Vegan Miso-Glazed Sweet Potatoes
Sweet potatoes are halved, roasted until tender, then brushed with a glaze of white miso, maple syrup, and sesame oil and broiled until lightly charred at the edges. The result balances umami depth with natural caramel sweetness in a dish that takes about 45 minutes start to finish. Serve as a side or a light main alongside steamed rice or greens.

Ingredients
For the Miso-Glazed Sweet Potatoes:
- 2 lb sweet potatoes preferably garnet or Japanese satsumaimo; scrubbed, dried, and cut into 1-inch wedges
- 1 tbsp neutral oil avocado or grapeseed for high heat
- ½ tsp kosher salt Diamond Crystal preferred
- ¼ tsp freshly ground black pepper
For the Miso Maple Glaze:
- 3 tbsp white miso paste (shiro miso) look for organic brands like Hikari or Miso Master
- 2 tbsp pure maple syrup grade A amber for balanced sweetness
- 1 tbsp unseasoned rice vinegar seasoned vinegar contains sugar/salt; use unseasoned
- 1 tbsp low-sodium tamari or soy sauce use tamari for gluten-free
- 1 tsp toasted sesame oil adds nutty aroma; a little goes a long way
- 1 tsp fresh ginger, finely grated use a Microplane for a silky paste
- 1 clove garlic, finely grated about 1/2 tsp when grated
- ¼ tsp red pepper flakes optional, or use 1/2 tsp gochugaru for a gentler heat
- 2 tbsp water to thin the glaze to brushable consistency
To Finish & Garnish:
- 1 tsp toasted white sesame seeds
- 1 tsp toasted black sesame seeds
- 2 whole scallions, thinly sliced on the bias
- 1 medium lime, cut into wedges optional, for brightness at the table
- 1 tbsp shredded nori optional, for oceanic umami and texture
- ¼ cup microgreens or cilantro leaves optional, for fresh contrast
Instructions
- Heat the Oven: Preheat to 425°F (220°C). Line a rimmed baking sheet with parchment or a silicone mat for easy release and even browning.
- Prep the Potatoes: Cut scrubbed sweet potatoes into 1-inch wedges. Pat dry thoroughly—dry surfaces caramelize better. Toss in a large bowl with neutral oil, kosher salt, and black pepper until each wedge has a light, even sheen.
- Roast for Color and Tenderness: Arrange wedges cut-side down with a little space between pieces. Roast for 15 minutes, then flip with tongs. Continue roasting 8–10 minutes, until edges are deeply golden and the centers are just tender when pierced (you should smell a warm, caramel aroma).
- Make the Glaze while Roasting: In a small saucepan, whisk miso, maple, rice vinegar, tamari, sesame oil, ginger, garlic, red pepper flakes, and water until smooth. Warm gently over low heat for 2–3 minutes until glossy and slightly thickened; avoid boiling to preserve miso’s delicate aromatics. No saucepan? Whisk in a bowl, using hot tap water to help dissolve the miso.
- Glaze and Broil: Switch the oven to broil (high). Brush a generous layer of glaze over the hot potatoes. Broil 2–3 minutes until the glaze bubbles and lightly chars in spots (watch closely to prevent burning). No broiler? Return to 425°F (220°C) for about 5 minutes instead.
- Finish: Transfer potatoes to a warm platter. Drizzle with any remaining glaze (or reserve a tablespoon for the plate), then shower with white and black sesame seeds and scallions. Add a squeeze of lime at the table for brightness.
- Serve: Present immediately while the edges are crisp and the glaze is tacky and aromatic with miso, maple, and toasted sesame.
Notes
Michelle’s Tips:
- Maximize Crisp Edges: Preheat the baking sheet in the oven for 5 minutes; add the oiled wedges to the hot pan for instant sizzle.
- Don’t Crowd: Space wedges so steam can escape. Overcrowding leads to soft, pale potatoes.
- Smoother Glaze: Whisk miso with a spoon of warm water first to form a slurry, then add remaining liquids for a lump-free finish.
- Flavor Swaps: Try red miso for a deeper, saltier note (reduce tamari to 2 tsp). Swap maple with agave or brown rice syrup for a different sweetness profile.
- Heat Level: Replace red pepper flakes with a pinch of shichimi togarashi for citrusy heat and sesame fragrance.
- Gluten-Free Assurance: Use certified gluten-free tamari and check miso labels.
- Air Fryer Method: 400°F (205°C) for 15–18 minutes, shake halfway; brush with glaze and air-fry 1–2 minutes more to set.
