I love sweet potatoes! They make some of my favorite side dishes, all year round.

These grilled sweet potatoes take just a few minutes of hands-on time. I season them simply and wrap in foil to help trap the moisture and keep them fluffy. ThenI let the grill do all the work, resulting in tender, perfectly sweet and salty sweet potatoes every time!

In fact, I don’t think I’ll ever go back to traditional baked sweet potatoes in the microwave or oven. Throwing them on the grill creates the best sweet and salty, tender and crispy finish.

Substitutions and Variations

  • Sweet Potatoes – Select sweet potatoes of similar size so that they grill evenly. Look for firm sweet potatoes at the store, with smooth skin, void of bruising or cracking.
  • Olive Oil – Canola oil or melted butter make great substitutes.
  • Optional – Sea salt and brown sugar. If you love all things sweet and salty, you’ll love this combination!

Tips from My Test Kitchen

  • Make Ahead – Season and wrap your sweet potatoes in foil and keep in a refrigerator (or cooler for camping) for up to four days.
  • I generally use a heavy duty foil because it’s so great for grilling.
  • Choose longer, skinnier sweet potatoes that cook faster. If you choose larger sweet potatoes, adjust your grill time to accommodate – they will take longer.
  • Poke sweet potatoes with a fork to release heat and steam as they bake on the grill.

Sweet potatoes can be topped in so many delicious ways! Try Honey Butter or even Hot Honey for a deliciously savory and sweet experience.

Julie’s Tips

  • Prep in advance! Just season and wrap your sweet potatoes in foil. Keep them in your fridge (or cooler for camping) for up to four days.
  • If you choose larger sweet potatoes, you’ll need to adjust your grill time to accommodate.
  • Choosing a longer, skinnier sweet potato means it will cook faster!
  • Poke each potato with a fork to release heat and steam as they bake on the grill.

Storage 

I refrigerate grilled sweet potatoes for up to a week, wrapped in an airtight container. I also freeze sweet potatoes! Leave them wrapped in foil and double up with a ziplock bag to store for up to three months in the freezer.
