All About Five-Spice Tofu
What is Five-Spice Dry Tofu?
This variety of tofu—also called wǔxiāng dòugān (五香豆干)—is pressed for a firm, chewy texture and infused with a marinade of Chinese five-spice powder, soy sauce, and sometimes additional aromatics. It’s readily available at Asian grocers in vacuum-packed blocks. Unlike soft or silken tofu, it holds shape under intense heat and absorbs sauces beautifully. If you cannot find this exact tofu, substitute with firm or extra-firm plain tofu, pressing it to remove moisture and marinating it in soy sauce and a small amount of five-spice powder for at least 30 minutes.
| Type of Tofu | Texture | Flavor Profile |
|---|---|---|
| Silken | Soft, custardy | Mild |
| Firm/Extra-Firm | Dense, holds shape | Mild/Absorbs marinades |
| Five-Spice Dry | Very firm, meaty | Savory, aromatic, umami-rich |
Origins of the Dish
Stir-fried combinations of green beans and tofu are common throughout Taiwanese and southern Chinese homes, reflecting a culinary tradition focused on fresh produce and efficient, flavorful preparation. Taiwan’s climate yields abundant green beans for much of the year, and tofu—particularly seasoned dry tofu—is widely enjoyed as a protein-rich staple. This dish is typically served as a side alongside rice and other homey stir-fries, but its robust flavors can stand at the center of a light vegetarian meal.
Essential Ingredients
- Fresh Green Beans: Firm, unblemished beans are ideal. Thinner “French style” or haricots verts work well, but standard green beans offer more crunch.
- Five-Spice Dry Tofu: Seek pre-flavored tofu packed in vacuum-sealed pouches at Asian supermarkets; slice thinly for maximum surface area.
- Garlic: Slivered or thinly sliced for an aromatic base.
- Red Chilies or Chili Flakes: Adds a gentle heat; adjustable to taste or omitted for milder palates.
- Soy Sauce: Light soy sauce is preferred for clean flavor and color. Dark soy can deepen richness but may overpower the dish.
- Sugar: Just a pinch smoothes and balances the savory base.
- Scallions: Sliced on the bias for both flavor and garnish.
- Neutral Oil: Such as peanut, canola, or grapeseed, which can withstand high stir-fry heats without smoking.
Technique: How to Achieve Crispy-Tender Beans
To preserve their signature crunch, green beans benefit from a brief blanching before being passed through the wok. Here’s why:
- Blanching in boiling water softens their exterior, reduces overall stir-fry time, and keeps their insides vibrant and crisp.
- Immediate shocking in ice water after boiling halts the cooking process and preserves bright green color.
- Drying the beans before stir-frying ensures they take on light blister and char in the wok, not steam.
Stir-Fry Basics
- Work in batches if increasing the quantity to prevent overcrowding, which can cause steaming instead of searing.
- Prep all ingredients before heating the wok; the cooking process moves quickly.
- Use the largest flame possible to maximize surface temperature and develop wok hei.

Step-by-Step: Taiwanese Stir-Fried Green Beans with Five-Spice Dry Tofu
Ingredients
- 8 ounces five-spice dry tofu (see note above)
- 8 ounces fresh green beans, trimmed
- 2 scallions, thinly sliced on a bias
- 2 to 3 cloves garlic, slivered
- 1 to 2 small fresh red chilies, sliced, or 1 teaspoon chili flakes (optional)
- 1 tablespoon light soy sauce
- 1/2 teaspoon sugar
- 1 to 2 tablespoons neutral oil (peanut, canola, or grapeseed)
- Salt, to taste
Instructions
- Prep the Beans: Bring a pot of salted water to a boil. Add trimmed green beans and cook for 1½–2 minutes, until bright green and just tender. Drain and transfer immediately to a bowl of ice water. Once cooled, dry thoroughly on towels.
- Prep Tofu and Aromatics: Slice five-spice dry tofu into thin batons or matchsticks. Prepare garlic, scallions, and chili.
