Tofu does not usually get to be the star of the table, but air fryer foil tofu changes that in about half an hour. You slide a whole block of silken tofu into a foil container, score it, flood it with beaten egg, and let the air fryer turn that into a soft golden blanket. Then comes the part that makes the kitchen smell incredible: hot oil poured over garlic and chili until it crackles, loosened with soy sauce and oyster sauce, spooned back over the tofu for one last blast of heat.
What you end up with is custardy in the middle, gently set on the surface, and glossy with a sauce that tastes like the best part of a street-stall grill. Scoop it with a spoon, pile it on rice, and try not to eat the whole tray standing at the counter — I have failed this test more than once. It is also the rare tofu dish that needs no pressing, no draining overnight, and no special skill with a wok. If you can open a foil pan and chop garlic, you can make this tonight.
What Is Air Fryer Foil Tofu?
Xizhi doufu (锡纸豆腐) literally means “foil tofu,” and it is exactly what the name promises: tofu cooked inside a foil packet or foil tray. In China you will find it at street stalls and takeout shops, where a block of soft tofu goes into foil with egg or a sauce, gets steamed or grilled, and comes out silky with a deeply savory topping. The foil is not decoration — it holds a delicate ingredient together, keeps the egg from running off, and lets the tofu steam gently in its own moisture while the top sets.
The air fryer version borrows that same logic. A foil container fits neatly into the basket, the circulating hot air sets the egg and lightly browns the edges, and the tofu stays soft underneath because it is never handled. It is faster and cleaner than the stovetop original, and it produces the same contrast that makes the dish worth ordering: soft, jiggly tofu against a punchy, oily, garlicky sauce.
Think of foil tofu as a Chinese answer to a baked egg custard: the egg is not a coating, it is a soft set layer that carries the sauce. That is why the tofu is scored first — the shallow cuts let the egg and sauce sink into the block instead of sitting on top.
If you already cook with silken tofu, this dish fits right into your rotation. It is lighter and saucier than pan fried tofu with garlic sauce, which uses firmer tofu and a drier, more caramelized finish. Where that recipe gives you crisp edges, this one gives you spoonable custard.

Why This Recipe Works
Three things make this dish reliable. First, the foil container. Silken tofu is fragile enough that moving it mid-cook would tear it, so the foil becomes both cooking vessel and serving dish. You never lift the tofu, and it never breaks.
Second, the two-stage air fry. The first 10 minutes set the egg into a soft skin that holds the sauce. The second 5 minutes, after the sauce goes on, warms the garlic and lets the glaze cling instead of pooling. Skipping either stage gives you either raw egg or a sauce that slides straight off.
Third, the hot-oil pour. Pouring shimmering oil over raw garlic and chili blooms the aromatics and takes the raw edge off the garlic in seconds. It is the same technique behind chili oil and garlic sauces across Chinese cooking, and it is the difference between a sauce that tastes sharp and one that tastes rounded and fragrant.
One more quiet advantage: this recipe uses a whole block of tofu with no pressing. Silken tofu is sold packed in water and already hydrated, so there is nothing to squeeze out. You drain it, slide it into the foil, and go.
Equipment Needed
An air fryer is the only appliance you truly need, and any model with a basket large enough for a small foil tray will work. A 5- to 6-quart air fryer fits a standard foil container comfortably; if yours is smaller, use two smaller trays and cook them in batches, or halve the recipe.
You will also want a small heatproof bowl for the aromatics — metal or thick ceramic, since hot oil goes in — plus a small pan for heating that oil, a cutting board, a knife, and a spoon for scooping at the end. A pair of tongs helps when you lift the hot foil tray out of the basket. If you do not own a foil container, a double layer of heavy-duty foil folded into a tray with raised sides works just as well; just make sure the sides are high enough to hold the egg.
No air fryer? You can steam the tofu in the foil over simmering water for 10 minutes, then pour the sauce over and steam 3 minutes more. The texture will be softer and there will be no browned edges, but the flavor is still excellent.
Ingredients
The list is short, which means each item matters. Here is what goes into the tray and why.
- Silken tofu (内酯豆腐), 1 block, about 16 oz. The soft, jiggly kind sold in a plastic tub in the refrigerated section. Do not substitute firm or extra-firm tofu here; the whole point is the custard texture.
- Eggs, 2 large. Beaten and poured over the tofu, they set into the soft layer that holds the sauce.
- Garlic, 3-4 cloves. Minced, not sliced. It goes into the bowl raw and gets cooked by the hot oil.
- Fresh red chili, 1. Sliced into thin rings. Use more or less depending on how much heat you want.
- Barbecue seasoning, 1 tbsp. The shortcut that gives this dish its street-stall flavor — a blend of chili, cumin, sesame, and salt. Chili powder plus a pinch of cumin is a fine substitute.
