Instructions
Make the dough
In a large bowl, mix the flour and baking powder.
Add the mayonnaise and a pinch of salt.
Gradually add the cold water, 1 tablespoon at a time, mixing until the dough is soft and elastic.
Form into a ball, cover, and let rest for 15 minutes at room temperature.
Prepare the filling
In a large skillet, heat the olive oil over medium heat.
Add the diced zucchini and onion, and sauté until tender and lightly golden (about 8 minutes). They’ll finish cooking in the oven, so don’t overcook. Season with salt and pepper.
Remove from heat and let cool slightly.
In a separate bowl, whisk 1 egg. Add the grated Gouda, thyme, rosemary, nutmeg, dill, parsley, salt, and pepper.
Fold the cooled zucchini mixture into the egg-cheese mixture. Set aside.
Assemble the pie
Preheat the oven to 170°C (340°F).
Divide the dough into two equal balls. Roll each into a round disk.
Line a silicone or non-stick 24–26 cm round baking dish with the first dough disk.
Spoon the filling evenly into the base.
Cover with the second dough disk and pinch the edges to seal well.
If desired, brush the top with a beaten egg for extra color.
Bake
Place in the preheated oven and bake for about 20 minutes, until golden and fragrant.
