Mornings are NOT Mornings without Breakfast Casseroles
I am a Morning Person. And, I need a BIG sit down breakfast before I start my day. I am SORRY! I cannot suffice myself with a Cinnamon Apple Quinoa Breakfast Bowls or a Strawberry Banana Smoothie. I need real food. Something that's cheesy, bubbly, delicious and LOADED with carb! 😜
Although I love to add crispy bacon, Hashbrowns, and Pre-cooked Italian Sausages into my Breakfast Potato Casserole.
But, these days, I have been trying to eat less meat. And therefore I decided to make this egg and potato breakfast casserole without any meat.
This recipe is simply perfect for a day when you are hosting a large dinner for a group of friends or simply making dinner for your family.
When I am not making Breakfast casseroles my mornings are usually packed with Pancakes or Coffee Cakes or Cinnamon Rolls or Smoothies or any other healthy drinks.
But, somedays! You just feel like binge eating! And, that's when we make Breakfast casseroles.
FYI: This makes an excellent weeknight dinner as well. Especially on the days when you are super-busy! (did I hear - always! 😁)

- Add Hashbrowns - Cubed and Thawes hashbrowns makes a perfect addition to this breakfast casserole.
- Add Tatertots - Instead of Hashbrowns you can add Tatertots.
- Diced ham - Instead of Sausages you can use diced Ham.
- roasted Mushrooms - Not a fan of meat but want that meat-y texture, try adding some roasted Mushrooms!
Storage
Baked or unbaked Breakfast casseroles are super-friendly when it comes to storage.
Refrigerate:
If you've baked it then cool it down completely. Cut it into individual servings and store it in an airtight container. Refrigerate for 3-4 days.
Freeze:
You can freeze them for up to 2-months.
Reheat:
The best way to reheat your Egg and potato Casserole is to transfer it to an preheated oven at 375 degrees F and heat it for 10-15 minutes or until completely warmed through.
How to tell if my Casserole is Cooked through?
Use a fork to pull out some potatoes from the center of the casserole. Check if its done. It should be tender and completely cooked through.
If not, cover with a foil and bake for an additional 5-7 minutes.
