Lao Khao Mee

Lao Pork Noodle Soup, Khao Mee Vientiane

This lao khao mee recipe makes Vientiane’s everyday noodle bowl: flat rice noodles tossed in a savoury pork sauce, then ladled with a light, clear pork broth — no coconut curry, just pork, bean sprouts, long beans and a pile of fresh herbs. One serving is about 475 g.

Khao mee is the everyday noodle bowl of Vientiane’s morning markets: flat rice noodles tossed in a savoury sauce with sliced pork, bean sprouts, long beans and fresh herbs, moistened with a little clear pork broth. It is different from its Lao neighbours — khao piak sen uses thick hand-cut rice and tapioca noodles in a chicken broth, and khao poon is a red-curry coconut-milk noodle soup served at celebrations. Khao mee stays light and clear, which is why it is an everyday bowl rather than a feast dish.

Pairs well with: Fresh herbs, lime & chilli oil

A good khao mee has glossy, separate noodles, tender sliced pork and a clear, lightly savoury broth — never a heavy or cloudy soup.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 55m
P

Prep Stage: Soak Noodles & Slice Vegetables

20 Mins • Knife Work

Soak the flat rice noodles in warm water until pliable, and get every topping ready before the broth simmers: bean sprouts rinsed, long beans cut, herbs washed and torn, spring onions sliced. Khao mee is assembled fast at the end, so nothing should be left to chop.

Maestro Tip: Do not soak the noodles until soft — they finish cooking in the hot broth and go mushy if they start out limp.

  1. 1

    Simmer the Pork and Broth

    25 Mins Gentle simmer, about 95°C (203°F); pork to 63°C (145°F)

    Put 400g of pork loin in a pot with 1.6 litres of cold water, bring to a gentle simmer and skim off any foam. Add 1g of black pepper and simmer for 20 to 25 minutes, until the pork reads 63°C (145°F) at the thickest part, then lift it out and rest it for 3 minutes.

    A bare simmer keeps the broth clear — never let it boil hard.

    Done when: The broth is clear and lightly savoury; the pork is juicy and reads 63°C (145°F).

  2. 2

    Slice the Pork and Season the Broth

    5 Mins Simmer, about 95°C (203°F)

    Slice the rested pork thinly across the grain. Season the broth with 30ml of fish sauce and 12g of sugar, tasting as you go — it should be savoury first, with a faint sweetness behind it.

    Slice thinly and across the grain so the pork stays tender in the bowl.

    Done when: A spoonful of broth tastes balanced, not salty; the pork slices are even and pink.

  3. 3

    Blanch the Long Beans and Noodles

    5 Mins Rolling boil, 100°C (212°F)

    Bring the broth to a rolling boil. Drop 100g of yardlong beans into the boiling broth for 1 minute, lift out and set aside. Then cook the soaked noodles in the same broth for 2 to 3 minutes until just tender, and drain well. While the noodles cook, heat 20ml of oil in a small pan and fry the minced garlic until golden, then set aside for the topping.

    Cook the noodles in the broth, not in plain water — they pick up flavour as they cook.

    Done when: The noodles are silky and springy, not mushy; the beans are bright green and crisp-tender.

  4. 4

    Toss the Noodles in Sauce

    5 Mins No heat — toss hot, about 80°C (175°F)

    Divide the hot noodles between 4 bowls. Spoon over 15ml of fish sauce and 15ml of light soy sauce, then toss each bowl with chopsticks so every strand is coated in the savoury sauce.

    Toss while the noodles are still steaming — cold noodles clump and will not take the sauce.

    Done when: Every strand is glossy and evenly seasoned.

  5. 5

    Assemble the Bowls

    5 Mins Broth at a rolling boil, 100°C (212°F)

    Top each bowl with sliced pork, blanched long beans and 150g of bean sprouts, then ladle over just enough boiling broth to moisten the noodles — about 150ml per bowl, not a full soup. Finish with fried garlic, spring onions, herbs, lime wedges and chilli flakes on the side.

    Ladle lightly: khao mee is a tossed noodle bowl with a little clear broth, not a drowned soup — that is what sets it apart from khao poon’s coconut curry broth.

    Done when: The bowl shows glossy noodles, pink pork, crisp sprouts and green herbs, with a shallow pool of clear broth.

