Mashed japanese sweet potatoes
This mash takes one humble Japanese sweet potato and turns it into something luxurious. Simmering it in vegetable broth infuses it with depth and a quiet savoriness that balances its natural sweetness. Once whipped with butter and cream, the texture becomes silky and cloud-soft; the kind of mash that makes even simple dinners feel intentional. It's a small, thoughtful side dish with big flavor, perfect alongside roasted chicken, vegetables, or anything that needs a touch of cozy.
Ingredients
1 large Japanese (Murasaki) sweet potato, about ¾–1 lb
Vegetable broth, enough to cover in the pot
1 tbsp unsalted butter
2–3 tbsp heavy cream or whole milk
Kosher salt
Optional splash of reserved broth (1–2 tsp) for loosening
Instructions

Peel the potato, cut it into chunks, and place it in a pot. Cover fully with vegetable broth and add a pinch of salt.
Bring to a boil, then reduce to medium-low and simmer until fork-tender, 12–15 minutes.Drain:
Drain the sweet potato through a colander and let it rest 2–3 minutes so excess moisture evaporates.Mash:
Return the potato to the pot. Add butter, cream, and a generous pinch of salt.Whip:
Use an electric hand mixer (or whisk) to whip until smooth and fluffy.
If needed, add 1–2 tsp reserved broth to adjust texture.Taste & finish:
Add more salt, cream, or butter to your liking. Serve warm.
Tips & Substitutions
Dairy-free option: Use olive oil or coconut milk (a little goes a long way).
Add warmth: Fold in a pinch of cinnamon, nutmeg, smoked paprika, or your curry blend.
Make it savory-leaning: Add a spoon of caramelized onions or roasted garlic.
Texture tip: Japanese sweet potatoes are denser — the broth addition at the end helps keep the mash silky.
