Scalloped potatoes get an incredible upgrade when you smoke them. The wood smoke infuses the creamy cheese sauce and tender potato layers with a subtle smoky depth that you simply cannot achieve in the oven. Topped with a golden, bubbly cheese crust, these are the most requested side dish at any BBQ.

Instructions

Make cheese sauce

Melt butter in a saucepan. Whisk in flour and cook 1 minute. Gradually add milk, whisking constantly. Cook until thickened, about 5 minutes. Stir in garlic, nutmeg, salt, and pepper. Reserve 1/2 cup of each cheese for the top, then stir in the remaining cheese until melted and smooth.

Layer the dish

In a 9x13 aluminum pan (disposable works great for the smoker), layer overlapping potato slices, cheese sauce, potatoes, sauce — 3 layers total, ending with sauce on top. Sprinkle reserved cheese over the top.

Cover and smoke

Cover tightly with foil. Place on a smoker set to 275°F with hickory or pecan wood. Smoke for 1.5 hours until the potatoes are tender when pierced with a knife through the foil.

Pro tip: The foil traps steam so the potatoes cook through, while smoke still infuses through the edges.
