This savory vegetable quiche is a delightful dish perfect for any meal of the day. Packed with fresh vegetables and a creamy egg mixture, it's both nutritious and delicious.
Preheat your oven to 450°F (232°C).
Ensure the oven is fully preheated for even baking.
Line the pastry shell with foil and bake for 5 minutes.
This step helps to prevent a soggy crust.
Remove the foil and bake the crust for an additional 5 minutes.
Keep an eye on the crust to avoid over-browning.
Reduce the oven temperature to 325°F (163°C).
Allow the oven to cool slightly before adding the filling.
In a mixing bowl, whisk together the eggs, milk, salt, pepper, and nutmeg.
Whisk thoroughly to ensure a smooth mixture.
Add the spinach, mushrooms, and onion to the egg mixture and stir to combine.
Ensure the vegetables are evenly distributed.
Toss the shredded cheese with the flour and add it to the egg mixture, stirring well.
Coating the cheese with flour helps it integrate better into the mixture.
Pour the filling into the prepared pastry shell.
Pour slowly to avoid spilling.
Bake the quiche in the oven for 35 to 40 minutes, or until the center is set.
Check for doneness by inserting a knife into the center; it should come out clean.
Let the quiche cool for 5 minutes before slicing and serving.
Cooling allows the filling to set for easier slicing.
