They absorb the flavorful broth while keeping the carbohydrate count low. - Fresh lime completely changes the bowl.
A squeeze right before serving brightens all the savory flavors. - The herbs make every bite feel fresh.
Cilantro, Thai basil, and green onion provide a beautiful contrast to the warm broth.

📝 Ingredients
Aromatic Broth
- 6 cups (1.4 L) low-sodium chicken broth
- 1 small yellow onion, halved
- 3 cloves garlic, lightly crushed
- 2-inch piece fresh ginger, sliced
- 2 star anise
- 1 cinnamon stick
- 1 teaspoon coriander seeds
- 1 tablespoon fish sauce
- 1 teaspoon low-sodium soy sauce or tamari
- ½ teaspoon salt, or to taste
- ½ teaspoon black pepper
Soup
- 450 g boneless, skinless chicken breast, thinly sliced
- 2 packs (400–500 g total) shirataki noodles, rinsed thoroughly
- 1 cup bean sprouts
- ½ cup sliced mushrooms
- ½ cup thinly sliced bok choy
- 2 green onions, sliced
- ¼ cup fresh cilantro
- ¼ cup Thai basil, torn
- 1 lime, cut into wedges
- 1 red chili, thinly sliced, optional
Ingredient notes: Shirataki noodles are extremely low in carbohydrates but should be rinsed thoroughly and briefly heated before adding to the soup to improve their texture and remove their characteristic aroma.
Directions
- Toast the aromatics — 5 minutes
Heat a large stockpot over medium heat. Add onion, garlic, ginger, star anise, cinnamon, and coriander seeds. Toast for approximately 3–5 minutes, stirring occasionally. Visual cue: The aromatics should become lightly browned and highly fragrant. - Build the broth — 2 minutes
Pour in the chicken broth. Add fish sauce, soy sauce, salt, and black pepper. - Simmer — 25 minutes
Bring the broth to a gentle boil over medium-high heat, then reduce to low heat. Cover partially and simmer for approximately 25 minutes. High-protein tip: Keeping the broth at a gentle simmer prevents the chicken from becoming tough later. - Strain the broth — 3 minutes
Remove the large aromatics and spices using a fine-mesh strainer. Return the clear broth to the pot. - Cook the vegetables — 3 minutes
Add mushrooms and bok choy. Simmer over medium heat for 2–3 minutes until slightly tender but still vibrant. - Add the chicken — 4–6 minutes
Add the thinly sliced chicken to the gently simmering broth. Cook for approximately 4–6 minutes, depending on thickness, until fully cooked. Visual cue: Chicken should be opaque throughout and reach a safe internal temperature. - Prepare the shirataki noodles — 2–3 minutes
Rinse the noodles thoroughly under cold water. Briefly simmer or dry-toast them according to the package instructions. - Assemble the bowls — 3 minutes
Divide noodles between four bowls. Add chicken and vegetables. Ladle the hot broth over everything. - Add fresh toppings — 2 minutes
Top with bean sprouts, cilantro, Thai basil, green onion, and sliced chili. - Finish with lime
Squeeze fresh lime juice over each bowl immediately before serving.
