There are many combinations and options for a veggie pie or quiche, but sometimes you feel like making something a bit different.
While thinking about dinner for the family that will not consist of the traditional dishes we usually have, I came up with this great recipe for baked mushroom squares. It was tested, tasted, and it’s really good so I decided to share:

Frequently Asked Questions
What makes the base different from a standard pastry crust?
The base uses eggs and melted butter mixed into flour with baking powder — more like a dense, tender cake batter than a flaky pastry. It is baked first for 20 minutes until golden, cooled, then spread with cream cheese before the mushroom topping goes on.
Why is cream cheese added between the base and the mushroom topping?
The cream cheese layer acts as a barrier that keeps the baked base from absorbing moisture from the mushroom-egg mix, helping the squares stay firm. It also adds a mild tangy flavor that balances the savory topping.
How do I know when the mushroom squares are fully baked?
The recipe says to bake at 350°F for about 30 minutes until golden brown and firm to the touch. The egg in the mushroom topping sets as it cooks, giving the squares their structure.
