Seriously, this isn’t just another bake; it’s the creamy, cheesy, perfectly set dish you dream about. Every single variation I tried out in my kitchen—and trust me, I tested a lot—led me right back here. You can rely on this recipe, friends. I’ve triple-checked every ratio so that when you pull this out of the oven, you know it’s going to be golden, bubbly, and frankly, perfect.

Why This Ultimate Cheesy Scalloped Potatoes and Ham Casserole Works

I know you’ve made scalloped potatoes before, and maybe they were okay, or maybe they were a little grainy or watery. Not this one! This recipe earns its “ultimate” title because it’s genuinely reliable. I spent ages perfecting the technique so you don’t have to worry when serving this for a crowd.

  • The sauce stays velvety smooth, never gritty.
  • The potatoes cook evenly right through to the center.
  • It tastes even better the next day! (If you have leftovers, which is doubtful.)

Achieving the Perfect Creamy Scalloped Potatoes with Ham

The secret to luscious, rich **creamy scalloped potatoes with ham** is building a proper roux. We cook the flour in butter just long enough to lose that raw taste, then slowly whisk in the milk and cream. Adding the sharp cheddar and nutty Gruyere off the heat keeps everything silky. That combination is what makes the sauce hug every single potato slice perfectly!

Using Leftover Ham in Your Scalloped Potatoes and Ham

This dish is truly one of the best **leftover ham recipes casserole** options out there, especially after a big holiday meal. Don’t let that ham go to waste! I prefer cubing my ham chunky so you get a nice savory bite with every forkful. Shredding works too, but make sure it’s already cooked, obviously. It adds that salty, smoky depth that potatoes just love.

Gathering Ingredients for Scalloped Potatoes and Ham

Alright, let’s talk about what you need to pull off this glorious **scalloped potatoes and ham** bake. Having the right building blocks makes all the difference, trust me! If you’re nervous about an ingredient list, don’t be. Everything here is straightforward, but the quality matters, especially those potatoes. I always recommend Russets or Yukon Golds for this. They hold their shape just enough while they soften in that creamy sauce.

And hey, while you’re grabbing things for this big side dish, maybe check out my list of other delicious side dishes for inspiration later! The most important prep work here is slicing the potatoes uniformly—about an eighth of an inch thin. If they’re too thick, they won’t get tender in that time frame. A mandoline makes this so painless, though my hands still get speedy with my old mandolin slicer!

Ingredient Notes and Substitutions for Your Hearty Potato and Ham Bake

When we talk about creating that **hearty potato and ham bake**, the cheese choice is huge. Cheddar gives us that sharp, classic flavor, but Gruyere is my secret weapon for silkiness and a wonderful nutty depth. If you can’t find Gruyere, don’t panic! Swiss or even a good Monterey Jack step in nicely, though you might lose that subtle complexity Gruyere brings.

Remember, we’re using cooked ham here, so you’re just heating it through. For the potatoes, stick to Russets if you like a fluffier interior once baked, or Yukons if you prefer a slightly waxy texture that holds up a bit firmer. These details make the difference between a good casserole and *the* casserole everyone asks for the recipe to!

Step-by-Step Instructions for the Best Scalloped Potatoes with Ham

This is where the magic happens, friends! Don’t let the sound of making sauce scare you off. It’s actually really easy once you see it in action. We’re going straight from zero to creamy heaven, I promise. My goal here is to make sure you—yes, you—can nail this **scalloped potatoes and ham** casserole every time without breaking a sweat or ending up with lumpy gravy. We start simple on the stovetop, get those potatoes nestled in their cheesy bath, and then let the oven do the heavy lifting. When you’re done, make sure to swing by my guide on baked cheesy potato side dish ideas for more inspiration after you devour this!

Creating the Rich Cheese Sauce for Scalloped Potatoes and Ham

First things first: we have to build that gorgeous sauce base. You melt your butter, whisk in the flour, and cook that quick little paste—that’s your roux! This next part is so important for a perfect **scalloped potato casserole recipe**: whisk in the milk slowly until it starts to bubble and thicken up nicely on the stove. When it coats the back of a spoon, take it OFF the heat immediately! If you add the cheese while it’s boiling hot, it gets oily. Stir in the cream, then your spices, and finally, toss in most of your cheeses until everything melts into one glorious, smooth blanket, ready for the potatoes.

