French Toast Casserole Taste Testing in Progress

With the blessing of so many eggs from our chickens, we are test tasting several French Toast Casseroles.  I have recipes for many egg dishes, but not for this type of casserole.  Many of the recipes require 4 to 12 eggs to make.  We are thrilled to give these a try.  We have 2 from the Internet that are being baked this weekend.  The trouble I am having, is finding a very healthy recipe.  Many require cream and butter.  Without other farm animals, I would have to buy these items.  I'm seeing more benefits of adding goats, cows, pigs, and other animals.
