Amazing 1-dish scalloped potatoes and ham

When the weather turns cold, or maybe when you just need a big, warm hug in casserole form, nothing beats a dish bubbling straight out of the oven. I’m Alex, and I really believe that truly satisfying food shouldn’t involve hours of complicated steps. That’s why I’m sharing my recipe for the **scalloped potatoes and ham** casserole that everyone asks me for. If you’ve got some leftover holiday ham staring back at you, this is the dream destination for it! It’s all about that creamy, cheesy goodness that makes you close your eyes when you take that first bite.

Why This Creamy Scalloped Potatoes and Ham Casserole Is a Family Favorite

I know there are a million casserole recipes out there, but this one just hits different. It’s pure, unadulterated comfort food casserole dinners, wrapped up in that gorgeous cheesy foil. I designed this recipe specifically to be a hearty potato side dish that can also stand up as a main event, especially when you’re trying to clear out the fridge after a big holiday feast. Trust me, once you taste that rich sauce, you’ll understand why this recipe has earned a permanent spot on my comfort food rotation.

• The texture is spot-on: tender potatoes swimming in a luxurious sauce.
• It’s incredibly easy to assemble, even if you’re feeling overwhelmed in the kitchen.
• It turns those forgotten bits of leftover ham into something truly spectacular!

Maximum Creaminess with Sharp Cheddar and Gruyère

Okay, here’s where we separate the okay casseroles from the unforgettable ones. I use a two-cheese attack team here. The sharp cheddar gives you that familiar, tangy cheese pull you expect, but the Gruyère? That’s for the subtle nutty undertone and incredible melt factor. This combination is what guarantees you are making the best scalloped potatoes always. Don’t skip the Gruyère!

Perfect for Leftover Ham Recipes Casserole Needs

If you’ve got ham hanging around from Easter or Christmas, this is your answer! So many leftover ham recipes casserole style end up tasting dry, but not this one. The savory ham pieces mingle right in with the creamy sauce, absorbing all that flavor while they bake. It’s genius, really—giving humble leftovers center stage in a dish everyone craves.

Gathering Ingredients for Your Scalloped Potatoes and Ham

Alright, let’s get down to business! For such a rich and satisfying finished dish, the ingredient list for this **scalloped potatoes and ham** is surprisingly straightforward. The secret to making this a truly great bake, not just a good one, lies almost entirely in how we treat the potatoes and those initial steps creating the sauce. We want perfection in every single layer, so pay attention to the slicing, okay? It matters!

Potato Preparation: Slicing Matters

This is non-negotiable if you want them tender but not mushy. You need Russet potatoes—their starch content helps thicken the sauce beautifully as they cook. I insist you peel them (though you can leave the skin on if you’re feeling rustic!). The key measurement here is thickness: aim for about 1/8 of an inch. If you have a mandoline, now is the time to dust it off and wear that safety glove. If you’re doing it by hand, take your time; uniformity is what prevents some layers from being raw while others dissolve!

Building the Savory Ham and Cream Sauce Potatoes Base

We’re making a classic roux base here, which gives us that luxurious mouthfeel. You’ll need butter—always use real butter, please!—and flour to create that base. Then comes the liquid. I’ve tried low-fat milk, and frankly, it makes the whole thing taste thin. Stick with whole milk, and make sure it’s warmed up slightly before you start adding it to the roux. That little step prevents lumps and guarantees a smooth, savory ham and cream sauce potatoes experience.

Step-by-Step Instructions for Classic Ham and Potato Bake

This is the moment of truth! You’ve got your ingredients prepped, your dish ready, and your oven preheating to 375°F. Don’t rush the next few steps—this is where the magic happens that turns simple slices into a decadent, bubbling classic ham and potato bake. If you follow this sequence exactly, your casserole will come out perfect every time. This whole process is actually faster than you think, making it a great option for one of my weeknight dinner rotations!

