You know those nights when you just need a hug in a dish? When everything needs to be warm, cozy, and unbelievably rich? That’s exactly when my favorite classic scalloped potatoes and ham comes out of hiding! I swear, Anya and Lena look to me for the fiery, intuitive dishes, and this one? It sings! We developed this recipe specifically to handle those glorious hunks of leftover holiday ham. Forget dry sides; we are talking about layers of tender potatoes swimming in a velvety, cheesy dream. Trust me when I say this scalloped potatoes and ham casserole is the definition of comfort food perfection. It’s everything you want, smothered in cheese, and it comes together faster than you think!
Why This Classic Scalloped Potatoes and Ham Casserole Stands Out
Look, I make a lot of bold dishes, but when it comes to sheer crowd-pleasing power, this casserole takes the cake—or maybe the potato? This isn’t just another slice of potato bake; it’s designed to be the richest, cheesiest companion to any meal, especially when you’re trying to use up that roast ham sitting in the fridge. We focused hard on making sure it hits all those cozy notes we crave.
- It delivers that unbeatable, bubbling golden top that promises pure comfort food joy.
- The sauce is so velvety and rich, you won’t even think about boxed mixes—I promise!
- It’s the absolute fastest way to turn humble leftovers into a stunning centerpiece. If you loved our classic tuna noodle casserole, you’ll adore this one too.
Achieving the Ultimate Creamy Potato Casserole Texture
The secret weapon here is building a proper roux! We don’t just dump everything together, oh no. By cooking the flour and butter first (we call that a slurry in my head until I get to the stove!), we kill that raw flour taste. Then, slowly whisking in the milk and broth means you get a super smooth base. That sauce thickens just right before the cheese melts in, guaranteeing you end up with a perfect creamy potato casserole, never watery!
Perfect for Holiday Leftover Ham Recipes
If you’ve got that post-Christmas or New Year’s ham staring you down, this is your answer. Dicing it up and tossing it right into the cheesy sauce is brilliant because the ham slightly flavors the sauce as it bakes. It blends right in, making the whole dish feel hearty and intentional, not like an afterthought. It’s my favorite of all the holiday leftover ham recipes because the saltiness of the meat pairs perfectly with the mild Gruyere!
Gathering Ingredients for Your Scalloped Potatoes and Ham
Okay, let’s get real about what goes into making this dream bake happen. Precision matters here, especially with the potatoes, so make sure you have everything ready to go before you even think about turning on the stove! The recipe calls for 3 full pounds of Russets, that diced cooked ham—I always measure mine out—and don’t skimp on the butter! We need 4 glorious tablespoons to start that sauce off right. If you’re organized, this whole process, even the ingredient gathering, takes no time at all. Check out the full list below, but stick to these amounts, friends! If you’ve enjoyed our broccoli cheddar squash casserole, you know I love a good, hearty bake!
Ingredient Notes and Cheese Substitutions
While the recipe calls for Russets, which I love because they break down just enough to thicken the sauce beautifully, you could try Yukon Golds if you prefer a slightly firmer texture. But the real fun is the cheese! We’re using sharp Cheddar for that classic tang and Gruyere which melts like a dream. If you want to follow that amazing Pinterest trend I saw, try swapping the Gruyere for smoked Gouda! It adds this incredible smoky depth to the whole cheesy potato bake with ham. It’s totally optional, but wow, worth the extra trip to the deli counter!
Step-by-Step Guide to Making Scalloped Potatoes and Ham
Now for the fun part—putting this incredible scalloped potatoes and ham casserole together! My biggest piece of advice right up front is about the slicing. You need your potatoes thin! I mean really thin. If you don’t have a mandoline, take your time with the knife. Think paper-thin slices; it helps them cook evenly and makes the final texture dreamy. Once your 9×13 dish is greased and your oven is cranked up to 375°F, we dive right into the sauce! We want this dish to be completely luscious, just like the sauce in my favorite spinach and squash casserole.

Creating the Rich Cheese Sauce for Scalloped Potatoes and Ham
First thing is melting that butter and letting the onion sweat until it’s soft, not brown—we’re aiming for sweet, not sharp here. Then, whisk in the flour for literally one minute. This is building our base, our roux! Don’t walk away; you need to stir it constantly. Once that’s done, slowly, slowly start pouring in that milk and broth. You have to whisk while you pour, or you get lumps, which are the enemy of a creamy potato casserole! Keep stirring over medium heat until it looks like melted velvet and coats the back of your spoon easily. Take it off the heat before stirring in the cheeses. Stir until it’s silky smooth again. Remember to add that pinch of nutmeg; it just brightens everything up!
Assembly and Baking Times for the Cheesy Potato Bake with Ham
Now for the toss! In a big bowl, gently fold those thin slices of potato and the diced ham into that gorgeous sauce. You want everything coated, but don’t go smashing the potatoes around; we want them to keep their shape. Scoop it gently into your prepared dish, making sure it’s an even layer. Then, you get to sprinkle the last bit of cheddar cheese right on top—that’s what makes the crust! Bake it for 50 to 60 minutes. How do you know it’s done? Don’t rely just on sight! Stick a fork in the center potatoes; if it slides in with zero resistance, you nailed it! Then, pull it out and let it rest for a full 10 minutes before cutting. This lets the sauce settle so your slices stay intact. If you want even more tips on achieving that perfect bake, you can check out some other great methods right here. We want this cheesy potato bake with ham to hold its shape!

