Smoking sweet potatoes on a Traeger transforms them into a caramelized, smoky-sweet side dish that steals every meal. The key lies in low-and-slow heat that develops deep flavor while keeping them tender inside.
I first discovered this technique during a coastal ride when I needed a hearty side for smoked ribs—now it’s a staple in my kitchen.
This method requires minimal prep but delivers restaurant-quality results. You’ll work with simple ingredients—just sweet potatoes, olive oil, and a touch of salt—while the Traeger handles the rest.
The magic happens at 225°F, where the sweet potatoes develop a crispy exterior and creamy interior over 2 to 2.5 hours. No fancy equipment needed beyond your Traeger and a little patience.
By the time they’re done, your sweet potatoes will have a glossy caramelized crust, tender flesh that melts in your mouth, and that unmistakable smoky aroma. They’re perfect as a standalone side or paired with grilled meats, making them a versatile addition to any meal.
The best part? They reheat beautifully, so you can prep ahead for busy nights.
Whether you’re feeding a crowd or treating yourself to a smoke-filled dinner, this recipe delivers foolproof, smoky-sweet perfection every time. Let’s get started with the full instructions—your Traeger is about to become your new favorite tool for elevating sides.

The Yukon Gold variety is my go-to because it holds its shape better than other sweet potatoes while developing that perfect caramelized crust. For the best results, buy them fresh from a local farm stand or the produce section of Whole Foods—they should feel firm with no bruises. If you’re short on time, Costco’s bulk sweet potatoes work great too. The Traeger wood pellets make all the difference—stick with hickory or applewood for that authentic smoky aroma. I always grab a fresh bag before starting, as stale pellets can affect the flavor. Pro tip: Soak the wood pellets for 10 minutes before loading them into your Traeger for even combustion.
No smoked paprika? Regular paprika plus a dash of liquid smoke gets you close, but the flavor won’t be quite the same. Want to skip the brown sugar? Maple syrup at half the amount works beautifully—just keep an eye on them to avoid over-browning. Short on garlic powder? One fresh garlic clove minced adds more depth. The apple cider vinegar is non-negotiable for that perfect tender-crisp texture, but if you can’t find it, white vinegar at half the amount will do. For a gluten-free option, ensure your smoked paprika and spices are certified.
These smoked sweet potatoes reheat like a dream—just pop them in a 350°F oven for 15-20 minutes with a splash of water in the pan to keep them moist. Store them in an airtight container in the fridge for up to 5 days, or freeze them for 3 months in portioned containers. I always make a double batch and freeze half—I love having them ready for quick weeknight meals. The caramelized crust gets even crispier after reheating, so don’t skip this step if you’re prepping ahead. Trust me on the full-fat version—it’s worth the extra minute!

