Overview

Lo Mein

Lao Mian, Tossed Noodles

This lo mein recipe boils soft egg noodles, then tosses them in a hot wok with velveted pork, cabbage, carrots, broccoli, peppers and mushrooms in a glossy soy and oyster sauce. The noodles stay soft and saucy — never crisped — which is what makes lo mein different from chow mein. One serving is about 445 g.

Lo mein — lao mian, tossed noodles — is the Cantonese answer to a quick wok dinner: the noodles are boiled separately and then tossed in sauce with meat and vegetables, so they stay soft and glossy instead of crisping in the pan. That is the whole difference from chow mein, where the noodles are fried. Lo mein travelled out of Guangdong with Cantonese cooks and became a takeaway staple around the world, while keeping its soft, saucy character.

Pairs well with: Chilli oil and a smashed cucumber salad

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 35m
P

Prep Stage: Velvet the Pork and Line Up the Wok

20 Mins • Slice + Mix Sauce

Slice the 350 g pork loin thinly against the grain and toss it with the 10 g cornstarch and 15 g Shaoxing wine; leave it to velvet for 10 minutes. Cook the 320 g noodles until just tender, drain and toss with a teaspoon of the vegetable oil. Shred the 150 g cabbage, julienne the 100 g carrots, cut the 120 g broccoli into small florets, slice the 100 g pepper, 100 g mushrooms, 40 g spring onions, 12 g garlic and 10 g ginger. Stir the 30 g light soy sauce, 10 g dark soy sauce, 20 g oyster sauce and 10 g sugar together.

Maestro Tip: Velveting the pork in cornstarch is what keeps it silky in the hot wok.

  1. 1

    Cook the Noodles

    8 Mins Boiling water, 100°C (212°F)

    Boil the 320 g noodles in a large pot of water for 1 minute less than the packet says, until just tender with a little bite. Drain, rinse briefly under cold water, and toss with a teaspoon of the vegetable oil so the strands stay separate.

    Rinsing stops the cooking — skip it and the noodles turn to mush in the wok.

    Done when: Springy strands, just tender, lightly oiled and separate.

  2. 2

    Sear the Pork

    4 Mins High heat, about 200°C (400°F)

    Heat the remaining vegetable oil in a wok or large pan over high heat until it shimmers. Add the 350 g velveted pork in a single layer and fry for 1 minute without moving it, then toss for 2 minutes until browned at the edges and cooked through to 71°C (160°F). Lift out and set aside.

    A crowded wok steams the pork instead of searing it — cook in two batches if needed.

    Done when: Pork browned at the edges, no pink, 71°C (160°F) inside.

  3. 3

    Stir-Fry the Vegetables

    4 Mins High heat, about 200°C (400°F)

    Add the 12 g garlic and 10 g ginger to the hot wok and fry for 30 seconds until fragrant. Add the 150 g cabbage, 100 g carrots, 120 g broccoli, 100 g pepper and 100 g mushrooms and stir-fry for 2–3 minutes until bright and just tender.

    Keep the vegetables moving — they should stay bright and crunchy, not stewed.

    Done when: Vegetables bright, just tender, still crunchy.

  4. 4

    Toss the Noodles in the Sauce

    3 Mins High heat, about 200°C (400°F)

    Return the pork to the wok, add the drained noodles and pour over the sauce. Toss everything together for 2 minutes until the noodles are glossy and evenly coated and the sauce clings to every strand. The noodles are tossed, not fried — they should stay soft and saucy, never crisp.

    Use tongs and lift the noodles from underneath, so the sauce coats evenly without breaking the strands.

    Done when: Noodles glossy and soft, sauce clinging, pork and vegetables mixed through.

  5. 5

    Finish with Sesame Oil

    1 Min Off the heat, cooling from about 200°C (400°F)

    Take the wok off the heat, drizzle over the 14 g sesame oil and the 40 g spring onions and toss once. Serve at once in warm bowls, with chilli oil on the side.

    Sesame oil goes in off the heat — boiling it kills the aroma.

    Done when: Glossy noodles, nutty aroma, vegetables still crunchy.

