Experiment tonight

Decided to make a quiche that was more similar to a frittata.
Make a crust of mashed potatoes in a 9/10 inch nonstick frying pan.
Then use caramelized onions and mushrooms on that. Then poured in the egg, cream and cheese mixture.
Baked at about 275.

Worked very well. gluten free for those who worry about that.

Next time, I will bake the crust a little first to give it some color on the bottom.

1. How do you make a mashed potato crust?

That sounds good.

2. I took the cooked potatoes

5 medium. Mashed with a little pepper and a bit of butter and a bit of the cream for the quiche.
I wanted them a bit firm.
I just spread the potatoes into and up the sides of the pan about 3/4 way up with a wooden spoon.

3. I gather you didn't bake the crust this time

But you think you will in the future. I don't imagine it would need pie weights, like par-baking a flour and shortening crust.

Thanks.

4. One of the reasons

to try this was I never seem to be able to blind bake a crust and not have it shrink up all over. The sides pull down with he baking. My mother used to just dock pie crusts and had no troubles that I remember.
Pre-cooking the crust a bit will reduce moisture going into the potatoes also when the quiche is added. I could also in the prebake state add a bit of Emmenthaler to make a thin layer when it bakes.

5. I line the crust along the bottom and up the sides with foil

Then, add beans. I have the beans to reuse for this purpose. I've been pretty successful at that.

6. It's been several years, but I've done something similar

with very thinly sliced potatoes lining the skillet. You're right, baking the crust a little first works great.

7. Try mixing the onion into the potatoes, or even using uncooked onion

Use a coating of oil (spray on is fine) in the frypan to get that Maillard reaction going a little faster.

You'll end up with a quiche inside a crunchy potato cake and that sounds great to me.
