How to Make Dry Pot in a Cast Iron Skillet (Tableside Sizzle Guide)
Key Takeaway
Preheat cast iron for 5 minutes until smoking — dry pot should arrive at the table still sizzling. Cast iron's massive heat retention keeps the dish bubbling through the entire meal, which is the whole point of gan guo.
Why This Changes Everything
Dry pot (gan guo, 干锅) is not a cooking method — it's a serving style. The dish is meant to arrive at the table in a sizzling-hot vessel that continues cooking as you eat. In Sichuan and Hunan restaurants, they use special dry pot burners, but at home, a cast iron skillet does the job perfectly. Cast iron's superpower is thermal mass. A 3kg cast iron skillet holds an enormous amount of heat — once it's hot, it stays hot for 20-30 minutes without a heat source. This is exactly what dry pot needs. The vegetables and meat keep sizzling at the table, the sauce reduces and intensifies, and the bits touching the pan develop a delicious charred crust. The cooking itself happens in two phases: stir-fry everything in a regular wok or pan (cast iron heats too unevenly for fast stir-fry), then transfer to the screaming-hot cast iron for the tableside presentation. Some recipes cook everything directly in cast iron, which works but requires more attention to hot spots.

Step-by-Step Guide
Start preheating the cast iron
prepPlace the cast iron skillet on a burner set to medium. Let it preheat for 5 minutes. This is not optional — cast iron needs time for the heat to distribute evenly across its thick walls. By the time you finish cooking in the wok, the skillet should be smoking hot.
Preheat cast iron for 5 minutes — it should be smoking when the food goes in. A properly heated cast iron skillet will maintain sizzling at the table for 15-20 minutes.
Prep all ingredients
prepSlice pork belly into thin strips (3mm). Slice lotus root and potato thinly (3mm) — thin slices cook fast and crisp at the edges. Break cauliflower into bite-sized florets. Cut onion into wedges. Halve dried chilies. Slice garlic and ginger. Organize by cooking order: protein first, then hard vegetables, then soft vegetables.
Stir-fry the protein
cookIn a separate wok or large pan, heat 1 tablespoon oil over high heat. Add pork belly slices and stir-fry for 2-3 minutes until the edges are golden and the fat has rendered. If using chicken, cook until just seared on the outside. Remove and set aside.
Do the stir-fry in a separate wok or pan — not the cast iron. Cast iron has uneven heat distribution that creates burnt spots during fast stir-fry. Use it only for the final presentation.
Stir-fry hard vegetables
cookIn the same wok, add lotus root and potato slices. Stir-fry for 2-3 minutes until the edges are golden and slightly translucent. These need the most cooking time, so they go first. Remove and set aside with the protein.
Keep the wok on high heat. Hard vegetables need aggressive stir-fry to develop the charred edges that make dry pot special.
Build the flavor base
cookReduce wok to medium heat. Add remaining oil. Add dried chilies and Sichuan peppercorns, stir for 20 seconds. Add doubanjiang and stir-fry for 30 seconds until the oil turns red and fragrant. Add garlic, ginger, and onion wedges. Stir-fry for 1 minute.
The doubanjiang is the soul of dry pot — it needs 30 seconds of frying in oil to bloom its flavor. Don't skip this step.
Combine everything
cookReturn all protein and vegetables to the wok. Add cauliflower florets (they cook in 1 minute). Add soy sauce and sugar. Toss everything together for 1-2 minutes over high heat. The dish should be saucy but not wet — dry pot has no soup.
Dry pot means dry — there should be no pooling liquid. If the mixture looks soupy, increase heat and stir-fry until the liquid evaporates.
Transfer to the smoking cast iron
cookYour cast iron skillet should now be smoking hot from its 5-minute preheat. Carefully pour the stir-fried mixture into the cast iron. You should hear an aggressive sizzle. Do not stir — let the bottom layer develop a crust for 30 seconds. Add green onion pieces on top.
Cast iron stays hot at the table — the dish keeps cooking, which is the point of dry pot. The bottom layer chars and gets crispy while you eat the top.
Serve at the table immediately
platePlace the cast iron skillet on a trivet or wooden board at the table — it will be extremely hot. Garnish with sesame seeds and cilantro. Eat directly from the skillet. The sizzling should continue for 10-15 minutes. The best bites are the charred pieces stuck to the bottom.
