Ingredients

  • 1.5 lb Chicken Drumettes (bone‑in, skin on; you can use large drumsticks instead)
  • 1 tbsp Fish Sauce (for marinating the chicken)
  • 6 cups Water (plain tap water)
  • 1 piece Onion (medium, quartered)
  • 3 stems Cilantro Stems (optional, for broth flavor)
  • 3 cloves Garlic Cloves (crushed)
  • 2 tbsp Soy Sauce (low‑sodium preferred)
  • 0.5 tsp Salt (adjust to taste after broth is seasoned)
  • 0.5 tsp White Pepper (ground) (adds subtle heat; you can add a little more at the end)
  • 2 pieces Russet Potatoes (peeled and cut into 1‑inch cubes; use waxy potatoes if you prefer firmer texture)
  • 2 pieces Roma Tomatoes (quartered; will soften and add a bright pop of colour)
  • 2 tbsp Fresh Cilantro Leaves (chopped, for garnish; substitute green onions if you dislike cilantro)

Instructions

  1. Marinate Chicken

    Place the chicken drumettes in a shallow bowl and coat evenly with fish sauce. Toss to ensure all pieces are covered and set aside while you prep the other ingredients.

    Time: PT5M

  2. Prep Aromatics

    Quarter the onion, crush the garlic cloves, and (optional) pull off 2‑3 cilantro stems. Set aside.

    Time: PT5M

  3. Prep Potatoes

    Peel the russet potatoes and cut into roughly 1‑inch cubes.

  4. Prep Tomatoes

    Quarter the roma tomatoes; no need to peel.

  5. Make the Broth

    In the large pot combine water, quartered onion, cilantro stems, crushed garlic, and soy sauce. Bring to a rolling boil over high heat.

    Time: PT5M

    Temperature: boiling

  6. Simmer Chicken

    Carefully add the marinated chicken to the boiling broth to avoid splatter. Reduce heat to a gentle simmer and cook for about 15 minutes, until the meat is tender and starts to fall off the bone.

    Time: PT15M

    Temperature: simmer

  7. Optional Skim

    If desired, use a skimmer to remove any floating impurities.

    Time: PT2M

  8. Add Potatoes

    Stir in the cubed potatoes and continue to simmer for about 8‑10 minutes, until they are just tender.

    Time: PT10M

    Temperature: simmer

  9. Add Tomatoes & White Pepper

    Add the quartered roma tomatoes and sprinkle ground white pepper. Gently stir and simmer for another 5 minutes until the tomatoes are soft and beginning to fall apart.

    Time: PT5M

    Temperature: simmer

  10. Season to Taste

    Taste the broth; add salt if needed. Adjust white pepper if you prefer more heat.

    Time: PT2M

  11. Finish and Serve

    Stir in chopped fresh cilantro (or green onions). Ladle the soup into bowls and serve hot, optionally over steamed rice.

    Time: PT3M

  • Stirring Spoon

Critical Steps — Do Not Skip

  • Marinating the chicken with fish sauce ensures early flavor penetration.
  • Simmering the bone‑in chicken long enough extracts a rich stock.
  • Adding potatoes at the right time prevents them from becoming mushy.
  • Stirring gently after adding tomatoes preserves their shape.

Chef Tips from the Video

  • Use a mix of drumettes and a few drumsticks for extra marrow and richer flavor.
  • For a clearer broth, strain through a fine‑mesh sieve before adding the potatoes.
  • A splash of lime juice just before serving adds a bright finish.

Troubleshooting

Broth tastes bland.

Add a little more fish sauce, soy sauce, or salt; let it simmer another 5 minutes.

Potatoes become mushy.

Cut potatoes into larger cubes or add them later in the cooking process.

Tomatoes disintegrate completely.

Add tomatoes later (last 3‑4 minutes) and stir gently.

Storage

Refrigerator: Store in an airtight container for up to 3 days.

Freezer: Freeze in freezer‑safe bags or containers for up to 2 months; thaw before reheating.

Room temperature: Do not store at room temperature; cool to room temp within 2 hours before refrigerating.

Make-Ahead Tips

  • Prepare the broth a day ahead and refrigerate; add chicken and vegetables just before serving.
  • Cook the chicken separately, shred, and store; combine with broth when reheating.
