Add the chicken to a large pot with the olive oil, salt, and pepper. (You don't even need to season the chicken separately, just throw it all in.) Sauté over medium heat for about 7 minutes, stirring occasionally, until the chicken is golden and the juices run clear. The internal temperature should reach 165°F. Remove the chicken from the pot and set aside.
1½ lbs (680 g) chicken breast, 2 tbsps (30 ml) olive oil, ½ tsp (3 g) kosher salt, ½ tsp (1 g) black pepper
Add the onion, celery, carrots, and butter to the same pot. Cook for about 4 minutes, stirring often, until the onions are translucent and the vegetables begin to soften.
1 cup (150 g) chopped yellow onion, 2 celery stalks, 2 medium carrots, 2 tbsps (28 g) butter
Stir in the garlic and cook for another minute until fragrant. Sprinkle in the flour and stir constantly for one minute to coat the vegetables and form the base for the creamy broth.
4 cloves garlic, ¼ cup (30 g) all-purpose flour
Pour in the chicken broth and add the potatoes, Better Than Bouillon, thyme, rosemary, poultry seasoning, garlic powder, onion powder, and sage. Stir well to dissolve the bouillon and lift any browned bits from the bottom of the pot.
5 cups (1.2 L) low-sodium chicken broth, 2 cups (280 g) cubed Yukon Gold potatoes, 1 tbsp (18 g) Better Than Bouillon chicken base, 1 tsp (1 g) dried thyme leaves, ½ tsp (0.5 g) dried rosemary leaves, ½ tsp (0.5 g) dried poultry seasoning, ½ tsp (1 g) garlic powder, ½ tsp (1.5 g) onion powder, ¼ tsp (0.25 g) dried sage leaves
Bring the mixture to a gentle boil, then reduce the heat and let it simmer uncovered for about 30 minutes, or until the potatoes and carrots are tender enough to be pierced with a fork. The stew should start to thicken as the starch from the potatoes blends with the flour and stock.
Return the cooked chicken to the pot, then stir in the Parmesan and heavy cream. Simmer for another few minutes, just until everything is warmed through and the broth turns rich and creamy.
½ cup (50 g) grated Parmesan cheese, ¼ cup (60 ml) heavy cream
Taste and adjust seasoning if needed. Finish with chopped parsley before serving.
2 tbsps (8 g) chopped parsley
