Ingredients

Instructions

  1. Step 1: Cut 1.5 lbs boneless chicken breasts into 1-inch cubes and season with 1 tsp kosher salt and 1/2 tsp black pepper. Melt 2 tbsp butter in a large pot over medium heat until foaming.
  2. Step 2: Add chicken cubes and cook for 4 minutes until golden brown, stirring occasionally to prevent sticking.
  3. Step 3: Add 1 diced medium yellow onion and 2 cups sliced cremini mushrooms, cooking for 5 minutes until mushrooms release liquid and brown slightly.
  4. Step 4: Stir in 3 minced garlic cloves, 1 tbsp fresh thyme, 1 tbsp fresh rosemary, 1 tsp dried parsley, and 1 tsp lemon zest. Cook for 1 minute until fragrant.
  5. Step 5: Pour in 3 cups chicken broth and bring to a simmer. Cook uncovered for 8 minutes until chicken is fully cooked.
  6. Step 6: Stir in 1/2 cup heavy cream and simmer for 3 minutes until the soup thickens and coats the back of a spoon. Remove from heat.
  7. Step 7: Garnish with 2 tbsp chopped fresh chives before serving.