Finishing Touches & Plating

Serve immediately with lime wedges, chilli flakes and the herb plate on the side, so each person seasons their own bowl. Fry the garlic in 20ml of oil until golden just before serving and spoon it over the top — it is the finishing touch that makes the bowl smell like a Vientiane morning market.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Vitamin C (bean sprouts, lime, herbs), vitamin A and folate (herbs, long beans), iron and zinc (pork), B vitamins (pork, noodles).

Light, Clear Broth

A clear pork broth with no coconut milk or heavy cream keeps the bowl fresh and easy to digest.

Protein and Steady Energy

About 29g of protein per serving with rice noodles for steady energy — a satisfying lunch without heaviness.

Fresh Herbs and Crunch

Bean sprouts, long beans and a pile of fresh herbs add fibre, crunch and vitamin C to every bowl.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Vegetables

Fresh Herb Plate & Lime

Mint, cilantro and basil with lime are the Lao way to finish a noodle bowl — the lime’s vitamin C also helps the body absorb iron from the pork.

Papaya Salad (Tam Mak Hoong)

A small, spicy-sour salad cuts through the savoury noodles and adds crunch.

Sides

Grilled Pork Skewers (Ping Moo)

A smoky skewer on the side doubles down on the pork theme and adds charred flavour to the mild bowl.

Drinks

Iced Lao Coffee

Strong, sweet Lao coffee is the classic market-stall companion to a morning noodle bowl.

Complete menu

Serve khao mee as the main bowl with a plate of fresh herbs, lime and chilli on the side, a grilled pork skewer to share, and iced Lao coffee to finish.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

A Rich Coconut Curry on the Side

Khao mee is deliberately light and clear; a heavy coconut curry alongside overwhelms the broth and doubles the fat. This is general information, not medical advice.

Leaving Cooked Noodles Sitting in Broth

Rice noodles keep absorbing liquid and turn mushy within minutes, so assemble and eat at once — do not hold the finished bowls. This is general information, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

  • General adultsA complete, balanced lunch — noodles, pork, vegetables and herbs in one bowl.
  • ChildrenSuitable with the chilli flakes left out and the pork sliced small; cut the noodles short for younger children.
  • ElderlySoft noodles, tender pork and warm broth — easy to eat; keep the chilli and fish sauce moderate.
  • Pregnant womenGenerally suitable; the pork is fully cooked to 63°C (145°F) with a 3-minute rest — keep the fish sauce moderate.
  • Breastfeeding womenGenerally suitable; the iron and protein support recovery — eat the full bowl with plenty of herbs.
  • AthletesA strong lunch after training: about 29g of protein with fast carbohydrate for glycogen.
  • Weight gainA good choice — eat the full bowl with extra pork and noodles, and add a grilled skewer on the side.
  • Weight lossChoose a smaller noodle portion, load up on bean sprouts and herbs, and go easy on the extra sauce.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesA serving carries about 79g of carbohydrate from the noodles; take a smaller noodle portion with extra bean sprouts, and ask your clinician about portions that fit your plan.
  • High blood pressureFish sauce and soy sauce make this a salty bowl; use less sauce, drink less of the broth, and ask your clinician if you follow a low-sodium plan.
  • Kidney diseaseThe broth and sauces are high in sodium and the pork adds potassium; limit the broth and ask your clinician about portion size.
  • GoutPork is moderate in purines; eat occasionally and in smaller portions, and ask your clinician about your overall diet.
  • Stomach issuesThe clear broth is usually gentle, but fresh chilli and raw onion can irritate a sensitive stomach; skip the chilli flakes and go easy on raw herbs, and ask your clinician if symptoms persist.
  • Cardiovascular diseaseThe broth is low in fat and the pork is lean loin; keep the fried garlic light and ask your clinician about how it fits your eating pattern.
  • Fatty liverKeep the portion modest and favour the vegetables and lean pork over extra noodles; ask your clinician about portions.
  • Food allergiesContains fish (fish sauce) and soy (soy sauce). The noodles are naturally gluten-free rice noodles — just confirm the fish sauce and soy sauce brands are certified gluten-free if you have coeliac disease. If you have a severe allergy, ask your clinician.
  • Special therapeutic dietsIf you follow a prescribed low-sodium or low-purine diet, use less fish sauce and soy sauce and a smaller pork portion, and check with your clinician.

If you have a medical condition, consult your doctor before changing your diet.
