Step 1

Melt butter over medium heat in a Dutch oven or stockpot. Add onion, celery, and carrots and cook until fragrant, approximately 4-5 minutes. Reduce heat to low. Add garlic, parsley, and poultry seasoning; cook for 1 minute, stirring constantly. Sprinkle in 1 1/2 tablespoon flour; cook for 1 minute, stirring constantly. Stir in chicken stock and bay leaf; simmer for 25 minutes.

Step 2

Remove the bay leaf. Season with salt and pepper to taste. Add chicken and frozen peas and simmer for an additional 5 minutes.

Step 3

In a medium bowl, mix 1 cup flour, baking powder, sugar, and salt. Cut in butter with a pastry cutter. When crumbly, add milk and stir just until combined. Drop by small spoonfuls into simmering soup. Cover and cook for 15 minutes without removing the lid.
