Thaw empanda discs overnight in the fridge. If you let them thaw at room temperature, the dough gets dry and cracks when you fill them.
To fill: gently stretch a dough disc in each direction to thin the dough. Spread 2 Tablespoons of filling in the center of the disc. Rub water or a whisked egg along the edge of half the disc. Fold in half and press to seal. Then fold or use a fork to finish.
Optionally brush the tops of each empanada with an egg wash.
Bake at 375 for 20 minutes, or until golden brown.
Notes
You can search for videos to learn empanada folding techniques. Or simply press the edges with a fork.
