Do you ever have that random piece of ham leftover from a holiday or Sunday dinner, and you just can’t face making sandwiches again? I know I do! That’s why I perfected this Ultimate Creamy Slow Cooker Scalloped Potatoes and Ham Casserole. This isn’t your grandma’s stovetop version that requires constant stirring—no sir! This is pure, hands-off, set-it-and-forget-it comfort food that smells amazing filling up the house.
I’ve gone through about a dozen variations over the years just to get that sauce perfectly thick and ultra-cheesy without scorching on the bottom of the slow cooker. Honestly, using the Crock Pot for scalloped potatoes and ham is a lifesaver on busy weeknights. You’ll find that after seven hours on low, those starchy Russets turn into velvety, tender layers smothered in sharp cheddar and smoky Gouda. Trust me, this hearty family dinner idea is about to become a staple on your rotation!
Why This Slow Cooker Scalloped Potatoes and Ham Casserole is Your New Family Favorite
When I tell people I skipped the oven for this rich casserole, they look nervous! But I promise, the slow cooker totally changes the game for creamy scalloped potatoes with ham. You get unbelievable tenderness without babysitting a hot oven all afternoon. The texture ends up silkier than most baked versions, honestly.
Here’s why folks keep asking me for this version:
- Maximum Creaminess: The low, slow heat lets the starch from the potatoes really melt into the milk and cheese, creating that dreamily thick sauce.
- Total Convenience: Prep takes maybe 20 minutes, and then you walk away. It’s perfect for when you need the oven free for something else—like pie!
- The Best Leftover Ham Recipe: If you have leftover ham taking up space in the fridge, this is the absolute best way to use it up and make it taste brand new again.
- Cheese Factor: We use two types of cheese here, and they blend beautifully. It hits all those deep, satisfying, cheesy potato bake cravings you might have.

Ingredients for the Ultimate Creamy Scalloped Potatoes and Ham
Gathering your ingredients for scalloped potatoes and ham is the real work here, because once they are in the slow cooker, you’re mostly done! Accuracy matters, especially how thin you get those potatoes. I swear by my mandoline slicer, but don’t panic if you don’t have one—just take your time slicing them about 1/8 inch thick. Uniform slices mean they all cook through at the same rate!

Potato and Ham Base Ingredients
This is the heart of our casserole. Make sure your ham is already cooked and diced up into nice little bite-sized chunks!
- Russet potatoes: 3 pounds, peeled and thinly sliced
- Fully cooked ham: 1 pound, diced
- Onion: 1 medium, thinly sliced
- Salt: 1 teaspoon
- Black pepper: 1/2 teaspoon
- Paprika: 1/4 teaspoon
- Butter: 2 tablespoons, cut into small pieces for dotting the top
Creamy Cheese Sauce Components
This is where the magic for that ultra-creamy texture comes from. The secret to a lump-free sauce? Whisk the flour into the cold milk *before* adding it to any heat, even though we mix it cold here!
- All-purpose flour: 2 tablespoons
- Milk (whole or 2%): 2 cups
- Shredded sharp cheddar cheese: 1 cup
- Shredded smoked Gouda cheese: 1/2 cup
How to Prepare Perfect Slow Cooker Scalloped Potatoes and Ham
Getting this scalloped potatoes and ham casserole into the slow cooker is surprisingly easy, which is why it beats standing over the stove any day! First things first, you absolutely must grease your slow cooker insert well. I use butter for this, but a quick spray of cooking oil works too. We want absolutely no sticking later when we slide that cheesy goodness out!
Before we layer, take a moment to mix that sauce. In whatever bowl you used for your shredded cheese, whisk the flour right into the cold milk until it looks completely smooth—no dry pockets of powder allowed! Then toss in both the cheddar and Gouda. This careful pre-mixing step is vital for getting a thick, flavorful sauce later on. If you want an extra boost of cheesy depth, check out my guide on other methods for making cheesy scalloped potatoes!
Layering the Scalloped Potatoes and Ham Casserole
This is the fun part—building the layers! Divide everything in half. Start by spreading half of your thinly sliced potatoes in an even bed right on the bottom. Then sprinkle over half of the ham, the sliced onions, and half of your seasonings (salt, pepper, paprika). Remember, we are aiming for even distribution!
