What makes this hash brown casserole easy?

Seriously, it took me longer to preheat my oven than it did for me to prepare this egg casserole.  I used frozen hash browns, shredded cheese, and cubed ham.  So, the only real prep work that I had to do was crack open the eggs.

This casserole will feed a crowd.  It makes 12 portions.

It would be perfect around the holidays since you only need to spend about 5 minutes in the kitchen putting it together.  Then, just let it bake.

    We have been making something similar every Christmas morning for years. We use cream of mushroom soup instead of milk. The liquid firms up when you let it sit for 15 minutes before serving. We usually use tater tots instead of hash browns. 2 square pans instead of one 9×13 might bake quicker?

    This was a hit at work. I changed it up a bit and it turned out perfect! I wanted to separate it into two (2) 8×8 pans and i baked both glass pans on the center rack at 375 for 1 hour!

  3. I also add some onion to mine. But the best way to make this is in a crock pot! Turn on high for 8-10 hours. Wake up to the smell of breakfast…yum.

  4. I love this receip however, every time I make it, the middle isn’t done. Does anyone have any suggestions as to what I can do to fix this issue? I’ve adjusted the time. Cooked longer (but then it’s dry). I just need suggestions please. Thanks

    1. Are you cooking this in a deep dish? Maybe try using a larger but more shallow dish? I don’t really know, but thought this might help. Also, start with thawed hash browns and maybe crisp them up in a fry pan first.

      Use a larger pan so it won’t be so thick or 2 medium pans and cook half way throu and freeze one, and finish cooking the other one in the morning you are going to serve it!

  5. I’m going to use real potatoes and brown them like someone else did in the comments, use bacon and sausage, Mrs Dash seasoning,milk and cheese and of course eggs. I’m making it tonight to take to a friends house for breakfast for Thanksgiving morning.

    I’d actually recommend baking this at 400 instead of 350. It took me 2 hours to get the middle to set completely. Otherwise it was great! I also added chopped green peppers, crushed garlic,and bacon pieces for a little extra flavor.

  7. Delicious! I did use real potatoes-grated them- removed liquid-browned them up in cast iron skillet-10 minutes-put in baking dish-rest of ingredients on top. Perfectly done in one hour! I used canned milk. Yum!

  8. I added red, orange and green peppers as well sliced mushrooms. I mixed all of that with the hash browns did cheese then topped it with the eggs. I baked it last night for 45 minutes then put it in the refrigerator. I got it out this morning and put it in the oven to bake the rest the way. It looked mostly cooked last night. I also used refrigerated hashbrowns which was only a 20 ounce bag.

    1. I let the eggs come to room temperature. I used frozen O’brian potatoes instead of hash browns and I thawed them out in the microwave. That way everything will came to heat faster

      1. Did it take a hour then with the modifications? I have done it before and it has always been longer but am under a time constraint

    I just made this for some out of town guest, but I put pork sausage instead of ham. They loved it!!
    I made everything last night, including eggs, milk, salt and pepper in a bowl, put in refrig. Pork sausage in a separate bowl put in refrig. So this morning put hash browns in bottom of dish, then sausage, then cheese and then topped with egg mixture. So easy so good.

        1. You just made my day!! I have a group of 6 friends tomorrow for breakfast and this dish is what I wanted. Love this version with the sausages. Thank you so much.

  10. If I cut the recipe in half (6 servings) and cook it in an 8×8 glass dish, will it still need to cook for a full hour?
