Cheesy Potato Casserole
We LOVE breakfast at our house. I’m not joking when I say that we have breakfast for dinner at least ONCE a week.
We love Pancakes and Waffles, Cinnamon Rolls, Smoothies, and especially Breakfast Casseroles, like today’s Cheesy Potato Casserole.
Casseroles are so great, mostly because they’re quick, simple, and delicious. Plus, they are easy to change up based on the ingredients you love and crave most.
This particular Cheesy Breakfast Potato Casserole has potatoes, eggs, sausage, and cheese – some of our favorite breakfast or brunch ingredients. The best part of all was that it took just minutes to make!
How to Make It
The ingredients for this Egg and Potato Casserole are simple – eggs, milk, sausage, hash browns, cheese, salt, and pepper.
PREP. Preheat the oven to 350°F. Spray a 9-x-13-inch baking dish with cooking spray. Divide the cheese and set ½ cup aside.
COMBINE. In a large bowl, mix eggs, milk, hash browns, sausage, salt, pepper, and 1 cup of cheese until combined. Pour into the prepared baking dish.
BAKE. Bake for 32–35 minutes. Remove from the oven and add the remaining ½ cup cheese over the top. Place it back in the oven and bake for an additional 3–5 minutes.
There are so many easy ways to change up this recipe. Here are some try:
- Mexican: add chopped peppers and use Mexican blend cheese instead of cheddar.
- Meat lovers: add cooked bacon along with the sausage.
- Low-fat version: omit the meat and add a cup of chopped spinach and other vegetables such as zucchini, red bell pepper, or broccoli florets.
- Garnish: garnish with fresh herbs and spices like parsley and green onions. Serve with a dollop of sour cream.
Shredded hash browns. Cook times should be the same. Just like the cubed hash browns, thaw shredded hash browns for best results. If not thawed, it may need an additional few minutes to cook.
Use fresh potatoes. Peel and dice 20 oz of fresh potatoes, like russets, to use in this recipe. Don’t soak the potatoes because you want the starch from the potatoes to help thicken the Breakfast Potato Casserole as it bakes.
Sausage. Brown your own Italian Sausage in a large skillet over medium heat. Drain excess fat before using it in the recipe.
Cheese. Substitute the cheddar cheese, or combine it, with other favorites like Swiss cheese, pepper jack cheese, or Colby Cheese.
Making Ahead and Storing
STORE leftovers in an airtight container in the refrigerator for 3-4 days.
FREEZE leftovers in the freezer for later. Reheat in the microwave or oven if you have a large amount.
Make ahead of time. Make this Cheesy Potato Breakfast Casserole up to 24 hours in advance – perfect for Christmas morning!
- Cover and keep it in the fridge until ready to make. A few minutes may need to be added to the cooking time.
- Freeze it, uncooked, for up to 2 months. Wrap the pan tightly with plastic wrap and again with foil. Thaw in the fridge before baking.
You definitely can! Peel and dice 20 oz of fresh russet potatoes to use instead of the frozen kind. Don’t soak them, because the starch from the potatoes will thicken the casserole as it bakes.
You can use the precooked sausage crumbles you find in the freezer section of the grocery store, or you can use uncooked sausage. Simply brown the sausage in a skillet and drain excess fat before incorporating into the breakfast casserole.
Of course! One of the best features of this casserole is that it can be made up to 24 hours before baking. See the details above in the section titled, “Making Ahead and Storing”.

This is a favorite at our house. It’s so easy and so tasty! We actually enjoy it so much that we sometimes have it for dinner!
Need to fix your cheese measurements. Only 7oz in the whole recipe? Confused.
Yes, you’ll use about 1 cup of cheese in the casserole and the rest (about 1 cup) will go on the top. If you like more or less, you can certainly adjust the amount of cheese used.
Easy and the ENTIRE famil loved it!
Yay!! Happy they did 🙂 Thank you for trying it!
I will be making this for a homeless shelter to serve 75 people. Im going to ×6 the recipe and cook it in 2 separate large baking dishes, so recipe ×3 in each fish. How much time do you think it will take to cook each pan? Any other tips?
I would probably double it & put in an 11×17, so have 3 pans. It might need close to 40-45 min. I would start checking at 35 min, then add a couple min at a time.
I was just wondering what you mean by hash browns cubed and thawed? do you have a certain brand you use for that? sorry, just barely trying to learn how to cook. Thank you!
Any brand would work. I use Ore-Ida a lot, the southern style cubed potatoes. And, they are in the frozen section 🙂
Question, can prepare this recipe the niGht Before i bake it?
You sure could 🙂 Just cover well. Enjoy!!
I’m not a great cook, but this one turned out great when I took it to Bible study!
