It’s truly the ultimate dish when you need a great leftover ham recipes casserole that feels special but takes minimal effort.
Gather Your Ingredients for Scalloped Potatoes and Ham
Okay, let’s talk ingredients! This recipe is all about quality layers, so gathering your components is the first fun step. Trust me when I say that precision here—especially with the potatoes—is what separates a good baked cheesy potato layers dish from an amazing one. We need the right blend of tender potatoes, savory ham cubes, and the components for that amazing sauce.
Potato Preparation and Ham Details
You absolutely need Russet potatoes for this, folks. They break down just right when baked! Make sure you peel these beauties and slice them super thin—I mean about 1/8 inch thick. If you have a mandoline, pull it out now; otherwise, take your time. We want uniform layers that cook evenly. Dice up about two cups of cooked ham; whatever you have on hand works perfectly here!
Building the Savory Ham and Cream Sauce Potatoes Base
For the sauce magic, you’ll need your butter, a little onion for depth, and then the liquids: whole milk and some chicken broth. The broth is key; it keeps the sauce from tasting too heavy, giving you that perfect savory ham and cream sauce potatoes flavor we’re aiming for. And don’t forget the nutmeg! It’s a tiny secret that makes all the dairy flavor sing.
How to Prepare the Ultimate Creamy Cheesy Scalloped Potatoes and Ham
Alright, now for the fun part—bringing this gorgeous comfort food casserole to life! First things first, make sure your oven is cranked up to 375°F (190°C). Grease that 9×13 baking dish—don’t be shy here; we want these to slide right out later! Remember those sliced potatoes and diced ham we prepped? Toss them together in a big bowl. They are waiting patiently for their creamy bath.
Creating the Rich Cheese Sauce for Your Scalloped Potatoes and Ham
This sauce is where the magic lives! In a saucepan over medium heat, melt your butter and sauté those chopped onions until they are soft and smelling wonderful—about five minutes. If you want to take this flavor up a notch next time, check out how we handle some deeper aromatics in our guide to caramelized onions—but for now, keep them sweet! Then, you whisk in the flour constantly for a minute to cook out that raw flour taste. This is called a roux, and it thickens everything up perfectly. Now, whisk in your milk and chicken broth slowly, bit by bit, until everything is smooth. Let that simmer, stirring often, until it coats the back of a spoon—that usually takes about 5 to 7 minutes. Okay, critical step alert: Take the sauce OFF the heat before you add the cheese! I mix in the salt, pepper, nutmeg, and honestly, the *entire* mountain of cheddar and Gruyère cheese. Stir until it’s just silk. If you try to melt cheese on direct heat, it splits, and nobody wants stringy potato sadness!
Assembling and Baking the Classic Ham and Potato Bake
Once your sauce is gloriously melted, pour about a third of it over your potato and ham mixture and toss gently—we want everything coated, not drowned! Spread that seasoned mix into your prepared dish for an even layer. Pour the rest of the sauce right over the top. Next, sprinkle that last half-cup of cheddar right on top for that beautiful crust. Pop it into the oven, uncovered, for 50 to 60 minutes. You’ll know it’s done when it’s bubbly, golden, and you can easily slide a fork through those potato layers. Seriously, let it rest for a full 10 minutes after it comes out. This makes it so much easier to serve without everything collapsing everywhere.

