I know this is many years late, but I hope that someone will have an answer. I am also cooking what "could" be called quiches in muffin tin cups. The recipes call them Egg Muffins, my boss says they look like quiches.
So, several years ago I bought a silicone muffin pan, greased the cups, the eggs stuck and were hard to clean. Eventually we tossed the silicone pan, as I could never get it clean enough to use again.
Last night I used a metal muffin pan with paper liners, greased. The eggs stuck to the paper liners and made a mess, plus there was a lot of egg lost. The muffin pan was easy to clean, though, just greasy.
I am wondering about cutting non-stick foil into squares to insert into the muffin cups - has anyone tried this? I am desperate to find some way to cook these where I don't get so frustrated I quit making them. They are very helpful with my diabetic diet.
Any other suggestions would be lovely. Thank you.
If needed: Generally, I mix some kind of chopped, cooked meat (sausage, ground beef, bacon, ham) with a variety of stuff: grated cheese, frozen spinach (thawed, squeezed), sauteed onion, chopped mushrooms, sun-dried tomatoes, scallions, etc. Spoon some into the muffin cup, pour beaten egg over it.
