Holly’s Recipe Highlights

  • Flavor: Buttery and creamy, with a hint of rosemary, grilled red potatoes make a tasty summer side. 
  • Skill Level: Very easy! This recipe is perfect for beginner grillers.
  • Swaps: No grill? No problem! Oven-roast potato packets at 375°F until cooked through.
  • Time-Saving Tip: Pre-cooking potatoes in the microwave shaves off major minutes before grilling them. You can also slice and season potatoes up to a day in advance, then grill just before serving.
  • Serving Suggestions: Serve with BBQ chicken, burgers, or shrimp kabobs

Ingredient Tips for Grilled Potatoes

Potatoes: Thin-skinned red potatoes (or baby potatoes) don’t need peeling and have a creamy texture once cooked. Yukon golds, white or russet potatoes, or fingerlings will all work. Peeling is optional; leave them unpeeled for a more rustic look.

Seasonings: Butter, garlic, and fresh rosemary add subtle flavor to grilled potatoes, but you can experiment with seasonings that match the menu, like an adobo blend to go with grilled chicken fajitas or a Cajun seasoning to go with sausage and veggie foil packs.

Variations

  • In addition to the onion, feel free to toss in other veggies like sliced carrots, mushrooms, bell peppers, or cabbage wedges.
  • Try using a few tablespoons of olive oil in addition to or in place of butter.
  • Sprinkle finished potatoes with parmesan cheese, bacon bits, or green onions.
  • Try other fresh herbs like dill, chives, or cilantro.

Holly’s Pro Tips for Perfect Potatoes

  • Use heavy-duty aluminum foil to avoid tears or sticking.
  • Potatoes, onions, and any other veggies (if using) should be cut evenly so everything cooks uniformly.
  • Sealing the edges tightly will prevent all those savory juices from leaking out.
  • Try opening the foil halfway through for crisper edges.

Leftover Potatoes?

Keep leftover grilled potatoes in an airtight container in the refrigerator for up to 4 days or freeze them in zippered bags for up to 2 months.

Reheat leftovers in a frying pan, the air fryer, or in the oven. They’re great added to a chorizo breakfast hash, or in a soup or stew.

Ingredients  

  • 3 pounds red potatoes
  • 1 small onion sliced
  • ¼ cup butter cubed, more to taste
  • 3-4 cloves garlic sliced
  • 2 teaspoons fresh rosemary chopped, or ½ teaspoon dried and slightly crushed
  • salt and black pepper to taste

Instructions 

  • Wash potatoes and cut into bite size pieces. Place in a microwave safe bowl and cover tightly with plastic wrap. Microwave for 3-4 minutes or just until fork tender.
  • Preheat grill to medium-high heat.
  • Add rosemary, salt, and pepper to the potatoes. Toss to coat.
  • Lay out a sheet of heavy duty aluminum foil approximately 2 feet in length. Spray with cooking spray.
  • Add the potatoes, onions & garlic on one half of the foil and top with butter. Fold the other half of the foil over top. Roll the edges of the foil on all sides to create a tight seal.
  • Place the potatoes on the grill and cook 25-30 minutes, turning occasionally. Cook until the potatoes are tender and golden brown.
  • Serve warm with sour cream or desired toppings.

Notes

  • Cook the potatoes part way by placing them in the microwave or boiling just until fork tender. This keeps the grill time short. If microwaving, no water is needed.
  • Use heavy-duty foil for the best results.
  • Other vegetables can be added to the mixture.
  • Potatoes can be skewered and cooked directly on the grill over indirect heat if you’d prefer. If using wood skewers, be sure to soak them in water for 30 minutes before grilling.
  • This potato foil packet recipe can also be cooked in the oven at 400°F. Bake for about 30 minutes.
  • Garnish with parsley and serve with sour cream or homemade ranch for dipping.
