What type of potatoes should you use for a potato casserole recipe
Russet potatoes work the best in this type of casserole. They have a high starch content which means they will hold their shape and not get mushy while baking. You can use other types, but the texture will be different, still delicious though.
Russets are also the potato of choice for baked mashed potato casserole, hamburger potato casserole and for au gratin potatoes for the same reason, you want the texture a russet will provide to your casserole.

Simple Ingredients for a potato casserole with ham
Cooked ham – you’ll need about 1 ½ cups diced ham. If you don’t have any left over, then use ham steaks or have them cut it at the deli. A honey baked ham works great in this dish.
Russet potatoes – 2 medium potatoes (yes the plain old kind!), peeled and diced.
Onion– I prefer a sweet vidalia onion for a milder flavor in this breakfast casserole.
Colby cheese – I like the mild flavor of this cheese but you can substitute sharp cheddar cheese instead.
Pantry staples – milk, butter, flour, salt and black pepper
Pro tip: If you are making this in advance and don’t want the potatoes to turn brown, place them in a bowl of cold water until you’re ready to assemble! Just dry them off before placing them in the casserole.
Putting together a ham and potato casserole
Step 1: chop
Peel and dice the potatoes and cut the ham into similar sized cubes. Combine the ham and potatoes in a large bowl.
Step 2: make the sauce
Saute onions in some butter in a skillet, once softened add flour and whisk together then gradually add milk whisking until it has slightly thickened. It should be pourable, if not add more milk. Salt and pepper to taste.
Step 3: make it cheesy
Add a cup of cheese to the sauce and stir until melted. Pour over the ham and potatoes. Stir until coated and place a casserole dish. (you can cover the entire casserole in plastic wrap at this point and keep it refrigerated overnight and serve the next day)
Step 4: bake
Cover with aluminum foil and bake for 40 minutes or until the potatoes are soft and the sauce is bubbly. Remove and add additional cheese. Place under the broiler for 2 minutes until the cheese melts and starts to brown.
Serve it with berries on the side or buttermilk biscuits and homemade strawberry jam. A spinach salad would be a nice addition if serving for brunch or dinner.
