Salt and Pepper Tofu (椒盐豆腐) is a beloved Cantonese vegetarian classic — crispy golden cubes of tofu tossed with a fragrant salt-pepper mix, chili, and scallions. The exterior shatters, the interior stays silky, and the spicy-savory seasoning makes it dangerously snackable. Here is the restaurant method.
Salt and pepper tofu (椒盐豆腐) is a Cantonese dish of deep-fried tofu cubes tossed with a spicy salt-and-pepper seasoning, dried chilies, and scallions. It is crispy outside, silky inside, and a popular vegetarian restaurant dish.
椒盐 (jiāo yán, “pepper salt”) is one of the great Cantonese seasoning formulas, and tofu is where it shows off best. The dish belongs to the same family as 椒盐虾 (salt and pepper prawns) and 椒盐鲜鱿 (salt and pepper squid) — all built on a light starch coating, a hot fry, and a final toss with garlic, chili, and the salt-pepper mix. Where the seafood versions rely on the natural sweetness of shellfish, the tofu version is a texture play: a brittle, bubbled crust giving way to a custard center, with the seasoning catching in every crevice.
This recipe comes from a vegetarian restaurant in Hong Kong where the chef taught me the essential trick: double-fry the tofu. The first fry sets the crust; the second fry at higher heat makes it shatteringly crisp while the inside stays custard-soft.
Why the Double Fry Is Non-Negotiable
A single fry gives you tofu that is crisp for about ninety seconds — long enough to reach the table, not long enough to enjoy. The double fry solves this. The first pass at 160°C (320°F) cooks the coating through and drives out surface moisture; the tofu then rests while you finish the batch. The second pass at 190°C (375°F) flashes off the remaining moisture and sets a hard, glassy shell. That shell is what keeps the interior steaming hot and custardy while the outside stays audibly crunchy — and it is why restaurant salt and pepper tofu arrives at the table still crackling.
Choosing and Pressing the Tofu
- Firm or extra-firm tofu holds its cube shape and crisps best; silken tofu disintegrates
- Press for 20–30 minutes under a weighted plate or tofu press to drive out water — wet tofu steams instead of crisping
- Cut into 2.5cm (1 in) cubes — big enough for a custardy center, small enough to cook through
- Pat bone dry after pressing, then dust with potato starch right before frying
- Potato starch over cornstarch — it fries lighter and blisters more dramatically
Ingredients and Where to Find Them
- Firm tofu — firm or extra-firm tofu, pressed and cubed
- Potato starch — potato starch for the light, blistered coating
- White pepper — ground white pepper is the 椒 in 椒盐; grind it fresh if you can
Also needed: garlic, fresh red chilies, scallions, five-spice powder, salt, and oil for frying. A pinch of sugar in the seasoning mix rounds out the salt and makes the whole thing moreish.
How to Cook It
- Press 450g (1 lb) firm tofu for 25 minutes, then cut into 2.5cm cubes and pat dry
- Toss the cubes with 3 tablespoons potato starch until evenly dusted, shaking off the excess
- Heat oil to 160°C (320°F) and fry the tofu in batches for 3 minutes until pale gold; drain on a rack
- Raise the oil to 190°C (375°F) and fry again for 60–90 seconds until deep golden and crisp; drain
- Mix the seasoning: 1 teaspoon sea salt, 1 teaspoon white pepper, and 1/2 teaspoon five-spice powder
- Pour off all but 1 tablespoon oil, then stir-fry 5 minced garlic cloves, 2 sliced red chilies, and the scallion whites for 20 seconds
- Toss the tofu with the seasoning mix and scallion greens for 30 seconds and serve immediately
Variations
- Air-fryer version — toss in 1 tablespoon oil plus the starch and air-fry at 200°C (400°F) for 15 minutes, shaking twice; less crisp but far less oil
- Salt and pepper mushrooms — king oyster or oyster mushrooms work beautifully with the same coating
- With Sichuan peppercorn — add 1/2 teaspoon ground Sichuan peppercorn to the seasoning for a numbing edge
- Spicier version — double the chilies and add 1 teaspoon chili flakes to the toss
Frequently Asked Questions
What tofu should I use?
Firm or extra-firm tofu holds its shape and crisps best. Silken tofu will fall apart; use it only if you want a soft, coated version. Medium-firm is a workable middle ground if you press it thoroughly.
Why did my tofu turn soggy?
Almost always moisture. Tofu is sold packed in water, and that water has to come out before frying — press it for at least 20 minutes, pat it dry, and dust with starch immediately before it hits the oil. Skipping the second fry also shortens the crisp window dramatically.
Can I make this without deep-frying?
Yes. Pan-fry in 1cm of oil, turning to brown all sides, or air-fry at 200°C (400°F) for 15 minutes with a light oil coating. Neither gets quite as shatteringly crisp as a double fry, but both are excellent and use far less oil.
Is this dish vegan?
Yes, as written — tofu, starch, aromatics, and seasonings contain no animal products. Check your five-spice blend if you are strict, as a few commercial mixes include unexpected additives.
