Crockpot Scalloped Potatoes and Ham – Easy & Creamy Comfort Food

By Callie

Introduction

I’m going to tell you the story of how this recipe became a permanent part of our dinner rotation. It was the week after Easter, and I had a huge chunk of leftover ham sitting in the fridge staring at me every time I opened the door. I’d already made ham sandwiches twice, Emily was over it, and I couldn’t bring myself to throw it away. So I peeled a bag of russet potatoes, layered everything into my slow cooker with some cheese and a quick creamy sauce, and left the house to run errands. When I walked back in three hours later, the whole kitchen smelled like the inside of a really good diner – buttery, cheesy, and warm in a way that immediately made me hungry.

That first batch of crockpot scalloped potatoes and ham was gone in one sitting. Emily had two helpings. My husband scraped the bottom of the Crockpot with a spoon. And I stood there thinking, “Why have I been making this in the oven all these years?” The slow cooker version is just as creamy, just as cheesy, and about ten times easier because you don’t have to babysit anything. You layer it, pour the sauce over, set the timer, and walk away.

Now I make these slow cooker scalloped potatoes at least once a month, and not just when we have leftover ham. I’ll grab a small ham steak from the deli counter specifically because I want this dish for dinner. It’s the kind of recipe that feels like a warm hug on a cold night – tender layers of potato soaked in a rich, cheesy sauce with salty bites of ham throughout. It’s comfort food in the truest sense, and the Crockpot makes it practically foolproof. If you love easy slow cooker comfort meals, you should also try my Crockpot Shepherd’s Pie – it’s another set-it-and-forget-it dinner that our family goes crazy for.

Why You Will Like This Crockpot Scalloped Potatoes and Ham

• Just 15 minutes of hands-on prep – Peel, slice, layer, pour, and set the timer. That’s really it. The slow cooker handles everything else while you go about your day.
• No oven required – This is a lifesaver during the holidays when your oven is occupied by a turkey or a casserole. It also keeps your kitchen cooler during warmer months since the Crockpot doesn’t heat up the whole house.
• Creamy, cheesy, and rich – The combination of cheddar cheese and cream of mushroom soup creates a sauce that coats every single potato slice. It’s thick, luscious, and honestly addictive.
• Perfect way to use leftover ham – Got a pile of ham leftover from Easter, Christmas, or a Sunday dinner? This recipe puts it to delicious use instead of letting it go to waste.
• Family-friendly and budget-friendly – These are simple, affordable ingredients that most people already have at home. Kids love it because it’s cheesy and mild, and adults love it because it tastes like something your grandma would have made.
• Great for potlucks and gatherings – You can make it right in the Crockpot and bring it to the party. It stays warm, it serves a crowd, and everyone always asks for the recipe.
• Feeds a crowd without much effort – This makes enough for 8 generous servings, and it scales up easily if you’re cooking for a bigger group.
• Leftovers are just as good the next day – If anything, the flavors get even deeper overnight as the potatoes soak up more of that creamy sauce.

Crockpot Scalloped Potatoes and Ham Ingredients

Here’s what you need for this creamy scalloped potato recipe:

• 8 medium Russet potatoes, peeled and sliced – Russet potatoes are my top choice because they hold their shape during the long cook time but still get perfectly tender inside. Yukon Gold potatoes are a great alternative if you want a slightly creamier, more buttery texture. Slice them about 1/4-inch thick – a mandoline slicer makes this fast and uniform, but a sharp knife works fine too.
• 1 sweet onion, diced – Sweet onion (like Vidalia) adds a mild, slightly sweet flavor that melts into the sauce as it cooks. Regular yellow onion works too, but it’ll have a sharper bite.
• 2 cups cooked ham, cubed – Cut the ham into bite-sized cubes, about 1/2-inch pieces. Leftover holiday ham is perfect here, but a ham steak from the deli works just as well. You want the ham pieces small enough that you get some in every scoop.
• 1 1/2 cups cheddar cheese, shredded – Shred your own cheese from a block if you can. Pre-shredded cheese has a coating on it that prevents clumping in the bag, but it also prevents it from melting as smoothly. Block cheddar melts into that silky, gooey consistency you want.
• 1 can condensed cream of mushroom soup – This is the base of the creamy sauce. It’s thick, rich, and does all the heavy lifting in terms of creating that classic scalloped potato texture.
• 2/3 cup milk – Whole milk gives you the creamiest results. Half-and-half makes it even richer if you’re feeling extra. Avoid skim milk – it can make the sauce thin and watery.
• Thyme, to taste – Dried thyme adds a warm, earthy note that pairs beautifully with potatoes, ham, and cheese. Start with about 1/2 teaspoon and adjust from there.
• Ground black pepper, to taste – A good amount of freshly cracked black pepper makes a difference. The ham is usually salty enough that you don’t need much added salt, but taste as you go.
• A few pinches of salt, for the potatoes – A light seasoning on the raw potato slices before layering helps the flavor develop from the inside out.
• Cooking spray – For greasing the Crockpot insert. This makes cleanup so much easier.
• Green onion, for garnish (optional) – A sprinkle of chopped green onion on top adds a fresh, crisp contrast to all that creamy richness.

