Tips to make the best soba noodle chicken soup
- Don’t slice the mushrooms too thin, so they hold up to cooking and don’t break apart.
- Use a good beef broth. We add flavor with mushrooms, onions, garlic and soy sauce, but you want to start with a strong, good-quality broth.
- If you use a low sodium beef broth, you may need to add salt to taste.
- If the noodles start to get sticky, rinse them with cold water and they’ll get slippery again.

Poach the chicken breast
- Poached chicken is boneless, skinless chicken breasts or thighs that are simmered gently in liquid until the chicken is cooked through. The liquid used is usually water or broth and it’s flavored with aromatics, herbs and spices.
- Place the chicken in a medium saucepan that’s large enough so that they fit side by side without overlapping. Cover the chicken with 1 cup of beef broth and 1 cup of water; add a pinch of salt.
- Start the chicken on medium-high heat, and bring the broth to a simmer. As soon as the liquid starts simmering, lower the heat to medium-low and cover.
- Simmer the chicken gently for 15-20 minutes, or until the internal temperature of the thickest piece is at least 165°F. Remove the chicken breast from the poaching liquid and set it on a cutting board to cool a bit.
- Do not discard the cooking liquid. Strain the broth using a fine, mesh sieve and reserve it for the soup. When the chicken is cool enough to handle slice it to thin strips.