- Light soy sauce, 2 tbsp. Salty and savory without being heavy. Tamari works for gluten-free diets.
- Oyster sauce, 1 tbsp. Adds body and a subtle sweetness. Vegetarian oyster sauce or a splash of hoisin are both good swaps.
- Neutral oil, 3 tbsp. Heated until it shimmers, then poured over the aromatics.
- Cilantro, a small handful. Chopped and scattered at the end for freshness.
Ingredient Notes
Which tofu to buy. Look for the words “silken” or “内酯” on the tub. Silken tofu is sometimes labeled “soft” in Western supermarkets, but true soft tofu is slightly firmer and will not give you the same spoonable result. If you can only find soft, the dish still works — just expect a slightly more set texture.
Barbecue seasoning. Chinese barbecue seasoning (烧烤料) is a ready-made blend sold in small packets. If you cannot find it, mix 1 teaspoon chili powder, 1/2 teaspoon ground cumin, 1/4 teaspoon toasted sesame seeds, and a pinch of salt. A little sugar — about 1/4 teaspoon — rounds out the sauce if your soy sauce is very salty.
Oyster sauce. This is what gives the glaze its glossy body. If you are cooking vegetarian, use a mushroom-based vegetarian oyster sauce. If you are avoiding shellfish entirely, a teaspoon of dark soy sauce plus a pinch of sugar gets you close.
Soy sauce. Light soy sauce is the default for Chinese cooking. Dark soy sauce would make the glaze too heavy and too dark here, so keep it light. Tamari is the best gluten-free swap.
Chili. A single small red chili (小米辣) is genuinely spicy. If you want the flavor without the burn, use half a chili and remove the seeds, or substitute a teaspoon of mild chili flakes.
Prep & Mise en Place
Everything in this recipe moves quickly once the air fryer starts, so set yourself up before you turn it on. Total hands-on prep is about 15 minutes, and most of that is chopping.
Start by draining the tofu. Open the tub, pour off the packing water, and let the block sit on a plate for 10 minutes while you work on everything else. You do not need to press it — just let the excess water run off so the egg clings instead of sliding.
Next, get the aromatics ready. Mince the garlic finely, slice the chili into thin rings, and chop the cilantro. Put the garlic, chili, and barbecue seasoning together in a small heatproof bowl so it is ready for the hot oil. Beat the eggs in a separate bowl until the yolks and whites are fully combined and slightly frothy.
Have your foil container set on a plate near the air fryer, and preheat the air fryer to 180°C (355°F) for 3 minutes if your model recommends preheating. Once the tofu has drained, slide it into the foil, score the top 3-4 times with a knife — shallow cuts, about halfway down — and you are ready to cook.
Cooking Process
Step 1 — Slide and Score the Tofu
Turn the silken tofu out into a foil container and score the surface 3-4 times with a knife.
Step 2 — Prep the Aromatics
Beat the eggs, slice the red chili into rings, chop the cilantro, and mince the garlic.
Step 3 — First Air Fry
Pour the beaten egg over the tofu and air fry at 180°C (355°F) for 10 minutes.
Step 4 — Build the Sauce Base
Make the sauce base: in a small bowl combine the minced garlic, chili rings, and 1 tablespoon of barbecue seasoning.
Step 5 — Sizzle and Stir the Sauce
Heat a little oil in a pan until it just begins to smoke, pour it over the aromatics so it sizzles, then stir in 2 tablespoons of soy sauce and 1 tablespoon of oyster sauce and mix well.
Step 6 — Second Air Fry
Spoon the sauce over the air-fried tofu and air fry again at 180°C (355°F) for 5 minutes.
Step 7 — Finish and Serve
Scatter the cilantro on top and scoop it out with a spoon to eat.
Common Mistakes When Making Air Fryer Foil Tofu
1. Using firm tofu instead of silken. Firm tofu will not turn custardy; it stays rubbery and the egg sits on top like a separate layer. The fix is simple: buy the tub labeled silken or 内酯, and save the firm block for a stir-fry.
2. Skipping the drain. If the tofu is still sitting in water, the beaten egg dilutes and slides off the sides instead of setting on top. Let it drain for at least 10 minutes, and blot the surface gently with a paper towel if it still looks wet.
3. Burning the garlic with the hot oil. Garlic goes from fragrant to bitter in seconds. Pour the oil in two stages — a small splash first to start the sizzle, wait a moment, then the rest — and pull the pan off the heat the instant the oil begins to smoke. If the garlic turns dark brown, start over; there is no fixing bitter garlic.