Layering and Baking Your Scalloped Potatoes and Ham

Now for the assembly line! Spread half your thinly sliced potatoes into your greased 9×13 dish—make sure they overlap a little. Sprinkle half your ham over those spuds, then pour half the sauce right on top. Then, you repeat that sandwich trick: remaining potatoes, remaining ham, and pour the rest of that divine sauce over the top. That finishing sprinkle of your reserved cheddar and Gruyere is what gives us that beautiful crust. Bake it for 60 to 75 minutes. Honestly, if the cheese starts looking too dark halfway through, just throw a piece of foil over it loosely. That’s my best trick for control!

Tips for Making the Perfect Scalloped Potatoes and Ham Casserole

Okay, you have the recipe, but I want you to feel like a total expert when you serve this **classic comfort food dinner**. It’s all in the little details that move a dish from good to absolutely unforgettable. Don’t skip these little checks—they are what make my versions always turn out perfect when I’m hosting!

First up: slicing consistency. I mentioned the mandoline earlier, and I’m bringing it up again because it truly is the key to even tenderness. If you have slices that are super thin next to slices that are close to a quarter-inch thick, guess what? The thin ones turn to mush before the thick ones even feel soft. Aim for that 1/8 inch mark—it might sound fussy, but seriously, your fork should slide through them like butter when it comes out of the oven. That beautiful uniformity matters!

Next, let’s talk resting time. I know you’re hungry, and that casserole smells incredible bubbling away, but you *must* let it sit for 10 minutes after it leaves the oven. Why? Because while it’s resting, those starches in the potatoes are relaxing and absorbing any extra moisture. If you cut into it straight away, you’ll get a soupy mess flowing onto the plate. That short rest sets the whole thing up beautifully. You can check out my tips for other classic comfort food dinner ideas for inspiration on what to serve alongside this rich bake!

One last thing that really elevates this **scalloped potatoes and ham** dish: bloom your spices! After you whisk the nutmeg into the hot sauce (before the cheese goes in), let it sit for about a minute off the heat. This tiny pause awakens the oils in the spice, making the final flavor so much warmer and more complex. It’s a tiny move that makes people go, “Wow, what did you put in this?”

Make Ahead Scalloped Potatoes and Ham Instructions

I am a huge fan of anything that lets me cheat a little bit on a busy weeknight or when I’m hosting a big crowd. If you need to get ahead, this **make ahead scalloped potatoes** dish is your best friend! You can totally assemble the whole thing—potatoes, ham, and that rich sauce—put it all in the glass dish, cover it tightly, and stick it in the fridge. It keeps beautifully for a full 24 hours.

The only thing you have to remember is that chilly ingredients take longer to heat through thoroughly. So, when you finally pop it into that 375°F oven, plan on adding an extra 10 to 15 minutes onto the baking time. Just check for tenderness with your fork like normal, but give it that cushion time. Trust me, for a **family dinner potato casserole**, prepping it the day before is a lifesaver!

Alternative Cooking: Slow Cooker Ham and Potatoes

Now, I know sometimes the oven just can’t handle one more dish, especially if you’re juggling a big holiday meal or trying to keep the house cool. That is why I love this recipe’s versatility! We can totally pivot this into a fantastic **slow cooker ham and potatoes** situation. It takes a little longer, sure, but the payoff is that you’re hands-free, and everything just kind of melds together beautifully in that warm crockpot environment. It’s one of my favorite ways to use the slow cooker, outside of my famous slow cooker beef stew!

The layering is exactly the same as baking—potatoes, ham, sauce, repeat! Just make sure you don’t fill your slow cooker past about two-thirds full, or it won’t cook evenly. And here’s the timing you need to know for your **crock pot scalloped potatoes with ham**:

  • Set it on LOW for about 6 to 8 hours.
  • If you are in a rush (which, who isn’t?), the HIGH setting will get it done in about 3 to 4 hours.

Just remember, since it’s not getting baked under that intense dry heat from the oven elements, the top might not brown up quite as much as the baked version. But honestly, who cares when the potatoes underneath are so tender they practically dissolve? If you’re feeling fancy, you can carefully transfer it to an oven-safe dish for the last 15 minutes or just sprinkle that top layer of cheese on right before serving. For another great slow cooker option, I heard amazing things about a recipe found over here that uses similar methods!

