Rau Muống Xào Tỏi (Garlic Water Spinach)
This is one of those dishes that brings me straight back to the dinner table growing up. There was almost always a plate of garlic-sautéed greens next to a bowl of rice and whatever main dish we were eating that night. If you’ve had rau muong at a Vietnamese restaurant, you already know how simple and good it is. Tender stems, crisp leaves, and just the right amount of garlicky, savory flavor.

Rau muong, also known as morning glory or water spinach, cooks fast and soaks up flavor beautifully. It’s affordable, easy to find at Asian markets, and an effortless way to add more greens to the table. While it’s a classic Vietnamese side dish, it works just as well with all kinds of Asian-inspired meals. It also happens to be a favorite of mine whenever I want to add something fresh and green without overthinking it. Ready in under 15 minutes. This one’s a keeper.
What Is Rau Muong?
Rau muong is the Vietnamese name for water spinach, a leafy green vegetable with hollow stems and tender leaves. It’s widely used across Southeast Asia and is prized for its crisp texture and mild flavor.
In English, you might see it labeled as water spinach or morning glory at Asian grocery stores. Once cooked, it stays vibrant and slightly crunchy, making it perfect for quick stir-fries like this one.
Ingredients You’ll Need
Water spinach is the star, so freshness matters. Look for bunches with firm stems and bright green leaves, and trim off any tough ends before cooking.

Garlic provides most of the flavor here, so don’t be shy. Minced or thinly sliced both work.
Oyster sauce adds savory depth and a bit of gloss, while a small amount of sugar balances everything out. A neutral oil keeps the focus on the vegetables, and fried garlic is optional but nice if you want extra aroma on top.

How to Make Rau Muong Xao Toi
Start by prepping the water spinach. Trim away any tough or woody ends and cut the stems into manageable pieces so they cook evenly.


Blanching is a quick but important step. A short dip in boiling water softens the stems and keeps the color bright. Drain well so you don’t add extra moisture to the pan.


Once the pan is hot, sauté the garlic just until fragrant. Add the blanched water spinach and toss quickly so it’s coated in the oil and garlic.
Finish with oyster sauce and sugar, stirring just long enough for everything to come together. This dish cooks fast, so once it’s glossy and heated through, it’s ready to serve.


Tips for the Best Stir-Fried Water Spinach
✔️ Blanch briefly and don’t overcook. You want the stems tender but still slightly crisp.
✔️ Drain the greens well after blanching to avoid watering down the sauce.
✔️ Have everything ready before you start cooking. From the garlic to the sauce, this dish comes together in just a few minutes.
✔️ If you like a bit of heat, a small pinch of chili flakes or a drizzle of chili oil works well.
What to Serve with Rau Muong
Rau muong is often served as part of a shared Vietnamese meal. It pairs especially well with rice-based dishes like Vietnamese fried rice (com chien) or richer mains such as thit kho.
For noodle meals, it’s a great vegetable side alongside soups like bun rieu, pho tai, or bun bo hue, adding something fresh and green to the table. It also works nicely with grilled dishes like bun thit nuong when you want a simple vegetable to round things out.

How to Store and Reheat
Rau muong is best eaten right after cooking, when the texture is still bright and crisp.
If you do have leftovers, store them in an airtight container in the fridge for up to 2 days. Reheat gently in a pan over medium heat just until warmed through. Avoid microwaving if possible, as it can make the vegetables limp.

A Simple Vegetable Worth Keeping on Repeat
This stir-fried water spinach is proof that you don’t need a long ingredient list to make something good. It’s quick, flexible, and fits into almost any Vietnamese meal, whether you’re cooking rice, noodles, or a full spread.

RECIPE
Rau Muống (Stir Fried Morning Glory with Garlic)
Ingredients
- 1 pound water spinach (rau muong), washed and trimmed
- 1 tablespoon vegetable oil
- 3 garlic cloves, minced or thinly sliced
- 2 tablespoons oyster sauce
- ½ teaspoon sugar

Instructions
- Prep the water spinach. Trim tough ends and discard any wilted leaves. Cut into 3–4 inch sections.
- Blanch briefly. Bring a large pot of water to a boil. Blanch the water spinach for 1–2 minutes until just tender but still vibrant. Drain well and set aside.
- Sauté the garlic. Heat oil in a large wok or skillet over medium-high heat. Add garlic and cook for about 30 seconds, just until fragrant.

- Season. Add oyster sauce and sugar. Toss for another 1–2 minutes until glossy. Season with salt and pepper to taste.
- Serve. Transfer to a plate and top with fried garlic if using. Serve immediately.
Notes
- Blanching first keeps the stems tender and the color bright while preventing excess moisture in the pan.
- Drain the water spinach well before stir-frying so the sauce doesn’t get watered down.
- This dish cooks fast. Have everything ready before you start.
- For extra heat, add a pinch of chili flakes or a drizzle of chili oil at the end.
Good recipe but was so sweet. Will need to try without the sugar next time.
It’s a favorite side dish of mine. I always add sliced up Thai chili peppers for some added heat during stir-frying.
