Perfect Breakfast Casserole - everything you love about breakfast in one easy and delicious casserole! Bacon, sausage, mushrooms, peppers, onions, hash browns, eggs and cheese. This breakfast bake is perfection!
This breakfast bake is perfect for the holidays, just like my Cinnamon Roll French Toast Casserole or Sausage Gravy with biscuits.
I shall call this the ultimate breakfast casserole. It has everything we love about breakfast (the savory type) and is so satisfying, it's perfect for a holiday morning or a weekend. Bacon, sausage, mushrooms, peppers, onions, potatoes, eggs and cheese. All of rolled into one casserole. It is my go-to dish for holiday breakfast or snowy weekend. It fills you up so you can enjoy the planned activities. On Christmas morning, I know that breakfast will be the last thing on our kids' minds and they will be busy playing afterward. I need to make something that will make their bellies happy for a while!
Ingredients (your shopping list):
- bacon
- pork sausage
- red and green bell peppers
- sweet onion
- garlic
- mushrooms
- 24oz bag of diced hashbrowns or potatoes O'Brien
- shredded mozzarella and cheddar
- eggs
- milk
- salt and pepper
How to make it?
-
Place potatoes in a large mixing bowl.
-
In a large skillet, cook bacon until almost all pieces are crispy. Add sausage and cook until done. Add garlic and all diced veggies (onion, peppers and mushrooms). Cook until onions are translucent.
-
Add the sausage veggie mixture and half of the cheese to potatoes and stir in gently. Spread the mixture in a baking dish.
-
Whisk together eggs and milk. Add salt and pepper and whisk together. Pour the egg mixture over potatoes. Sprinkle remaining cheese over the top.
-
Bake until sizzling and the cheese is melted.
Can I make it ahead of time?
To make this breakfast ahead, I recommend thawing the potatoes in the bag in your fridge. Cook the veggies and sausage, cool and place in an airtight container. In the morning all you need to do is mix everything together, whisk eggs with milk, pour over potatoes and bake it all together. Everyone will be happy to sit down to this goodies filled breakfast!