I love hearing that! I hope it was a hit! Thank you!
For the precooked Italian sausage, is it sold precooked in the freezer section or do I buy the Italian sausage in the meat section and cook before using?
It is sold precooked or you can cook some up. Whichever is easier for you 🙂 Enjoy!!
I made it this morning for my son & hubby. I made some changes, only to be more appealing to my son. I used tater tots, instead of hashbrowns & diced ham instead of sausage. It turned out incredible & they loved it. This is a great recipe that can totally be altered to fit your tastes. Hubby asked me to make one with bacon, sausage, peppers & onions, in the future. We also added a dollop of sour cream on top for some extra yum!
Yes, it’s great for adding what you like or taking out what you don’t. Thank you for sharing what you did!!
tHIS WAS AN EASY AND DELICIOUS CASSEROLE. tHE ONLY THING i CHANGED WAS i ADDED SOME CHOPPED GREEN ONIONS. iT WAS AMAZING. tHANK YOU FOR THE RECIPE.
Perfect!! You are so welcome! Thank you for trying it & for letting me know!
Can you dice up whole Potatoes and USe THose? Should YOu cook the whole potaties FIRSTif YOu go That route to SOften THEM or will they COOk in the Casserole ANd SOften THat way…
I am wondering the same thing. I’m bummed this is the only comment without a reply from her.
I have not tried using cubed potatoes, so I couldn’t say for sure if you would add them raw or cooked. I am thinking if they are small, they would cook in the casserole.
Made this tonight, and I used diced raw potato. It turned out great. Make sure your dices are small and cook 5 to 10 extra minutes.
Perfect!! Thank you for sharing that 🙂
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!
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!
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!
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.
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 😉
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.
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!
love this type of casserole thank for posting it.
I am glad you do!! You are so welcome & thank you!
How long does it last after cooking?
I will reheat it for a few days after.
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!
I loved this recipe! It was so easy, and so delicious. It has to perfect ratio of sausage to egg to potato.
We loved this! So easy and so filling. Perfect for Christmas morning.
This is my families favorite breakfast dishes. FABULOUS!!!!!!
Delicious cheesy goodness! This will be a go to!
Delicious! I’ve tried a few variations of this recipe over the years and this is my favorite. I love it for its simplicity and deliciousness. We just ate it for Christmas breakfast and everyone loved it. The amount was perfect for a family of 4 and we even have some leftovers.
Printing the recipe right now so I won’t forget where I got from 🙂
This looks amazing!!! Is it gluten free by chance? My new daughter in law cannot eat gluten. 😊🤞
The recipe was not created as a gluten-free recipe, but you could certainly tweak anything in it that she couldn’t eat to make it work for her. 🙂
How can I use real potatoes instead of frozen?
Yes, absolutely! Just make sure they are pre-cooked. Leftover baked potatoes are a great option if not using the frozen hash browns.
Delicious! I made it the night before and added some diced red and green pepper pieces for color.
Thanks for sharing what you did. I bet it looked and tasted great with those additions!
Only 7oz of cheese? Is the recipe correct on that? It calls for starting with 1 cup (8oz), and reserving the rest for topping.
Thanks for catching that. We’ll get that post updated!
Cant do recipe for all the ads popping up
Is that enough milk
I made this for dinner last night and everyone ages 7 to 72 loved it. I will certainly be making this a lot!! I threw a cup of shredded cheese in the casserole and another on top to melt at the end.
Can you make this ahead and freeze it?
Yes, you could!
Guessing on amount of salt makes this either over salted or under unless somehow you get lucky.
The dish was very flat and lacked flavor.
The good – this recipe was a cinch to prepare and toss in oven. The bad – hardly any flavour and too dry, tripled the cheese and it still was just cheesy.
This recipe has a decent foundation but really requires a lot of doctoring before id consider making it again.
I have always added a smidgen of cream cheese to my scrambled eggs for extra flavor and fluff. I did so here and I loved it. It’s just me so I cut the recipe down a bit, but still had enough for leftovers.
I’m making this for Easter bruch!
This is actually one of my favourite casseroles, that I make for my family on the weekends…always a HUGE hit and rarely any leftovers. I usually have to fight someone for that last piece lol! Great flavour, filling and not difficult to make!
Haha..love to hear that!! You may have to start doubling the batch 🙂 It’s great leftovers!!
I love casserole dishes for any meal. This dish is pretty good and covers all your breakfast items. Yummy!
Added cooked bacon as recommended and loved how it turned out.
Made this for Easter brunch. It was definitely a hit!
So I am having a large brunch (70 people) and wondered about double batches in larger foil pans? Any advice on baking times?
