Why You’ll Love This Miso-Glazed Grilled Sweet Potatoes
There are a few things that make this dish special. First, the miso glaze is a tiny powerhouse of flavor: salty, slightly tangy, with a whisper of sweetness that plays beautifully against the natural honeyed notes of sweet potatoes. Second, grilling introduces a comforting char and a smoky depth that you can’t achieve with roasting alone. Finally, the texture is a delight: a soft, creamy center with a caramelized, slightly crisp exterior that holds its shape even when you’re plating and sharing. This dish is also surprisingly versatile, easily doubling as a side or a light main when paired with grains and greens.
Ingredients for Miso-Glazed Grilled Sweet Potatoes
- 4 medium sweet potatoes – peeled and cut into thick wedges; they provide the creamy interior and sturdy bite that grill-friendly textures require.
- 2 tbsp white miso paste – the star of the glaze, offering umami depth and a subtle sweetness.
- 1 tbsp soy sauce – adds savory saltiness that enhances the miso glaze.
- 1 tbsp maple syrup – balances salt with gentle sweetness and helps glaze cling to the surface.
- 1 tsp rice vinegar – a touch of brightness to cut richness and brighten the glaze.
- 1 tsp sesame oil – fragrant nutty note that rounds out the glaze.
- 1 tbsp neutral oil for brushing the potatoes before grilling so they don’t stick and to help the glaze set.
- Toasted sesame seeds for garnish – extra crunch and aroma.
- Thinly sliced scallions for garnish – fresh, mild onion bite that lifts the dish.
- Salt to taste – a pinch to balance flavors if needed.
Step-by-Step Guide to Making Miso-Glazed Grilled Sweet Potatoes
- Preheat your grill or grill pan over medium-high heat and lightly oil the grating to prevent sticking.
- In a small bowl, combine miso paste, soy sauce, maple syrup, rice vinegar, sesame oil, and a pinch of salt. Whisk until smooth and glossy.
- Parboil or microwave the potato wedges for 4–6 minutes to soften the centers without fully cooking through.
- Pat potatoes dry, then toss with a little neutral oil and a light pinch of salt.
- Brush the miso glaze generously on all sides of the wedges.
- Grill the wedges in a single layer, turning occasionally and brushing with more glaze, until deeply caramelized and tender inside, about 8–12 minutes total.
- Remove from grill, transfer to a serving platter, and drizzle with any remaining glaze.
- Garnish with sesame seeds and scallions. Serve warm.

Frequently Asked Questions
Can I use other root vegetables instead of sweet potatoes?
Yes. Yukon gold potatoes or carrot wedges can work, but the cooking time and glaze balance may shift. Sweet potatoes stay the best for a tender interior and a creamy match with miso.
Is this recipe spicy or can I adjust heat?
This glaze is not spicy by default. If you want a little heat, add a pinch of chili flakes or a few drops of sriracha to the glaze and brush on as you grill.
How do I store leftovers?
Store any leftovers in an airtight container in the fridge for up to 2 days. Reheat gently on a grill, in a skillet, or in a warm oven with a light brush of glaze to refresh the shine.
Miso-Glazed Grilled Sweet Potatoes
Ingredients
- 4 medium sweet potatoes, peeled and cut into thick wedges
- 2 tbsp white miso paste
- 1 tbsp soy sauce
- 1 tbsp maple syrup or honey
- 1 tsp rice vinegar
- 1 tsp sesame oil
- 1 tbsp neutral oil for grilling (like canola or grapeseed)
- 1 tbsp toasted sesame seeds, for garnish
- 2 scallions thinly sliced, for garnish
- Pinch to taste salt
Instructions
- Preheat your grill or a grill pan over medium-high heat and lightly brush the grates with oil to prevent sticking.
- In a small bowl, whisk together the miso paste, soy sauce, maple syrup, rice vinegar, sesame oil, and a pinch of salt until you have a smooth, glossy glaze.
- Parboil or microwave the potato wedges for 4–6 minutes until they are just tender but still hold their shape. This helps ensure the centers cook through without burning the glaze.
- Pat the wedges dry with a clean towel. Toss them with a little neutral oil and a pinch of salt to prevent sticking on the grill.
- Brush the miso glaze generously over all sides of the potato wedges. Let them sit for 2–3 minutes to absorb some flavor.
- Grill the wedges in a single layer, turning occasionally and brushing with more glaze, until the outsides are caramelized and slightly charred and the centers are tender, about 8–12 minutes total.
- Transfer to a platter. Drizzle with any remaining glaze, then sprinkle with toasted sesame seeds and sliced scallions.
- Serve warm as a side dish or as a hearty vegetarian main with a grain base like quinoa or brown rice.
