Puff Pastry Onion Casserole
55 min (your 15 min)
Lightly flour the cutting board and roll out the dough. We transfer it to the mold, pierce it with a fork in several places (so that it does not rise when baking).
Heat vegetable oil in a frying pan, add onion, cut into rings, red and green peppers, cut into cubes, and simmer, stirring occasionally, for about 20 minutes. Put the filling on top of the dough into a mold. Heat the oven to medium temperature (180 ° C).
Sprinkle the filling with crumbled feta cheese on top. Mix an egg with milk in a glass and fill the filling with this mixture. At the end, sprinkle everything with grated Parmesan.
Bake for 30-40 minutes, until the casserole is browned.
