If you love Thai food that’s fast, bold, and deeply satisfying, you’re going to love Kui Chai Pad Tub (กุยช่ายผัดตับ). This classic Thai stir-fry combines tender pork liver, fragrant garlic, and crisp Chinese chives (kui chai) in a savory sauce built from oyster sauce + soy sauce, finished with a touch of sugar and pepper for balance.

This is a dish many Thai people know as an everyday comfort meal—something you can order quickly at a local shop, or cook at home in minutes when you want a strong, savory stir-fry that pairs perfectly with hot jasmine rice.

What is Kui Chai Pad Tub?

Kui Chai (กุยช่าย)

Kui chai refers to Chinese chives / garlic chives. In Thailand, they’re used in stir-fries, dumplings, savory pancakes, noodle dishes, and even some soups. They taste like a gentler cousin of garlic and green onion—fresh, aromatic, slightly garlicky, and very “Thai.”

Pad Tub (ผัดตับ)

Pad means stir-fried.
Tub means liver.
So Pad Tub is simply “stir-fried liver.”

Together, Kui Chai Pad Tub is a wok stir-fry of liver and garlic chives with a savory sauce. You’ll see versions made with pork liver (very common), but sometimes also chicken liver or mixed organ meats depending on the shop and region.

Cultural notes: Why Thais love this dish

Thai home cooking often celebrates ingredients that many Western kitchens overlook—liver, tripe, intestines, blood tofu, fermented fish sauce, and more. These foods are part of a tradition of using the whole animal, wasting less, and turning nutrient-dense ingredients into tasty, everyday meals.

In Thai food culture, liver dishes show up in two main places:

1. Street food & quick meals — fast wok dishes like Pad Tub are common in small restaurants that serve rice plates.
2. Comfort and “strength” foods — many Thai families consider liver “good for blood” because it’s rich in iron and nutrients.

In other words: this dish isn’t “weird” in Thailand. It’s normal, familiar, and comforting—especially when cooked hot and served with rice.

Ingredients (simple, classic Thai pantry)

Main ingredients

• Pork liver — sliced into bite-size pieces
• Garlic — chopped (Thai cooking loves garlic as the first aroma)
• Chinese chives (kui chai / garlic chives) — cut into 3–5 cm pieces

Note: In your ingredient list you wrote “spring onions.” You can use spring onion, but garlic chives are the traditional choice for Kui Chai Pad Tub. Spring onion is a decent substitute or can be mixed in.

Seasoning

• Oyster sauce — provides deep umami and gentle sweetness
• Soy sauce — adds salt and savory depth
• Sugar — balances salt and gives Thai-style roundness
• Pepper — key for aroma and warmth

Optional but helpful

• A splash of water or stock (for sauce to coat evenly)
• Neutral oil (vegetable/canola/rice bran)
• Chili (if you want heat)

The #1 key: How to make liver tender (and reduce strong smell)

A lot of people say they “don’t like liver” because they’ve only eaten it overcooked or poorly prepped. Thai cooking treats liver like a quick stir-fry protein, not like something you simmer forever.

Quick prep method (easy, effective)

1. Rinse quickly, then pat dry
2. Slice even thickness (thin to medium—don’t make thick chunks)
3. Optional: soak 10–15 minutes in cool water, then drain well
4. Keep it chilled until cooking (texture stays better)

Optional (extra) smell-reducing tricks

• A quick soak in milk (10–15 minutes) can soften strong notes
• A quick rinse with a little lime juice can freshen the aroma (don’t soak long)
• Cooking with garlic + pepper (Thai style) naturally helps too

Cooking rule

High heat + short time = tender.
If you cook liver too long, it turns firm and grainy.

Step-by-step: Thai wok method (fast, clean, flavorful)

This dish is perfect for a wok, but a large hot pan works too.

1) Prep everything first (mise en place)

Thai stir-fries move fast. Have these ready:

• chopped garlic
• sliced liver
• cut garlic chives
• sauces measured (or at least nearby)

2) Heat the wok

Use high heat. You want that quick Thai “wok cooking” style.