Finishing Touches & Plating

Serve the lo mein straight from the wok in warm bowls, while the noodles are still soft, glossy and steaming, with chilli oil on the side.

Vitamins & minerals: Provides niacin and thiamin from the pork, vitamin C from the peppers and broccoli, and vitamin A from the carrots.

High in Protein

About 33.9 g of protein per serving from the pork and egg noodles, so this is a filling dinner that keeps you going.

Five Vegetables in One Wok

Cabbage, carrots, broccoli, peppers and mushrooms bring fibre, vitamin C and vitamin A — about 6.3 g of fibre per serving.

Cooked Fast, Kept Fresh

The vegetables spend only minutes in the wok, so they keep their crunch, colour and most of their vitamins.

Food Pairings

What to Eat With

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

Vegetables

Smashed Cucumber Salad

Cold, garlicky cucumber is the classic cool counterpoint to hot, savoury sauced noodles.

Sides

Spring Rolls

Crisp vegetable spring rolls on the side add crunch to a soft noodle dish and keep the meal in the Chinese restaurant register.

Soups

Egg Drop Soup

A small bowl of egg drop soup on the side adds warmth without doubling the noodles.

Drinks

Chilli Oil and Iced Tea

Chilli oil on the side lets each person set their own heat, and cold unsweetened tea cools the wok's warmth.

Complete menu

Serve the lo mein with a smashed cucumber salad and a bowl of egg drop soup for a complete Chinese restaurant-style dinner.

Digestive Guardrails

What NOT to Combine

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

Frying the Noodles Crisp

Lo mein noodles are tossed in sauce, never fried crisp — frying them turns the dish into chow mein and the sauce will not cling. Keep the noodles soft. This is general food information, not medical advice.

Undercooked Pork

Pork must reach 71°C (160°F) all the way through — check the thickest slice with a thermometer before serving. This is general food 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 filling dinner with about 33.9 g of protein per serving — enjoy one bowl with a cucumber salad.
  • ChildrenMild as written and fun to eat with chopsticks; cut the noodles short for young children and leave the chilli oil off their portion.
  • ElderlySoft noodles and tender pork suit older eaters; keep the vegetables cut small and the portion moderate.
  • Pregnant womenFine when the pork is cooked right through to 71°C (160°F); keep the soy sauce as written and skip extra salt. Ask your clinician about portions.
  • Breastfeeding womenA protein-rich, energy-giving dinner; one bowl with soup is plenty. Ask your clinician about portions.
  • AthletesAbout 33.9 g of protein and 578 kcal per serving make it good recovery food — serve with a generous portion of vegetables.
  • Weight gainAt about 578 kcal with plenty of protein it suits weight gain when served as a full portion.
  • Weight lossAt about 578 kcal a serving it is on the heavier side for weight loss — take a smaller portion and load the bowl with extra vegetables.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesNoodles are the main carbohydrate at about 74.2 g per serving — keep to one serving and ask your clinician about portion size.
  • High blood pressureOne serving carries about 814 mg of sodium, mostly from soy sauce and oyster sauce — do not add extra soy sauce at the table. Ask your clinician about portions.
  • Kidney diseasePortions should stay modest, and the salt and protein content matter for some kidney diets. Ask your clinician about portions.
  • GoutPork contributes purines, so keep to one modest serving and drink water with the meal. Ask your clinician.
  • Stomach issuesSaucy noodles and soy sauce can feel heavy on a sensitive stomach; eat a smaller portion and keep the chilli oil off. Ask your clinician.
  • Cardiovascular diseaseModerate in fat and high in vegetables, which suits a heart-friendly meal — the sodium is the part to watch. Ask your clinician.
  • Fatty liverAbout 16.5 g of fat per serving with plenty of vegetables, so it fits a liver-friendly meal well. Ask your clinician.
  • Food allergiesContains wheat (gluten) and egg in the noodles, soy in the sauces, sesame oil, and mollusc in the oyster sauce — anyone with a wheat, egg, soy, sesame or shellfish allergy must check every sauce.
  • Special therapeutic dietsHigh in carbohydrate and protein with wheat gluten and soy — check the noodles and the sauces against your diet plan and ask your clinician.

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