4. Overfilling the foil tray. A tray that is too small means the egg and sauce overflow into the air fryer basket, which is a mess to clean and leaves the tofu dry. Use a container with at least an inch of headroom above the tofu, or split the recipe between two trays.
5. Skipping the second air fry. It is tempting to pour the sauce on and eat, but those 5 extra minutes are what warm the garlic and thicken the glaze so it coats the tofu. Without them the sauce tastes raw and sits in a puddle.
6. Adding the sauce too early. If you pour the sauce on before the egg sets, the two merge into a loose scramble. Always let the first 10-minute cook finish and the egg firm up before the sauce goes on.
Variations
Minced pork version. Brown 1/4 lb of ground pork with a splash of soy sauce and scatter it over the tofu before the second air fry. It turns the dish into a heartier main course and echoes the meat-topped foil tofu sold at night markets.
Century egg version. Dice a century egg and tuck the pieces into the scored tofu before the egg goes on. The creamy, slightly funky yolk pairs beautifully with the garlic sauce — the same flavor pairing as silken tofu with century egg.
Seafood version. Add a handful of small peeled shrimp to the tray for the last 5 minutes. They cook through in the residual heat and turn the dish into something closer to silken tofu and shrimp soup in flavor, though the texture stays firm and saucy.
Vegan version. Skip the egg entirely. Score the tofu, air fry it plain for 8 minutes to dry the surface, then add the sauce (made with vegetarian oyster sauce) and air fry 5 minutes more. The result is less custardy but still excellent.
Extra-spicy version. Double the chili, add a teaspoon of chili oil to the sauce, and finish with a pinch of Sichuan peppercorn powder for a numbing edge.
Frequently Asked Questions
Can I make this without an air fryer? Yes. Steam the foil tray over simmering water for 10 minutes, add the sauce, and steam 3-5 minutes more. You will lose the browned edges but keep the silky texture.
Why did my egg slide off the tofu? The tofu was still wet, or the egg was poured on before the surface was drained. Drain for 10 minutes and blot gently; the egg needs a slightly dry surface to grip.
Can I use firm or medium tofu? You can, but the dish changes character. Firm tofu holds its shape and gives you a chewier, more sliceable result. If that is what you have, add 3-4 minutes to the first air fry and expect less custard.
How spicy is this? One small red chili in the sauce gives a medium, lingering heat. The barbecue seasoning adds a little more. For a mild version, use half a chili with the seeds removed and a mild chili powder.
Can I prep it ahead? You can chop the aromatics and mix the dry seasoning up to a day ahead and refrigerate them. Cook the tofu fresh, though — it is at its best within 20 minutes of coming out of the air fryer.
How to Serve
Air fryer foil tofu is a spoonable dish, so serve it in the foil tray set on a plate, with steamed white rice alongside to catch the sauce. A vegetable stir-fry or a simple cucumber salad rounds out the meal. Because the sauce is rich, something light and cold on the side balances it well.
For a Chinese-style spread, pair it with quick kimchi for a tangy, crunchy contrast, or with Chinese borscht if you want a soup course that is sweet, tomatoey, and comforting next to the garlicky tofu.
Storage & Reheat
Leftover foil tofu keeps in the refrigerator for up to 3 days. Transfer it to an airtight container once it has cooled, and keep the sauce with it — the tofu will absorb some of the glaze and taste even better the next day.
To reheat, the air fryer is again your best tool: 160°C (320°F) for 4-5 minutes, covered loosely with foil so the egg does not dry out. A microwave works in a pinch — 60-90 seconds on medium — but the texture will be softer and the egg may weep a little liquid. Do not reheat more than once.
This dish does not freeze well. Silken tofu breaks down when frozen and thawed, turning spongy and releasing water, so make only what you plan to eat within a few days.
Allergen Notice
This recipe contains soy (tofu, soy sauce), egg, wheat (standard soy sauce), and shellfish (oyster sauce). For a soy-free version, use a soy-free tofu substitute and coconut aminos. For gluten-free, use tamari instead of soy sauce and confirm your oyster sauce is wheat-free. For shellfish-free, use vegetarian oyster sauce or a mix of dark soy sauce and sugar. Always check the labels on your barbecue seasoning, since blends can contain sesame, wheat, or added salt.

About the Author & Recipe Development
Lin grew up cooking Chinese food at home and has spent years adapting the dishes she loves for a Western kitchen — same flavors, easier equipment. This recipe comes from the foil tofu sold at Chinese street stalls and takeout counters, where a block of silken tofu is cooked in its own foil packet and finished with a hot garlic-chili sauce. The air fryer version was tested repeatedly to find the two-stage timing that sets the egg without drying the tofu, and to get the sauce thick enough to cling rather than pool. Every recipe on Wok of Love is tested in a home kitchen with ingredients you can find at a regular supermarket.
