How to Make Spinach Bacon and Mushroom Breakfast Casserole

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 sharp cheddar cheese. Give it a quick mix.

Pour into a 9×13 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.
