This isn’t some watery, thin potato dish; this delivers that classic, rich texture everyone dreams about, especially when you’re trying to use up that leftover holiday ham! It took Noah’s strategic planning sessions and my hands-on operational testing to nail the proportions, making this recipe a treasured document in our collection of family favorite potato recipes. You can read more about how we turned our kitchen into the foundation of our empire over on our About Us page, but for now, let’s get baking!

This isn’t just another side dish; it’s the star of the show, honestly. It’s baked perfection, and here is exactly why we keep coming back to it:
- It’s the perfect strategy for using up leftover ham after a big holiday—zero waste!

Ingredients for the Ultimate Scalloped Potatoes and Ham
Okay, this is the blueprint part of the operation. Trust me when I say that the exact measurements here are critical for getting that perfect savory ham and cream sauce potatoes balance we designed. Noah always double-checks this section before we mix anything!
Here is exactly what you need for eight hearty servings; make sure you shop for these items ahead of time so your process runs smoothly:
- 3 lbs Russet potatoes, peeled and thinly sliced (and I mean thin—aim for about 1/8 inch thick!), ready for soaking.
- 2 cups cooked ham, diced—use that leftover ham, go for it!
- 1/2 cup yellow onion, finely chopped (don’t skip these, they add so much subtle flavor).
- 4 tablespoons unsalted butter (the real stuff, always!).
- 4 tablespoons all-purpose flour
- 2 cups whole milk, which you need to warm up a bit first.
- 1 cup heavy cream
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg (this makes the sauce taste sophisticated, I promise).
- 2 cups shredded sharp cheddar cheese, divided—remember, you use half in the sauce and save the rest for the top!
- 1 cup shredded Gruyere cheese (this is the secret weapon for deep flavor!).
How to Prepare the Best Scalloped Potatoes and Ham
Alright, this next part is where my Chief of Operations skills really kick in! Getting the timing and construction perfect is key to making sure this dish doesn’t just taste good but holds up beautifully out of the oven. We need to make that incredible sauce first, then build those gorgeous layers. It’s all about precision to achieve that hearty potato side dish texture we love so much.
Preparing the Creamy Cheese Sauce for Scalloped Potatoes and Ham
The sauce is the backbone of any good casserole, right? We start by melting that butter over medium heat in a saucepan. Toss in your chopped onions and let them soften up—about four minutes—so they melt right into the background later on. Next, whisk in the flour quickly to make our roux. This cooks out that raw flour taste in just one minute. Now, pour in your warm milk, slowly, whisking like you mean it! Once it starts simmering and thickens, pull the whole thing right off the heat. This is crucial: only off the heat should you stir in the salt, pepper, nutmeg, and those two wonderful cheeses! If you add the cheese while it’s boiling, it gets clumpy, and we absolutely cannot have a grainy sauce here. It needs to be silky smooth before we move on.

Assembling and Baking Your Cheesy Potato Casserole with Ham
Once that luscious sauce is ready, it’s time for layering—this is how we get those phenomenal baked cheesy potato layers. First, preheat your oven to 375°F and grease that 9×13 dish. Make sure your drained potato slices are ready to go. Spread half of them across the bottom, sprinkle with half of your diced ham. Pour half of your rich cheese sauce over that. Then, we repeat! The final layer of sauce gets topped with the remaining cheddar cheese. Now, cover it tightly with foil and pop it into the oven for 45 minutes. Don’t peek! After that initial covered bake, take the foil off and let it cook for another 15 to 20 minutes until it’s golden and the potatoes are fork-tender. Patience, operator! Let it rest for 10 minutes once it comes out so it sets up properly before you serve this amazing scalloped potatoes and ham.

