Gathering Ingredients for Creamy Scalloped Potatoes and Ham

Alright, let’s talk about what you need to gather up. I’ve gotten this down to a science in my kitchen to make sure this creamy scalloped potatoes and ham situation turns out perfectly in the Crock Pot every time. You’ll need about three pounds of Russet potatoes, and please, peel them first! They need to be thinly sliced, which is important for that slow-cooker tenderness.

We’re using about a cup and a half of diced cooked ham—this is fantastic for your leftover ham recipes, so don’t stress about buying a special ham just for this! For the cheese, we mix sharp cheddar with Gruyere. That combination gives us the best flavor payoff. And remember that flour? It’s key to getting that nice thickness in the sauce once everything cooks down, so even though it seems small, don’t skip it!

Specific Ingredient Notes and Substitutions

When you slice those potatoes, aim for paper-thin if you can manage it, about 1/8th of an inch. If they are too thick, they won’t get that melt-in-your-mouth texture in the slow cooker.

If you can’t find Gruyere, don’t panic! Swiss cheese works fine, or even a little Monterey Jack will give you that good, melty pull. If you happen to have smoked ham, absolutely use it! That smoky note wakes up the whole casserole and makes it taste even richer.

The flour, which we whisk into the milk and cream, isn’t for structure in the cake sense, obviously, but it’s a little trick to help that liquid thicken up nicely around the potatoes so you don’t end up with watery soup at the bottom of the slow cooker. It’s essential for that classic, thick sauce!

Step-by-Step Instructions for Perfect Slow Cooker Scalloped Potatoes and Ham

This is the part where we put it all together, and trust me, it’s surprisingly simple because the slow cooker holds everything steady for us! We don’t need fancy timing or constant stirring here. First things first, grab your slow cooker insert and give it a good grease up with a little melted butter or even just some spray. We absolutely do not want this masterpiece sticking to the bottom!

Next up is making that velvety sauce—this is the soul of our scalloped potatoes and ham. In a separate bowl, you’re going to whisk the heavy cream, milk, flour, salt, pepper, and garlic powder together. Seriously, whisk until that flour is totally dissolved. If you leave clumps, you’ll end up with little starchy pockets later, and we want pure, smooth comfort here. If you want an extra creamy sauce later, sometimes I whisk in a bit of leftover garlic aioli—just kidding! But seriously, get that sauce smooth.

Building the Layers for Your Scalloped Potatoes and Ham Casserole

Now for the fun assembly! To make sure everything cooks evenly, we build this casserole into two distinct layers. Start by laying down half of your thinly sliced potatoes in the bottom of the greased crockpot. Don’t jumble them; try to make a nice, flat layer.

Over those potatoes, spread half of your ham pieces and half of your thinly sliced onions. Keep that even distribution going! Then, pour exactly half of that lovely cream sauce mixture right over the top of that layer. You need to repeat this entire process: potatoes, then ham and onion, and finally, the remaining sauce.

Don’t add the cheese yet! We save the best part for last. Sprinkle all that delicious cheddar and Gruyere right on top of the final sauce layer. And here’s a little secret Mike learned—drizzle the two tablespoons of melted butter right over the cheese. It helps it brown up so perfectly, even in the slow cooker!

Cooking Times and Achieving Tenderness in the Crock Pot Potato Casserole with Ham

Time to close the lid and walk away! Cover it up tight. You have two options here, depending on when you want dinner: cook on LOW for about 6 to 7 hours, or if you’re in a pinch, you can do HIGH for 3 to 4 hours. Either way, those layers will meld together beautifully.

When the time is almost up, you must check for doneness. Don’t just trust the clock! Carefully lift the lid (watch out for that steam!) and pierce one of the thicker potato slices near the center with a fork. If it slides in easily, you’re golden. If it fights you, put the lid back on and give it another solid 30 minutes on high.

Once they are tender, do NOT pull it out immediately. This step is crucial for any crock pot potato casserole with ham: take the lid off and let it sit right there on the warm setting for 10 minutes before scooping. This resting period lets the liquid settle and really lets that sauce firm up into the perfect, thick consistency.

Tips for the Best Cheesy Scalloped Potatoes Recipe

Even though this is the super easy slow cooker method, we still have a few little secrets to make sure this turns out to be the best cheesy potato bake you’ve ever made. Remember when I told you to let it rest for ten minutes with the lid off? That’s our secret weapon for thickening!

If, however, you pull the lid off and you still want it just a touch thicker—maybe you like it super dense, almost like a true baked ham and potato gratin—just let it sit uncovered on HIGH heat for the last 15 minutes. The steam needs to escape so the sauce can reduce down. Be careful not to leave it too long, or the top layer of cheese might get tough!

Now, I know the slow cooker is the star here, but sometimes life calls for baking. If you need this for a holiday feast and your Crock Pot is already full, you can totally transfer the layers into a 9×13 inch dish. Bake it at 375°F (190°C) for about an hour to seventy-five minutes until it’s bubbly and golden. It’s just as wonderful, but obviously, you’ll have to stand by the oven instead of wandering around the house!

For flavor, don’t underestimate using smoked ham if you have it. It adds so much depth to the overall dish. It pairs beautifully with the sharp cheddar and makes this already great casserole taste like something out of a professional kitchen. You can find some other great side dish ideas, like my crispy garlic skillet potatoes, if you need variety!

Make Ahead Scalloped Potatoes and Ham Storage

One of the big wins with this scalloped potatoes and ham dish is that it’s actually fantastic for meal prep! Honestly, sometimes I assemble the whole thing right in the slow cooker insert the night before, cover it tightly, and stick the whole thing—insert and all—right into the fridge. It’s such a savior when you are facing a chaotic morning.

