Cheesy Scalloped Potatoes with Ham

Each bite of these tender, cheesy, scalloped potatoes is so good, it’s hard to stop yourself from craving a second or even third serving! While the potatoes themselves are enough to dream about, the addition of ham in the creamy sauce is what really sends this dish over the top.

If you have any leftover ham from Easter, this is the BEST way to use it all up. Well, this and a classic ham and cheese sandwich with mustard of course! But if you’re looking to elevate your leftovers beyond just a classic ham and cheese sandwich, you’ve come to the right place.

These cheesy scalloped potatoes with ham may sound like a dish that requires some elbow grease, but have no fear – this is a true easy recipe! The most work you’ll do here is slicing potatoes, which should take you no time at all. This delicious side dish recipe is fairly quick, super easy, and always yields the cheesiest results!

Speaking of ham, if you are making a ham anytime soon, make sure to check out our favorite Dijon Brown Sugar Ham Glaze. It makes a PERFECT holiday ham every time!

Cheesy Scalloped Potatoes with Ham Ingredients 

Here’s what you’ll need to bake your new favorite side dish. Spoiler – it’s not a whole lot!

  • Butter: Salted or unsalted both work, it’s up to whatever you prefer.
  • Onion: A yellow onion works best as it has a touch of natural sweetness to it. 
  • Flour: All-purpose flour is the best thickener for the sauce. 
  • Seasonings: You’ll need dried thyme, salt, and freshly cracked black pepper to create the best flavor here. 
  • Potatoes: Gold potatoes are always the best for making scalloped potatoes, as they’re the softest and have the best flavor for this cheesy dish. 
  • Ham: Chop up that leftover ham!
  • Cheddar Cheese: We like to freshly grate our cheddar cheese, as freshly grated yields the best results with both consistency and flavor. 

How to Make Cheesy Scalloped Potatoes with Ham

Prepare your kitchen: Preheat the oven to 350°F. Coat a 9×13 pan with non stick spray, set aside. 

Sauté the onion: In a medium size pan, melt the butter over medium heat and add the onion. Sauté onion until it softens and starts becoming translucent, about 3 to 4 minutes. 

Stir in flour and seasonings: Then add the flour and seasonings (thyme, salt, and pepper), stirring until you can no longer see the flour and everything is well combined. 

Add milk: Slowly add the milk, stirring constantly. Cook mixture over medium heat until bubbling and sauce starts to get thick, about 3 to 4 minutes.  

Add ham: Stir in ham and remove from the heat. 

Layer the potatoes: In the bottom of the prepared casserole dish, spread 1/2 cup of the sauce into the bottom of the dish. Then layer a third of the potatoes on top of the sauce. Repeat layering the sauce and potatoes until all are used, finishing with the sauce on top. 

Bake: Top casserole with shredded cheese and cover with foil. Bake in the oven for 50 minutes. Remove foil and return to oven for 10 more minutes. 

Rest: Let the casserole rest for 10 minutes on your countertop prior to serving.

Helpful Tips

  • Prepare the ingredients just right. Chop your onions as fine as you can, and use a mandolin if you can to thinly slice your potatoes. Also, leave the skin on the potatoes! The skins contain vitamin B and C plus iron, calcium, potassium and fiber.
  • Make it ahead. If you plan on making this dish ahead of time, you’re in luck! You can make it ahead of time and store it for up to 2 days in your fridge. Also, it travels very well, so it’s perfect for bringing to potlucks. 
  • Store it properly. In an airtight container in the fridge, any leftovers you have of these potatoes will stay fresh for up to 5 days. 
  • Thin the sauce. If you think your white sauce may be too thin, just stir in about ½ cup of milk to thin it out.

Serving Suggestions

This recipe can be a main or a side, it really can go both ways depending on your mood! If serving it as a main, a side vegetable (like these Southern Green Beans with Bacon) and light green salad would be great sides.

However, here are just a few main courses that would plate perfectly next to some cheesy scalloped potatoes with ham if you wanted a heartier meal!

Can I Prep This Casserole Ahead?

Absolutely, this is a great make ahead recipe! You can fully prepare the casserole up until the baking stage. Instead of baking it, cover the casserole and refrigerate it for up to 48 hours.

Then when ready to serve it, let the casserole warm up on the counter for about 45 minutes and then bake it according to directions in the recipe card!
