Cheesy Potato Casserole

MeatlessPotatoesSide Dish

     Cheesy Potato Casserole is a mix between the one my Mom used to make, and one I found on the bag of my frozen hashbrowns a few years ago. This is a perfect side dish to any beef, ham or chicken dinner. I’ve even made it for breakfast!


    This cheesy casserole is so comforting and yummy. I actually decided next time I make it, I’m going to throw in some chopped ham, and it’ll be a complete dinner in itself. I love it when you can turn a side dish into a main course with hardly any effort! With our hectic schedule, I am always trying to think of ways to make dinner time easier!

  1. All time BEST potato casserole EVER.
    I once had to come up with a Sunday school breakfast on the fly (read that “Oops! Is it my turn already?!”)so I did this casserole and just stirred in some green onions and ham pieces to make it “breakfasty”, it was DELICIOUS too!

  2. Do you think I could use this recipe in a crockpot? Best sounding one I’ve seen but I want to crockpot it so it stays warm all day.. Thanks!
