Ingredients You’ll Need

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

Here’s everything you’ll need to make this delicious Crockpot casserole:

4 cups potatoes, diced (about 4 medium potatoes)
Yukon golds or russets work best. Peel or leave the skins on—it’s up to you.
2 cups cooked ham, diced
Use leftover ham, or pick up a pre-cooked ham steak from the store.
1 cup shredded cheddar cheese
Sharp cheddar melts beautifully and adds bold flavor.
1 can (10.5 oz) cream of mushroom soup
This is the base of your creamy sauce. You can use homemade or canned.
1 cup milk
Helps thin out the soup and create a rich, creamy consistency.
1 medium onion, diced
Adds a bit of sweetness and depth of flavor.
1 teaspoon garlic powder
For that warm, savory flavor in every bite.
1 teaspoon salt
Season to taste based on how salty your ham and soup are.
½ teaspoon black pepper
Adds a touch of spice and balances the creaminess.
½ teaspoon paprika (optional)
Adds a hint of smokiness and a pop of color.

Let’s Get Started

This is the kind of recipe that doesn’t require a lot of effort, but the payoff is pure comfort. Here’s how to make it:

Step 1: Prep Your Ingredients

Wash, peel (if desired), and dice your potatoes into bite-sized pieces. Dice the onion and ham if they aren’t already chopped.

Step 2: Mix the Sauce

In a medium bowl, whisk together the cream of mushroom soup, milk, garlic powder, salt, pepper, and paprika if using. This creamy mixture will coat your potatoes and create the delicious casserole base.

Step 3: Layer It in the Crockpot

Lightly grease the inside of your Crockpot. Layer half of the potatoes, half of the ham, and half of the diced onions. Pour half of the creamy sauce over the top and sprinkle with a bit of cheese. Repeat with the remaining ingredients, finishing with a layer of sauce and the rest of the shredded cheese on top.

Step 4: Cook Low and Slow

Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are fork-tender and everything is bubbly and golden around the edges.

Step 5: Serve It Up

Once it’s done, give it a gentle stir and let it sit for 5–10 minutes to thicken slightly. Serve hot, garnished with fresh parsley or green onions if desired.

Servings and Pairing

This recipe makes about 6 hearty servings, depending on portion size.

Pairing Ideas:

Fresh Green Salad: A crisp salad with vinaigrette adds a refreshing contrast.
Steamed Broccoli or Green Beans: Balances the richness of the casserole.
Crusty Bread or Rolls: Perfect for scooping up every creamy bite.
Applesauce or Pickles: A sweet or tangy side pairs beautifully with ham.

Variations

Want to switch things up? Try these fun variations on the classic:

Add Vegetables: Mix in peas, corn, or diced bell peppers for added color and nutrition.

Go Spicy: Use pepper jack cheese or add a pinch of cayenne for a little heat.
Cream of Chicken or Celery Soup: Swap the mushroom soup for a different flavor base.
Bacon Boost: Add crispy bacon bits for extra smokiness and crunch.

Storage Tips

Got leftovers? This dish stores and reheats like a dream.

Refrigerator: Store in an airtight container for up to 4 days.
Freezer: You can freeze portions for up to 2 months. Just note the texture may be slightly softer upon reheating.
Reheating: Reheat in the microwave or oven until warmed through. Add a splash of milk if it’s too thick.

Make-Ahead Tip: Prep everything the night before, store it in the fridge, then start the Crockpot in the morning.

FAQs

Can I use frozen potatoes?

Yes! Frozen diced potatoes or hash browns work well—no need to thaw, just add an extra 30–60 minutes to cooking time.

Do I have to peel the potatoes?

Not at all. Leaving the skin on adds texture and saves time. Just be sure to scrub them well.

Can I use cream of chicken soup instead?

Absolutely. It’ll change the flavor slightly but still be creamy and delicious.

Can I make it vegetarian?

Yes—skip the ham and add more veggies like mushrooms or spinach. Use vegetarian “cream of” soup if desired.

Will it overcook if I leave it on too long?

If cooked on LOW, it’s forgiving for an hour or so extra. On HIGH, try not to go past the recommended time to avoid mushy potatoes.