Tips for the Best Scalloped Potatoes and Ham Every Time
Even though this recipe feels like magic—and honestly, it usually is—we still need to talk about making sure it comes out perfect if you stray from the path. The biggest pitfall I see when people try dishes like this is rushing the sauce or cutting the potatoes unevenly. Uneven slices mean some are mushy cardboard while the others are still raw in the center, and we just can’t have that! Remember what I said about the mandoline? Get those slices uniform!
Since we’re all busy juggling dinner, work, and spontaneous dance parties, this recipe is a lifesaver because it really loves being prepared ahead of time. It’s a genuine make ahead potato casserole champion!
How to Make Ahead Potato Casserole Success
Here’s the trick for the best make ahead potato casserole for a busy morning: Assemble the entire thing—potatoes, ham, sauce, the works—in your greased 9×13 dish. Cover it tightly with plastic wrap and tuck it into the fridge for up to 24 hours. When you pull it out the next day, it might look a little settled, but don’t worry! Just let it sit on the counter for about 20 minutes while the oven fully preheats. When you bake it directly from the fridge, add an extra 10 minutes to the standard baking time. This ensures those potatoes get deeply tender without risking scorched cheese on top. If you want to try something fun alongside this, my cheesy zucchini cheese muffins are also great for making early!

Serving Suggestions for Your Hearty Winter Dinners
You know this dish is completely filling on its own, right? It’s the definition of a hearty winter dinner! Because the potatoes and ham are so rich and decadent, I always try to pair them with something light and crisp to cut through that creaminess. A simple, bright green salad with vinegar-based dressing is fantastic—it just wakes up your palate! Steamed asparagus or quickly sautéed green beans are also winners. This wonderful potluck side dish cheesy enough to steal the show, but it plays nicely with roasted chicken or pork tenderloin if you need a main course!
If you’re looking for another bright green side, you absolutely must try my Brussels sprouts and bacon pasta recipe sometime soon—it’s got tang and crunch!
Storage and Reheating Your Scalloped Potatoes and Ham
Oh, the glorious leftovers! If you manage to have any of this cheesy goodness left over—which, honestly, only happens at my house by sheer force of will—you want to handle it right. Storing it incorrectly means sad, hard potatoes the next day, and we aren’t having that! Once the casserole has cooled down just slightly, cover it up tightly with plastic wrap or foil. Then, tuck it into the fridge. It keeps beautifully for three to four days. My rule is: if it lasts longer than that, you need to freeze it!
When it comes to reheating, this is where we need to be gentle to keep that lovely texture. The microwave is fast, sure, but it can make the edges tough. I always prefer using the oven if I have time. Scoop out your portion, put it in a small, oven-safe dish, cover it loosely with foil, and heat it up at 350°F until it’s hot all the way through. That usually takes about 15 to 20 minutes. If you’re microwaving, use 50% power in short bursts, maybe 45 seconds at a time, stirring in a tiny splash of milk if it looks dry. It keeps the sauce from completely breaking apart.

If you’ve ever made my chocolate chip zucchini bread, you know I’m big on texture preservation, and these potatoes deserve the same respect! This approach ensures every reheat tastes almost as good as the first bubbly slice.
Frequently Asked Questions About Scalloped Potatoes and Ham
I always get so many questions when it comes to digging into these cheesy bakes, because everyone wants that perfect texture, right? This recipe leans heavily into the creamy side, but I know a lot of you are looking for ways to save oven space, especially around the holidays when the oven is slammed! Don’t worry, we absolutely can adapt this for different cookers!
Can I make this a slow cooker scalloped potatoes and ham recipe?
Yes, you totally can dive into the world of slow cooker scalloped potatoes and ham! If you want to use your Crock Pot, the main thing you’ll adjust is the potato tenderness. Since the heat is more gentle, I strongly recommend you slightly par-cook your thin potato slices for about five minutes before dumping everything in. Also, increase your liquid by about half a cup—milk or broth works fine—just to account for any evaporation. Check out a fantastic guide on how to do that exact thing over here!
What is the difference between scalloped potatoes and potatoes au gratin?
This is such a classic kitchen debate! Simply put, if it has a creamy sauce made primarily of milk, broth, and a roux, it’s scalloped. If it’s baked with cheese layered *throughout* the spuds, it edges over to become an au gratin. Since we bake our cheese mostly on top, we are solidly in the scalloped camp, though if you used a lot of cheese, it definitely gives off that amazing crock pot ham and potatoes au gratin style flavor!

Ingredients
- 3 pounds Russet potatoes, peeled and thinly sliced
- 2 cups cooked ham, diced
- 1/2 cup sweet onion, finely chopped
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup chicken broth
- 1 teaspoon salt

- 1/4 teaspoon nutmeg
- 2 cups shredded sharp cheddar cheese, divided
- 1 cup shredded Gruyere cheese
Instructions
- Preheat your oven to 375 degrees F. Lightly grease a 9×13 inch baking dish.
- In a large saucepan, melt the butter over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
- Whisk in the flour and cook for 1 minute, stirring constantly to create a roux.
- Gradually whisk in the milk and chicken broth until the mixture is smooth. Cook, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes.
- Remove the sauce from the heat. Stir in the salt, pepper, and nutmeg. Add 1 1/2 cups of the cheddar cheese and all of the Gruyere cheese. Stir until the cheese is melted and the sauce is smooth.
- In a large bowl, gently toss the thinly sliced potatoes and diced ham with the cheese sauce until everything is evenly coated.
- Pour the potato and ham mixture into the prepared baking dish, spreading it into an even layer.
- Sprinkle the remaining 1/2 cup of cheddar cheese over the top of the casserole.
- Bake for 50 to 60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.

Notes
- If you are using raw potatoes, you may need to increase the baking time by 10 to 15 minutes to ensure they are fully tender.
- This recipe is excellent for making ahead. Assemble the entire casserole, cover it, and refrigerate for up to 24 hours before baking. Add about 10 minutes to the covered baking time if baking straight from the refrigerator.
- For a smoky flavor, substitute smoked Gouda cheese for the Gruyere cheese.