Variations: Slow Cooker Scalloped Potatoes and Ham
I know, I know. Sometimes you just don’t want to heat up the whole house with the oven, or maybe you need that space for something else, like turkey! Noah loves finding ways to maximize our appliances, and luckily, this recipe transitions beautifully into a set-it-and-forget-it operation.
If you’re leaning toward using your favorite appliance, let’s switch gears to making slow cooker scalloped potatoes and ham. The construction is exactly the same as the big bake: layer the potatoes, layer the ham, pour the sauce over everything. The key difference is the cooking; instead of that 65 minutes in the oven, you let the Crockpot do the heavy lifting.
Keep the lid on tight—no peeking—and you’re looking at about five to six hours on low, or roughly three hours on high. It’s fantastic for making ahead for potlucks! Need more slow cooker inspiration? We have a whole strategy guide dedicated to optimizing your cooker for slow cooker mashed potatoes, too!
Tips for Perfect Scalloped Potatoes and Ham Every Time
Even with a solid blueprint, sometimes the execution needs fine-tuning. We learned this the hard way when our first batch separated—it looked like soup and potatoes divorced! That disaster taught us that the little details make all the difference in achieving those beautiful, savory ham and cream sauce potatoes layers.
First, let’s talk slicing. I cannot stress this enough: consistency is everything. If your slices are uneven, some will be mushy while others are still crunchy when the casserole comes out. If you don’t have a great knife, invest in a mandoline slicer—it’s worth the safety precaution! Second, always warm your milk and cream before adding it to the roux. Cold liquid hitting that hot roux is a surefire recipe for lumps. I learned that the hard way when I tried to rush it one morning!

Finally, please use high-quality, sharp cheddar and Gruyere. Skip the pre-shredded bags if you can; they have anti-caking agents that stop them from melting smoothly. Using real blocks of cheese guarantees that gooey, cheesy goodness our recipe promises.

Make Ahead Scalloped Potatoes and Ham Storage
One of the best parts about planning a big meal is getting ahead of the chaos, right? This recipe is truly built for efficiency, which is why it’s one of Noah’s approved make ahead scalloped potatoes options. If you want to assemble this entire casserole—layering everything exactly as the blueprint says, but skipping the bake—you can cover it up tightly and stick it in the fridge.
It holds up beautifully for a full 24 hours! When you are ready to bake it straight from the cold, you just need to adjust the time slightly. Add about 15 minutes onto that initial covered baking period to give the potatoes time to warm up enough for the sauce to start doing its job.
Once baked, leftovers are fantastic, too! We typically find they stay incredibly fresh stored in the fridge for about three to four days. It’s like having a built-in backup dinner! For even more make-ahead genius, check out how we prep our breakfast egg muffins!
Frequently Asked Questions About Scalloped Potatoes and Ham
When Noah and I were running the final tests on this dish, we realized that having a solid FAQ section is essential—it’s like our final quality assurance check before we send the blueprint over to you! If you’ve got extra questions about how to make sure your creamy scalloped potatoes and ham turns out perfectly rich, check out these common inquiries we sorted out.
What is the best potato for creamy scalloped potatoes and ham?
This is a great question that sparked a lot of debate between us! For this particular recipe, we strongly recommend Russet potatoes. They have a higher starch content, which is amazing for breaking down slightly during that long bake time. This breakdown thickens the sauce naturally, giving you that dense, luxurious texture everyone expects from a classic ham and potato bake. If you use Yukon Gold, which I also love for other things, the result will be a bit firmer and creamier, but less traditional for this casserole style.
Can I use fresh ham instead of leftover ham recipes casserole?
You absolutely can, but since this bake is designed to be a hearty potato side dish rather than a main roast, the sauce relies on the ham being pre-cooked to avoid overcooking the potatoes while the raw ham finishes. If you only have fresh, raw ham chunks, you need to pan-fry them first until they are fully cooked through before layering them into the casserole. If you absolutely have to use raw ham slices instead of diced, you need to slice them paper-thin—thinner than you think—and you might need to add a little extra liquid to your sauce to compensate for the simmering moisture released during baking.

Notes
- For a slow cooker scalloped potatoes and ham version, layer the ingredients as directed, but use a slow cooker safe dish or grease the slow cooker insert well. Cook on low for 5 to 6 hours or on high for 2.5 to 3 hours. Do not cover the slow cooker with foil; use the lid.
- You can make this a make ahead scalloped potatoes dish by assembling the entire casserole (without baking) up to 24 hours in advance. Cover tightly and refrigerate. Add about 15 minutes to the covered baking time if baking straight from the refrigerator.
- Use Yukon Gold potatoes if you prefer a slightly creamier texture that holds its shape well.
