Just like in our Cowboy Breakfast Skillet and Bacon Breakfast Casserole our family loves when cheeses are blended with other classic breakfast ingredients.

I love how there’s a lot of vegetables in this breakfast dish, but the meaty bacon and cheesy flavors all compliment each other so well. Our Egg, Sausage & Brioche Breakfast Casserole and our Everything Bagel Breakfast Casserole also blend wonderful and unique flavors in every bite.

Tips & Tricks

  • Spinach should be defrosted and well-drained. Toss into a strainer and squeeze handfuls so that all of the juice is squeezed out.
  • If fresh spinach is used ensure that it is well-drained to prevent a soupy quiche.
  • Flour is used to help thicken up the milk and help ingredients stick together.
  • Freshly shredded cheeses maximize fresh flavors, but pre-shredded cheese may also be used.
  • Quiche is done or set when the center stops jiggling when bumped and when a serrated knife inserted in the center comes out clean.

Can Fresh Spinach Be Used Instead of Frozen Spinach

Fresh spinach that has never been frozen or wilted creates more volume in the same amount of weight as frozen spinach. Therefore fresh spinach is more challenging to get mixed in to the other ingredients.

When an equal amount of fresh spinach is used as frozen spinach, pieces will pop up on top and may burn while baking. So the solution is to decrease the amount of fresh spinach slightly, add wilted fresh spinach to the recipe, or chop spinach well before mixing in.
