This easy breakfast casserole is a complete meal with eggs, potatoes and sausage. This gluten free and clean eating recipe with overnight option makes a perfect Christmas morning breakfast. After a late Christmas Eve, it’s so convenient to feed hungry bellies with a hearty meal with no morning prep.
VIDEO: HOW TO MAKE THIS OVERNIGHT BREAKFAST CASSEROLE
Before we go into the details of how to make the best breakfast casserole and how I’ve made this one healthier, let’s talk about family, food and the holidays and how they all connect.
For my family Christmas dinner is always a big deal. Most years my sisters and I (and our families) gather at our parent’s house and – together – prepare a LOT of food. My mom loves to cook big amounts for special occasions, so that there are guaranteed to be leftovers.
Which pretty much equals no cooking for at least 2 days after a big Christmas dinner.
It also means, if something doesn’t quite turn out as planned, there are always other options to fall back on. This is exactly what happened to our Christmas dinner 2 years ago when we had one of those #ScrambledPlan mishaps.
That year, a roasted goose was part of the dinner menu (goose is a German Christmas tradition), but something went wrong with it. The goose seemed tough, but also not quite cooked through at the same time. Maybe it was an old one?
Thanks to the many other dishes on the table though, no one had to go hungry at that Christmas dinner.
This isn’t where the #ScrambledPlan story ends. The die-hard frugal she is, my mom tried to salvage the goose roast for lunch the next day. So she returned it to the oven first thing in the morning.
I happened to be in my first trimester of pregnancy with Olivia. Food was an iffy subject for me at the time, especially in the mornings. No one really appreciated waking up to the aroma of roasting goose – me least of all.
I woke up sick to my stomach and was on the run for the bathroom the next second.
I don’t even remember if she managed to salvage the goose. Because there was no way I was going to have even a bite of it. Thankfully, there were plenty of other leftover options (with less penetrating aromas) for me to enjoy.
Healthy Breakfast Casserole With Potatoes
So no, I am not sharing a recipe for roasted goose in this post. Instead, I have an easy Breakfast Casserole with Eggs, Potatoes and Sausage. It’s a delicious, hearty egg breakfast recipe baked all in one pan that the whole family (hopefully, even if pregnant) will truly enjoy.
I am calling this breakfast bake healthy, because unlike most breakfast casserole recipes, it is made entirely from scratch and with only whole food ingredients. Instead of frozen hash browns, I make this breakfast casserole with fresh potatoes that are shortly boiled before baking.
I even make my potato breakfast casserole with sausage that I flavored myself by simply mixing ground pork with spices. And as with all shredded cheese recipes, I also recommend shredding your own from a block of cheese for this sausage egg potato casserole. It’s so quick and easy to do (and cheaper), while you get to avoid all the added stuff (wood pulp etc.) in pre-shredded cheese.
How to Make Breakfast Casserole the Night Before?
This egg casserole recipe can also easily be turned into a make-ahead breakfast casserole, which is perfect to serve to guests who are staying overnight during the holidays. You can completely prepare everything the night before. In the morning, all you do is take the sausage egg casserole from the fridge and pop it in the oven.
Half an hour later a complete breakfast is ready to be served. Well, you should probably brew a pot of coffee (or tea) as well and some crusty bread with this sausage potato egg casserole is never a bad idea either.
I am sharing this recipe and my #ScrambledPlan holiday story as part of my partnership with the Egg Farmers of Canada.

Breakfast Casserole with Eggs, Potatoes and Sausage
- 20 ounces 600 g potatoes, peeled & cut into 1/2 inch cubes
- 1 pound Italian sausage*
- 1 onion diced
- 1 red pepper diced
- 3 garlic cloves minced
- 2 cups shredded mild cheese from a block of mozzarella or mild cheddar
- 6 eggs
- 1/3 cup milk
- 1/4 teaspoon black pepper
- sliced green onion
- Preheat oven to 375 degrees F. Cook the potato dices in salted boiling water for about 5 minutes. Drain and let cool.
- Remove casings from sausage, unless you are making your own mix like me. Heat a skillet to medium-high and cook the sausage until browned. Break it up in the process. Remove from skillet with a slotted spoon. Leave 1 tablespoon of grease.
- Cook the onion and red pepper in the sausage grease for about 5 minutes. Add the garlic and cook a couple more minutes. Fill into a large baking dish (9x13 inches) together with sausage and potato dices.
- In a bowl, whisk together the eggs, milk and black pepper and pour into the baking dish. Add 1.5 cups of the shredded cheese and stir to combine everything.
- Sprinkle the remaining cheese on top, cover with foil and bake for 20 minutes. Uncover and continue baking for 10-15 more minutes.
- Let the breakfast bake rest for a few minutes. Add sliced green onion and serve hot.
*1. You can use any kind of breakfast sausage for the recipe - spicy is good. I make my own breakfast sausage by thoroughly mixing with my hands 1 lb ground pork, 2 t Italian spice mix, 1 t each salt + pepper, 1/2 t each cayenne + nutmeg. Making it myself guarantees that there aren't any strange fillers or allergens (like gluten) in the sausage.
2. Overnight option: You can prepare this casserole the night before. Fill everything into the casserole dish, sprinkle with cheese, cover the dish with foil and refrigerate overnight. In the morning, continue with the baking instructions in step 5.
