Miso Glazed Sweet Potatoes

These Miso Glazed Melting Sweet Potatoes transform humble sweet potatoes into a culinary masterpiece with a perfect balance of sweet and savory flavors. The Japanese sweet potatoes become incredibly tender in the center while developing a caramelized exterior that soaks up the umami-rich glaze.

I discovered this recipe when looking for a way to elevate sweet potatoes beyond the typical marshmallow-topped casserole. Now my family requests these "melting potatoes" nearly every holiday dinner, and I've caught guests secretly swiping the last pieces when they think no one is watching.

Ingredients

• Japanese sweet potatoes: These have a drier texture and sweeter flavor than orange varieties which makes them perfect for caramelizing
• Avocado oil: Has a high smoke point ideal for the initial sear without burning
• White miso paste: Provides the umami backbone of the glaze and creates complex flavor with minimal effort
• Maple syrup: Balances the saltiness of the miso with natural sweetness better than regular sugar
• Butter: Creates richness and helps the glaze cling to the potatoes
• Flaky sea salt: The finishing touch that enhances all the flavors and adds textural contrast

Step-by-Step Instructions

Prepare the sweet potatoes:

Peel the Japanese sweet potatoes completely and slice them into uniform 1-inch rounds. Consistency in thickness ensures they'll cook evenly and achieve that perfect melting texture throughout.

Create the miso glaze:

Whisk the white miso paste and maple syrup together in a small bowl. Gradually add the water bit by bit while whisking constantly until you have a smooth mixture without any miso lumps. This gradual approach prevents clumping and ensures a silky glaze.

Sear the sweet potatoes:

Heat your heaviest oven-safe skillet over medium-high heat. Add avocado oil and wait until it shimmers across the surface. Arrange the sweet potato rounds in a single layer without crowding and sear for 3 to 4 minutes without disturbing them. This develops a deep golden crust and complex flavor. Use tongs to flip each round carefully and sear the second side for 1 to 2 minutes.

Add the butter and glaze:

Turn off the heat and add the butter to the hot skillet. Swirl the pan gently as the butter melts to coat the bottom. Pour the miso mixture over everything and use tongs to lift each potato slice slightly so the sauce flows underneath. This ensures the flavor penetrates from all sides.

Oven finish the potatoes:

Transfer the entire skillet to your preheated oven. After 15 minutes of baking use oven mitts to carefully remove the skillet and baste the potatoes with the sauce that has now begun to thicken and caramelize. Return to the oven for another 5 to 10 minutes until the potatoes yield easily when pierced with a fork but still hold their shape.

Serve with flair:

Transfer the finished sweet potatoes to a serving plate or platter. Pour all the remaining glaze from the pan over the top making sure to scrape up any caramelized bits from the bottom of the skillet. Finish with a generous sprinkle of flaky sea salt just before serving.

Pin it

White miso paste is my secret weapon in this recipe. Its gentle fermented flavor brings depth that most people can’t quite identify but absolutely love. The first time I served these at Thanksgiving my brother-in-law who claims to hate sweet potatoes ate three servings before asking what made them so addictive.

Make Ahead Magic

These sweet potatoes can be partially prepared in advance to save time on busy days. Complete the searing step then cool and refrigerate the potatoes. When ready to serve prepare the miso glaze fresh and continue from the oven step adding about 5 extra minutes to the cooking time since you’re starting with cold potatoes. The glaze won’t be quite as thick when made this way but the flavor remains outstanding.

Substitution Possibilities

If you can’t find Japanese sweet potatoes regular orange varieties work well too though they will be slightly moister and less dense. For a dairy-free version substitute coconut oil or olive oil for the butter. Red miso can replace white miso for a stronger more robust flavor profile but reduce the amount by about 25% to prevent overpowering the dish. Honey makes a good substitute for maple syrup though it will change the flavor profile slightly.

Serving Suggestions

While perfect on their own these miso glazed sweet potatoes pair beautifully with grilled or roasted meats especially pork tenderloin or roast chicken. They complement grain bowls wonderfully and make an unexpected but delicious side for holiday meals. For a stunning appetizer serve smaller portions on individual spoons with a tiny sprinkle of toasted sesame seeds. I often serve them alongside a simple green salad with a bright vinaigrette for a satisfying light dinner.

Cultural Context

This recipe beautifully bridges Japanese and Western culinary traditions. Miso has been a staple in Japanese cooking for centuries prized for its complex umami properties. When combined with the natural sweetness of sweet potatoes and the richness of maple syrup it creates a fusion dish that honors both cultures while creating something entirely new and craveable.

The miso paste adds a savory umami flavor that balances the sweetness of the potatoes and maple syrup.

→ How do I prevent the glaze from burning?

Ensure the heat is properly adjusted during searing, and keep an eye on the skillet to avoid overheating the miso mixture.
