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.

    Really good! I improvised a bit, adding a layer of defrosted frozen spinach, chopped onions and mushrooms on top of the hash browns. Also added a cup of sour cream along with the milk and eggs, resulting in a very moist casserole. Holds its shape nicely when slicing and serving.

      This recipe is awesome! I used OreIda frozen hash browns, half of a yellow onion, frozen chopped spinac thawed and drained well, cheddar, and then placed slices of prosciutto on top. It’s so good!

    Love this dish! It has become a Christmas tradition to us. The recipe is delicious as-is, but I use a 30 oz bag of Potatoes O’Brien (the red and green pepper and onion provide color and flavor). I also sprinkle the potatoes, ham and cheese liberally with ground mustard before tossing them (it tends to clump if added to the eggs). And, I add 1/8 teaspoon cayenne pepper to the eggs. Reading the comments, I am eager to try using a combination of milk and sour cream. Thank you for this recipe!

    Made this for holiday department meeting at school and it was raved about. I’m emailing recipe out to the whole department to share with their friends and families. The only thing I did differently was thaw hash browns and then attempted to brown a bit in skillet but didn’t get the effect I desired as far as browning, but it didn’t matter at all! I added cooked bacon and some onion powder and two extra eggs and a splash more milk. I put cheese on top too and incorporated some chives…Delicious! Salsa is a must on the side. Thank you so much for sharing this 🙂

    1. I have added green onions. Enhanced the flavor a bit. Been thinking I want to try with green pepper & white onion this weekend.

    2. Yes adding green onion adds a great taste to ity. My family are meat lovers a actually add Jimmy Dean sausage with the ham and I go the extra mile buy cooking bacon and crumbling it on top. I jyst loved this meal especially since I can prepare it on the night before. Pop it in the oven jump in the shower and start my day!

    3. I made it with green onions and chopped green bell peppers. I sautéd the onions and peppers before adding them to the mixture but you wouldn’t have to. It added good flavor (and some good veggies).

    I made this for a church Christmas Party and everyone loved it…. most importantly, all four of my kids loved it, which is a huge win! This recipe was super easy and it came out of the pan without sticking, unlike other recipes I’ve tried. This is definitely a keeper and I can tell already it will be a family favorite. Thank you so much!

  5. I’m wondering if this can be frozen before I bake it? I am having a baby soon and I wanted to make this for Christmas breakfast but I don’t know if I’ll be up to prepping it the day before.

  6. Fabulous! Made the night before and popped in the oven for an easy Thanksgiving breakfast. Leftovers to be frozen for Mom to eat as individual meals later.

    I made 2 of these for a post-wedding breakfast and they were huge hit. I added mushrooms and subbed bacon for ham. Spice-wise, adjust for your taste. I added onion and garlic powder for more flavor. The cook time was spot on.

  8. If making this right after prepping it bakes for nearly two hours. It’s also a little heavy on the potatoes. I recommend cutting the potatoes to 6 cups and definitely letting it set in the fridge overnight.

  9. 4 stars
    Overall this is pretty good! I assembled mine the night before and put it in the fridge. I thawed the potatoes out first, added some garlic powder, ended up increasing the temp to 375 halfway through, and cooking it for about 1hr 20min. Could probably cook at at 375 the whole time to make sure the center cooks in time. I think it could use some personalization depending on your tastes. More spices, veggies, different meat, different cheeses, etc. It could be really fantastic depending on how you change it! Enjoy!
