If you love ham and potato soup, you’re going to LOVE this easy casserole. I take elements found in any good potato casserole method, like diced potatoes, cheddar cheese, and garlic, and add in chunks of savory ham and a creamy homemade sauce.

Everything is seasoned to perfection and baked until bubbly and golden brown on top. It’s the ultimate comfort food! Here’s what you’ll need to make this cheesy ham and potato casserole:

- Yukon Gold Potatoes: These creamy, buttery potatoes are perfect for this casserole. They cook pretty quickly and hold their shape well. I used 2 lbs total, which was the perfect amount for my 9×13-inch casserole dish.

Russet potatoes will also work well if that’s what you have to hand! - Ham Steak: This can usually be found in the refrigerated packaged meat section of the grocery store, near the bacon. I diced up the ham and then browned it in the skillet for extra taste!

- Cooking Oil: I use a little oil to help brown the ham in the skillet. Any cooking oil will work here, like canola, vegetable, or olive oil. - Yellow Onion & Garlic: These two components are staple aromatics in my kitchen.

They add a ton of savor to any method! - Salted Butter & All-Purpose Flour: The butter softens the diced onion and minced garlic to release their flavors.

Then, once that is done, I sprinkle in some flour to create a simple thickening agent (a roux!) for the creamy sauce. - Chicken Broth: Adds a delicious, savory taste to the casserole.

You can use homemade or store-bought broth, or do what I do and use Better than Bouillon. - Whole Milk: Helps to create a creamy texture in the sauce without being too heavy.

- Seasonings: This savory dish needs salt and pepper, but I in addition add some garlic powder and Tony Chachere’s Creole seasoning. The flavor combination of these seasonings is what sets this recipe apart from others I’ve tried!

You can use any Cajun or Creole seasoning if you don’t have Tony Chachere’s. - Sharp Cheddar Cheese: You definitely want to stick with sharp cheddar cheese for this recipe.

It adds a strong, tangy, pronounced taste compared to regular mild cheddar. - Green Onions: Garnish with sliced green onions just before serving for a little crunch and extra taste.

Yes, this recipe for ham and potato casserole is great for using up leftover deli ham or baked ham from a holiday dinner! I’d slice up the leftover ham into small pieces and use them in place of the ham steak called for in my method.

And since it’s already cooked, there’s no need to brown it in a skillet first (unless you want that extra layer of taste!). My ham potato and cheese casserole is SO easy to make…but that doesn’t mean I don’t have a few tips & tricks up my sleeve.😉 I want you to get this casserole right the first time, and these tips will help!

- You’ll only need to par-boil the potatoes for a few minutes in this recipe as they’ll continue cooking in the oven. I highly recommend you set a timer and drain the potatoes as soon as the time is up to prevent them from over-cooking.

- I also recommend shredding the sharp cheddar cheese from a block for the best taste. Going to Those bags of pre-shredded cheese might be convenient, but they often have, starches and preservatives that can affect the melt and taste. - Don’t cover the casserole dish while it bakes.

You want any exposed pieces of ham to get a little crispy and that cheese to slightly brown on top. - I use a 9×13-inch baking dish when making this casserole, and I don’t recommend using anything smaller than that (unless you reduce the component amounts). You want enough room for everything to fit so it cooks evenly and doesn’t bubble up and over the sides!

Serving Suggestions

This recipe makes 6 generous servings, but if you’re serving this with a big breakfast or brunch, you can probably make the servings stretch a little bit further. I like to serve this quick ham and potato casserole with eggs (usually poached or scrambled) and fruit.

Some maple sage breakfast sausage, buttered toast, or crispy air fryer bacon would in addition go down a treat! However, this recipe isn’t just for breakfast and brunch. I had it with a simple side salad and baked chicken drumsticks for dinner the other day, and it was just as delicious!

This recipe really is versatile and I could honestly eat it any time of the day. One thing I love most about this ham and potato cheese casserole is that it can be made ahead of time.

I sometimes prep everything and assemble the casserole, but instead of baking it right away, I let it cool, then cover and refrigerate for up to 24 hours. This is a time saver on busy mornings or if you’re hosting brunch!

When I’m ready to bake it, I let the casserole rest on my kitchen counter as the oven preheats and then add a few extra minutes to the baking time. It’s ready when the cheese is melted and it’s bubbling around the edges.