Callie’s Kitchen Note: I tested this recipe with both cream of mushroom and cream of chicken soup, and they’re both great. Cream of mushroom gives you a slightly deeper, earthier flavor, while cream of chicken keeps it lighter and more neutral. If you have someone in the family who doesn’t like mushrooms, the cream of chicken swap is a good workaround – they won’t even notice.

How To Make Crockpot Scalloped Potatoes and Ham

Prepping the Slow Cooker and Ingredients

Start by spraying the inside of your Crockpot generously with cooking spray. Don’t skip this – potatoes and cheese love to stick, and you’ll thank yourself later when cleanup takes two minutes instead of twenty.

Peel all 8 potatoes and slice them into 1/4-inch thick rounds. Consistency matters here. If some slices are thick and some are paper-thin, they’ll cook unevenly and you’ll end up with some that are mushy and others that are still crunchy. A mandoline slicer is the fastest way to get uniform slices, but if you’re using a knife, just take your time and aim for even cuts.

Dice the sweet onion and cut the cooked ham into bite-sized cubes.

Layering the Ingredients

Toss the sliced potatoes with a few pinches of salt in a large bowl. This simple step seasons the potatoes from the inside so they’re not bland in the middle.

Now build your layers. Spread half of the potatoes across the bottom of the greased Crockpot. Top with half of the diced onion, half of the cubed ham, and half of the shredded cheddar cheese. Repeat with the remaining potatoes, onion, ham, and cheese to create a second layer.

The layering is what makes this dish work. Every bite gets a little potato, a little ham, a little cheese, and a little sauce.

Making the Creamy Sauce

In a small bowl, whisk together the cream of mushroom soup, milk, dried thyme, and a good crack of black pepper until smooth. Pour this mixture evenly over the top of the layered ingredients. It’ll seep down through the layers as it cooks, coating everything in a thick, creamy sauce.

Callie’s Kitchen Note: I made the mistake once of just dumping the condensed soup straight from the can onto the potatoes without whisking it with the milk first. The result was patches of super thick soup and patches of dry potato. Take the 30 seconds to whisk it smooth – it makes a huge difference in how evenly everything cooks and coats.

Cooking to Perfection

Put the lid on and cook:

• On HIGH: 3-4 hours
• On LOW: 6-8 hours

The low and slow method gives you a deeper, more developed flavor because the ham and onions have more time to release their juices into the sauce. But the high setting works perfectly when you need dinner faster.

How do you know it’s done? Pierce the potatoes with a fork. They should slide through easily with no resistance, but the slices shouldn’t be falling apart into mush. If they’re still firm in the center, cover and cook for another 30-45 minutes.

Garnishing and Serving

Once the potatoes are tender, sprinkle some chopped green onion over the top for a pop of color and a fresh, slightly sharp bite that cuts through the richness. Serve it straight from the Crockpot while it’s warm and bubbly.

Common Mistakes To Avoid

Slicing potatoes too thick. If your slices are thicker than 1/4 inch, the centers won’t cook through in the given time frame and you’ll bite into crunchy potato surrounded by creamy sauce. Not great. Use a mandoline or take your time with a knife to keep them even and thin.

Forgetting to grease the Crockpot. The cheese and sauce will bake onto the sides of your slow cooker insert and turn into a cement-like crust that’s miserable to clean. A quick spray of cooking spray before you start layering saves you a serious scrubbing session later.

Using pre-shredded cheese. I know it’s convenient, but the anti-caking powder on pre-shredded cheese prevents it from melting into that smooth, gooey layer you want. Spend the extra two minutes shredding from a block. The difference in the finished dish is noticeable.

Overcooking on high. If you leave it on high for more than 4 hours, the potatoes on the bottom can get mushy and the edges can start to dry out. Set a timer and check at the 3-hour mark.

Callie’s Kitchen Note: I once tried adding raw, uncooked ham to the slow cooker thinking it would cook along with everything else. It did technically cook, but the texture was totally different from using already-cooked ham. The leftover or pre-cooked ham holds its shape and gives you those nice, defined cubes throughout. Stick with cooked ham – it’s worth it.

Not letting the milk and soup come to room temperature. Pouring ice-cold sauce over the potatoes slows down the cooking process and can cause uneven results. Let the milk sit on the counter for a few minutes while you prep everything else.

Storage and Reheating

Refrigerator storage: Transfer leftover crockpot scalloped potatoes and ham to an airtight container and store in the fridge for up to 4 days. The flavors continue to develop as the potatoes soak up more sauce overnight, so next-day leftovers are honestly some of the best bites.