3) Stir-fry garlic first

Add oil, then garlic. Stir quickly until fragrant.

Tip: If garlic starts browning too fast, lower heat slightly or add liver sooner. Burnt garlic will make the whole dish bitter.

4) Add liver and cook quickly

Add the liver and toss quickly. The pieces will change color fast.

Goal: Cook until just done (still juicy).

5) Season

Add:

• oyster sauce
• soy sauce
• sugar
• pepper

If the pan looks dry, add a splash of water to help the sauce coat the liver.

6) Add garlic chives last

Add the chives and toss for a short time—just until bright green and slightly softened.

Don’t overcook the chives or they lose their crispness and vibrant look.

7) Serve immediately

This dish is best hot, fresh, and eaten right away.

Taste profile (what to expect)

• Savory + umami from oyster sauce and soy sauce
• Slight sweetness to balance salt (classic Thai technique)
• Peppery warmth that lifts the aroma
• Green freshness from garlic chives
• Rich, tender texture from liver (when cooked correctly)

Common mistakes (and how to avoid them)

Mistake 1: Overcooking the liver

Fix: cook fast. Liver is not like pork belly or stew meat.

Mistake 2: Adding chives too early

Fix: chives go in last so they stay green and crisp.

Mistake 3: Too much sauce too early

Fix: keep it light. Thai stir-fries coat ingredients; they don’t swim in sauce.

Mistake 4: Pan not hot enough

Fix: preheat properly and don’t overcrowd. If you have a lot of liver, cook in batches.

Variations you can try

1) Spicy version (very Thai)

Add sliced Thai chilies with the garlic.

2) Ginger version (great for aroma)

Add thin ginger strips—excellent with liver.

3) Add vegetables

Onion, mushrooms, or morning glory are good. Just don’t overload the pan.

4) Chicken liver alternative

Use chicken liver instead, but cook even quicker (it overcooks fast).

What to serve with Kui Chai Pad Tub

• Jasmine rice (best pairing)
• Sticky rice (works well too)
• Rice porridge (jok) for a comfort-style meal
• Cucumber slices or light soup on the side

If you want to serve it Thai-restaurant style, plate it with rice and add a small dish of prik nam pla (chilies in fish sauce) on the side.

Nutrition values & benefits (with smart guidance)

Nutrition depends heavily on portion size and sauce amounts. Below is a realistic overview and a typical estimate for a serving when cooked with moderate oil and sauce.

Pork liver nutrition highlights

Pork liver is one of the most nutrient-dense foods you can eat. It commonly provides:

• High-quality protein
  Supports muscle maintenance and helps you feel full.
• Iron
  Liver is naturally rich in iron, which helps support oxygen transport in the blood. This is why many cultures consider liver “good for blood.”
• Vitamin A (very high)
  Liver is famous for vitamin A, important for vision, immune function, and skin.
  Note: because it can be very high, it’s smart to eat liver occasionally rather than daily.
• B vitamins (especially B12)
  Vitamin B12 supports energy metabolism and the nervous system. Many people low in B12 benefit from foods like liver.
• Copper and selenium
  Trace minerals that support immune health and antioxidant defenses.

Garlic & garlic chives benefits

• Garlic contains natural sulfur compounds that may support heart and immune health.
• Garlic chives provide:
• fiber (digestion support)
• vitamin C and antioxidants (small but helpful)
• freshness that balances rich proteins

Sauce considerations (oyster sauce + soy sauce)

These add incredible flavor but also add sodium. If you’re watching salt intake:

• use reduced-sodium soy sauce
• balance with more chives/veg
• don’t overdo the sauces

Typical estimated nutrition (per serving)

Rough estimate for 1 serving (about 150g cooked liver + chives, moderate oil):

• Calories: ~250–400
• Protein: ~25–35g
• Fat: ~10–20g
• Carbs: ~5–15g (mostly from sauces/sugar)

Smart portion tip

Because liver is extremely high in vitamin A and certain minerals, many people enjoy it 1–2 times per week, not every day. In Thai food culture, liver is often part of a rotation of dishes rather than a daily main protein.
