Crustless Spinach QUiche

Where this quiche recipe came from

Years ago I worked with a close friend who did weekend retreat counseling sessions. I would go and cook the food for those who were attending. One of the other workers there would make this quiche, and it quickly became one of my favorite recipes ever.

This Crustless Spinach Quiche recipe became so popular with those who attended the weekend sessions that it became a permanent brunch item on the menu.

It also was one recipe I was certain I had at home! If there were any leftover from the weekend, I was happy to take some home with me. The family was always happy to enjoy the warmed up quiche.

Fresh Spinach or Frozen Thawed Spinach

Large Eggs

All-Purpose Flour

Cheddar Cheese: I prefer brick cheese that I shred myself, but pre-shredded will work also.

Milk – I use almond milk because it has a longer shelf life. However, any milk you have in your home will work.

Nutmeg: I use whole nutmeg and grate it fresh with a microplane zester.

9 inch pie dish – this is my favorite one to use.

Tips for a successful quiche

  • Whisk the wet ingredients with the onion in a separate bowl.
  • Stir together the dry ingredients with a whisk to be sure the salt and baking powder are incorporated evenly.
  • Be sure to squeeze the spinach to release all of the water before stirring it into the batter.
  • When stirring the flour mixture in, use a whisk to help break up any lumps of flour.
  • Test the quiche for doneness by inserting the tip of a knife in the center of the quiche. If it comes out clean, the quiche is cooked.
  • Use a brick cheese and shred it yourself instead of buying pre-shredded cheese.
