Crispy Potato & Cheese Phyllo Rolls are a simple appetizer with creamy mashed potatoes and melty mozzarella wrapped in delicate layers of phyllo dough and baked until golden and crisp.
Boil the potatoes until tender. Let cool slightly before smashing. Add the salt, mozzarella cheese, and about 2 tablespoons of the melted butter. Stir to combine.
Preheat the oven to 400°F(200°C). Line a baking sheet with parchment paper.
Lay a sheet of the phyllo dough out on a work surface.
Mix the olive oil into the remaining butter. Brush mixture onto the dough.
Cut it into 4 squares. Then flip two over to double up. You should now have 2 squares.
Add about 2 tablespoons of the potato filling in a line across the long edge of the dough nearest you. Fold the ends in and roll tightly.
Bake for 15 minutes, until crispy and golden brown.
