🥘 Why This Recipe Works
奶油馬鈴薯 (nǎi yóu mǎ líng shǔ) — literally “butter potato” — looks humble but hides a clever two-step technique: the potatoes are steamed first until fluffy, then pan-fried in butter until the surface turns a golden, crispy 恰恰 (qià qià). Steaming means the insides stay cloud-soft while the butter does the caramelizing on the outside — you get a crispy shell and a melting center without deep-frying anything.
The magic doesn’t stop at the potatoes. Hand-torn king oyster mushroom (杏鮑菇) brings a fibrous, almost meaty bite, while bunapi mushrooms (鴻喜菇) add earthy depth. Everything gets fried in butter until deeply browned, then tossed with curry powder, oregano, white and black pepper, and finished with a handful of Thai basil (九層塔) over high heat. In Qistin Wong’s video, the aroma alone pulls her kids out of their homework — that’s the power of butter and basil.
This version: 11 ingredients, one pan, 25 minutes. Fully vegan when you use plant-based butter — a perfect weeknight side, bento box companion, or afternoon snack.
🛒 Ingredients
| Potatoes (馬鈴薯) | 2–3 medium (~500g) | Cut into bite-size chunks; peel optional |
| King oyster mushroom (杏鮑菇) | 1 stalk (~150g) | Tear into chunks by hand for a fibrous bite |
| Bunapi / shimeji mushrooms (鴻喜菇) | ½ pack (~100g) | Separate into individual stems |
| Thai basil (九層塔) | ½ bunch | Leaves only; can swap for cilantro or celery |
| Vegan butter (純素奶油) | 1 tbsp + 1 small piece | The extra piece is for frying the mushrooms |
| Cooking oil (食用油) | 1 tsp | Mixed with butter so it doesn’t burn |
| Salt (鹽) | 1 tsp | Adjust to taste |
| White pepper (白胡椒粉) | ½ tsp | Classic Chinese pantry spice |
| Black pepper (黑胡椒) | ¼ tsp | Freshly ground if you have it |
| Curry powder (咖哩粉) | ½ tsp, or to taste | Warm, golden aroma |
| Oregano (俄力岡粉) | ½ tsp, or to taste | Dried oregano adds a herby lift |
👨🍳 Instructions
Step 1: Steam the Potatoes
- Cut the potatoes into chunks — halve, then halve again, so every piece is roughly the same size.
- Steam in a rice cooker or electric steamer until a fork slides in easily, about 15 minutes.
- Shake off any pooled water before frying so the potatoes aren’t soggy.
Step 2: Prep the Mushrooms & Basil
- Tear the king oyster mushroom into rough chunks the same size as the potatoes — tearing, not cutting, gives a meaty texture.
- Separate the bunapi mushroom stems and rinse them briefly.
- Pick the Thai basil leaves off the stems and set them aside.
Step 3: Pan-Fry the Potatoes
- Melt 1 tablespoon of butter with a splash of cooking oil in a wide pan over medium-low heat — the oil stops the butter from burning.
- Add the steamed potatoes in a single layer and fry, turning occasionally, until golden and crispy on all sides, about 5 minutes.
- Scoop the potatoes out onto a plate and set aside.
Step 4: Fry the Mushrooms
- Add the small piece of butter to the same pan and tip in all the mushrooms.
- Fry until browned and fragrant, about 2 minutes — the deeper the color, the richer the aroma.
- Return the crispy potatoes to the pan.
Step 5: Season & Finish
- Season with salt, white pepper, black pepper, curry powder, and oregano; toss until every piece is coated.
- Add the Thai basil and stir-fry over high heat until the leaves just soften, about 30 seconds.
- Serve immediately — it’s best hot and crispy.
💡 Tips & Substitutions
| Butter burns quickly in the pan | Mix in a splash of neutral cooking oil — it raises the smoke point and keeps the butter golden. |
| No vegan butter on hand? | Use coconut oil or olive oil instead. The flavor shifts a little, but the crispy texture stays. |
| Don’t like Thai basil? | Qistin Wong suggests cilantro (香菜) or celery (芹菜) — both add their own fresh kick at the end. |
| Potatoes take forever to brown | That’s why we steam first — the surface only needs a few minutes of butter-frying to turn 恰恰 crispy. |
| Want it even more aromatic? | Fry the mushrooms a little longer until deep golden-brown; more color means more umami. |

Notes
🌱 Why This Dish
The Chinese name 奶油馬鈴薯 (nǎi yóu mǎ líng shǔ) pairs 奶油, “cream butter,” with 馬鈴薯, the classical name for the potato — literally “horse-bell tuber,” a nod to the vegetable’s shape; in northern China it’s more commonly called 土豆 (tǔ dòu, “earth bean”). Butter-fried potatoes are a Western-influenced home dish that Chinese cooks embraced for one simple reason: the technique is forgiving, the ingredients are cheap, and children adore them — in Qistin Wong’s video, her kids literally leave their homework to come taste it.
In Chinese Buddhist vegetarian kitchens (素食齋堂), the dish takes on a special meaning. Temple cooks traditionally avoid the “five pungent” vegetables and animal products, so butter is swapped for plant-based 純素奶油 and the meal becomes fully 純素 (pure vegan) — rich enough to feel indulgent, yet completely meatless and suitable for offering tables at festivals and 初一十五 (the first and fifteenth of the lunar month). It’s equally at home as a 家常菜 (family home dish), a 便當配菜 (bento side dish), or an afternoon snack — proof that vegan cooking doesn’t have to sacrifice comfort.
And that final handful of 九層塔 (jiǔ céng tǎ) — “nine-story pagoda,” so named because the basil plant grows in layered tiers like a pagoda — is a signature Taiwanese touch, adding a peppery, anise-like perfume that ties the whole pan together.
