Grilled Baby Potatoes with Dijon Mustard & Herbs

Tested & Perfected Recipes

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

grilled baby potatoes

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


how to make grilled baby potatoes

Begin by cooking the potatoes. Place them in a single layer in a medium saucepan and cover with an inch of water. Bring to a boil, and then simmer for 12 minutes.


To stop the cooking process and quickly cool the potatoes, drain and then run under cold water.


Meanwhile, make the sauce by combining the mayonnaise, Dijon mustard, garlic, thyme, salt, and pepper.


Whisk until smooth.


Gently toss the cooled potatoes with the mustard sauce.


Then grill for about 3 minutes per side, until crisp and slightly charred.


Transfer the potatoes to a serving dish and sprinkle with fresh parsley to add a pop of color, if you like.

Grilled Baby Potatoes with Dijon Mustard & Thyme

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


  • 1 pound baby Yukon Gold potatoes
  • 1/4 cup mayonnaise, best quality such as Hellman's or Duke's
  • 1/4 cup Dijon mustard
  • 1 tablespoon + 1 teaspoon salt
  • 1/4 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)


  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.

  • Wondering what your thoughts were to broil the potatoes under the oven broiler? Do you think this would work? Would be especially convenient in the snowy months if this method would work.

  • Good Evening Jenn! I only have dried thyme/rosemary on hand. Would that work instead of fresh, and if so, how much would I need to substitute? Please let me know? Thank you!

    • Sure, Bethany. I’d recommend just over 1/2 teaspoon of dried thyme or rosemary. Hope you enjoy!

  • These were outrageously good and I loved how you could prep them in advance. Unfortunately they stressed my husband out too much with the sticking and the fiddly turning. Next time I will just broil them, which won’t be quite as good. Still, a stellar recipe, thanks!

  • Have you ever grilled ahead and reheated in microwave or oven? We’re serving them with individual beef fillets for a dinner party and it’d be helpful if we could do ahead. But, we don’t want to mess them up!

  • Hi Jenn, your potatoes are a hit with the kids! Easy to prepare and I used grill pan over the stove as I don’t have an open grill and they are just as good! But I omitted the salt as the seasoning was just perfect as it is.

  • I have tried many recipes from blogs and they never come out good – yet I keep trying. These potatoes were amazing. They are definitely going to be on my table frequently. I enjoyed them so much!
    I also made the strawberry rhubarb crisp (twice) and it was also amazing.

    Thanks so much!

  • I have a bag of regular size Yukon gold potatoes. Can I use them instead of the baby potatoes? If so, is it better to boil the larger potatoes whole or cut them into pieces that are about the same size as baby potatoes?

    • Hi Sarah, I probably boil them whole and then cut them after boiling (they likely will take a few minutes longer on the stove to get tender. Hope you enjoy!

    Beautiful flavor for summer, especially with fresh herbs from the garden.