Creating the Thick, Creamy Scalloped Potatoes and Ham Sauce

First things first, we build that incredible sauce. Start by melting your butter in a saucepan, and then soften those thinly sliced onions until they’re sweet—don’t let them brown, we just want them tender! Next comes the flour; whisk it in well and let it cook for a full minute. This is crucial! We’re cooking out that raw, floury taste. Now, the key to lump-free glory: pour in your warmed milk slowly, whisking constantly. Bring it up to a gentle simmer, stirring until it coats the back of your spoon nicely. If you can run your finger across the spoon and the line stays distinct, you’ve hit that perfect thickness. Once the base is thick, pull it off the heat and stir in your salt, pepper, nutmeg, and *one cup* of that sharp cheddar plus all your Gruyère. Wow, the smell right now is unreal.

Layering the Cheesy Potato Casserole with Ham

Time to assemble our cheesy potato casserole with ham! Grab your greased 9×13 dish. Lay down half of your sliced potatoes evenly across the bottom. Next, sprinkle half of your diced ham right over those potatoes. Then, gently pour half of the sublime cheese-laced sauce right over the top. Don’t worry if it doesn’t look perfectly even; it settles as it bakes. Repeat this whole process once more using the rest of your potatoes, ham, and finishing off with the remaining sauce. Make sure the top potatoes are fully covered so they soften correctly!

SAVE

Baking Times and Achieving the Golden Top

Cover that whole thing tightly with foil. We bake covered for about 45 minutes at 375°F. This initial covered time is essential because it steams the potatoes just enough to soften them completely in that creamy liquid. After 45 minutes, pull it out—carefully, it’s hot! This is when you sprinkle on that last cup of reserved cheddar cheese. Put the dish back in the oven, but this time, leave the foil off. Bake for another 15 to 20 minutes. You know it’s done when the top is bubbly, gorgeously golden brown, and when you pierce a potato slice near the center with a fork, it slides through with zero resistance. Let it rest for ten minutes before diving in; that resting time lets the sauce set up beautifully!

Tips for the Easiest Scalloped Potatoes with Ham Preparation

Look, I want you to succeed. I really do! Too many comfort food recipes fail because of one tiny step that gets missed. Since this creamy, cheesy dish relies on a perfectly smooth sauce and evenly cooked layers, I want to share a couple of tricks I’ve picked up over the years. These aren’t in the main instructions because they are little secrets that elevate the final result. If you nail these two things, your creamy scalloped potatoes and ham will be legendary!

Achieving Smooth Sauce Texture

If you’ve ever had lumpy sauce, you know the absolute dread. It ruins the mouthfeel, right? My number one defense against that? Always, always use warm milk for that béchamel base we make in the pan. If you dump cold milk into that hot butter-flour mixture (the roux), the temperature shock makes everything seize up, and you end up with little hard flour pebbles in your sauce. Heat your milk first—not boiling, just nice and cozy warm—and then whisk it in slowly. It incorporates beautifully, and the result is pure, velvety smoothness. If you need help troubleshooting anything else, please don’t hesitate to reach out on my contact page; I’m happy to help troubleshoot!

Potato Slicing Technique for Uniform Cooking

I told you in the ingredients section that the thickness matters, but I want to emphasize how to get that thickness consistently. If you’re slicing by hand, try to keep your knife blade angled consistently; eyeball-slicing rarely works for this recipe. The absolute best investment you can make for this dish—and for any time you need thin, even slices—is a mandoline slicer. Use the proper guard, slice slowly, and you get perfect 1/8-inch disks every single time across the entire batch of potatoes. That uniformity means every single potato slice cooks at the exact same rate, guaranteeing that tender, melt-in-your-mouth finish we are looking for in this easy scalloped potatoes with ham version.

Variations: Slow Cooker Scalloped Potatoes and Ham

I totally get it. Sometimes the oven is already full of something else, or maybe you just want that slow, steady heat to do the heavy lifting while you hang out. This recipe, my **creamy scalloped potatoes and ham** favorite, adapts beautifully to the slow cooker! Switching to the Crockpot is one of those game-changers that makes this an amazing **comforting winter meal** without the need to babysit the oven. It’s a near-identical layering process, but the cooking times change completely.

