Cook the Chicken: Add the diced chicken to the pot, season with salt, pepper, thyme, and rosemary. Cook for about 5-6 minutes until the chicken is no longer pink.
Add Stock and Simmer: Pour in the chicken broth and bring to a boil. Reduce the heat to a simmer and let it cook for about 15-20 minutes, allowing the flavors to meld together.
Make the Dumplings: While the soup is simmering, in a separate bowl, whisk together the flour, baking powder, and salt for the dumplings. In another bowl, whisk together the milk and melted butter. Pour the wet ingredients into the dry ingredients and stir until just combined; be careful not to over-mix.
Incorporate Peas: Stir the frozen peas into the soup.
Drop the Dumplings: Using a tablespoon, drop spoonfuls of the dumpling batter gently into the simmering soup. You can fit about 8-10 dumplings in the pot, depending on their size.
Cover and Cook: Cover the pot and let the dumplings steam in the soup for about 15 minutes. Avoid lifting the lid during this time to allow proper steaming.
Finish and Serve: Once the dumplings are puffed and cooked through, taste the soup and adjust the seasoning as needed. Ladle the soup into bowls, garnish with fresh parsley, and enjoy the warm comfort of your chicken and dumpling delight!
