Ingredients:
- 900g (2 lbs) boneless, skinless chicken thighs
- 800ml (28 oz) crushed fire-roasted tomatoes
- 1L (4 cups) low-sodium chicken broth
- 30g (2 tbsp) tomato paste
- 1 large yellow onion, finely diced
- 4 cloves garlic, minced
- 15g (1 tbsp) Italian seasoning
- 240ml (1 cup) heavy cream
- 100g (1 cup) freshly grated Parmesan cheese
- 1 Parmesan rind
- 150g (1 cup) shredded mozzarella cheese
- Fresh basil or parsley for garnish
Instructions:
- Place chicken thighs at the bottom of a 6-quart slow cooker. Add diced onions, minced garlic, tomato paste, and Italian seasoning.
- Pour crushed tomatoes and chicken broth over the ingredients. Submerge the Parmesan rind into the center of the liquid.
- Cover and cook on Low for 6–7 hours (or High for 3–4 hours) until the chicken is tender.
- Remove the chicken thighs and the Parmesan rind. Shred the chicken using two forks and return it to the pot.
- Temper the heavy cream by whisking 1/2 cup of the hot broth into the cream in a separate bowl, then pour the mixture into the slow cooker.
- Stir in the grated Parmesan and shredded mozzarella until melted and the soup is velvety. Garnish with fresh herbs before serving.
