This Easy Egg and Potato Breakfast Casserole will transform your morning with its scrumptious and simple list of ingredients. Eggs, potatoes, and shredded cheddar cheese round out the tasty flavors, with options to personalize it using bacon, sausage, veggies, or garlic powder!
When your family could also double as a small army, meal times can get pretty hectic. With my own crew of 5, dinner’s its own chaotic harmony of “I don’t like this” or “I don’t want to eat that.” But breakfast is when the real pros come to play. If you have kiddos, you’re probably nodding your head profusely. In the morning, not only do you need to get several small bodies out the door to get to school on time, but you also have to feed them, clothe them, and make sure everyone has their homework and nobody is crying.
So, anytime I hear about a breakfast hack, I’m all the way on board. Breakfast casseroles are akin to the fairy godmother of breakfast hacks to me–they practically appear out of thin air with no time or effort, and they make all my dreams come true. This one is a real winner because it has potatoes and cheese, and you know who likes potatoes and cheese? (Most) kids. And me. And, probably, you!
This Easy Egg and Potato Breakfast Casserole is an absolute cinch to make, and you can customize it to your family’s preferences. Toss in some bacon or ham for added protein, or a bit of chopped spinach and bell peppers for color.

How do you make breakfast casserole?
Most breakfast casseroles, and casseroles in general, are super easy to make. That’s what makes them so amazing! For this one, you butter a baking dish and add chopped potatoes to it before pouring in your egg, milk, salt, and pepper mixture. Top it off with shredded cheese, and pop it in the oven for about a half hour! Bibbidi bobbidi boo–you’ve got yourself a simple-as-can-be breakfast. (I like mine topped with salsa!)
What’s the best way to reheat Easy Egg and Potato Breakfast Casserole?
Reheat your casserole in the oven to avoid it getting a weird, hardened texture from the microwave. (Bleh.) When you’re ready to serve it, pop it into a preheated 375-degree oven for about 15 to 20 minutes, until it’s heated all the way through.
Can you freeze breakfast casserole?
You sure can! It may help to freeze it in individual servings, so reheating it is simplified. Baked or unbaked, breakfast casserole can keep in the freezer for up to 2 months. Covered in the fridge, breakfast casserole will keep for 3 to 4 days.
What should you do if your breakfast casserole is too runny?
If your casserole is still runny after it has baked for 30 to 35 minutes, it’s not done cooking quite yet. Everyone’e oven is a little different, and your location’s altitude can actually affect cooking time, too! Try covering the casserole with foil (carefully, so you don’t burn yourself). Foil will allow the edges to not burn or overcook, while also trapping in the heat to finish cooking those runny parts. Another 5 to 10 minutes with a foil cover should do the trick!
Easy Egg and Potato Breakfast Casserole
Ingredients
- 6 ounces Potatoes O’Brien, half of a 12-ounce bag, about 1 1/2 cups, thawed
- 8 eggs
- 1/3 cup milk
- 1/2 teaspoon salt
- 1/4 teaspoon pepper
- 1 cup cheddar cheese, shredded
Instructions
- Preheat the oven to 350 degrees F. Butter the bottom and sides of an 8×8 baking dish.
- Pour the thawed potatoes into the buttered dish.
- In a medium bowl, whisk together the eggs, milk, salt, and pepper.
- Pour the egg mixture over the potatoes. Sprinkle the cheese evenly over the top of the casserole.
- Bake, uncovered, for 30-35 minutes, until the center is set.
- Allow the dish to cool for 10 minutes before serving.
Notes
- This is a great recipe to add things to and make it your own. Add cooked bacon, sausage, or ham to the dish before the cheese for a meatier meal. Add cooked chopped spinach to the egg mixture for more veggies and color. Add more cheese, or part cheddar and part pepper jack, to the top. This is really the bare-bones recipe that is just begging for you to add whatever you have in the fridge. A little garlic powder and green onions in the egg mixture really spruce things up, too.
- I just leave the potatoes on the counter for the afternoon to thaw them. I’m sure the microwave would work, too. I’ve tried it with frozen potatoes and the texture is not as pleasing.

Eggs are so great aren’t they? And now that it’s spring again, the hens are producing eggs like crazy. The Long Winter is over, and I couldn’t be more excited!

Have you ever made this the night before and heated it up the next morning? My husband leaves VERY early for work and I usually don’t get up to make him breakfast but maybe if I made it w dinner he could just heat it up for himself in the morning. Would that be ok or would it be soggy and gross?
It heats up great! I love making a double batch and keeping half for breakfasts later in the week. Your hubby is going to love you 🙂
If I’m using fresh potatoes about how many should I use?
What is layered first in the bottom of the pan? The potatoes or eggs. Thanks!
It doesn’t matter, it all gets mushed together! Enjoy!
have you tried this in a 13 x 9 casserole dish? do you have the adjustments? I need to make this for a baby blessing this sunday. but need to feed more than your recipe. just thought I’d ask if you’ve made this in a larger quantity. thank you!
I make it all of the time in a 9×13 dish, so you are good to go. Just double it all and it takes a bit longer to bake. And I’m blessing MY baby this weekend 🙂 Maybe we should have this! Great idea…
What can I do in place of potatoes O’Brien? Not sure we have those here ( small town in BC) Would it be hash browns?
Hash browns for sure… but add a pit of diced onion and bell pepper if you have them. Potatoes O’Brien have them in it and that’s what makes them so easy to use. I think you’ll be lacking flavor with just the has browns. Enjoy 🙂
this taste sooooooooooooooooooooooooooooooooooooooooooooooooooooooooo delicious
This looks so good. Thank you.
I love this recipe, Thanks so much.
Can you use chopped fresh potatoes or would you have to boil them first? Thanks!
For sure boil them or saute them in a pan with a little oil and salt, I don’t think they’d cook raw.
We love to had a can of green chilies, too! Yum!
Mmm. That sounds right up my alley!
Love the colors of those eggs! Does the same chicken always lay the same color? Do you know what makes the colors?
The same chickens do lay the same color, but the color can vary a little. The brown eggs can vary a lot in color from light to quite dark and sometimes they even have speckles. The greenish eggs can be light blue to dark camo-green, but the white eggs are always white 🙂 I’ve read that you can tell what color the chicken will lay based on the breed, obviously, but also the color of their ears. LOL, isn’t that great! I think just genetics makes the colors but I’m not sure what makes them vary so much.
