These grilled potatoes with red miso butter offer a sophisticated twist on a classic barbecue side dish. By parboiling the baby potatoes in salted water before hitting the grill, you ensure a fluffy interior that contrasts beautifully with the smoky, charred skins. The star of the show is the rich, umami-heavy glaze, which combines creamy unsalted butter with the deep, fermented notes of red miso and a bright splash of rice vinegar.
This vegetarian dish is an excellent addition to any summer spread, providing a savoury depth that pairs perfectly with grilled vegetables or halloumi skewers. Using a cast-iron frying pan directly on the grill allows the garlic and miso to infuse without burning, creating a glossy sauce that clings to every crinkle of the crushed potatoes. Finish with a generous handful of fresh parsley for a burst of colour and herbal freshness.

How to make Grilled Potatoes With Red Miso Butter
Back to contentsPrepare a grill for medium-high heat. Bring potatoes, salt, and 0.9L water to a boil in a medium saucepan over medium-high heat. Reduce heat and simmer until tender, 12–14 minutes; drain. Grill potatoes, turning often with tongs, until lightly charred, 6–8 minutes.
Meanwhile, set a medium skillet, preferably cast iron, on grill. Place butter and miso in skillet and cook, stirring, until butter is melted and mixture is smooth, about 2 minutes. Remove from heat; stir in garlic and vinegar. Season with pepper.
Transfer potatoes to skillet, breaking some in half with tongs. Toss to coat in miso butter. Add parsley; toss again.
