I love having unique recipes like these miso-roasted sweet potatoes because I know dinner won’t be boring. Butter, honey, miso, and seasonings are melted together to create a delicious glaze for the fingerling sweet potatoes to be tossed in. On a baking sheet, the potatoes are roasted until golden and tender.
And, a bonus: the kitchen always smells amazing while they roast!
Fingerling sweet potatoes are a time saver in the kitchen. Because they are small, it’s easier to prep them. The skins are tender, so there’s no need to peel them. They are also easy to slice through. My latest purchase of fingerling-sized sweet potatoes was at the local farmers market.
You can still make this recipe if you can’t find fingerling potatoes! Just buy regular sweet potatoes and cut them into small wedges. Be sure each wedge is similar in size to ensure they bake through in an equivalent timeframe.
Why cook with miso paste?
If you’re a fan of umami flavors, cooking with miso is an easy and delicious way to satisfy your tastebuds. Miso paste can be found in most retail grocery stores. It’s a relatively inexpensive staple lasting up to six months if stored properly. I scoop a little white miso out of the container and return it to the fridge when needed.
Adding miso to sweet potatoes gives you a flavorful combination of sweet, salty, and umami. I use white miso paste for this recipe, which is milder and less salty than its alternate color types (red and yellow). Did you know miso is also categorized by ingredients used during fermentation?
How to Make Miso-Roasted Sweet Potato Fingerlings
Mise En Place (what to prep):
- Sweet Potato Fingerlings – washed, dried, and each cut in half length-wise
- White Miso paste
- Unsalted Butter Ground Ginger
- Garlic Oil (optional) – I used reserved oil from a batch of garlic confit. It’s another good reason to keep this staple in the fridge!
In place of honey, use equal amounts of maple syrup.
Mix in 2 teaspoons of peeled, grated fresh ginger instead of ground ginger.
Garnish with chopped cilantro, chives, or parsley.
Don’t want to use garlic oil? Add 1-2 minced fresh garlic cloves to the melted butter mixture to skip the oil completely. Or whisk in a few cloves of this easy-to-make roasted garlic.
In a microwave-proof container, melt your unsalted butter. Next, whisk in your miso paste, honey, garlic oil, and ginger powder.
Note: If your mixture starts to solidify, pop it back in the microwave for 5 seconds at a time. You want it to melt just enough to coat your potatoes easily, but you don’t want it to burn.
On a sheet pan, toss potatoes with the butter and miso mixture until potatoes are completely coated. Arrange potatoes in a single layer and lightly season with salt and pepper, to taste.
Transfer sheet pan to a 375-degree oven and roast until fork-tender and golden in color.
You can pair these miso-roasted sweet potato fingerlings with several dishes. Here are a few ideas to consider:
- Grilled Chicken
- Pan-Seared Steak
- Roasted Chicken
- Rice Pilaf
- Cheesy Polenta
- Salad Mix
- Roasted Green beans
- Salmon Burgers
What other dishes would you serve them with?
This is a great way to elevate your side dish game. You can’t go wrong with serving these crispy and golden sweet potatoes. The combination of miso, butter, and honey is very tasty and pairs well with the sweetness of the potatoes.
