Start by cutting up your onions and mushrooms and put them in a frying pan with your butter. I do this on a medium heat for about 10 minutes.
You know they are done when the onions look kind of translucent. The veggies also shrink a little too. Now put this aside.
Take the eggs, milk and cheddar cheese in a mixing bowl and give it a go until it is mixed well. Now put this aside for a moment.
Start preparing your Brie by slicing it in strips. Brie is so soft and you can't grate it, this is the only way. Once your done doing that put it aside with the egg mixture and mushrooms and onions.
Now I was to lazy to make crust, it was to late at night for me to run to the market so I brainstormed and I decided to take a splash of oil ( I used olive) and I greased the pie dish with that and then I sprinkled Parmesan Cheese over the oil to give it the floured over look. This is yummy and wont burn and gives the quiche a crust effect without crust and it doesn't burn and it lifts out of pie dish easily.
Next I start by putting the egg mixture in half the pie dish and then I spoon the mushroom and onions on top. Lay the brie in strips on top. (please note, do not mix together!!! I know it seems easier but the end result is so much better this way!)
Now take and cover the onions and mushrooms and Brie with the remaining egg mixture.
Once the pie dish is filled take the remaining Parmesan cheese and sprinkle on top. Now time to preheat your oven to 375 and take a moment for yourself. :)
Once the oven is preheated to 375 carefully put in the oven. As you see I have foil in mine. You don't have to do this, I am such a klutz I just didn't want to have spillage in my newly cleaned oven haha! Bake for 30-35 minutes.
When your 35 minutes are up, do the knife test to make sure its cooked through. If you see it jiggle badly it's not ready yet. If it has a very slight jiggle and it is golden brown...Your all done! I like my quiche hot but my son likes his cold. In any event slice and put on plate and add a dollop of sour cream and say WA la! I did it like the french! Bon Appetite! This is a great easy quiche and you can add so many things to it, but the more cheese the better!!!
