Traeger Ham and Cheese Scalloped Potato Casserole

This Ham and Cheese Scalloped Potato Casserole is one of my favorite ways to make something new out of all that leftover double-smoked ham. Creamy white sauce is poured over layers of thinly sliced potatoes and ham, and then topped with cheese. It is like a ham and cheese lasagna.

I like the ham sliced nice and thin and layered in with the potatoes. If you wanted to save time you could use bagged frozen hash browns for this and cubed ham. You would lose the layered effect, but the end result would be largely the same.

We served this with a big pile of steamed broccoli and some fresh bread.

How to make Ham and Scalloped Potato Casserole on the Traeger

This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.



Fire up the pellet grill and preheat to 325°F.


Make the sauce

Don’t rush the roux. It is a lot of the flavor!



Peel and prep the potatoes by thinly slicing with a mandoline (or a knife if you’ve got the skills).

Layer into your prepped baking dish along with the cheese and ham.


Bake it

Smoke it. Grill it. Whatever you want to call it, but put the casserole dish into the pellet grill (or oven) and let it cook.

It’ll take quite a while. How long exactly depends on how thick you cut your potatoes. An hour or so is within the realm of normal though. Cook until the potatoes are fork tender.



When you pull this off of the grill it is going to be molten lava hot. Let it cool for 10-15 minutes before slicing and serving.
