Summertime makes me happy! Whether we’re hanging out on the patio grilling turkey burgers, veggie kabobs or chicken parmesan sliders, it’s my warm time happy place.

Oh, and have you ever grilled romaine lettuce? It makes for a killer chicken caesar salad! But that’s for another bbq day.

Back to these homemade sweet potatoes on the grill….They’re basically like making sweet potato fries, but better!

Y’all, these are so GOOD and so SIMPLE!

How to Make Sweet Potato Wedges on the Grill

Grilling sweet potatoes is a little different than grilled sweet corn or asparagus.

There’s a tiny bit of prep involved, but don’t let this scare you.

Basically, we’re giving our healthy sweet potatoes a jump start with a little bath in some simmering water. This helps the sweet potatoes to start cooking before they go on the grill.

Why do we boil the whole sweet potatoes before we grill them? Because crunchy raw potatoes are not a good thing, my friends.

Cook them in boiling water for about 8-10 minutes, until they’re fork tender but not entirely cooked. We don’t want them falling apart on the grill.

Drain the potatoes and let them cool.

Do you eat the sweet potato skins or remove them? That, my friend, it totally up to you. I will say that it’s less work to leave the skins on, plus they contain fiber and potassium, so that’s a double win! Here are more sweet potato nutrition facts.

Cut each sweet potato into 4 wedges, the long way. You can cut them into six wedges if they are those monstrous big sweet potatoes.

Preheat grill to medium heat. Place potato wedges on the grill and cook, turning once or twice until potatoes are cooked through, about 10 minutes.

Then, we remove these bad boys from the grill and put them into a large bowl. Toss with a little bit of melted butter and season with salt and BBQ seasoning, if desired. That’ll get you the awesome taste of a bbq baked sweet potato fry.

What to Pair With Grilled Sweet Potato Wedges

Since your grill is already heated up, why not pair your grilled baked sweet potatoes with a Baja Burger (ground beef, seasoning, avocado and cheese – yum!), chicken parmesan sliders, or honey dijon turkey burgers.

And while you’re at it, throw some pineapple slices on the grill. They’re easy, delicious and a good pairing to the sweet potatoes!

How to Make Smoky Mayo Sauce for Grilled Sweet Potato Fries

Making the dipping sauce for your sweet potato fries couldn’t be any easier!

Mix mayo and your favorite BBQ sauce. Add a drop or two of liquid smoke and stir well to combine.

I recommend you go easy on the liquid smoke. If it’s less than 1/8 tsp that’s better than more. Yep, this is one case where less is more! It’s pretty concentrated in flavor but it adds an awesome smoky taste and depth of flavor!

How to switch up your roasted sweet potato fries

  • Vary the bbq seasoning or type of seasoning you use. Rosemary sweet potatoes would be a perfect blend!
  • Switch the butter out for olive oil. It doesn’t take much, it’s basically there to hold the seasonings in place!
  • Change up the dipping sauce. Sriracha mayo anyone??
  • You can bake your sweet potatoes in the Instant Pot for a few minutes instead of boiling them for quick roasted sweet potatoes. Just don’t overdo it!
