To assemble the empanadas or turnovers, place a spoonful of the filling on the middle of each empanada disc. The amount of filling will vary based on the size of the empanada, but in general, it’s easier to seal an empanada that isn’t overstuffed. Also, the more you make empanadas, the easier it becomes to stuff them to the max and still seal them properly.
To seal the empanadas, fold the disc and seal the edges by pressing the dough with your fingers. If you’re having a hard time sealing the edges, you can use brush the inside edges with egg white, it will act as a glue for the empanadas. You can also use a fork to help seal the edges, just press the top of the fork against the edges. To the repulgue or churito, the curl type seal, use your fingers to twist the curl the edges. There are also empanada molds that you can buy and will help seal the empanadas.
For best results, I recommend refrigerating for at least 30 minutes the empanadas before baking – this also helps them seal better and prevents the filling from leaking out.
If you want your empanadas to have a nice golden finish, then you can brush them with egg wash (a whole egg whisked or egg yolk plus a few drops of water whisked).
Bake the empanadas in a pre-heated oven. I usually bake them at 375F-400F, the temperature will vary based on the oven and the size of the empanadas. I bake the smaller sized empanadas at 375F. The baking time also varies (again based on the oven and size), but it’s in the range of 18-25 minutes – the empanadas will be ready once they are golden.
