Pat your chicken dry using a paper towel then generously season the chicken with sea salt and pepper.
Heat 1 Tablespoon of butter in a large stock pot over medium heat. Sear your chicken until golden brown on both sides, then set aside on a plate.
Add the remaining tablespoon of butter and sauté the onion, carrots, celery, bell pepper, and garlic for 4-5 minutes. Stir in the Italian seasoning and bay leaf.
Stir in your broth and your brown rice then return the chicken back to the pot.
Bring your soup to a boil then reduce the heat and simmer for 35-40 minutes, or until the rice is tender and chicken is cooked through and falling apart.
Remove the chicken and bay leaf from the soup and carefully shred chicken with a fork. Discard the bay leaf.
Return your shredded chicken back into the soup then stir in your fresh lemon juice, zest, and parsley.
Serve soup while hot and enjoy!