Serving Suggestions for Your Family Dinner Potato Casserole

This **family dinner potato casserole** is super rich, so you want sides that cut through that creaminess, right? You definitely don’t want another heavy starch on the plate! I always pair this with something vibrant and fresh to balance everything out. A simple crisp green salad with a bright, acidic vinaigrette is perfect. It’s a lovely contrast!

Also, some lightly steamed or roasted green beans or asparagus work wonders. If you’re looking for inspiration on crisping up some veggies rather than steaming them, you have to try the method I use for my roasted vegetable lasagna recipe—it gives everything a nice caramelized edge. You just want something simple so this amazing **scalloped potatoes and ham** can truly shine!

Storing and Reheating Your Cheesy Potato Casserole Holiday Dish

If you’re lucky enough to have leftovers of this incredible **cheesy potato casserole holiday** masterpiece—which, let’s be honest, is rare—storing it is super simple. Just let it cool down slightly, cover the dish tightly with plastic wrap or transfer slices to an airtight container, and pop it in the fridge. It stays wonderfully comforting for about three to four days.

When it’s time for round two, I firmly recommend reheating in the oven if you have the time. Cover the dish loosely with foil and bake it at 350°F until it’s heated through, which usually takes about 20 minutes. This keeps the potatoes from getting rubbery! If you’re starving and need it fast, the microwave works, but just do small portions on a plate, and maybe splash a tiny bit of extra milk over the slice before nuking it so it doesn’t dry out. For future soup cravings, I have an amazing broccoli cheddar soup recipe that pairs great with leftover potatoes!

It’s such a reliable dish that you can even prep it ahead! For even more ideas on making these hearty bakes ahead of time, you might want to check out the method detailed over here.

Frequently Asked Questions About Scalloped Potatoes and Ham

I always get so many great questions when people try this recipe for the first time! It’s so rewarding to help folks feel confident serving something this popular. Since this is such a beloved comfort dish, I’ve gathered the most common things readers ask me about making the **best scalloped potatoes with ham**.

Can I use raw potatoes in my scalloped potatoes and ham recipe?

Absolutely, yes! That’s how this recipe is designed to work. The key is to slice them super thin—remember that 1/8 inch mark? Make sure that creamy cheese sauce covers every single slice completely. If the sauce surrounds them, they steam beautifully right in the oven and turn perfectly tender!

What is the best cheese for a creamy scalloped potatoes with ham?

I am partial to that mix of sharp cheddar for flavor and Gruyere for its amazing melt quality and nutty taste. Good melting cheeses are important because they don’t separate and get oily on top. Monterey Jack is a decent replacement if you need to swap it out, but that Cheddar/Gruyere combo is what makes this **creamy scalloped potatoes with ham** shine!

How do I prevent my scalloped potato casserole from being watery?

That’s a common worry, especially since we use milk and cream! My best advice is two-fold. First, give your sliced potatoes a gentle pat dry with a paper towel before layering them in the dish. Second, make sure you let that roux cook just long enough to thicken the milk properly before you take it off that heat. A well-cooked roux absorbs moisture better in the final bake!

Ingredients

Scale
  • 3 lbs Russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 2 cups cooked ham, diced or shredded
  • 1 tablespoon butter, plus extra for greasing dish
  • 2 tablespoons all-purpose flour

  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 1 cup shredded sharp cheddar cheese, divided
  • 1/2 cup shredded Gruyere cheese, divided

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter.
  2. In a medium saucepan, melt 1 tablespoon of butter over medium heat. Whisk in the flour and cook for one minute, stirring constantly to create a roux.
  3. Gradually whisk in the milk until smooth. Bring the mixture to a simmer, stirring until it thickens slightly, about 3 to 5 minutes.
  4. Remove the saucepan from the heat. Stir in the heavy cream, salt, pepper, and nutmeg.
  5. Stir in 3/4 cup of the cheddar cheese and 1/4 cup of the Gruyere cheese until the cheese melts into the sauce. This is your rich cheese sauce.

  10. Bake uncovered for 60 to 75 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly. If the top browns too quickly, loosely cover it with foil for the last 15 minutes.
  11. Let the scalloped potatoes and ham rest for 10 minutes before serving.
