This creamy Tuscan chicken soup is rich, savory, and packed with tender chicken, pasta shells, spinach, Parmesan, and sun-dried tomatoes. It is a cozy one-pot dinner with Italian-inspired flavor and a silky broth that feels hearty without being complicated.
Season the chicken with 1/2 tsp salt and pepper. Melt the butter in a large pot over medium-high heat, then sear the chicken for about 3 minutes on the first side and 2 minutes on the second side, until lightly golden. Transfer to a plate; the chicken does not need to be cooked through yet.
Reduce the heat to medium-low. Add the onion, garlic, and celery to the same pot and cook for about 3 minutes, stirring often, until the onion softens and the aromatics smell fragrant.
Increase the heat to high and pour in the Chardonnay. Scrape the bottom of the pot to loosen the browned bits, then simmer until the wine has reduced by about half.
Add the chicken stock, water, 1 tsp salt, and black pepper. Bring to a boil, then stir in the pasta shells. Cook according to the package directions, usually about 10 minutes, stirring occasionally so the pasta does not stick.
While the pasta cooks, cut the seared chicken into 1/2-inch pieces. Add the chicken back to the pot during the last few minutes of pasta cooking so it finishes cooking through in the soup.
When the pasta is tender and the chicken is cooked through, reduce the heat to low. Stir in the Parmesan until melted, then add the cornstarch slurry, cream, and baby spinach. Cook for about 1 minute, stirring gently, until the spinach wilts and the soup thickens slightly.
Ladle the soup into bowls and top with sun-dried tomato strips. For extra flavor, drizzle over a little oil from the sun-dried tomato jar before serving.
For leftovers, store the pasta separately from the soup when possible so it does not absorb too much liquid. Refrigerate in airtight containers and reheat gently over low heat, adding a splash of stock or water if needed.
Use boneless skinless chicken thighs for the juiciest result, or substitute chicken breast if preferred and avoid overcooking it. Dry white wine can replace Chardonnay; for an alcohol-free version, use extra chicken stock with a small squeeze of lemon. Add the cream over low heat and avoid boiling after it goes in, which helps keep the soup smooth. If making ahead, cook the pasta separately and add it to each bowl before serving.
