Start by melting butter in a large stockpot over medium-high heat. Add your frozen mirepoix mix along with parsley, Italian seasoning, garlic powder, smoked paprika, thyme, salt, and pepper. Stir everything together and sauté for about 3-4 minutes until the vegetables start to soften. This creates a fragrant and flavorful foundation for the stew.
Next, pour in the chicken broth and cream of chicken soup. Whisk to combine them into a smooth, creamy broth. Add the shredded rotisserie chicken and stir well. Reduce the heat to a gentle simmer and allow the flavors to meld together while preparing the dumplings.
For the dumplings, whisk the flour, baking powder, and salt in a mixing bowl. Separately, melt the butter and mix it with the milk. Gradually pour the liquid into the dry ingredients while stirring to form a soft dough. Ensure the dough is smooth and lump-free.
Using a cookie scoop or a tablespoon, drop spoonfuls of the dumpling dough into the simmering pot. Cover the pot with a lid and cook on low heat without lifting the lid for 25 minutes. This ensures that the dumplings steam properly and turn fluffy. Once cooked, the dumplings should have absorbed some broth’s flavors, making them irresistibly tasty.
Ladle the chicken and dumplings into bowls, ensuring that each serving has a generous amount of stew and dumplings. Garnish with additional parsley for a fresh, vibrant finish. Serve immediately and enjoy the cozy, homemade flavors.
