    The Best Ham and Potato Casserole

    Okay, you probably know by now I've developed a bit of an obsession when it comes to casseroles. But, honestly, this one may be one of my best casserole recipes yet!

    I mean, every bite of this ham and potato casserole is just chock-full of meaty, cheesy, potatoey delicious and each bite is just as good - if not better - than the last.

    What's not to love about that?

    Plus, this ham and potato bake is also super easy to make. All you have to do is cook the creamy sauce, cover the potatoes and ham with it, top everything with cheese, and bake it. Sounds easy right?

    Also, while your casserole is in the oven, you can focus on making some equally awesome side dishes to go with it - like these sugar snap peas and this Little Caesar's crazy bread. Or, maybe you can just sit back and relax and sip on this refreshing ranch water. Either option you go with is a win. Trust me!

    Ingredients

    The ingredient list for this cheesy ham and potato casserole couldn't be more straightforward. In fact, I'm willing to bet you already have most - if not all - of the ingredients you'll need to make it at home already!

    Anyway, here's what you'll need to make this ham and potato casserole recipe:

    • 2 tbsp. unsalted butter
    • 1 cup onion, finely diced
    • 3 tbsp. all-purpose flour
    • ½ teaspoon garlic powder
    • Salt and pepper
    • 1 ¼ cups whole milk
    • ½ cup chicken broth
    • 2 pounds russet potatoes, peeled and diced small
    • 2 ½ cups cooked ham, diced
    • 1 cup cheddar cheese, shredded
    • Fresh parsley

    Pretty simple, right?

    By the way, you can use a lot of these same ingredients to make this chicken cordon bleu casserole, this deviled ham, and this cheesy potato casserole! So you should definitely give one of those recipes - or all of them - a try next.

    Ingredient Substitutions And Modifications

    Now, I think this cheesy ham and potato casserole recipe is best served with the exact ingredients listed above. But, there is definitely some room for modifications depending on your preferences and what you have on hand.

    First off, when it comes to the ham, I usually buy pre-cooked ham for this recipe. That being said, you could easily use leftover holiday ham if you have enough to make this casserole.

    Also, for the creamy sauce, I like to use whole milk to give it more creaminess and chicken broth to give it some added flavor. With that said though, you can really use any kind of milk that you want in place of whole milk, and vegetable broth will work just as well in place of chicken broth. Also, just so you know, you can use cream of chicken soup or any condensed soup instead of milk and broth.

    Oh, and if you'd like to make the sauce even creamier, you can add a few dollops of sour cream to it. 

    Finally, for the cheese, shredded cheddar cheese is my favorite to make this ham casserole with, but you can really use any kind of cheese that you want. Shredded mozzarella cheese or even slices of swiss cheese or provolone cheese work well to make it too. In fact, the last time I made this ham and cheese casserole recipe I used provolone and it was bangin'.

    How To Make Ham And Potato Casserole

    As I said before, this cheesy potato casserole is a breeze to put together.

    Basically, you just build the sauce in a saucepan, then layer it with your leftover ham and potatoes, top the whole thing with cheese, and bake it in the oven until it's golden brown!

    Anyway, I know by now you're ready to get cooking, so let's stop wasting time and get to it!

    Step 1: Prep Work

    First, begin by preheating the oven to 350°F (180ºC) and greasing a 9×13 inch baking dish with butter.

    Then, when you've taken care of that, you can set the baking dish aside and move on to making the cream sauce.

    Step 2: Make The Sauce

    Now you'll want to take out a medium-sized saucepan and set it over medium heat. Then, add the butter to it, and then once it melts you can add in the diced onion and cook 'em for a few minutes until they become soft and translucent.

    Once the onion is looking good you'll want to sprinkle the flour, garlic, salt, and pepper over them and then stir everything together until combined. Then, after you've mixed everything up, you can add the milk and chicken stock and continue cooking everything on medium heat until your sauce is fully warmed through and has thickened slightly.

    Step 3: Prepare The Casserole

    While your sauce is thickening, you can spread the peeled and diced russet potatoes (or Yukon gold potatoes) evenly on the bottom of the prepared baking dish.

    Then, you can top the potatoes with some cubed ham and follow that up by evenly pouring the sauce over both the ham and potatoes. By the way, if it doesn't look even, you can spread everything out with a spatula so that it does.

    Step 4: Bake The Casserole

    So, now that your ham and potatoes casserole is all prepped you can cover the baking dish with aluminum foil and bake it for about 40-45 minutes.

    Then, when the time is up, you can remove the aluminum foil and top the casserole with the shredded cheese. Bake the dish uncovered for an additional 10-15 minutes, or until the cheese is completely melted and the potatoes are fork-tender.

    Finally, take the potato and ham casserole out of the oven, garnish it with fresh parsley, serve warm, and enjoy!

    How To Store Ham And Potato Casserole

    This recipe for ham and potato casserole makes about 4 large servings or about 6 side dish servings.

    That being said, it's so good that you should expect everyone will come back for seconds - so you might want to double, or triple the recipe when you make it.

    Then, if you end up with some leftovers of this ham and potato casserole you can store them for later. To store, just cover the casserole dish with a lid - or transfer your leftovers to an airtight container - and store them in the fridge for about 3-4 days.

    Also, if you want your leftovers to last even longer, you can freeze your casserole in an airtight container - or freezer safe bag - for up to 4 months.

    How To Reheat Ham And Potato Casserole

    When you're ready to enjoy this delicious ham and cheese casserole again, you'll definitely want to enjoy it hot.

    To reheat the leftovers, I recommend putting them back in the oven. Simply place the casserole dish, uncovered, in the oven set to 300°F for about 10-12 minutes, or until it's fully reheated.

    Alternatively, if you want to reheat just one serving, you can microwave your leftover ham and potato casserole in 30-second increments or until it's fully warmed. I find about 2 minutes usually does the trick.

      I used a 30-ounce package of Simply Potatoes (already shredded hash browns, found in most grocery stores & Walmart) The .recipe turned out great! For the cheese, I used mostly shredded pepper jack & this gave the casserole a little kick! I mixed this cheese with some shredded Cheddar. Also made some biscuits instead of toast as t to go with the casserole dish. It a as a great breakfast/lunch (brunch) meal together with the orange juice, sliced fruit, coffee or tea.
