Why Smoked Sweet Potatoes?

Sweet potatoes are a fun side dish to throw on the smoker alongside your thanksgiving turkey or standing ribeye roast, especially around the holidays.

Or you can just smoke your sweet potatoes them by themselves to accompany literally ANY other meat.

They absorb some great smoke flavor without getting overpowered, and are finished in just about an hour if you fan them out like we do and cook them with some high heat!


Best Wood for Smoking Sweet Potatoes

Hickory, Maple, and Apple are great wood choices that pair wonderfully with sweet potatoes.

You can choose one or the other or mix them together!  These two woods also work great on chicken, turkey, and most beef, lamb, and holiday meats.

You can impart A LOT of distinctive smoke flavor in a relatively short period of time.


How to Prepare Sweet Potatoes for Smoking

Our favorite way to prepare smoked sweet potatoes is by fanning them out and basting them with butter and BBQ rub while they cook.

This works best, and is easiest to clean up afterwards, if you use a good silicone basting brush like these ones.

You get the MAXIMUM surface area of flavor and smoke absorption vs. cooking them whole or just punching them with forks.  You’ll also finish them in about 1/2 the time!

You end up with a sticky, tasty, glaze and lots and lots of smoke flavor throughout the whole sweet potato.

You can eat them just like this or remove the skins and mash them up into asmoked sweet potato casserole if you wish.


Best Times and Temperatures for Smoking Sweet Potatoes

Best Temperature to Smoke Sweet Potatoes

We are going to set the temperature of the pellet grill or smoker to 375°F.

If you are using a grill, make sure to set it up for INDIRECT cooking with all the charcoal or burners lit on the opposite side of the sweet potatoes.

Now you CAN smoke them at a lower temperature, especially if the meat you are cooking them alongside requires a lower smoking temperature.

Just realize they WILL take quite a bit longer to cook so get them on the grill or smoker early!


How Long Does it Take to Smoke a Sweet Potato?

Fanned out at 375°F, your smoked sweet potatoes will take about 60 minutes to fully cook.

If you’re cooking them at 275°F because of the meat, plan on them taking closer to 2 hours.

On the low end of the BBQ spectrum, down at 225°F, you may be better off getting some smoke on them initially and then finishing them in the oven so that the butter/rub mixture gets a nice caramelization as they cook.  This will be tough to make happen all the way down at 225°F.


How Can You Tell When Smoked Sweet Potatoes are Finished Cooking?

Unlike many of the meats we smoke around here, where you have to watch the internal temperature like a hawk, you have some pretty good leeway with smoking sweet potatoes.

Give them about an hour on the smoker or grill, and when they poke through effortlessly with a knife or fork, you know they are done!



Setting up your Smoker for Sweet Potatoes

New to smoking?

Check out our Complete List of the Best Entry Level Smokers for Beginners Here.

Like we said, you are most likely setting up your smoker to cook a main dish for the sweet potatoes to accompany, and if so, make sure to follow THOSE instructions for setting up your smoker.

If, however, you are just in the mood for smoking some sweet potatoes by themselves, here are the best instructions for setting up different types of grills and smokers to do just that.


Vertical or Offset Charcoal Smoker

Fill your firebox or lower charcoal basin with about three chimney’s worth of unlit charcoal and create a small hollowed out depression in the center where you can add your lit briquets.

If your smoker comes with a water pan, like the Weber Smokey Mountain, don’t bother with filling it.

Light a charcoal chimney all the way with charcoal and wait about 20 minutes for it to fully ignite.

Once lit, add the briquets to the center depression you created.

Keep the dampers about 1/2 way to 3/4 open until the temperature is in the 325-350°F range.

Add 1-2 chunks of smoking wood once the smoker is up to temperature and put your sweet potatoes on, preferably in a foil lined pan to catch the melting butter.

Then slowly close down the top and bottom dampers to about 1/3- 1/4 open until you are maintaining a temperature of 375° F.

Place your sweet potatoes on a foil lined baking tray and place them in the smoker.

You can cook them completely in the electric smoker if the temperature goes high enough, or finish them in the oven after they absorb some smokey flavor if you are crunched for time.

Gas or Charcoal Grill

On a gas or charcoal grill you will likely need to use a smoker box filled with wood chips, or a pellet tube smoker filled with wood pellets.

Think you need a fancy smoker to smoke food at home? 

Think again.

Great smoked food can be made right on your current gas or charcoal grill.

Read Everything You Need to Know about Smoker Boxes here, and see a selection of our Favorite Pellet Tube Smokers here.

In the case of sweet potatoes, we would opt for the smoker tube with wood pellets since the smoker box usually only lasts about 30 minutes.  This will save you the hassle of having the refill.

Set up your gas or charcoal grill for indirect cooking with the burners or a small amount of lit briquets on one side and plan for your sweet potatoes to be on the other side.

Remember, we are cooking the sweet potatoes INDIRECTLY, like an oven, not DIRECTLY over the burners or coals.

Once the temperature of your grill is around 325°F, place your smoker box or pellet tube smoker over the lit burners and once smoke begins coming out, place your potatoes on the opposite side.

Continue bringing the temperature up to 375°F.

Best Ways to Serve Smoked Sweet Potatoes

You can have fun with this recipe and add maple syrup, brown sugar, or even pumpkin pie spices in place of the BBQ rub, depending on the occasion and time of year.