If you’re aiming for the slow cooker scalloped potatoes and ham route, assemble everything exactly as you would for the oven—potatoes on the bottom, ham, then sauce—but skip the initial greasing part since the insert usually has a non-stick surface. Ditch the foil top! Instead, put a clean kitchen towel or a few paper towels under the lid before you seal it on. This catches the condensation that builds up so it doesn’t drip back down and make your cheese topping watery. I learned that trick the messy way!

• Set it on LOW heat for about 5 to 6 hours. This gentle cooking melts everything together slowly.
• If you’re rushed, you can use HIGH, but keep an eye on it; it usually takes about 3 hours.
• Crucially, wait until those final 30 minutes to sprinkle on that top layer of cheese. If you add the cheese too early in the slow cooker chaos, it can get greasy and sink instead of forming that beautiful golden crust we love.

This method is fantastic for using up **leftover ham recipes casserole** needs because the ham flavor just marinates beautifully in the cream for hours. You’re still getting that incredibly rich, savory dish you expect from the oven version. You can find more thoughts on maximizing comfort food dishes over on my section dedicated to comfort food!

Make Ahead Scalloped Potatoes and Storage Instructions

I know sometimes life is just too hectic to stand around waiting for a casserole to bake right when you need it. That’s why this recipe is fantastic for make ahead scalloped potatoes planning! Honestly, planning ahead is what separates the stressed cooks from the chill cooks, and I am firmly on the side of chill. You can assemble this entire dish—potatoes layered, sauce poured over, everything ready to go—up to 24 hours before you intend to serve it.

Just follow the layering instructions exactly as written, but stop right before it goes into the oven. Cover that dish TIGHTLY with plastic wrap, making sure you really seal the edges. Then, tuck it into the fridge. It’s best if you use the coldest, deepest part of your fridge for storage. You don’t want it sitting near the door where the temperature fluctuates, especially since we need those raw potatoes to stay safe!

Adjusting Baking Time for Make-Ahead Casseroles

The only real adjustment needed when baking cold is time, time, time. Because that glorious, creamy base is chilled, it takes much longer to heat through than room temperature potatoes. I always add at least 15 minutes to the initial covered baking time. So, instead of 45 minutes covered, plan on a full hour. You’re doing that initial bake just to get the potatoes tender enough to absorb the richness of that cheese sauce we made. Keep an eye on it, but definitely give it that extra buffer time!

When you finally uncover it to add the top layer of cheese, you might need another 5 to 10 minutes on the baking time to get that golden crust perfectly bubbly because the internal temp is lower. But trust me, the flavor infusion you get from assembling it ahead of time is worth the extra wait. It just lets those savory spices really sink into the potato layers. This makes it a perfect candidate for my weeknight dinner rotation if I prep it the night before!

SAVE

Storing Leftovers for Later

If, by some miracle, you have any of this deliciousness left over, cleanup is simple! Let the casserole cool down slightly at room temperature (no more than two hours, for food safety reasons). Cover the dish securely with foil or transfer portions into airtight containers. It keeps beautifully in the fridge for about 3–4 days. When you reheat it, I suggest adding a splash of milk or even a little chicken broth around the edges before popping it back in a 350°F oven, covered, until heated through. That little bit of moisture prevents the edges from seizing up; it keeps that comforting texture intact!

Serving Suggestions for Your Comfort Food Casserole Dinners

Now that you’ve pulled this magnificent, bubbling casserole out of the oven, you need something green to balance out all that cheesy goodness, right? Since the **cheesy potato casserole with ham** is so rich and hearty, you don’t want to weigh down the plate with heavy sides. I usually keep things super simple here—it’s all about texture contrast!

