Pour the chicken broth into a large pot and bring it to a gentle simmer over medium heat. Let it simmer for about 30 minutes to deepen the flavor.
While the broth simmers, use a sharp knife to chop the chicken thighs into bite-sized pieces. Set aside.
Once the broth has simmered, carefully transfer the chicken pieces into the pot. Cook for about 10 minutes, until the chicken is just cooked through and tender.
Meanwhile, zest one lemon and juice both lemons, straining out any seeds. In a small bowl, whisk together the lemon juice, zest, and honey until smooth and well combined.
Add the shredded chicken back into the broth, then pour in the lemon mixture. Bring the soup to a gentle simmer and cook for another 10 minutes, allowing the flavors to meld.
Taste the soup and season with salt and pepper as needed. The broth should be lively and bright, with a subtle sweetness from the honey.
Just before serving, stir in a drizzle of olive oil and sprinkle with chopped fresh herbs for color and freshness.
Ladle the hot soup into bowls, and enjoy the vibrant, comforting flavors with crusty bread or on its own.
