Choy Sum in Oyster Sauce: A Taste of Home

My grandmother, a whirlwind in the kitchen, always had a pot of something fragrant simmering on the stove. While her repertoire spanned countless dishes, I distinctly remember the vibrant green of her choy sum, glistening with a savory, umami-rich sauce. It wasn’t just a side dish; it was a symbol of her love, a reminder of her heritage, and a comforting taste of home that I carry with me always. Every time I prepare this simple yet elegant dish, I’m transported back to her bustling kitchen, filled with warmth and the delicious aroma of Cantonese cooking.

Recipe Overview

Prep Time: 5 minutes
Cook Time: 5 minutes
Total Time: 10 minutes
Servings: 4-6
Dietary Type: Not Vegetarian/Vegan

Ingredients

300 g choy sum
1 tablespoon vegetable oil
1 teaspoon garlic, finely chopped
1 tablespoon oyster sauce

Equipment Needed

Large pan
Wok or deep pan

Instructions

Begin by preparing the choy sum. Bring a large pan of water to a rolling boil.
Once boiling, blanch the choy sum in the boiling water for approximately 30 seconds. This quick blanching helps to retain the vibrant green color and tender-crisp texture of the vegetable.
Immediately drain the choy sum thoroughly and set it aside. This prevents overcooking.
Next, prepare your wok or deep pan. Place it over medium-high heat until it’s properly preheated. A hot wok is essential for achieving that characteristic wok hei, or “breath of the wok,” a smoky, slightly charred flavor.
Add 1 tablespoon of vegetable oil to the preheated wok or deep pan. Ensure the oil is heated before adding the garlic.
Add 1 teaspoon of finely chopped garlic to the hot oil. Stir-fry the garlic until it becomes fragrant, being careful not to burn it. Burnt garlic will impart a bitter taste to the dish. This should take only a few seconds.
Add the blanched choy sum to the wok or deep pan. Toss the choy sum continuously for about 1 minute, ensuring it’s evenly coated with the oil and garlic.
Now, add 1 tablespoon of oyster sauce to the wok. Stir the oyster sauce into the choy sum, making sure it’s well combined and coats all the vegetables.
Continue to toss and cook for another minute or so, until the choy sum is heated through and the sauce has slightly thickened.
Serve immediately.

Expert Tips & Tricks

Don’t overcook the choy sum! The key to delicious choy sum is maintaining a tender-crisp texture. Overcooking will result in a mushy and less appealing dish.
High heat is your friend. Using high heat ensures the choy sum cooks quickly and retains its vibrant color. It also helps to create that desirable “wok hei” flavor.
Adjust the oyster sauce to your liking. Some oyster sauces are saltier than others, so taste and adjust the amount accordingly. You can also add a touch of sugar to balance the flavors.
Ginger boost: For an extra layer of flavor, consider adding a small amount of finely grated ginger along with the garlic.
Prep is key: Having all your ingredients prepared and ready to go before you start cooking will make the process much smoother and faster. Chop the garlic and measure the oyster sauce beforehand.
For a richer flavor, use a high-quality oyster sauce. The difference in taste is noticeable.

Serving & Storage Suggestions

Serve the choy sum in oyster sauce immediately while it’s hot and the vegetables are still crisp. It makes an excellent side dish to accompany any Chinese meal, particularly roasted meats, steamed fish, or stir-fried noodles.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, you can microwave it briefly or stir-fry it in a wok or pan until heated through. Note that the texture may be slightly softer after reheating.

I don’t recommend freezing this dish, as the choy sum will lose its texture and become watery upon thawing.

Variations & Substitutions

Vegetarian Option: While traditional oyster sauce contains oyster extracts, you can substitute it with vegetarian oyster sauce, which is made from mushrooms.
Garlic Lover’s Version: Double the amount of garlic for a more intense garlic flavor.
Spicy Kick: Add a pinch of red pepper flakes or a thinly sliced chili pepper to the oil along with the garlic for a spicy twist.
Soy Sauce Substitute: If you don’t have oyster sauce, you can use a combination of soy sauce (1/2 tablespoon) and a touch of sugar (1/4 teaspoon). However, the flavor will be different.
Broccoli or Gai Lan: You can use broccoli or gai lan (Chinese broccoli) as a substitute for choy sum, adjusting the blanching time accordingly.
