With just a little chopping and about ten minutes in a hot pan, this spicy silken tofu recipe delivers tender, custardy tofu in a savory, slightly fiery sauce. Serve it steaming over rice so every drop of sauce is soaked up. It’s perfect for vegans, vegetarians, and anyone who loves bold, satisfying food.
This is my copycat version of a favorite from a local Chinese restaurant — known there simply as Do Fu con salsa china (Tofu with Chinese sauce). I kept the textures, boosted the umami, and made it quick to prepare at home.

🛒 Ingredients
Vegetables: I use carrots, shiitake mushrooms, green bell pepper, and onion to mirror the original dish. Feel free to swap or add vegetables, but keep the tofu as the main ingredient.
Mushrooms: Shiitake bring a lot of savory depth. Use fresh shiitake when you can; dried rehydrated ones also work. If you must substitute, use a meaty mushroom like portobello, but the flavor will be less intense.
Sesame oil: A small amount of toasted sesame oil adds aroma and silkiness. Omit if you don’t like it, but a little goes a long way.
Chili garlic sauce: This ingredient is crucial for the character of the sauce. It provides both heat and fermented, garlicky umami. If you’ve never tried it, start with the amount in the recipe and taste as you go.
Rice vinegar: Use rice vinegar for a mild, rounded acidity. If you don’t have it, a mild white wine vinegar is an acceptable substitute.
Soy sauce: Light soy sauce or tamari works best for seasoning without adding too much color. Avoid dark soy sauce here; it’s stronger and can overwhelm the balance.
Silken tofu: The star of the dish. Use firm or extra-firm silken tofu (not the very soft dessert style). This recipe uses a larger 17 oz (about 480 g) block commonly found in Asian grocery stores.
Cornstarch/cornflour: Makes the sauce glossy and restaurant-style. Tapioca, arrowroot or potato starch can be used if needed; you may need to adjust amounts.

👩🍳 How to make it
This is a straightforward silken tofu recipe: dice the vegetables, whisk the sauce, stir-fry the veg, then add tofu and simmer briefly so the tofu warms through and the sauce thickens.
Organize your mise en place before you heat the pan: chop the vegetables, drain and cut the tofu, and whisk the sauce (except the cornstarch) in a bowl.
Step 1: Small-dice the carrots, onion and pepper. Wipe shiitake mushrooms clean, halve and slice thinly.
Step 2: Whisk the sauce ingredients (vegetable broth, light soy sauce, rice vinegar, chili garlic sauce, toasted sesame oil, sugar, and garlic) together in a bowl, leaving out the cornstarch for now.
Step 3: Heat 1½ tablespoons sunflower or canola oil in a wok or large pan on high until very hot. Drain the tofu (do not press), cut into ½–1 inch pieces, then add the vegetables and stir-fry about three minutes until softened.
Step 4: Pour in the whisked sauce, add the tofu, and gently combine. Bring to a boil over high heat and simmer for three minutes. Meanwhile, whisk 1 tablespoon cornstarch with ¼ cup cold water until smooth.
Add the cornstarch slurry to the pan, stir carefully, and when the sauce returns to a boil, simmer for another two minutes until thick and glossy. Remove from heat and taste for seasoning — add salt if needed (about ¾–1 tsp is typical, depending on stock and chili sauce). Serve immediately over steamed rice.
💡 Expert tips
- Prepare everything before you start cooking. This dish moves quickly once the pan is hot.
- Use a food processor to speed up chopping if you have one — pulse the carrot, onion and pepper to a fine dice.
- Always mix cornstarch with cold water to avoid clumping.
- This is generally mild-to-medium spicy. Add extra chili garlic sauce to increase heat after cooking if desired.
- In the UK and Ireland, cornflour is the same as cornstarch in the US — a fine white thickener. Do not confuse it with yellow corn flour.
🍽️ Serving suggestions
Try serving this spicy silken tofu:
- Over steamed basmati or long-grain rice to soak up the sauce.
- Over boiled or pan-fried noodles for a heartier meal.
- On its own as a warming, saucy tofu stew.
- With a crisp cucumber salad or Asian-style slaw for contrast.
- Garnished with chopped cilantro and a sprinkle of red pepper flakes, if you like extra heat.
❓ FAQ
It’s typically medium in heat. Start with the recipe amount of chili garlic sauce and add more at the end if you want it hotter. Different brands vary in spice, so adjust to taste.
Store leftovers in an airtight container in the refrigerator for up to five days. The sauce may intensify in flavor over time. Freezing silken tofu changes its texture, so I don’t recommend freezing this dish.
Reheat gently in a pan over low-medium heat or warm covered in the microwave until heated through.
Silken tofu can be eaten uncooked, but this recipe benefits from warming so the flavors infuse the tofu and the sauce becomes silky.
Silken tofu is nutrient-dense, providing plant-based protein with relatively few calories and little saturated fat. It can be part of a balanced diet.

Buy the larger 17 oz packs of silken tofu at Asian markets — they offer better value. Use a high-quality chili garlic sauce for the best flavor. If you must substitute the chili garlic sauce, reduce the amount and taste as you go.
