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!
Freezing
Already prepared breakfast casserole can be frozen for up to 2 months. When ready, place it in the fridge to thaw, then bake in 350 degrees F until heated all the way through.
Storing
Any leftovers should be stored in a container with lid, in the fridge, for up to 3 days. Heat up in the microwave or oven.

Sarah says
Do you think lowering the temperature to 350* will affect the outcome of this dish if it just baked it longer? I have another dish that needs to go in, but the recipes calls for the oven to be set to 350*.
I made this casserole for Christmas morning and halved the recipe. It was delicious and the eggs were barely noticeable - which is what I prefer!
Anna@CrunchyCreamySweet says
Hi Sarah! Thank you so much for making my recipe! I am so happy to know you love it! I think it should be just fine at 350 degrees F and baked longer. Enjoy!
Anjee says
Hello. What a wonderful casserole. Wondering if I made it it in advance and froze it. Would love to make for our beach vacation.
Anna@CrunchyCreamySweet says
Hi Anjee! It should be just fine. Make sure to wrap it tight before freezing. Have a beautiful day! -Anna
Shelly Edison says
Wonderful- looking recipe- I imagine adding a Dijon Hollandaise Sauce on top- Salivating just thinking of it. Thanks for the recipe.
Mia Flores says
Hello,
This looks so amazing! My one question is, do you think I can omit the cheese? My husband and daughter do not eat cheese, si Iwas wondering what you think about the cinsistency if I left it out?
Thank you
Anna@CrunchyCreamySweet says
Hi Mia! You can absolutely skip the cheese. The casserole will still be awesome! 😀 Hope this helps! Have a beautiful day! -Anna
Joan says
Hi there. Do you think that you could assemble the night before and then just pop it in the oven when you get up?
Anna@CrunchyCreamySweet says
Hi Joan! Thank you for the question! Yes, you can definitely make it the night before. I like to place the veggies and sausage in the casserole dish and the eggs and milk whisked together in a separate container and before baking pour them over the casserole and top with cheese. Hope this helps! Let me know if you make it. Have a beautiful day! -Anna
