Instructions
Peel and dice the carrots into 1/4-inch pieces, slice the celery into thin rounds, dice the onion, and mince the garlic. Keep all cuts uniform so the vegetables cook evenly.
Add the carrots, celery, onion, and garlic to the slow cooker, then lay the chicken breasts on top. Sprinkle with Italian seasoning, thyme, rosemary, salt, and pepper, add the bay leaf, and pour the chicken broth over everything.
Cover and cook on low for 6 to 7 hours, or on high for 3 to 4 hours, until the chicken reaches 165°F (74°C) and the vegetables are tender. Avoid lifting the lid during cooking.
Remove the chicken breasts with tongs and shred them into bite-sized pieces using two forks. Discard the bay leaf, then set the shredded chicken aside.
In a medium bowl, whisk together the cornstarch and cold water until completely smooth with no lumps. The water must be cold to prevent clumping.
Stir the heavy cream and cornstarch slurry into the slow cooker, then add the gnocchi and the shredded chicken. Cover and cook on high for 30 to 45 minutes until the gnocchi are tender and the broth has thickened.
Stir in the baby spinach until wilted, about 30 seconds, then add the Parmesan cheese and stir until melted. Taste and season with additional salt and pepper as needed.
Ladle the soup into bowls, topping each with extra Parmesan and a sprinkle of fresh parsley if desired. Serve immediately alongside crusty bread.
Notes
Never add gnocchi at the start: Potato gnocchi will turn to mush if cooked for hours. Always add them during the last 30 to 45 minutes of cooking.
Use cold water for the slurry: Warm or hot water causes cornstarch to clump. Always whisk it into cold water first before adding to the soup.
Chicken thigh substitution: Boneless, skinless chicken thighs can replace breasts for a richer, juicier soup with deeper flavor.
Lighter cream option: Swap heavy cream for evaporated milk to reduce fat while still achieving a creamy broth.
Use fresh spinach only: Frozen spinach releases excess water and can thin the broth. Fresh baby spinach wilts perfectly in seconds.
Grate your own Parmesan: Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly. A freshly grated block melts beautifully.
Make-ahead tip: Chop all vegetables and place them in the slow cooker insert the night before. Refrigerate overnight and add the broth and chicken in the morning.
Do not open the lid early: Each time the lid is removed, 20 to 30 minutes is added to the total cook time.
Storage: Refrigerate leftovers in an airtight container for up to 4 days. Freeze for up to 2 to 3 months, but consider leaving the gnocchi out before freezing and adding fresh ones when reheating.
Reheating: Warm on the stovetop over medium-low heat, stirring gently. Avoid high heat to prevent the cream from separating.
