There are few things better than creamy au gratin potatoes, but placing this popular comfort food into the smoker increases the flavor tenfold. We were impressed with the light smokiness, crisped edges, and all that cheesy, buttery goodness. These smoked au gratin potatoes are comfort food taken to another level.

What is the difference between au gratin and scalloped potatoes?

While these two potato casseroles contain a sauce made of milk (or cream), butter, and flour, au gratin also includes cheese. This gives it a delicious golden brown crust, while scalloped potatoes are known for their “scalloped” browned edges.

How long does it take to cook au gratin potatoes on a smoker?

It takes about 1 hour at 350 degrees F. Aim for 2 hours at 275 degrees F if you want it smokier.

Choosing the right potatoes

We prefer medium-sized russets for smoked au gratin potatoes. They contain a fair amount of starch and have a delicious buttery flavor. However, you can use large red potatoes for this dish. We recommend using a mandolin or your food processor to slice the potatoes. You’ll need to scrub them under cold water and dry them well with a paper towel before slicing.

Wash, dry, and slice potatoes. Place them into a microwave-safe dish, cover them with plastic wrap, and microwave for 8 minutes, until slightly tender. Remove from microwave, carefully remove the plastic, and let the potatoes cool for 10 minutes before handling.