- Heat the Wok: Place a large wok (or skillet) over the highest heat. Add the neutral oil and swirl to coat.
- Stir-Fry Tofu: Add sliced tofu to the hot oil. Stir-fry for 1–2 minutes until lightly browned at the edges. Remove tofu and set aside if necessary.
- Sauté Aromatics: Add garlic and chili to the remaining oil. Toss just until fragrant (about 30 seconds).
- Add Beans: Return dried green beans to the wok. Stir-fry for 2–3 minutes, pressing them against the hot metal to achieve some blistering.
- Combine and Season: Return tofu to the pan, add scallions, soy sauce, and sugar. Toss well and stir-fry until everything is coated and heated through (<1 minute).
- Finish and Serve: Taste for seasoning, adding salt if necessary. Transfer to a serving plate. Serve immediately as part of a home-style meal with steamed rice and other stir-fried dishes.
Tips, Variations, and Swaps
- No Five-Spice Tofu? Use extra-firm plain tofu, pressing out moisture and marinating it in a mixture of soy sauce and a pinch of five-spice powder for 30 minutes.
- Vegan & Gluten-Free Options: Ensure your tofu and soy sauce are free of wheat and animal byproducts; tamari can substitute for soy sauce if needed.
- Vegetable Ideas: Swap green beans for asparagus, snow peas, or even thin-sliced bell pepper for variety.
- Meatier Version: Add a small amount of stir-fried pork, crumbled tempeh, or dried mushrooms if a heartier dish is desired.
Serving Suggestions
This stir-fry is a versatile side or light entrée. Pair with:
- Steamed white or brown rice
- Other Taiwanese favorites: Think three-cup chicken, braised pork belly, or pickled mustard greens
- Soup: A bowl of hot-and-sour soup or light broth enhances the meal’s balance
Frequently Asked Questions (FAQs)
Can I use regular tofu instead of five-spice tofu?
Yes. Firm or extra-firm plain tofu can replace five-spice tofu. For best results, marinate it in a small amount of soy sauce and five-spice powder for flavor depth and let it absorb at least 30 minutes before cooking.
How do I store leftovers?
This dish is best eaten right after cooking for optimal texture, but leftovers keep in an airtight container in the refrigerator for up to 2 days. Reheat in a hot skillet rather than a microwave to help retain some crispness.
What is wok hei, and do I need a wok?
Wok hei (literally “breath of the wok”) refers to the complex, smoky flavors developed when ingredients are stir-fried at high heat. While a wok achieves the best results, a very hot, heavy skillet can work. Focus on high heat, quick movements, and not overcrowding the pan.
Is this dish gluten-free and vegan?
Yes, as long as you use gluten-free soy sauce (like tamari) and confirm the tofu is wheat-free. It is naturally vegan unless you add animal-based ingredients.
Nutrition and Health Benefits
This dish is high in plant-based protein from tofu, and green beans are a good source of vitamins (like vitamin K, vitamin C, and folate), fiber, and antioxidants. It’s low in saturated fat and cholesterol-free, making it suitable for a variety of dietary needs. Adjust salt and oil to taste if you are limiting sodium or fat.
Cultural Notes and Home Variations
In Taiwan, this stir-fry is a showcase of simple, bold home cooking. Households may tweak the aromatics, swapping garlic for shallots, or toss in handfuls of dried tiny shrimp for even more depth. The dish is popular at night markets, homestyle eateries, and lunchbox counters alike. It demonstrates that with the right ingredients and technique, even everyday vegetables can be transformed into something crave-worthy.
Takeaway
Taiwanese stir-fried green beans with five-spice tofu is so much more than a vegetable side—it’s a testament to the power of fresh produce, mindful preparation, and respect for tradition. Mastering this dish equips you with skills applicable to countless stir-fries and introduces you to one of Taiwan’s most satisfying home-kitchen staples. Gather fresh green beans, flavorful tofu, and a hot wok—then savor the results in every crisp, savory bite.