Now, pour half of that beautiful, creamy cheese sauce right over that first layer. Don’t worry if it doesn’t spread perfectly; it will settle as it cooks. Repeat everything: remaining potatoes, then the rest of the ham, onions, and spices. Finally, pour that last bit of sauce over the top layer. The very last thing you do before putting the lid on is dot the surface evenly with those small, cute pieces of butter. Those little spots melt down and help keep the top layer from drying out during the long cook time.
Slow Cooker Cooking Times and Doneness Check
Time to seal it up and let the magic happen! You have two options here, depending on when you need dinner. If you started this in the morning, cook it on LOW for about 6 to 7 hours total. If you’re rushing in the late afternoon, setting it on HIGH will work in about 3 to 3.5 hours. Either way, the best test isn’t the clock, it’s the fork!
When the time is up, pierce the thickest part of the casserole with a dinner fork or the tip of a sharp knife. If it slides in with zero resistance—meaning the potatoes are totally soft—it’s done! If you feel any hardness, just put the lid back on for another 30 minutes and check again. Once it’s perfectly tender, take the lid off and let it just sit there for about 10 minutes before you serve it straight from the slow cooker. It needs that little rest to firm up the sauce just a bit!
Tips for Success with Creamy Scalloped Potatoes and Ham
I’ve made this glorious scalloped potatoes and ham dish so many times now that I feel like it just cooks itself, but there are a few little tricks I learned the hard way that I absolutely have to share with you. Get these steps right, and you’ll never have a crumbly or undercooked bite!
First off, let’s talk potato slicing again. Three pounds of Russets sounds like a lot, but it really isn’t once they are sliced thin. If you don’t have one of those nifty mandoline slicers, just take your time with a sharp knife, aiming for that 1/8-inch thickness. Seriously, this is non-negotiable for even cooking in the slow cooker. If some slices are fat and some are whisper-thin, you’re asking for half mushy potatoes and half crunchy ones!
Also, don’t skimp on the cheese change-up! While extra cheddar is always nice, that little bit of smoked Gouda is what gives this easy ham and potato casserole that restaurant-quality savoriness. If you absolutely can’t find Gouda, just use more sharp cheddar, but maybe add just a tiny pinch of smoked paprika to the sauce mixture next time to try and mimic that flavor—it helps!
Now for my absolute biggest, secret weapon tip for the slow cooker: hot spots! Some slow cookers run hotter on the bottom than others, and on a long cook like this, even gentle heat can scorch the liquid right near the ceramic bottom. What I do now? I take a few small, heat-safe ceramic coasters or even a tiny metal rack—ensure whatever you use is oven-safe—and I place that right on the bottom of the insert *before* I start layering the food. It creates a tiny air barrier that gently diffuses the direct heat. Trust me on this one; it saves your sauce from that slightly burned taste!

Making Ahead and Storing Your Scalloped Potatoes and Ham
I know that cooking a big casserole sometimes means planning is essential, especially if you’re using this for a holiday meal or a large family gathering. The beauty of this slow cooker scalloped potatoes and ham recipe is that you can definitely do some prep ahead of time to save yourself time on the actual serving day!
Prep Work You Can Do Early
If you want to get the chopping out of the way the night before, go for it! The trickiest part is the potatoes. You can slice all three pounds of those Russets and store them right away. Just put them into a big bowl, cover them completely with cold water, and stick the bowl right in the fridge. The water keeps them from browning—that oxidation process is a pain! They’ll be just fine submerged for up to 24 hours.
You can also dice up all your ham and slice your onion ahead of time. Store them in separate, airtight containers. When you go to assemble the casserole the next day, just drain those potatoes really, really well before you start layering!
Assembling the Casserole Unbaked
You can actually assemble the entire easy ham and potato casserole right up until the point you would turn the slow cooker on. Grease the insert, layer everything—potatoes, ham, sauce—just like we discussed. But instead of turning it on, cover the slow cooker tightly with its lid, wrap the whole thing in plastic wrap, and refrigerate it overnight. This is perfect because you only need to add that final dotting of butter on top before you switch it to cook on LOW for maybe 7.5 to 8 hours, since it’s starting cold.
