You can make piroshki ahead of time and store them before baking in either the refrigerator or freezer. You can also refrigerate or freeze leftovers piroshki and reheat them when you’re ready to enjoy them again. Here’s how:
How to Do Make-Ahead Piroshki
To do make-ahead piroshki, follow the recipe filling the piroshki and sealing the seam. Instead of baking the piroshki, store them tightly wrapped in the refrigerator for up to five days or in the freezer for up to three weeks.
Use this as a base recipe for your make-ahead piroshki.
When you get ready to bake your piroshki, preheat the oven to 375 degrees and bake them on a lightly greased baking sheet for 20 minutes (15 minutes for ham and cheese) for refrigerated piroshki and 35 to 40 minutes for frozen piroshki or until they are golden brown.
How to Store Leftover Piroshki
Wrap leftover baked piroshki and store them in either the refrigerator or freezer as for unbaked, make-ahead piroshki. You can rewarm your piroshki either in the microwave or in an oven set at 200 degrees. (If the piroshki is frozen and you are heating them in the microwave, set the microwave on a low setting or defrost setting.)
Heating the piroshki in the oven will create a crisper crust than heating them in the microwave. For those heated in the microwave, you can crisp the crust by placing the piroshki in a toaster oven for three to five minutes.
