The Murasaki (or Japanese sweet potato) is not your average sweet potato. With a deep purple skin and delicate cream-colored interior, a Murasaki sweet potato offers a beautiful contrast on the plate. Its firm texture holds up well to slow roasting, baking, or steaming, acquiring a smooth, buttery bite with a subtle, hearty chestnut-like flavor.
Murasaki’s are the perfect potatoes for both sweet and savory flavors to truly stand out. This variety offers a more balanced, earthy sweetness that pairs beautifully with butter, salt, and herbs. This simple baked Murasaki sweet potato method is a fan-favorite, making it easy to enjoy the natural flavor with minimal effort.
For this baked Murasaki sweet potato recipe, you’ll need:
Optional Add-ins:
Preheat your oven to 425°F.
Wash the Murasaki sweet potatoes thoroughly to remove any dirt, then dry them completely with a towel. Using a fork or knife, pierce each potato a few times to allow steam to escape while baking.
Place the potatoes on a baking sheet lined with parchment paper or foil, or baking tray lined with a wire rack. Lightly rub the outside of each potato with olive oil or melted butter, making sure they are evenly coated.
Wrapping the potatoes in foil is up to preference: Wrapping in foil causes the Murasaki skins to steam and soften. Baking the potatoes bare gets you lightly crisp skins.
Place the potatoes in the oven and bake for 45-60 minutes.
After 30 minutes, turn the potatoes over to ensure even cooking. Continue baking for the remaining 15-30 minutes, depending on their size. More time may be needed if your potato is of the larger crop!
You’ll know they’re done when the skins are slightly crisp, the inside feels very soft when gently squeezed, and a knife easily slides through the center.
Remove the potatoes from the oven and let them rest for a few minutes.
Slice them open lengthwise and gently fluff the interior with a fork. Add a small pat of butter if desired, allowing it to melt into the warm, creamy center.
Finish with a sprinkle of flaky salt, pepper, and fresh herbs for a simple but flavorful touch.
Serve warm and enjoy!
These additional ingredients pair well with Murasaki’s to satisfy whatever taste you’re after!
Butter & Honey: A drizzle of honey with melted butter enhances their natural sweetness.
Savory Herb: Add garlic butter and fresh thyme or rosemary for a more savory profile.
Cheesy & Creamy: Soft cheeses like Butterkäse, Brie, or Havarti melt down and pair perfectly with the potato’s creamy texture.
Spiced: Sprinkle with cinnamon or smoked paprika for a subtle twist.
Slow baking brings out the best in Murasaki sweet potatoes—deep flavor, creamy texture, and a perfectly balanced sweetness that feels both comforting and elevated. However, Murasaki’s are more versatile than you may think! Here are some more tasty recipes to try with your sweets:

Sweet Potato Grain Bowls: Cube and roast, then add to bowls with quinoa or rice, roasted vegetables, greens, and a tahini or miso dressing.
Sweet Potato Salad: Roast the potato diced in cubes and toss with arugula, goat cheese, nuts, and a light vinaigrette for a balanced, slightly sweet salad.
