Ham, Potato, & Green Bean Casserole Ingredients
- Butter. You can use salted or unsalted butter.
- Flour. I use all-purpose flour. But if you are wanting to make this gluten-free, gluten-free flour should work too!
- Salt. I’m always cautious with the salt since the ham adds quite a lot of salty flavor.
- Black Pepper.
- Onion Powder.
- Garlic Powder.
- Milk. Any variety will do. If you are using plant-based, it’s best to go with one that is unsweetened.
- Cheddar Cheese. Mild, medium or sharp- it all works great!
- Potatoes. I often use red-skinned potatoes, but really, whatever potatoes you have on hand will work.
- Green beans. I love using fresh green beans, but of course, these can be swapped for canned or frozen.
- Ham. Ham steaks are great for this recipe, but they also are not cheap. So most times I just end up using leftover ham. I think leftover smoked turkey would work great too!
- Breadcrumbs. Using seasoned breadcrumbs adds more flavor to the topping. Only have plain breadcrumbs? Learn how to season them!

FAQ & Expert Tips
Do I need to Peel the Potatoes? Not unless you want to! Unless I’m using older potatoes with thick skins, I typically leave the skins on for added nutrition. Plus, it saves time, which is also great!
Can this be made Gluten-Free? Yes! Simply use gluten-free flour and gluten-free breadcrumbs.
Save Time: Leftover baked potatoes work great for this recipe. I often will have a dinner of baked potatoes a day or two before and make plenty extra so I can make this recipe.
How to Store: Keep leftovers in the refrigerator for up to 4 days.
Leftover Ham: Use this recipe after the holidays to use up your leftover ham.

Great recipe. I didn’t have the bread crumbs and I didn’t want to make any so my shortcut was to add a boxed stuffing to the top. I prepared stuffing according to box directions and spread on top. It worked great. Thanks for sharing the ideas about the French friend onions too. I may try that next time.
Oh, great idea, Jo! Thanks for sharing.
My mouth is watering just reading the comments.
I have Got to try this one.
Thank you so much.
I hope you enjoy it, Barbara! It’s definitely one of those comfort food recipes.
Would you be able to recommend a ready made sauce in place of the scratch cheese sauce? Canned soup of some kind? If I were to use canned soup, would it need a thickener? I appreciate your opinion. J
I cook almost entirely from scratch, so I’m not very familiar with ready made sauces. So sorry!
Made this recipe today. Used tater tots on bottom after browning them, fried onion rings mixed with beans and cheese sauce, and some more fried onion rings on top. Was a great hit. The tater tots added a lot of flavor to the recipe.
So glad to hear that you enjoyed it, Ray! And thanks for sharing the changes you made too. The tater tots sound like a great option for someone that is wanting to cut corners a bit!
So, I used southern style frozen hashbrowns, thawed. Canned green beans, well drained, and threw in some sliced mushrooms. Also added a little sour cream to the sauce. Oh, and divided the recipe by half.
Just put it in the oven, we’ll see.how it turns out!
Your changes sound like they’d be tasty. I hope you all enjoyed it!
Could you use canned green beans? Also could you make it the day before and bake it the next day?
Canned green beans should work fine, Mary! You may not need as much salt if using them though. And while I’ve never made this the day before, I don’t know why it would be a problem. I think I would wait to add the buttered bread crumbs until you are ready to bake it though so they don’t get soggy. I hope you enjoy it as much as we do!
If you can end up having leftovers or cooking it for two days then making ahead is the same thing
We had a bumper crop of green beans, and my aunt mentioned that a green bean, ham, potato, and cheese casserole was a favorite that my grandma used to make for the family. I did have breadcrumbs on hand, but opted to used crunchy fried onions instead. I mixed some into the casserole and I put some on top during the last five minutes of baking. Everyone loved it. There were no leftovers and I didn’t even have time to get a photo before it was all gone.
Oh, the crunchy fried onions sound like a super delicious addition! Thanks for sharing that. And so glad that you all enjoyed it! It’s definitely a crowd pleaser!