Tips for Success with Baked Cheesy Potato Layers
I love hearing from you all when you nail this recipe! Achieving those perfect, tender, baked cheesy potato layers without any crunchy bits or gloppy sauce really comes down to a few small tricks Mia insists on. Remember, this isn’t just throwing things in a dish; it’s about building structure so every serving looks as good as it tastes!
Achieving Uniform Potato Slices
This is non-negotiable, folks! If your slices are uneven, half the potatoes will be mush and the other half will still be hard when you pull it out. Seriously, if you don’t own a mandoline slicer, run, don’t walk! It ensures every potato slice is exactly 1/8 of an inch thick, which means they all cook at the exact same speed. It takes the guesswork right out of the oven time.
Making Ahead Scalloped Potatoes
If you’re planning a big feast, you can totally assemble this dish the day before. It makes for such a relaxed morning! Just go ahead and assemble the entire casserole, cover it tightly, and pop it into the fridge—up to 24 hours is totally fine. The only caveat is that when you go to bake it straight from the cold fridge?
- Don’t panic if it takes longer! You just need to add about 10 to 15 extra minutes to the listed baking time to let it warm through properly before it starts browning.
I also have a great post about how to handle structure in potatoes when making twice-baked potatoes, which focuses on the starch content—it’s helpful context for making sure these layers turn out perfectly!
Variations: Slow Cooker Scalloped Potatoes and Ham Option
Okay, let’s talk about freeing up that oven! You know how much I love my big oven baking days, but sometimes, especially when you’re wrangling holiday cooking, you need that appliance freed up for the turkey or the rolls. That’s why you’ll be thrilled to know this recipe works like a charm in the slow cooker, making for amazing slow cooker scalloped potatoes and ham.
It’s super simple, too. You layer everything just like the oven version—potatoes, ham, and that lovely, rich sauce—right into your greased Crock-Pot. You can cook it on LOW for about 5 to 6 hours, or if you’re in a hurry, HIGH for roughly 3 hours. Just make sure those potatoes are totally tender when you poke them!

This method is a lifesaver, and if you need more slow cooker inspiration after you’ve devoured this, check out our super easy pulled chicken recipe. It uses the same concept for freeing up your oven space!
Serving Suggestions for Your Hearty Potato Side Dish
Since this **hearty potato side dish** is so rich and creamy, you need to balance it out with something bright and fresh on the plate! Seriously, don’t let this ham and potato bake weigh you down entirely; we need some crunch.
I always keep it simple. A big, crisp green salad with a light vinaigrette is perfect—it cuts right through all that cheese sauce. If you need a little more green on the table, nothing beats some quickly steamed green beans or crisp asparagus spears. They go straight into the oven for the last 15 minutes of baking, so minimal extra dishes!
Storage and Reheating Instructions for Scalloped Potatoes and Ham
This casserole is so good, you’ll probably have leftovers, and that’s a win in my book! When you wrap up the dish, make sure you cover it tightly with foil or plastic wrap. Keep it in the fridge for up to four days. It holds up beautifully, which is why I love making it as a prep meal.
To reheat, my preferred method is the oven—it keeps the topping nice and crisp. Cover the dish loosely with foil and bake at 350°F (175°C) for about 20 minutes, just until it’s heated through and bubbly again. If you’re super rushed, the microwave works fine for individual servings, but be aware that the sauce might separate slightly when you do it that way.
Frequently Asked Questions About This Classic Ham and Potato Bake
I get so many great questions about making sure this **classic ham and potato bake** turns out perfect every single time! Since it’s such a beloved casserole, people want to tweak it or make sure they aren’t messing up the base recipe. Here are the ones I hear most often when you’re aiming for the best scalloped potatoes always!
Can I use different types of cheese in this creamy scalloped potatoes and ham?
Oh, absolutely! While I swear by the sharpness of cheddar paired with Gruyère, you can definitely make swaps. If you can’t find Gruyère, Swiss works beautifully, or even Monterey Jack melts really nicely. The main thing I warn against is using fresh, super soft cheeses like fresh mozzarella—they hold too much water and can make your beautiful sauce runny. We need firm cheeses that melt smoothly into that creamy scalloped potatoes and ham sauce!
What is the best potato to use for this cheesy potato casserole with ham?
My official, absolute favorite is the Russet potato. Why? Because they are high in starch. That starch is what helps thicken your sauce naturally as it bakes, giving you that nice, luxurious, thick texture that keeps the layers together. Yukon Golds are a wonderful second choice; they hold their shape a bit better, resulting in a slightly firmer bite. But for pure, melt-in-your-mouth creaminess, stick to Russets!

Ingredients
- 3 lbs Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)

- 4 tablespoons unsalted butter
- 1/4 cup all-purpose flour

- Whisk in the flour and cook for 1 minute, stirring constantly.
- Gradually whisk in the milk and chicken broth until the mixture is smooth. Bring the sauce to a simmer, stirring often, until it thickens enough to coat the back of a spoon, about 5 to 7 minutes.
- Remove the saucepan 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 (if using). Stir until the cheese melts completely into the sauce.
