This simple blanched Yu Choy or Choy Sum (菜心, Cài xīn) with garlic sauce is one of the many ways my family loves to enjoy this vegetable.

Have you tried Yu Choy before? I love to call them Choy Sum (Cantonese) which translates to ‘veggie heart’. I always get a bunch of Yu Choy when I see them a the store. It’s my favorite veggie to add to soups, stir-fries, or turn it into a dish by itself.
You may have seen a similar dish like this at Dim Sum restaurants which is normally made with Chinese broccoli or Gai Lan. Yu Choy is a dark leafy vegetable that you commonly see in Chinese cuisines. Today, you’ll see how to use a simple method to cook this vegetable at home – blanch, then slather with a delicious sauce!
I’m using baby Yu Choy in today’s recipe which is usually more tender and takes less time to cook.
How to cook Yu Choy (Choy Sum)
If you are using baby Yu Choy like me, you don’t need to tear it into smaller leaves. However, if you are using normal YuChoy, it’s a good idea to separate the leaf and its stem before cutting them into smaller parts.
Heat up a large then sauté garlic or ginger and chili (if using) in oil until fragrant. Then, add in the store-bought or homemade vegan ‘oyster’ sauce and water. Cook for a few seconds until it starts to thicken. If you are using soy sauce or other sauces that do not contain starch, you may add a cornstarch slurry to thicken the sauce.
Then, fill a wok or tall pot with water and bring it to a boil. Add a drizzle of oil and season the water with a pinch of salt.
When the water comes to a boil, slowly add in the Yuchoy and blanch until the stem turns darker green. (Note: if you are not using baby YuChoy, I would add in the stems first, then the leaves) Dish out and shake off excess water.
Drizzle the sauce on the blanched YuChoy and serve warm. Isn’t it super easy and quick?
