1. Prepare the Dough
In a small bowl, dissolve the yeast and sugar in warm water. Let it sit for 5–10 minutes until frothy.
In a large mixing bowl, combine flour, salt, and garlic powder. Add the yeast mixture and knead until a soft dough forms.
Cover and let the dough rest for 1 hour, or until it doubles in size.
2. Prepare the Filling
In a bowl, mix the mashed potatoes, shredded mozzarella, melted butter, minced garlic, salt, and black pepper.
Stir well to combine, ensuring the potatoes are creamy and well-seasoned.
3. Shape the Pide
Preheat the oven to 400°F (200°C).
Roll out the dough into an oval shape on a floured surface.
Spread the potato-cheese filling in the center, leaving about 1 inch of space along the edges.
Fold the edges inward, pinching the ends to create a boat-like shape.
4. Bake to Perfection
Brush the edges of the pide with egg yolk and sprinkle sesame or nigella seeds if using.
Transfer to a parchment-lined baking sheet and bake for 18–20 minutes, or until golden brown and crispy.
5. Serve and Enjoy
Let it cool slightly before slicing. Serve warm for the ultimate cheese pull!
