How to Make Mushroom & Spinach Quiche

Preheat your oven to 375°F (190°C) to ensure even baking heat, allowing the crust to turn golden and the quiche to set beautifully without soggy spots.
Make the crust by combining flour and salt, cutting in chilled butter until pea-size crumbs form, then slowly adding cold water and mixing just until a dough holds.
Chill the dough by wrapping it tightly in plastic wrap and refrigerating for at least 30 minutes to firm the butter for a flakier texture when baked.
Roll out the chilled dough on a lightly floured surface into a 12-inch circle, fit it into a 9-inch quiche pan, trim edges, and prick the bottom with a fork.
Blind bake the crust: line with parchment, fill with weights or beans, bake 15 minutes, remove weights, then bake an extra 5 minutes until the base looks dry and set.

For the Filling:

Sauté vegetables: heat olive oil over medium heat, cook onions and garlic until translucent and fragrant, add mushrooms, cooking until golden and moisture evaporates, then stir in spinach until just wilted.
Whisk custard: in a bowl, combine eggs, heavy cream, salt, and pepper, whisking until smooth and well blended, creating a silky mixture that will set perfectly.
Assemble quiche: spread mushroom-spinach mixture evenly over the crust, sprinkle grated cheese on top, then pour egg-cream custard over to fill just below the rim.
Bake quiche: bake at 375°F for 30–35 minutes, until the custard is set but still slightly jiggly in the center, and the top is lightly golden brown.
Rest & serve: let the quiche cool on a wire rack for 10 minutes to set, then slice into wedges and serve warm or at room temperature.

Optional: Garnish with fresh thyme before serving.