If you’re prepping components for a big brunch, you might want some tips on making things ahead for those events. I have a great guide for Make Ahead Cheesy Egg Cups that follows a similar principle.
Storing and Reheating Leftovers
If you’re lucky enough (or let’s be honest, if you made enough so that you have leftovers!), this dish stores wonderfully. Once cooled slightly, transfer any remaining cheesy scalloped potatoes recipe portions into an airtight container. It keeps great in the fridge for about 3 to 4 days. Don’t leave it sitting out for more than two hours, though, because of all that dairy!
When you reheat it, you want to bring back that luscious creaminess! Microwaving works, but you have to do it gently—use 50% power in short bursts, stirring every minute or so, so the cheese doesn’t split or get rubbery. For the absolute *best* texture, I like to reheat it slowly in the oven. Cover the casserole dish with foil and warm it at 325°F (160°C) until heated through. You might need to add a tiny splash of milk (like a tablespoon) to the center before reheating if it looks stiff!
Variations for Your Scalloped Potatoes and Ham Recipe
Now, I know my Ultimate Creamy Slow Cooker Scalloped Potatoes and Ham Casserole is perfect as written, but that doesn’t mean we can’t have a little fun changing things up, right? Since this is such a fantastic base recipe—a true comfort food casserole—it takes flavor variations like a champ! I like to switch things up seasonally, especially if I’ve ended up with a different type of ham than usual.
Don’t feel tied down to just cheddar and Gouda; we can get fancy or keep it rustic depending on what you’re craving. These little twists keep the slow cooker method the same, so you still get that tender texture without any extra work!
If you’re looking for something completely different that screams fancy appetizer instead of hearty dinner, you can check out my Smoked Salmon Cucumber Bites sometime, but let’s stick to potatoes for now!
Cheese Swaps for Maximum Flavor
The cheese blend dictates so much of the final flavor profile. If you want something sharper and nuttier than cheddar, ditch half the cheddar and substitute it with Gruyère. Gruyère melts like a dream and adds a sophisticated, earthy note that pairs wonderfully with the saltiness of the ham. Don’t be afraid to try adding Parmesan, too! Mixing in about a quarter cup of finely grated Parmesan with your flour when making the sauce gives the sauce a lovely, almost gritty sort of savory depth. It’s fantastic!
Herbs That Elevate This Comfort Food Casserole
Because we are cooking this low and slow, fresh herbs can sometimes lose a bit of their punch, but dried herbs work wonders here, especially if you add them right into the cheese sauce mixture. Right before you pour the sauce over the potatoes, stir in about half a teaspoon of dried thyme or dried rosemary. Thyme is my personal go-to for potato bakes—it just tastes like home!
If you decide to use fresh herbs, mix them into the final layer *before* you dot the top with butter. You need their oils to have a little exposure to the heat to release their flavor properly without completely wilting away into nothingness.
Ham Type Variations for Leftover Ham Recipes
The recipe calls for already fully cooked ham, which is great for using up post-holiday leftovers. However, the flavor changes based on what kind of ham it was!
- City Ham: If you use standard, milder deli-style ham, you might want to bump up your salt just slightly in the base layer, or perhaps add a tiny pinch of mustard powder to the sauce to give it more of a savory kick.
- Smoked Ham or Country Ham: If your ham is already strongly smoked (like a thick-cut spiral slice), you might want to go lighter on the salt content in the base layer. This is especially true if you are using smoked Gouda, as the smokiness can become overwhelming if you use heavily smoked ham alongside heavily smoked cheese!
Experimenting with different hams is the best way to keep this recipe feeling new every time you pull out that Crock Pot!
Serving Suggestions for This Easy Ham and Potato Casserole
You’ve got this rich, creamy, cheesy, utterly perfect easy ham and potato casserole simmering away in that slow cooker, and now you need to build the perfect plate around it! Honestly, this dish is so hearty—it’s practically a meal all on its own—so the key to serving it is balancing out all that wonderful decadence.
When I serve this during the holidays, for example, I try to keep everything else bright and light. We want to counteract the butter and cheese just a little bit, you know?
If you’re looking for something comforting but still healthy to go alongside, you absolutely have to plan for some green vegetables. Steamed green beans tossed quickly with a tiny squeeze of lemon juice are fantastic. They offer that little bit of crunch that the soft potatoes don’t have. Or, if you’re feeling a little more effort, lightly sautéed asparagus spears with a little garlic powder work just as well!
