment-lined baking sheets; bake without thawing until golden, 35 to 40 minutes.
These are so good and super easy. I thought they might need something else to add some oomph, but they are great just as is. I used a jarred tomato and basil pasta sauce for dipping and it was delicious.
This was great! I made my own pizza dough (Ina Garten's recipe) with whole wheat flour and it was delicious!
Yummy, and the kids ate it without complaining. Next time I'll add some meat.
Great recipe! Though I actually made this with only 1 package of broccoli and a 9 oz pack of Italian chicken sausage, sliced. It was delicious, and fun to make.
This recipe was excellent. I made my own dough, and it turned out fantastically. Definitely a quick and easy go to meal.
Very easy and tasty make ahead dinner idea. With groccery prices going up this is a nice meal for any family budget. Label your freezer bag with the date and cooking instructions.
