In a large cooking pot, heat olive oil and add chicken and onion. Saute over medium heat for 5-7 minutes, until chicken is cooked through and onions are soft, stirring occasionally.
Add chicken broth, garlic & onion powder, parsley, basil, salt, pepper, chicken bouillon and vegetables. Simmer for about 5 minutes.
For the thickening mixture:
Meanwhile, in a separate medium mixing bowl whisk together milk and flour. Slowly pour into simmering stew, stirring constantly. Let simmer for 5 minutes.
For the Dumplings:
In the medium mixing bowl used for the thickening mixture (less dishes) combine flour, baking powder and salt. Stir in the milk and mix until just combined. Don’t overmix.
Turn heat to medium heat and give the stew a good stir. Wait until the stew is at a medium boil. Using a Tablespoon as a measure (I use a 1 Tablespoon cookie scoop), spoon dumpling dough into the boiling stew until the surface of the stew is covered in balls of dough.
Cover stew and dumplings with lid and cook for 8-9 minutes. Remove lid and test a dumpling with a fork. If it is still doughy, cover and cook for another 1-2 minutes.
Notes
This recipe is crock pot friendly!Simply mix all the stew and thickening ingredients into a crock-pot and cook on high for 4 hours. After 4 hours, mix together the dumpling dough and cook on high for another hour until dumplings are cooked through.