Can I freeze this? I don’t recommend it. Potatoes tend to become grainy and watery when frozen and thawed, especially in a creamy sauce. The texture just isn’t the same. If you do need to freeze a portion, Yukon Gold potatoes hold up slightly better than Russets, but set your expectations accordingly.

Oven reheating (best method): Transfer a portion to an oven-safe dish, cover with foil, and bake at 350 degrees F for 15-20 minutes until heated through. Add a splash of milk if the sauce has thickened too much overnight. This method keeps the potatoes tender and the cheese melty.

Microwave reheating: Heat in 30-second bursts, stirring gently between each round to avoid cold spots. Cover with a damp paper towel to keep moisture in.

Slow cooker reheating: Place leftovers back in the Crockpot on LOW for about 1 hour, stirring occasionally. Add a tablespoon or two of milk to loosen the sauce. This is my go-to method when I’m reheating a larger amount for the family.

Meal prep tip: This dish reheats really well as individual portions for weekday lunches. Scoop servings into separate containers, refrigerate, and grab one each morning. A side of steamed broccoli or a small green salad rounds it out nicely. For more guidance on safe leftover storage times, the USDA’s food safety guidelines are a good reference.

Crockpot Scalloped Potatoes and Ham Variations

Homemade Sauce Version (No Canned Soup) – If you’d rather skip the condensed soup, make a quick homemade roux. Melt 3 tablespoons of butter in a saucepan, whisk in 3 tablespoons of flour, and cook for about a minute. Slowly whisk in 1 1/2 cups of warm milk until smooth and thickened. Season with thyme, salt, pepper, and a pinch of garlic powder. This gives you a cleaner-tasting sauce with no preservatives.

Spicy Jalapen-o Version – Add 1-2 diced jalapenos to the layering process and stir a pinch of cayenne pepper into the creamy sauce. Top with sliced jalapenos and a sprinkle of pepper jack cheese instead of cheddar for a slow cooker version with real heat.

Extra Cheesy Version – Add an extra 1/2 cup of shredded cheese to each layer (so 2 1/2 cups total) and mix in 2 tablespoons of cream cheese to the sauce before pouring it over. Top with a final handful of sharp cheddar in the last 15 minutes of cooking so it melts into a gooey golden layer on top.

Broccoli Cheddar Ham Potatoes – Layer small broccoli florets in with the potatoes and ham. The broccoli steams perfectly in the slow cooker and adds color, texture, and vegetables to the dish. Emily actually eats broccoli willingly when it’s buried in cheese sauce, so this is a secret win for me.

Callie’s Kitchen Note: I tried making a “healthier” version using Greek yogurt mixed with low-fat milk instead of the condensed soup. It was fine, but it tasted more tangy than creamy and didn’t have that same rich, cozy feel. If you want to lighten it up, I’d recommend using cream of chicken soup with 2% milk instead of going the yogurt route. Still creamy, just a little lighter.

Bacon Ranch Scalloped Potatoes – Swap the ham for crumbled cooked bacon and stir a tablespoon of ranch seasoning into the creamy sauce. Top with extra bacon crumbles and a drizzle of ranch dressing after cooking. This is not health food. But it’s incredible.

Turkey Ham Version – For a lower-fat option, use turkey ham instead of regular ham. The texture is slightly different but it works well in the slow cooker, and the cheese sauce makes up for any richness you lose.

Serving Suggestions

Classic side dishes: These crockpot scalloped potatoes pair perfectly with steamed broccoli, roasted green beans, or a simple side of buttered corn. The vegetables add freshness and color next to the rich, cheesy potatoes.

Bread on the side: Warm, buttery dinner rolls or a crusty baguette are perfect for soaking up the creamy sauce at the bottom of the bowl. I always make rolls when I serve this because nobody can resist mopping up that last bit of cheese sauce.

Salad pairing: A crisp garden salad with a tangy vinaigrette provides a light counterbalance to the richness of the dish. Something with some acidity – like a lemon vinaigrette or an apple cider dressing – works especially well to cut through the cheese.

For a holiday meal: Serve alongside roasted turkey, glazed ham, or roasted chicken for a holiday-worthy spread. This dish easily replaces the traditional oven-baked scalloped potatoes and frees up your oven for the main course.

Potluck or game day: Make it in the Crockpot, bring the whole thing to the party, and plug it in on the warm setting. It stays at the perfect temperature for hours and people can serve themselves.

Beverage pairings: A glass of Chardonnay or Sauvignon Blanc complements the creamy, cheesy flavors nicely. A light lager or amber ale also pairs well if you’re more of a beer person. For something non-alcoholic, cold apple cider adds a sweet, crisp contrast, or try sparkling water with lemon to cut through the richness.