But sometimes, I just want to lean fully into comfort food mode, especially when the weather is cold. On those days, a nice, light, brothy soup alongside the scalloped potatoes and ham fills the bowl beautifully. I often make a big pot of my Italian Minestrone Soup. The texture of the soup—full of veggies and a lighter tomato base—just cuts through the richness of the casserole perfectly without weighing the whole meal down. It makes for a seriously satisfying spread that everyone in the family will love!
Another idea is a simple, crisp side salad. Think crisp romaine lettuce, maybe a few cucumbers and tomatoes, dressed very lightly with a sharp vinaigrette. That acidity wakes up your palate right before you dive back into that creamy goodness. It’s all about balance!
Frequently Asked Questions About Scalloped Potatoes and Ham
I get so many questions about this recipe because, let’s face it, cooking potatoes in a slow cooker isn’t always straightforward! People worry about mushiness or getting that perfect cheesy coating. I tried to think of every potential snag when developing this recipe, especially since we are focusing on making the best cheesy potato bake without turning it into a soupy mess!

Can I use Yukon Gold potatoes instead of Russets in this scalloped potatoes and ham recipe?
That’s a great question about potato types! For this specific recipe, I always recommend Russets because they are starchier. That extra starch is what helps thicken our milk and liquid mixture right into a glorious, rich sauce as it cooks slowly. If you use Yukon Golds, they will still taste amazing, but they have less starch. This means your sauce will likely be thinner, leaning more toward a broth than a thick gravy coating. Yukon Golds will hold their slice shape better—so you’ll get a creamier *texture* overall, but less *sauce* immersion. If you use Yukon Golds, go ahead and add that extra half-tablespoon of flour to your sauce mixture just to try and compensate!
How can I make this crock pot potato casserole with ham dairy-free?
I totally understand wanting to adapt recipes for dietary needs! Making this crock pot potato casserole with ham dairy-free takes a little bit of swapping, but it’s definitely doable. You’ll need to replace the milk with a very neutral-flavored plant-based milk—unsweetened soy or oat milk works best because they have enough body to hold up to the flour. When it comes to the cheese, you will need about 1.5 cups of your favorite vegan sharp cheddar and smoked Gouda shreds. Be warned, dairy-free cheese doesn’t always melt or thicken exactly like real dairy cheese does, so you might end up with a texture that’s more ‘soft potatoes in creamy broth’ rather than super-stringy cheese, but it will still taste wonderful!
Is it safe to leave the slow cooker scalloped potatoes and ham on the ‘Keep Warm’ setting for serving?
Yes, using the ‘Keep Warm’ setting is great for serving time! Once your scalloped potatoes and ham are perfectly tender after the initial 6 to 7 hours on LOW, you can safely switch the appliance to the ‘Keep Warm’ setting. I generally find that it’s safe to keep it warm on that setting for about two hours while people are grazing and helping themselves. Just make sure the lid stays on as much as possible so the moisture doesn’t escape. If you need to keep it warm longer than two hours, I would recommend transferring it to a preheated, very low oven (around 200°F) just to be extra safe with all that dairy!
Nutritional Snapshot of This Hearty Family Dinner Idea
Okay, let’s talk about the numbers for this incredibly delicious scalloped potatoes and ham. Because we are using plenty of cheese, full-fat milk, and ham, this definitely falls squarely into the ‘hearty family dinner idea’ category—it’s rich and satisfying, not diet food! But it’s good to know where you stand when you’re loading up your plate.
Here are the estimated values for one generous serving, based on the specific ingredients we used in the slow cooker method:
- Calories: 450
- Fat: 25g
- Saturated Fat: 15g
- Carbohydrates: 38g
- Protein: 25g
- Sodium: 950mg (This is high because of the cooked ham and added salt, so be mindful on other meals that day!)
- Sugar: 6g
- Fiber: 4g
Now, remember what I always say: these figures are calculated based on perfect slicing and exact ingredient measurements! If you use low-fat milk or skip the Gouda, your numbers will shift. If your ham was super salty, your sodium might be higher. Think of this as a helpful guide, not a strict rulebook for enjoying this amazing comfort food casserole!
