Ingredients for Ham & Potato Casserole

Ham – You can use pre-cooked or leftover ham, or even sausage links or bacon bits.

Potatoes – Cut the potatoes into bite sized pieces or use a half potato & half sweet potato blend. Even hashbrowns will work.

Vegetables – Sweet peas are a classic addition, but you can use other veggies too. Try green beans, carrots, or diced tomatoes. Fresh broccoli, cauliflower, or zucchini also work great.

Cheese Sauce – The sauce is delicious with butter, chicken broth, and whole milk. I love ham with cheddar cheese but Monterey jack, or a Mexican cheese blend work well too. If you prefer, heavy cream can replace the milk, or you can use a can of cream of mushroom soup instead.

How to Make Ham & Potato Casserole

  1. Make the sauce with broth and milk. Once thickened, stir in cheese.
  2. Layer ½ the potatoes, ham and peas in a casserole dish. Repeat the layers and pour the cheese sauce over the top.
  3. Bake (per recipe below) until potatoes are tender, top with more cheese, and baked until the cheese is lightly browned.
  4. Let the casserole set for about 5 minutes before serving. Garnish with sour cream, salsa, or ketchup, if desired.

What Goes with Ham & Potato Casserole?

All the meat, veggies, and starch are in this delish one-dish, so serve a simple salad like this bright and tangy beet salad, or a classic wedge salad. For breakfast, add a side of fluffy scrambled eggs, and homemade biscuits.

  1. Threw this together last minute. I doubled the recipe to feed a crowd. They practically licked the pan! This is a keeper for sure5 stars

  2. Flavor is great, HOWEVER, potatoes should be boiled in advance to soften them and then place in casserole. And mix sauce throughout casserole and not just put on top.

    With raw potatoes, I had to bake the casserole for 2 HOURS to get the potatoes soft enough to be passable. After cooling, I mixed everything up in the pan and then placed the cheese on top. That ensured enough flavor throughout the casserole.5 stars

    1. OMG why did I not see the comment sooner !!! I do not have 2 hours to bake and wait …. Holly please add that to the direction to BOIL the potatoes first :(

      1. This does not take 2 hours to bake, I’ve made it countless times as have other readers. The baking time is correct as listed in step 5 and no boiling is needed.

  3. I made this recipe for dinner tonight and we love it!!! I had leftover spiral ham and followed the instructions…..presto! Very inexpensive and easy to make. This one makes it to the recipe box and shared!5 stars
