In a large pot, heat 1 tablespoon of olive oil over medium heat. Once hot, add the diced onion, sliced celery, and minced garlic and ginger. Sauté for about 5 minutes until the vegetables are softened and fragrant, stirring occasionally to prevent burning.
Next, stir in the sliced carrots, followed by the reduced-sodium chicken broth. The broth is the heart of this Chicken Pho Recipe, so be sure to use a quality option for the best flavor.
Add the fish sauce, cut lemongrass, star anise pods, and a few black peppercorns to the pot. Bring the mixture to a gentle simmer, allowing the flavors to meld together for about 20 minutes.
After 20 minutes, add the trimmed chicken thighs to the pot. Sprinkle the chicken with 1 tablespoon of Chinese five-spice and cook for an additional 15-20 minutes, or until the chicken is cooked through and tender.
While the chicken is cooking, prepare the rice noodles according to the package instructions. Drain and set aside.
Once the chicken is done, remove it from the pot and let it cool slightly. Shred the chicken into bite-sized pieces using two forks, then return it to the pot.
Stir in the juice of half a lime and adjust the seasoning with more fish sauce or sriracha according to your taste.
To serve, place a handful of cooked rice noodles in a bowl, ladle the hot broth and chicken over the noodles, and top with finely sliced mint, Thai basil, and cilantro. Enjoy your delicious bowl of Chicken Pho Recipe while it’s hot!