My go-to is a simple side salad tossed with a bright vinaigrette. That acidity cuts through the cream perfectly. If that’s too much effort, just steam some broccoli or green beans until they’re tender-crisp. That little bit of fresh snap is exactly what the doctor ordered. You can find some of my favorite lighter recipes, like vinaigrettes, over on my soups and salads page. Enjoy this main event!

Frequently Asked Questions About This Classic Ham and Potato Bake

Can I use heavy cream instead of milk in this recipe?

Oh, you absolutely can! If you want to bump up the richness factor even more, heavy cream is a fine substitute. But heed my warning: heavy cream is much denser than whole milk. If you substitute cup-for-cup, your sauce might turn out too thick, almost paste-like, once everything bakes together. My trick if I’m using cream is to replace about a quarter of the cream measurement with warm chicken broth or extra milk. That keeps the sauce velvety and rich without making it unbelievably heavy. It helps maintain that perfect consistency we are looking for!

What is the best type of potato for creamy scalloped potatoes?

For this specific dish, where we want the potatoes to soak up that beautiful sauce and become nearly spoonable, Russet potatoes are the champion, hands down. They have that high starch content that breaks down gently during the long bake time, which actually helps thicken the sauce from within. They turn out wonderfully tender. If you prefer a potato casserole that has just a little more bite and structure—maybe you like firmer layers—you can certainly use Yukon Golds. They hold their shape a tiny bit better than Russets, but they don’t absorb the sauce quite as deeply. It’s a matter of preference, but I stick with Russet for that ultimate creamy factor.

Can I skip the onions in the sauce?

You can, sure, but I really wish you wouldn’t! Those onions, cooked slowly in the butter before we add the flour, are what build the foundational, savory flavor right into the sauce base. They virtually disappear once they soften and blend in, adding depth rather than a powerful onion taste. If you have a strong aversion, you certainly can leave them out, but you lose a little bit of that deep character that makes this such a **comfort food casserole dinner**. For me, that subtle sweetness they bring is critical to the final flavor profile!

Ingredients

Scale 1x2x3x

• 3 lbs Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
• 2 cups diced cooked ham (leftover ham works well)
• 1 medium yellow onion, thinly sliced
• 1/2 cup (1 stick) unsalted butter
• 1/2 cup all-purpose flour

Cook Mode Prevent your screen from going dark

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
2. In a large saucepan, melt the butter over medium heat. Add the sliced onion and cook until soft, about 5 minutes. Do not brown the onions.
3. Whisk the flour into the melted butter and onions. Cook, stirring constantly, for 1 minute to cook out the raw flour taste.
4. Gradually whisk in the warm milk until the sauce is smooth. Bring the mixture to a simmer, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes. This is your savory ham and cream sauce base.
5. Remove the sauce from the heat. Stir in the salt, pepper, and nutmeg. Stir in 1 cup of the cheddar cheese and all of the Gruyère cheese until melted and smooth.
6. In the prepared baking dish, arrange half of the thinly sliced potatoes in an even layer. Sprinkle half of the diced ham evenly over the potatoes. Pour half of the cheese sauce over the layers.
7. Repeat the layering process: remaining potatoes, remaining ham, and the rest of the cheese sauce.
8. Cover the baking dish tightly with aluminum foil. Bake for 45 minutes.
9. Remove the foil. Sprinkle the remaining 1 cup of cheddar cheese over the top. Return the dish to the oven, uncovered, and bake for another 15 to 20 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
10. Let the cheesy potato casserole with ham rest for 10 minutes before serving.

Notes

• For a make ahead scalloped potatoes option, assemble the entire casserole (without the final cheese topping) up to 24 hours in advance. Cover tightly and refrigerate. When ready to bake, add 15 minutes to the covered baking time.
• If you prefer a slow cooker scalloped potatoes and ham version, layer ingredients as directed, but use a slow cooker safe dish or line your slow cooker insert with foil. Cook on LOW for 5-6 hours or HIGH for 3 hours. Add the final cheese topping during the last 30 minutes of cooking.
• Using pre-shredded cheese melts smoother; if using block cheese, shred it yourself for the best texture.
