1-Step 1: Prepare and Sear the Chicken Begin by seasoning your chicken pieces generously with salt and pepper on both sides. Heat 1 tablespoon of olive oil in a large soup pot or Dutch oven over medium-high heat. Once the oil shimmers, carefully place the chicken in the pot and sear for 3 minutes per side until lightly browned. Remove the chicken from the pot and let it rest on a cutting board for about 10 minutes. This resting period is crucial because it allows the juices to redistribute throughout the meat, ensuring juicy chicken pieces in your finished soup. After resting, dice the chicken into bite-sized pieces, discarding any bones.

2-Step 2: Build the Flavor Base In the same pot, melt 5 tablespoons of butter over medium heat. Use a wooden spoon to scrape up all that flavorful fond from the bottom of the pot – this is where so much flavor lives! Add the diced onion, carrots, and celery to the pot, stirring to coat in the butter. Sauté these vegetables for about 5 minutes until they begin to soften and the onions turn translucent. Next, stir in the minced garlic, Worcestershire sauce, hot sauce, and all the seasonings (onion powder, dried basil, parsley, thyme, rosemary, mustard powder, ground sage, and pepper). Cook this mixture for 1 minute, stirring constantly to prevent the garlic from burning. The aromatics will become incredibly fragrant, filling your kitchen with the promise of a delicious meal to come.

3-Step 3: Create the Thickened Broth Sprinkle the flour over the vegetable mixture and stir constantly for 2 minutes. This step cooks out the raw flour taste and creates a roux that will thicken your broth. The mixture should look slightly pasty and coat the vegetables. Now comes the important part: gradually add the chicken broth in small splashes while stirring constantly. This technique prevents lumps from forming. Use your spoon to scrape the bottom of the pot as you add liquid, incorporating all the flavorful bits. Once all the broth is incorporated, add the half and half in the same gradual manner. If using, drop in the chicken bouillon cube and stir until dissolved. Add the frozen peas to the pot and bring everything to a gentle boil, then reduce to a simmer. Let the soup cook uncovered for about 5 minutes to allow the flavors to meld and the broth to thicken slightly.

4-Step 4: Prepare the Dumpling Dough While the soup simmers, make the dumpling dough. In a medium bowl, whisk together the dry ingredients: flour, baking powder, baking soda, salt, garlic powder, and sugar. In a separate small bowl or measuring cup, combine the cold sour cream, cold milk, and melted butter. Pour the wet ingredients into the dry ingredients and fold gently just until combined. Be careful not to overmix – this is the key to tender, fluffy dumplings. The dough should be thick and slightly sticky, similar to biscuit dough.

5-Step 5: Cook the Dumplings Add the diced chicken back to the pot along with any accumulated juices. Reduce the heat to low – this is important for proper dumpling cooking. Using a small cookie scoop or two spoons, drop balls of dumpling dough evenly over the surface of the soup. Space them out so they have room to expand. Spoon a little of the hot liquid over each dumpling to help them start cooking. Cover the pot tightly with a lid and maintain a gentle simmer for exactly 15 minutes. Do not lift the lid during this time – the trapped steam is what cooks the dumplings to fluffy perfection. After 15 minutes, remove the lid and test a dumpling by inserting a toothpick into the center. If it comes out clean, your dumplings are done. Garnish with fresh parsley and serve immediately in warm bowls.