When you assemble it ahead—potatoes layered, ham scattered, sauce mixed and poured over—just make sure you keep that topping of cheese off until right before you plan to turn the cooker on. Dairy melts weirdly when it sits in liquid and gets cold, so we save that for last. For freezer prep, this is less ideal for storing fully made, because liquid-heavy potato dishes often mess up the texture when thawed, but you can freeze the raw, layered potatoes and ham (no sauce!) and then top with the sauce right before cooking from frozen, adding about 2 extra hours to the low cook time.

If you made a giant batch and have leftovers—which is likely, because this comfort food casserole is addictive—storage is simple. Keep the leftovers in an airtight container in the fridge for up to four days. I love finding good make ahead scalloped potatoes and ham storage tips!

Reheating this creamy casserole is easy, but you need to be gentle so it doesn’t break apart. I find the best way is actually on the stovetop or in a small saucepan over medium-low heat, stirring frequently. You might need to splash in just a tiny bit of extra milk to loosen that sauce up again since it thickens significantly after chilling. You can also microwave individual portions, but stirring every minute or so ensures you don’t end up with hot spots alongside cold centers!

Serving Suggestions for Your Scalloped Potatoes and Ham

Since this scalloped potatoes and ham casserole is so rich, creamy, and totally satisfying on its own, the key to serving it well is adding something bright and fresh to the plate. You want some balance, right?

For a really easy weeknight meal, I usually just steam some bright green broccoli or snap peas. The crunch is divine against the soft potatoes. But if you’re preparing this for a big holiday spread, you need to make it feel special!

It pairs beautifully with roasted asparagus or a simple tossed salad with a sharp vinaigrette. This dish is hearty enough to be the main event, but as one of your favorite holiday potato side dishes, it shines next to ham steak or roast chicken.

Frequently Asked Questions About Scalloped Potatoes and Ham

It’s totally normal to have questions when bringing a new casserole into your rotation, especially when you’re trying to make the perfect cheesy scalloped potatoes recipe. I get asked similar things every time I bring this dish to a potluck! Here are the things I hear most often about making our creamy potato casserole successful.

Can I use Yukon Gold potatoes instead of Russets in this scalloped potatoes and ham recipe?

Yes, you absolutely can, but you need to know the texture difference! Russet potatoes are starchier, which means they break down just a tiny bit more during the long cook time, helping to naturally thicken up that creamy sauce we love so much. Yukon Golds are creamier but they are also firmer. They hold their shape better, which might mean your finished product is more like a classic baked ham and potato gratin with distinct slices—less of that super soft, spoonable texture. Use Yukon Golds if you prefer defined slices, but honestly, I stick to Russets for peak creaminess.

How do I make this a baked ham and potato gratin instead of slow cooker?

This is such a good question for when the slow cooker is already occupied with, say, a giant roast! You can definitely use the oven for this one. Just layer everything exactly as instructed—potatoes, ham, onions, sauce, cheese—but move it into a greased 9×13 inch baking dish instead of the slow cooker insert.

Pop it into a preheated oven at 375°F (190°C). You’ll want to bake it for about 60 to 75 minutes. You’re looking for that lovely bubbly sound and beautifully browned top. It’s a fantastic way to get this easy ham and potato casserole ready for holiday dinners when oven space is at a premium!

What is the best type of ham to use in this Crock Pot Potato Casserole with Ham?

The best ham is the one you already have! If you have leftover baked ham from a holiday, dice it up and throw it in. If you’re buying ham specifically for this, I highly recommend using smoked ham if you can find it. That hint of smoke really elevates the whole experience and pairs wonderfully with the cheddar cheese. Avoid using fresh, uncooked ham, though; we need that meat already cooked and ready to just gently heat through in the sauce.

Can I make this cheesy scalloped potatoes recipe without using flour to thicken the sauce?

You can try, but I strongly advise against skipping the flour if you are using the slow cooker method. The flour, whisked into the liquid, is what ensures you get that thick, luscious sauce that coats every single potato. If you skip it, you will end up with a much thinner liquid pool at the bottom. If you absolutely must skip it, you might need to finish the dish uncovered on HIGH for the last 30 minutes, relying on the evaporation to thicken it up, but it won’t be quite the same luxurious sauce we’re aiming for in this comfort food casserole.

Nutritional Estimate for This Comfort Food Casseroles Dish

Okay, let’s talk about the numbers for a minute. Because this is loaded with creamy sauce and cheese, it is definitely a decadent dish—that’s what makes it such a wonderful comfort food casserole, right? I always tell people to enjoy it when they can because it’s totally worth the splurge!

Based on the ingredients we used—the heavy cream, the cheddar, the ham, and the potatoes—here is the estimated nutritional information per serving. Remember, this is just an estimate based on my recipe breakdown, and what kind of ham you used or if you skimped on cheese can totally change these figures!

  • Calories: 450
  • Fat: 28 grams (with 16 grams being saturated fat)
  • Carbohydrates: 35 grams
  • Protein: 20 grams
  • Fiber: 3 grams
  • Sodium: 750 mg
  • Sugar: 6 grams

It’s certainly on the higher end for fat and sodium, which is what you expect from a rich, creamy, cheesy potato bake like this one! If you are watching sodium, make sure you use low-sodium ham for your make ahead scalloped potatoes and ham preparation. Enjoy a reasonable portion, maybe pair it with a big green salad, and definitely don’t feel guilty. This is meant to be soulful, hearty food!
