Spinach Potato Mushroom Breakfast Casserole. Because this dish contains eggs, it is labeled as a breakfast casserole, but everyone knows that eggs and breakfast are perfect for any time of the day or night. This casserole uses all the basic casserole favorites--eggs, spinach, onions, potatoes, and mushrooms.
The shredded potatoes give the casserole kind of a hash brown texture, and when combined with the vegetables, it has everything you need for a delicious, filling, and oh-so-easy meal.
If you prefer a vegan option, simply omit the eggs and you can still enjoy the deliciousness.
The great thing about casserole dishes is that you toss all the ingredients into one pan, and you can either bake it immediately or refrigerate it for baking later. A one-pan meal like this recipe or like this chicken fried rice and greens recipe is perfect for easy cleanup! Fewer dishes used is always a good thing!
This one-pan cooking convenience makes this casserole perfect for special events, or Christmas morning breakfast. Using basic ingredients, you will be ready to dig into this yummy dish within an hour.
For busy weeks, this recipe can be made ahead of time. Follow the directions right up until baking, cover, and place in the fridge, and when you are ready to eat it bake and enjoy!
