    Mashed Potato and Ham Casserole Recipe

    Underground Ham Casserole is an Amish ham and mashed potatoes casserole that is great to serve as a main dish.

    It's simply cubed ham and mushroom gravy topped with delicious mashed potatoes. And this diced ham casserole is an easy-to-make and hearty dish that will be loved by all!

    Underground Ham Casserole

    It's apparent where the name "Underground ham casserole" came from because the ham and gravy are buried beneath the mashed potatoes. You have to dig underground to find the ham. 🙂

    And if you ever browse through an Amish or Mennonite cookbook, you might find interesting names for some of the recipes. I guess someone got bored with common recipe names, so they decided to get creative.

    But the name for this potato ham casserole totally makes sense.

    Leftover Ham and Mashed Potatoes

    This mashed potato and ham casserole recipe is a great way to use up leftovers.

    Perhaps you've cooked a big Christmas or Easter dinner and ended up with lots of leftover mashed potatoes and ham. Here's a delicious way to use both of them.

    It's ok to use leftover mashed potatoes even if they aren't made the same as in this recipe. If they seem really stiff, you can warm the potatoes and mix in the sour cream. Then use them to make this delicious Amish casserole.

    How to Make Ham and Potato Casserole

    To make this easy ham and potato dish, you'll want to start by peeling and cooking the potatoes.

    Peel and slice or dice the potatoes. Place them in a large pot with several inches of water. Bring to a boil and cook for about 20 - 25 minutes until they are soft. (Continue boiling the potatoes until you are ready to mash them.)

    Drain the water and mash the potatoes (I use my hand mixer). Add the sour cream, milk, and seasonings and beat until creamy.

    While the potatoes are cooking, melt the 2 Tbsp. butter in a small skillet. Add the chopped onions and cook until softened, then add the ham and Worcestershire sauce. Pour this mixture into a roaster or deep-dish 8" baking pan.

    Mix the cream of mushroom soup, milk, and cheese in a small saucepan and heat. Then pour this mixture over the top of the ham.

    Carefully spoon the mashed potatoes over the mushroom gravy and spread them over the top.

    To make brown butter, you simply melt salted butter and continue cooking it until it is lightly browned with a wonderful nutty aroma. Drizzle this over the top of the mashed potatoes.

    Make-Ahead Ham and Mashed Potatoes Casserole

    This Amish potato casserole can be made ahead and refrigerated overnight. And you won't need to heat the mushroom soup mixture before adding it.

    However, you will need to bake it longer since it will be cold. I recommend baking this cold casserole dish at 275 degrees for an hour or until heated through.

      Hi! Whole family enjoyed this!!!

      As a #Suggestion: As a Mum, a Nutritionist, and a Chef, I have a couple of things to recommend (PLEASE don't take this as criticism!!) A. I never peel my potatoes, as all the nutrients are in the peels - and B. I always use red potatoes, since they're so gloriously waxy, and the skins so thin!! Sure, it makes a chunky "smashed" potato, but it's SO DELICIOYUS - for #5 of potatoes, I use #.5 of butter, and maybe 1/2-3/4 cup whole milk, that's all, and they're perfect!. C. ALWAYS cut potatoes 1 time, LENGTHWISE - potatoes absorb water on all cut sides, so giving it just a single side to absorb helps ensure they will never be gluey!!! D. Let the potatoes sit a bit in the colander (DO NOT rinse, you want that starch!). But it helps any excess water drain off.

      Truly, I thought I was the mashed potato master until I learned about the single lengthwise slice - it really does make all the difference!!! And leaving it as a "slightly chunk smashed potatoes" made digging through to the diced ham/gravy even more delightful - bites of potato and ham in a heavenly bechamel (I'm allergic to onions, so I omit and just make a bechamel gravy without)? Bliss!!!

    Hi, I’m Anna. I grew up Amish in the Lancaster County, Pa. area (the heart of Amish country). I currently live in a small rural town in Missouri and am a homeschool mom to 4 great kids. Some of my favorite things to do are spending time in the kitchen, (baking and preparing meals from scratch), gardening, and spending time with my lovely family.