Step-by-step instructions for smoked sweet potatoes
Here’s how to transform simple sweet potatoes into smoky, caramelized perfection on your Traeger.
Prep and Marinate the Sweet Potatoes
Peel the 3 lb sweet potatoes and cut them into 1-inch thick rounds or wedges. I like to work with uniform pieces so they cook evenly. Place them in a large bowl and toss gently with the ½ cup extra-virgin olive oil, 1 tbsp apple cider vinegar, and 1½ tbsp diamond crystal kosher salt. The vinegar helps tenderize the potatoes while the oil creates a barrier for even caramelization.
Add the 1 tbsp smoked paprika, 1 tsp garlic powder, and ½ tsp black pepper to the bowl. Mix everything thoroughly so each piece is coated in the marinade. Let the potatoes sit at room temperature for 30 minutes while you prepare your smoker. This resting time allows the flavors to penetrate and the potatoes to come to temperature.
Set Up and Smoke the Potatoes
Load the 2 lb Traeger wood pellets into your smoker and set the temperature to 225°F. I prefer hickory or applewood pellets for this recipe—they add just the right amount of smoky depth without overpowering the sweet potatoes. Allow the smoker to preheat for 15 minutes to ensure even cooking temperatures throughout.
Once the smoker reaches temperature, arrange the marinated sweet potatoes on the grill grates in a single layer, leaving about 1 inch between each piece. This spacing allows for proper air circulation and prevents steam buildup that can make the potatoes soggy. Close the lid and smoke for 2 hours, resisting the urge to peek. Every time you open the lid, you lose heat and moisture.
Add Sweetness and Caramelize
After 2 hours, remove the sweet potatoes from the smoker and brush each piece generously with the ¼ cup brown sugar. Return them to the smoker and increase the temperature to 275°F. The higher heat will help caramelize the sugar and create that beautiful crust we’re after. Smoke for an additional 45 minutes to 1 hour, checking periodically for doneness.
You’ll know they’re ready when the edges are deep golden brown and the potatoes are fork-tender with just a slight resistance in the center. The caramelized sugar will form a glossy crust that gives way to tender, smoky flesh underneath. Be careful not to overcook—they should hold their shape but still be creamy inside.
Rest and Serve
Transfer the smoked sweet potatoes to a serving platter and let them rest for 10 minutes. This resting period allows the juices to redistribute, ensuring each bite is perfectly moist. The contrast between the crispy caramelized exterior and the tender interior is what makes this dish so special.
Serve immediately while still warm. The smoky-sweet aroma will fill your kitchen, and each bite will deliver that perfect balance of caramelized crunch and tender sweetness. These potatoes pair beautifully with grilled meats, as a side dish, or even as a main course with a dollop of whipped cream or a sprinkle of fresh herbs.
Pro Tips For Making Traeger Smoked Sweet Potato
- Crack That Salt: I used to just dump in the 1½ tbsp Diamond Crystal Kosher Salt and hope for the best—big mistake. Freshly crack it yourself with a mortar and pestle or the flat side of a knife. The finer grains cling better to the potatoes and dissolve faster during smoking, so every bite gets that balanced seasoning without clumpy salt crystals.
- Space Them Properly: After burning my first batch by crowding the sweet potatoes on the grill, I learned to leave that 1-inch gap between each piece. It’s tempting to pack them in, but proper airflow prevents steaming and guarantees a crispy crust. Trust me, the extra few minutes rearranging now saves you from mushy, unevenly cooked potatoes later.
- Brush Sugar Like You Mean It: Skimping on the ¼ cup brown sugar is how you end up with bland, sad potatoes. Use a pastry brush or your fingers to generously coat every surface—even the cut sides—before the second smoke. The sugar needs direct contact with the heat to caramelize properly, so don’t be shy. A little less, and you’ll wonder why your dish lacks that sticky, golden magic.
- Resist the Peek: I know, I know—you’re dying to check if they’re done. But every time you open that lid during the first 2 hours at 225°F, you’re messing with the temperature and moisture. Set a timer, walk away, and let the smoker do its job. The potatoes will thank you with even cooking and that perfect smoky depth.
Pro cooking tips for this recipe
Temperature Control
I can’t stress enough how critical 225°F is for this dish—this is where the magic happens. My Traeger’s internal probe thermometer is my best friend here. I set it to 225°F and let it stabilize for 15 minutes before adding the potatoes.
The key is consistency: if your smoker fluctuates more than ±10°F, your potatoes will either be dry or undercooked. I’ve learned the hard way that 225°F is the sweet spot for that perfect balance of tenderness and caramelization. 🌡️
Marinade Matters
The 30-minute marinade rest isn’t just window dressing—it’s essential for flavor penetration. I toss the potatoes with ½ cup olive oil and 1 tbsp apple cider vinegar because the vinegar breaks down the potato fibers just enough to keep them tender.
Skip this step, and you’ll end up with dry, mealy sweet potatoes. I always use Diamond Crystal kosher salt because it dissolves evenly and doesn’t clump. Freshly cracked salt makes all the difference!
Sugar Timing
Adding the ¼ cup brown sugar at the 2-hour mark is crucial—this is when the potatoes are tender enough to caramelize beautifully without burning. I brush it on generously and crank the temp to 275°F for the final 45-60 minutes.
Watch closely during this phase; the sugar will caramelize quickly. I’ve burned batches before when I got distracted—now I set a timer! The result? That perfect glossy crust that’s crispy on the outside but still creamy inside.
Lid Discipline
This is where most people mess up: peeking at the potatoes. Every time you open the lid, you lose 10-15°F of heat and moisture. I’ve trained myself to resist the urge—no peeking until the 2-hour mark.
After that, I check every 30 minutes to ensure even caramelization. Trust me, the wait is worth it. Your patience will be rewarded with perfectly smoked sweet potatoes every time. ⏰
Resting is Non-Negotiable
The 10-minute rest after smoking isn’t just a suggestion—it’s a game-changer. I’ve served potatoes straight from the smoker, and they were juicy but messy. After resting, the juices redistribute, and each bite is perfectly moist.
This step also gives the caramelized crust time to set, so it doesn’t crumble when you serve them. I always tell my guests to wait—it’s worth the extra minute!
Pellet Selection
Not all wood pellets are created equal. I swear by hickory or applewood because they add depth without overpowering the sweetness. Once, I used cherry pellets for a whim, and the result was too fruity. Stick to Traeger’s premium blends or local hardwood pellets for the best flavor.
Pro tip: Soak your pellets for 10 minutes before loading them—they’ll burn cleaner and produce less ash. It’s a small step that makes a big difference!

Frequently asked questions
Why do my smoked sweet potatoes turn out dry instead of tender?
The 30-minute marinade rest with apple cider vinegar is key to keeping them moist—it tenderizes the potatoes before smoking. If you skip this step, they’ll dry out. Also, avoid opening the smoker lid during the initial 2 hours at 225°F, as each opening loses heat and moisture. The 10-minute rest after smoking helps juices redistribute for that perfect creamy texture.
Can I use regular sugar instead of brown sugar for caramelization?
Yes, but brown sugar’s molasses content gives that deeper caramelized flavor. For a quick swap, use white sugar at half the amount (just ¼ cup instead of ½ cup) and watch closely—the sugar will caramelize faster. White sugar lacks the molasses notes, so the crust won’t be as rich.
How do I know when the sweet potatoes are fully cooked?
They’re done when the edges are deep golden brown and the center has just a slight resistance when pierced with a fork—like a ripe avocado. Overcooking turns them mushy, so check them at 2 hours and every 30 minutes after adding the sugar. The caramelized crust should be glossy but not burnt.
Can I smoke these sweet potatoes without the Traeger wood pellets?
Use hickory or applewood chunks instead of pellets for a similar smoky depth. Soak the wood for 30 minutes before smoking to prevent flare-ups. Just monitor the temperature closely—charcoal grills may need adjustments to maintain 225°F. The key is consistent heat, not just the smoker type.
What’s the best way to reheat these leftovers?
Pop them in a 350°F oven for 15-20 minutes with a splash of water in the pan to keep them moist. Avoid microwaving—they’ll turn soggy. For extra crispiness, broil for the last 2 minutes. The caramelized crust gets even better after reheating!
