Easily feed a crowd with this 5-minute prep breakfast potato egg casserole – a family favorite and the perfect make-ahead meal!
Prepped in 5!
We have breakfast for dinner at least ONCE a week because we love breakfast that much! Breakfast casseroles are one of our go-to’s because they’re so simple and today’s recipe for potato egg casserole is one of our favorites.
We first made this for a holiday breakfast years ago and have had it on repeat since. It’s filled with cheesy potatoes, eggs and sausage and is so delicious and simple (it’s prepped in 5 minutes!)
As with most casseroles, this is perfect for making ahead of time for an easy morning (think holidays or busy weekends). Even so, it’s simple the morning of – just mix and bake and it’s ready in 40 minutes!
Pair it with a sweet casserole like Coffee Cake or Cinnamon Bites for a complete meal.
WHY WE LOVE IT:
- Filling. This particular casserole has potatoes, eggs, sausage, and cheese – some of our favorite hearty breakfast or brunch ingredients.
- For an easy morning. This egg bake is prepped in 5 minutes and on the table in 40 for a less-fuss way to start your day.
- Prep the night before. Store in the fridge or freezer until you’re ready to bake – perfect for holiday mornings!
Ingredients
PREP TIME: 5 minutes
COOK TIME: 35 minutes
- 8 large eggs
- ½ cup milk, room temperature
- 1 (20-ounce) bag of frozen diced hash browns, thawed – To use fresh potatoes, peel and dice 20 ounces of russet potatoes – do not soak (the starch will thicken the casserole).
- 9-10 ounces precooked Italian sausage – You can brown raw Italian sausage in a skillet before adding the recipe.
- salt and pepper, to taste
- 1½ cups shredded mild cheddar cheese, divided – Substitute or combine it with Swiss cheese, pepper jack cheese, or Colby Cheese.
- optional garnish – fresh herbs and spices like parsley and green onions or a dollop of sour cream
Flavor Variations
- MEXICAN. Add chopped peppers and use Mexican blend cheese.
- MEAT LOVERS. Add cooked bacon along with the sausage.
- VEGGIE. Replace meat with a cup of chopped spinach, mushrooms, zucchini, red bell pepper, or broccoli florets. Sauté veggies in a large skillet before adding.

I love this casserole. This is what I make Christmas morning. Today I added sauteed onions and red peppers. Absolutely delicious.
Ooh that sounds delicious to add the onions and peppers. What a fun Christmas morning tradition. So glad you enjoy the casserole!
How long does it last after cooking?
I will reheat it for a few days after.
love this type of casserole thank for posting it.
I am glad you do!! You are so welcome & thank you!
Making it again because it was a hit! They ate it for breakfast and came back for snacking later! Extra cheese made it really cheesy! For peoples who loves cheese!
Nothing wrong with extra cheese 🙂 Thank you for sharing that!
There is an error in your cheese quantity. If you get aside 1 cup of cheese (8oz), you are short 1 oz., then you are suppose to add the rest of the left over cheese when you take it out, there’s no cheese left over. Need to adjust the amount of cheese in the ingredients to 1-1/2 cups of cheese.
There’s a difference between ‘fluid’ ounces and ‘dry’ ounces when you are measuring ingredients. An 8 ounce bag of shredded cheese is 2 cups in dry ounces. It says this on the bag. It has to do with ounces actually being the weight of something, which really varies depending on what you are weighing.
I am not quite understanding how much cheese to use? It says 7 ounces but that is not even one cup but it says to reserve one cup… Can you help me out and explain? Thank you so much.
There are 8 ounce bags, that’s what I use. A little more cheese doesn’t hurt 🙂
can you use almond milk instead of skim milk or regular milk?
You sure could 😉
Can you make this in a muffin Pan?
I personally haven’t tried, but I don’t see why not 🙂 The baking time wouldn’t be as much, but I am not sure how long they would take.
Omg!!! I made this today for breakfast!! My partner & i loved it. He had 3 helpings, i had 2 lol.. Yum yum yummy!! Will definitely be making this delicious dish a lot. So easy too. Thank you so much for this recipe.
You are so welcome!! Love hearing that! Thank you!
Ive made it twice in a weeks time. I do cook my hashbrowns fIrst sInce my family likes them crispy. I heat the leftovers in a skillet so it DOESN’T get mushy.
Love that your family likes it that much! I like them crispy, too!
Could I use sage Jimmy Dean sausage and cook before adding it to the casserole?
Yes, that works too!
Not really sure what went wrong as my my eggs never cooked. I followed the directions to a t but I did find them to be a little vague.
Hmm..I am not sure what went wrong either?? They should have gotten baked. Everything just gets mixed in a bowl, minus one cup cheese, then gets poured in the pan to get baked, with the cup of cheese on top. I’m sorry!
