Sweet potatoes show up to a BBQ like that friend who brings great vibes and also a Bluetooth speaker. They caramelize, they char, they play nice with smoke, and they don’t fall apart if you look at them wrong. Want a side dish that steals the spotlight from the burgers? Fire up the grill and let sweet potatoes do their sweet-savory magic.
Why Grill Sweet Potatoes?
Grilling turns their natural sugars into crispy, caramelized edges with soft, creamy centers. That contrast? Chef’s kiss. Plus, sweet potatoes hold up on grates better than many veggies, so you won’t spend the night fishing slices out of the coals.
They also love bold flavors. You can go smoky, spicy, herby, tangy—whatever your crowd wants. They act like flavor sponges in the best way. IMO, they’re the most versatile side on the cookout table, and FYI, they happen to be packed with fiber and vitamins, too.
Prepping Like a Pro
You only need a few smart moves to nail texture and flavor every time.
- Choose the right size: Pick medium, evenly shaped sweet potatoes for consistent slicing.
- Peel or not? Leave the skin on for sturdier slices and extra nutrients. Peel if you want softer, creamier bites.
- Slice smart: Aim for 1/2-inch thick rounds or planks. Too thin burns; too thick stays crunchy in the middle.
- Par-cook (optional but clutch): Microwave whole potatoes 3–5 minutes until just tender, then slice. This speeds grilling and guarantees creamy centers.
- Oil + season generously: Brush with avocado or olive oil and hit with salt. Sweet potatoes need salt to sing.
Gear Check
– Clean grates and preheat to medium-high (400–450°F).
– Use a thin metal spatula or tongs for clean flips.
– A grilling basket works for wedges if you’re nervous. No judgment.

Smoky Sweet Potato Planks with Herb Feta
Planks look fancy but grill fast. The salty feta balances all that sweetness like a pro.

Move stubborn planks only when they release easily. If they stick, they’re not ready—give them another minute and a little patience.

Timing Hack
Glaze near the end so sugars don’t burn. You want lacquered, not charred-beyond-recognition.

FAQ
Do I need to par-cook sweet potatoes before grilling?
No, but it helps. Par-cooking (microwave or steam) guarantees creamy centers and shortens grill time. If you skip it, slice evenly and give them a bit more time over medium heat.
How do I keep sweet potatoes from sticking to the grill?
Start with clean, hot grates. Oil the potatoes, not the grill, and wait for a good sear before flipping. If they resist, let them go another minute—they’ll release naturally when ready.
What temperature should I use?
Aim for medium-high, about 400–450°F. That range gives you caramelization without incineration. If sugars start to scorch, move pieces to indirect heat to finish.
Can I make these recipes on a grill pan or in the oven?
Totally. Use a hot grill pan on the stovetop or roast at 425°F on a sheet pan. You’ll miss some smoke, but the flavors still pop. Add a pinch of smoked paprika to fake the grill vibes.
Which oils work best for grilling sweet potatoes?
Use high-heat oils like avocado or light olive oil. Save extra-virgin for finishing. The goal: crisp edges without burned oil flavor, because that’s not the kind of smokiness we want.
How thick should I slice them?
Stick to 1/2-inch for rounds and planks, 3/4-inch for “steaks,” and 1-inch cubes for skewers. Consistent thickness = even cooking and fewer tears at the grill.
Conclusion
Grilled sweet potatoes bring caramelized edges, creamy centers, and endless flavor options to your summer spread. Keep the slices even, season boldly, and finish with a punchy sauce or crunchy topper. Then watch the burgers get jealous. Honestly, once you try these, you’ll invite sweet potatoes to every BBQ—speaker and all.
