Easy Egg and Potato Breakfast Casserole


Easy Egg and Potato Breakfast Casserole

  • Author: Melissa Griffiths - Bless this Mess
  • Prep Time: 10 min
  • Cook Time: 30 min
  • Total Time: 40 minutes
  • Yield: 9 servings 1x


  • 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


  1. Preheat the oven to 350 degrees F. Butter the bottom and sides of an 8×8 baking dish.
  2. Pour the thawed potatoes into the buttered dish.
  3. In a medium bowl whisk together the eggs, milk, and salt and pepper.
  4. Pour the egg mixture over the potatoes. Sprinkle the cheese evenly over the top of the casserole.
  5. Bake, uncovered, for 30-35 minutes until the center is set.
  6. Allow the dish to cool for 10 minutes before serving.


  • This is a great recipe to add things to. 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 spruces 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.

    1. 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.

      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 🙂

    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!

    1. Melissa

      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…

    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?

    Tried this today and it was really good. I used the hashbrown potatoes instead of the O’Brien ones since that was what was on hand. I sauted the onions first then cooked the hashbrowns in a skillet prior to adding them to the dish. You really can make this dish into whatever floats your boat. Great recipe!

    Just a quick note you might want to amend “pour the eggs over the eggs”, I assume you meant pour eggs over potatoes? Looks like a great recipe, I never have time to make decent breakfast before work so I’m going to try to make this on a Sunday to last a few weekday mornings 🙂

    Thank you for the encouragement- sure needed it today! We have 19 chickens and I cook for a family of 8 big eaters most meals. Eggs are a staple for us. Since you mentioned eating eggs for other meals, and like to keep down the unhealthy carbs, I want to make sure you know something I just recently figured out— you don’t need a crust for quiche recipes! I make all kinds for all meals, adding leftovers if they sound good. I just whisk into to egg mixture a couple spoonfuls of gluten free flour mix. Sometimes, if making a Mexican style quiche, I sprinkle a little cornmeal in my greased quiche pan. 🙂

  8. This was very good. I’ve made this twice. I’d recommend to use a bigger dish. Mine takes an hour to cook the egg fully. But overall very good. Thank you for sharing.

    I made this using real potatoes and it seemed to turn out great! I just grated raw potatoes, pressed them in a towel to get rid of excess moisture, and browned them in a pan with olive oil and green onions before adding them to the baking dish. Loved this recipe and how simple it was to get a good, full breakfast on the table!

    What do you consider a serving size? I am sorry I know that is probably an odd question but We are “new” to clean eating and I have an 18 & 21 year old who eat me out of house and home. My husband’s job is also very labor intensive and generally eats about 3000 cals a day to give you an idea (and he’s not obese)

  11. […] This is one of my very favorite tricks to eating a powerhouse of a breakfast without too much time or effort. I hope it helps and that you love it as much as I do. Long live omelets in a jar!

    Easy and tastes great. I love to vary a recipe! For variety I have used pico de gallo (drained well) in place of bell pepper. For garnish I used a dollop of light sour cream. I have also used left over baked potatoes cut into cubes with chopped onion in place of frozen mix.
    For Easter i will use this and add cooked asparagus and diced ham. I will probably have to add to cooking time.

    1. Melissa

      Yep, works great! Just make it and keep it in the fridge until you are ready to bake, you might need 5 extra minutes in the oven to account for it being cold, but you won’t need to change anything else!
