Step-by-Step Instructions
Build the Aromatic Base
Melt butter in a large Dutch oven or soup pot over medium heat. Add chopped onion and cook, stirring occasionally, until just starting to brown, about 3-4 minutes.
Layer the Seasonings
Stir in minced garlic, Italian seasoning, salt, pepper, and chili flakes. Cook for 1 minute until fragrant, being careful not to burn the garlic.
Add Liquid and Protein
Stir in chicken broth, then add whole chicken breasts and chopped sun-dried tomatoes. The chicken will cook directly in the broth, infusing additional flavor.
Cook the Chicken
Increase heat to medium-high and bring to a simmer. Cover, reduce heat to medium-low, and cook for 12-15 minutes until chicken reaches 165°F internal temperature when checked with a meat thermometer.
Prepare the Pasta
Meanwhile, cook pasta in a separate pot of boiling salted water according to package directions. Drain and set aside.
Shred and Thicken
Remove cooked chicken from soup and shred with two forks. In a small bowl, whisk together half-and-half and cornstarch until smooth. Stir this mixture into the soup and cook for 1-2 minutes until slightly thickened.
Final Assembly
Return shredded chicken to the pot along with cooked pasta and chopped spinach. Heat through until spinach wilts and everything is warmed. Taste and adjust seasonings as needed.
Serve with Cheese
Ladle into bowls and top with dollops of ricotta, grated Parmesan, and shredded mozzarella as desired.
