Grilled Rosemary Sweet Potato Fries

Grilling isn’t just for chicken or steak, my friends. Whether it’s asparagus, corn, bell peppers or sweet potatoes, I love using my handy grill to add smokiness and flavor to all sorts of seasonal vegetables.

Liz Slicing Sweet Potatoes

Most recently, I decided to create one of my favorite side dishes on the grill: sweet potato fries! My husband loves them, my boys love them, we all love them.

Minced Rosemary

For added flavor, I love tossing in minced fresh rosemary that we happen to have growing outside. If you don’t have fresh rosemary, dried works well too!

If you don’t have rosemary, oregano works well too. Feel free to use any of your favorite herbs and spices here.

Seasoning Sweet Potatoes

Next, drizzle with olive oil, salt, cayenne and garlic powder then toss well to coat. Want to make it a little spicy? Add in more cayenne. Want to keep it mild? Skip the cayenne and replace with black pepper.

Making Sweet Potato Packets

Now it’s time to make the foil packets! Simply place the potatoes in the middle of the foil then fold the foil to create little packets to toss on the grill.

Grilling Potatoes Pro Tip:

When grilling the potatoes in foil packets, be sure to leave a little extra room for steam. This will help the potatoes cook all the way through.

Grilling Sweet Potato Packets

Grill for about 16 minutes, flipping around halfway through.

When the potatoes come off the grill they are caramelized, smoky, sweet and tender.

We love serving it with ketchup mixed with Sriracha but they are also just as delicious on their own.

Easy Grilled Sweet Potato Recipe

Can I make these in the oven?

Yes you can follow my recipe for oven baked sweet potato fries.

How far in advance can I prep the foil packets?

You can prep these up to 8 hours in advance.

How much dried rosemary should I use for 2 tablespoons fresh?

As a general rule of thumb, you can replace 1 teaspoon of fresh herbs with 1/2 teaspoon dried. Dried herbs are more potent so you don’t need as many.
