Vietnamese Chicken Noodle Soup

This aromatic Vietnamese chicken noodle soup, known as Pho Ga, is a masterclass in building layers of complex flavour. The soul of this high-protein dish lies in its golden broth, which is infused with charred onions, fresh ginger, and a fragrant blend of star anise, cinnamon, and black cardamom. It is a light yet deeply satisfying meal that balances savoury depth with the bright, citrusy notes of fresh lime and traditional herbs.

Perfect for a restorative weekend lunch or a nutritious midweek dinner, this homemade soup is both comforting and naturally energising. By simmering the stock with toasted spices and tender chicken legs, you create a restaurant-quality base that far surpasses any shop-bought alternative. Serve it steaming hot in large bowls, piled high with fresh mung bean sprouts, Thai basil, and zingy pickled shallots for an authentic finish.

  • about 4)

  • 1/4 teaspoons Chinese five-spice powder

  • 1 teaspoon grated peeled ginger, plus one 4" piece ginger, peeled, halved lengthwise

  • 1 tablespoon kosher salt, plus more

  • 1 tablespoon sugar, plus more

  • 2 medium onions, peeled, halved through root

  • 2 6" pieces lemongrass, tough outer layer removed, stalk lightly smashed

  • 6 black cardamom pods, crushed

  • 4 whole star anise pods

  • 2 cinnamon sticks

  • 6 whole cloves

  • 1 tablespoon fish sauce

  • 450g dried wide rice noodles

  • 230g mung bean sprouts (about 2 cups)

  • Spicy Pickled Shallots , fresh tender herbs such as Thai basil, mint, or coriander), lime wedges (for serving)

Bring chicken, onion, carrots, celery, and 4.7L water to a boil in a large heavy pot. Reduce heat and simmer, skimming surface occasionally, until broth is flavorful and reduced by one-fourth, about 2 hours.

Strain stock through a fine-mesh sieve into a large bowl; discard solids. (You should have about 3.8L ). Let cool, then cover and chill.

DO AHEAD: Stock can be made 5 days ahead. Let cool, then cover and chill.

Rub chicken legs with five-spice powder, grated ginger, 1 tablespoon salt, and 1 tablespoon sugar; let sit 15 minutes.

Meanwhile, heat grill. Spread out halved ginger and onions on a rimmed baking sheet and grill, turning occasionally, until charred all over, 15–20 minutes. Add lemongrass, cardamom, star anise, cinnamon, and cloves to onions and ginger and grill until lightly charred and fragrant, about 1 minute.

Transfer onion mixture to a large heavy pot. Add chicken stock and fish sauce and bring to a boil. Add seasoned chicken, reduce heat, and simmer until chicken is just cooked through, 20–25 minutes.

Using tongs, transfer chicken to a plate. Let cool slightly, then remove skin and bones; discard. Shred meat. Continue to simmer broth until it reduces slightly and flavours concentrate, 50–60 minutes. Season with more salt and/or sugar, if desired. Strain into a large bowl or clean pot.

Cook noodles according to package directions. Using tongs or a spider, transfer noodles to a colander and run under cold water to stop cooking; set aside. (Keep pot of boiling water handy for reheating noodles.)

Just before serving, return noodle cooking water to a boil. Place noodles in a fine-mesh sieve and lower into hot water to reheat, 30 seconds.

Divide noodles among warm bowls and add shredded chicken and bean sprouts. Ladle hot broth over, dividing evenly. Serve with Spicy Pickled Shallots, herbs, and lime wedges for squeezing over.

DO AHEAD: Seasoned chicken broth can be made 2 days ahead. Let cool, then cover and chill. Bring to a boil before serving.
