Cover the mixture with shredded cheese. I opted to use pre-shreded Mexican cheese blend I had in my fridge, but use whatever speaks to ya. In the recipe I read online it called for American cheese, so do whatever works! Then add the remaining eggs on top of the cheese, evenly distributing them over the surface. Put in the oven for 11-13 minutes (more depending on your baking dish and oven). Enjoy!
My comments: delicious! I made the mistake of covering mine when it was still hot so the leftovers were not as crispy as I would have wanted. Heading forward when I make again, because I am gonna make it again, I would put cheese on the top of the quiche and leave it in the oven for a little bit more time. I got this recipe idea from the internet but adjusted to fit my palate and what I know about baking eggs. Yummy yum yum!
