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.

    Love this recipe! I will substitute sausage with a little spice over the ham. Sometimes I also add bell peppers and a few other veggies as well. Yum!

    Prepared and baked this recipe for a brunch with my grandchildren, who are rather picky eaters. The recipe was simple with a limited number of ingredients. After being refrigerated all night, the casserole baked up very nicely. Everyone, including my grandchildren, enjoyed eating it; and my husband and I enjoyed the leftovers. Very tasty recipe just as it is. Lots of opportunity to customize the recipe with other ingredients, i.e. sweet peppers, mushrooms, onions. What I enjoyed the most was isn’t wasn’t too cheesy, or too potatoey; it was just right!

    I tried this egg recipe for a brunch when my daughter came over and she really liked the casserole. My partner also enjoyed it, I halved the recipe as we were only three and added some red peppers for colour. Yes, I will make this again, definitely a keeper.

      Yes! I use the diced hashbrowns with the peppers and onions and they work great. I also sauté additional pepper and onion and throw it in, which adds a lot of flavor!

    This was extremely easy to make and very tasty. I used the hash browns that has peppers and onions in it, so I had to add a few more eggs because the bags was 28oz. My family enjoyed it, I will be making this again.

    I make this casserole all the time. Everyone loves it. Especially with salsa. I substitute sausage for the ham sometimes. it is tasty that way too.

  6. 5 stars
    This was very good to eat. I really like the fact I just dumped it all together the night before and popped it in the oven the next morning.

    Great starter recipe! I had to use sour cream instead of milk. I used O’Brien Hash Brown’s and only had four eggs!
    I diced a whole ham steak, half an onion, green and red bell peppers! I then combined them all together with shredded Nacho cheese. Alot of yummy sounds during breakfast!

  8. 5 stars
    I added jalapeño, green onions and broccoli, also one additional egg and about 1/4 more of almond milk. I also baked for about 50 minutes and it was delicious.

    Make this recipe every Christmas morning. Make it the night before, store in the fridge, pop it in the oven before gifts and it’s done around the time gifts are! We usually make it with a mixture of bacon and sausage instead of ham!

    This was good! I changed a bit. Sautéed onions and poblano peppers seasoned with salt and pepper and smoked paprika were mixed in, along with cooked chopped bacon.

    I make this every Christmas for our family’s brunch! The only thing I do different is sprinkle cooked crumbled bacon on top! It’s everyone’s favorite!