Warn everyone at the table that the skillet is 200°C+ and will stay dangerously hot for 20+ minutes. Use thick oven mitts or silicone handles when moving.
Common Mistakes
| Mistake | Why It Happens | How to Fix |
|---|---|---|
| Cast iron not hot enough — no sizzle at the table | Cast iron wasn't preheated long enough, or it was preheated on low heat. The massive thermal mass needs time to absorb heat throughout | Preheat on medium for a full 5 minutes. Test by flicking water — it should evaporate instantly with an explosive sizzle. If the food doesn't sizzle aggressively when transferred, the skillet wasn't ready. |
| Everything cooked directly in cast iron (burnt spots) | Cast iron has hot spots, especially over gas or electric burners. The center directly above the flame gets much hotter than the edges, leading to uneven cooking during stir-fry | Do the actual stir-fry in a wok or regular pan. Use the cast iron only for the final presentation. Transfer the fully cooked dish to the smoking-hot cast iron for the tableside sizzle effect. |
| Dry pot has too much liquid (soupy, not dry) | Vegetables released water during cooking, or too much sauce was added. Dry pot should be oily and coated, not swimming in broth | Stir-fry vegetables in batches to avoid steaming. Use doubanjiang + soy sauce for coating, not braising liquid. If it looks wet, keep stir-frying on high until the liquid evaporates. |
| Food sticks permanently to cast iron | Cast iron wasn't seasoned properly, or sugary sauce was added to a cold skillet | Maintain your cast iron seasoning (oil and bake regularly). Always transfer food to a fully preheated skillet. A thin film of oil before adding food helps. After serving, deglaze with hot water while the pan is still warm. |
Equipment Comparison
| Aspect | Cast Iron Skillet | Gas Stove | Other |
|---|---|---|---|
| Heat retention (tableside) | Exceptional — stays sizzling 15-20 min off heat | N/A (serving vessel, not heat source) | Stainless: cools in 5 min. Non-stick: cools in 3 min |
| Crust development | Excellent — heavy mass = consistent char | N/A | Stainless: good. Non-stick: none (coating prevents) |
| Even stir-fry cooking | Poor — hot spots, use only for finishing | Wok on gas: excellent | Wok on induction: good with flat-bottom |
| Weight | Heavy (2-4kg) — sturdy for tableside | N/A | Stainless: lighter. Non-stick: lightest |
| Presentation impact | Best — dramatic sizzle, restaurant feel | N/A | Stainless: decent. Non-stick: no sizzle (unsafe to overheat) |
FAQ
Can I cook dry pot entirely in the cast iron without a wok?
You can, but the results won't be as good. Cast iron has uneven heat distribution that creates hot spots — some ingredients burn while others are undercooked. Stir-fry in a wok for even cooking, then transfer to the preheated cast iron for presentation. If you must use only cast iron, cook in very small batches and stir constantly.
What size cast iron skillet works best for dry pot?
A 25-30cm (10-12 inch) skillet works best for 2-4 servings. Smaller than 25cm and the food piles too high (uneven cooking). Larger than 30cm and there isn't enough food to retain heat. A 28cm Lodge skillet is the sweet spot for most home cooks.
How do I clean cast iron after dry pot without ruining the seasoning?
While the skillet is still warm (not hot), add hot water to deglaze. The charred bits will loosen. Scrub with a stiff brush or chain-mail scrubber — no soap needed for a well-seasoned pan. Dry immediately on the stove over low heat for 1 minute. Rub with a thin layer of oil. This actually improves the seasoning over time.
What's the difference between dry pot and hot pot?
Hot pot (火锅) is a communal soup — you cook raw ingredients in boiling broth at the table. Dry pot (干锅) is pre-cooked and arrives already done, sizzling in a dry (no broth) vessel. Dry pot uses oil and spices for flavor instead of broth. Think of it as 'stir-fry served in a sizzling pan' versus 'cook-at-the-table soup.'
Can I use an enameled cast iron (like Le Creuset) for dry pot?
Not ideal. Enameled cast iron's smooth surface doesn't develop the same char as raw cast iron. The enamel can also crack under the extreme dry-heating required for dry pot. Use a traditional, uncoated cast iron skillet. Lodge, Victoria, and Chinese-made cast iron skillets are all excellent and affordable.
