Sear the Chicken
Season the chicken with salt and pepper. Heat olive oil in a soup pot over medium-high heat and sear the chicken for about 3 minutes per side until lightly browned. Let rest for 10 minutes, then cut into bite-size pieces and discard bones.
Prepare the Soup Base
Melt butter in the same pot. Add onion, carrots, and celery and cook for about 5 minutes until softened.
Add garlic, Worcestershire sauce, hot sauce, and seasonings. Cook for another minute until fragrant.
Sprinkle flour over the vegetables and stir continuously for 2 minutes to create a roux.
Gradually pour in chicken broth while stirring. Add half and half and bouillon cube if using.
Stir in frozen peas and bring to a gentle simmer.
Make the Dumplings
In a bowl, combine flour, baking powder, baking soda, salt, garlic powder, and sugar.
Add sour cream, milk, and melted butter. Mix gently until a soft dough forms.
Return the chicken to the soup pot and stir gently.
Drop spoonfuls of dumpling dough evenly across the soup surface.
Cover the pot tightly and simmer for 15 minutes without lifting the lid so the dumplings steam properly.
Check a dumpling with a toothpick. If it comes out clean, the dumplings are done.
Garnish with parsley and serve the comforting Chicken and Dumplings Recipe hot.
