Why It Works

Quickly blanching the lettuce coaxes out its mild sweetness and softens the leaves while preserving a subtle crunch.
A cornstarch-thickened oyster sauce mixture clings to each leaf, delivering deep umami flavor without overwhelming the delicate greens.

For as long as I can remember, lettuce with oyster sauce has been a staple in my family's kitchen. The dish is quick to prepare yet deeply flavorful, thanks to rich, savory, and sweet oyster sauce balanced with soy sauce, garlic, and a hint of sugar. With just a few pantry staples and a head of crisp lettuce, you can have a vibrant, tasty side dish on the table in minutes. Whenever I feel homesick but can't make the long drive to an Asian grocery store to pick up gai lan (Chinese broccoli) or tender Shanghai bok choy, I turn to this dish. It's comforting and dependable, and made with ingredients that most American grocery stores keep in stock.

Blanching Transforms Lettuce

Lettuce is usually eaten raw in the West, but that doesn't mean it's never cooked: Grilled romaine Caesar salads, braised lettuce, wilted greens with warm bacon dressing are just a few examples. Though the Chinese approach—in which lettuce is quickly blanched and topped with a savory oyster sauce—is a less familiar method of preparing the vegetable in the West, it's no less rewarding, and is how many Chinese families prepare lettuce at home.

Blanching transforms lettuce completely, enhancing the vegetable's sweetness and softening the leaves while leaving behind a subtle crunch. The glossy oyster sauce, thickened with just enough cornstarch to help it cling to the leaves, adds a depth of umami without overpowering the vegetables. The result is clean, simple, and deeply satisfying.

There are countless ways to make this dish, depending on the household. Some families may want their sauce thicker or sweeter, and others might incorporate fresh chiles. I prefer to keep the aromatics simple, using just garlic. The sauce is equally unfussy: Oyster sauce forms the base, light soy sauce adds salt and umami, and a pinch of sugar rounds it out—no chicken stock, bouillon, or special broth needed. This dish is about letting the lettuce and sauce shine.

Blanching takes just seconds. Use a large pot of boiling water to minimize the temperature drop when adding the greens, and since we're serving the lettuce warm, there's no need for an ice bath (one less bowl to wash!). Once the lettuce wilts, drain it immediately by lifting it with tongs and arrange it on a serving platter.

Choosing and Preparing the Lettuce

As for lettuce varieties, romaine works best. It's sturdy enough to withstand blanching without becoming mushy, and it's easy to find, too. Skip the bagged salad mixes—the chopped or broken up leaves are often too delicate and won't hold up in hot water.

To prep the lettuce, separate the leaves and rinse thoroughly to remove any grit. Don't worry about drying them completely, as they're going into the blanching water anyway. Just shake off excess water, trim any bruised or browned spots, and set them aside. Since the cooking process is lightning-fast, I recommend having everything ready before preparing the sauce to make it as quick and easy as possible.

Unlike many stir-fried vegetable dishes (such as choy sum with garlic) in which the sauce is quickly built in the wok after the vegetables cook, this recipe flips the order. Because lettuce cooks in seconds, the sauce is prepared first, then poured over the blanched greens. This way, the vegetables don't overcook while you tend to the aromatics.

A wok won't be necessary—just a small saucepan will do. Gently sweat the garlic over medium heat until fragrant—don't let it take on color—then add the oyster sauce, light soy sauce, and sugar, and bring to a simmer. Stir in a cornstarch slurry, then let the sauce thicken slightly. It should be pourable but still glossy and thick enough to cling to each leaf.

Some recipes call for tossing the blanched lettuce with the sauce in a wok. I don't think it's necessary, as it overcomplicates things and can mute the fresh flavor of the greens. Pour the sauce over the lettuce, and serve with rice.

Best Served Fresh

Leftovers? They're technically fine to serve. The dish can be reheated gently or even eaten cold, but the texture suffers. This is one of those recipes best made fresh in just the amount you plan to eat. Or you could do what I do: Go back for seconds and finish it all.
