Breakfast Casserole with Spinach, Bacon, and Mushrooms

Our hens are laying a bunch of eggs. Everyday we’re getting about a dozen or so and are giving away eggs to family, friends, and people we meet on the street. I exaggerate, but only slightly. Breakfast casserole recipes have been some of my favorite recipes to make lately. Nothing fills my family up and keeps them going like a delicious breakfast casserole.


This time, I made a Bacon, Portabello, and Spinach Breakfast Casserole.

And it was some kind of yummy. It’s a must-make around here now.

Here’s how I make it.


Start with eggs. Imagine that.


Aren’t they pretty? Give them a quick whisk.


Grab some bacon and cook it until it’s just the way you like it — extra crispy or a little flimsy. Your choice.

Rough chop the bacon and throw it in with eggs.


Chop up about two cups of mushrooms and toss with the eggs.


Next goes in chopped spinach. I love spinach, so I used about 3 cups.


Pour in 1/2 cup of melted butter.


Throw in a cup of shredded cheddar cheese. I use sharp. Give it a quick mix.


Pour into a casserole dish that has been sprayed with non-stick cooking spray.

Bake for about 30 minutes on 350 degrees.


Remove from oven and let stand for about five minutes. Serve warm and enjoy.

    This looks delicious! Only question: in your written directions, it says to only bake for 15 minutes. That seems awfully short. Then in the recipe card, it says 30 minutes. Do you have a more definite time for baking? Can’t wait to try this! Thanks for sharing. :)
