Pour in the chicken broth and add whole chicken breasts to the pot. Bring everything to a gentle simmer over medium-high heat, then reduce to medium-low, cover, and let it cook until the chicken reaches 165°F internally and the vegetables are tender - about 12-15 minutes.

Remove the cooked chicken breasts to a cutting board and shred them with two forks. Meanwhile, whisk the heavy cream and cornstarch together in a small bowl until smooth, then stir this mixture into the soup along with the gnocchi. Let everything simmer for 4-5 minutes until the gnocchi becomes tender and the broth thickens slightly.

Return the shredded chicken to the pot and add the chopped spinach and grated Parmesan. Stir gently until the spinach wilts and the cheese melts. Taste and adjust seasonings if needed before serving hot with crusty bread.
