My husband, Michael makes these grilled baby potatoes whenever we have people over for a cookout. (READ: they’re easy!) The thick Dijon mustard marinade gives them a crispy texture and bold flavor. The key to grilled potatoes is to fully cook the potatoes before they ever hit the grill. Yes, it does add an extra step but it’s worth it, especially if you’re entertaining.

By boiling the potatoes first, you can get most of the recipe done ahead of time. And, more importantly, you can ensure that the potatoes are perfectly cooked — not charred on the outside and raw on the inside.

What you’ll need to make grilled baby potatoes

Potato ingredients including mayonnaise, Dijon mustard, and sea salt.

A thick Dijon mustard marinade gives these grilled baby potatoes great texture and flavor. Perfect for a summer cookout!

Servings: 4-6
Total Time: 35 Minutes

Ingredients

  • 1 pound baby Yukon Gold potatoes
  • ¼ cup mayonnaise, best quality such as Hellman's or Duke's
  • ¼ cup Dijon mustard
  • 1 tablespoon + 1 teaspoon salt
  • ¼ teaspoon freshly ground black pepper
  • 3 cloves garlic, minced
  • 2 teaspoons chopped fresh thyme (rosemary would also work well, or a combination)
  • 1 tablespoon chopped fresh Italian parsley, for garnish (optional)

Instructions

  1. Place the potatoes in a medium pot; add water to cover by 1 inch and 1 tablespoon of the salt. Bring to a boil over high heat; reduce the heat and simmer until the potatoes are tender when pierced with a sharp knife, about 12 minutes. Drain the potatoes; then place them back in the pan and run under cold water to cool.
  2. Preheat the grill to medium-high heat.
  3. In a large bowl, whisk together the mayonnaise, the Dijon mustard, remaining teaspoon salt, pepper, garlic and thyme.
  4. Drain the potatoes and slice them in half. Add to the Dijon mustard sauce and toss to coat evenly, taking care not to smash the potatoes.
  5. Clean and oil the grill grate. Place the potatoes on the grill and cook, covered, for about 3 minutes, or until you see nice grill marks on the first side. Using tongs, turn the potatoes and grill about 3 minutes more, until crisp and golden all over. Transfer the potatoes to a serving platter and sprinkle with chopped parsley (if using).
  6. Note: Potatoes can be boiled 1 day ahead of time. Bring to room temperature before grilling.

  • Hi Jenn, Can I cook the potatoes and put the marinade on them and then stick them in the fridge for a few hours before grilling or is it best to do it right before?

    • Sure, Sarah – that’s fine.

  • Loved the flavour but my potato’s did not get crispy and seared. Bar-b-que not hot enough? Any suggestions for temp?

    • Hi Elaine, It does sound like your grill wasn’t hot enough. The grill should be set to medium-high which is the equivalent of 400 – 450 F (204 – 232 C). Also, the grill should be covered. Hope that helps!

      • Appreciate all the great recipes and help with any questions!

        • My pleasure! 🙂

  • These Potatoes were delicious! perfectly seasoned and anything with dijon mustard count me in! Family loved it too 🙂

  • This recipe was as good as I hoped it would be! I’ve cooked it for all ages, and it’s a hit with everyone!

  • I would love to try to this recipe ! But I don’t have an outdoor grill is there a substitute ?

    • Hi Jerrika, You can make them in the oven; use the broil setting and place them on a broiling rack. Hope you enjoy!

      • Should the broiler be set to hi or low? Thank you!

        • High 🙂

  • These potatoes were so good! They were really easy. I didn’t find them too salty at all. I used kosher salt, not sure if that was what was intended. Always looking for new ways to enjoy potatoes and this recipe is definitely a keeper. I used rosemary instead of thyme because that is what I had.

  • These were so easy and super delicious. My 7 year old absolutely loved them. I added extra garlic because we love garlic, but otherwise followed as directed. I didn’t mind the “extra” step of boiling because I find potatoes can cook unevenly on the BBQ so I am always worried that someone is going to end up with a mouthful of raw potato, but this method makes sure that doesn’t happen.

  • Should u cut the potatoes in half after boiling them? Thanks!

    • Yep– hope you enjoy!

  • Is this recipe gluten free?

    • Yes! If you’re looking for more gluten-free recipes on the blog, you can find them here.

  • This is just what I was looking for; a tasty way to make potatoes on the grill. The Dijon mustard gives a nice zip and I added extra Rosemary because I love it with potatoes. The only thing I will do differently next time will be to cut the salt to about 1/2 tsp because everyone said it was great but a little salty.
