Chicken: Rinse and pat dry the chicken pieces, trim any excess fat, and cut into uniform bite-sized pieces for even cooking.
Aromatics: Dice the onion and mince the garlic finely.
Building the Flavor Base:
Heat a drizzle of olive oil in a sauté pan over medium heat.
Add the diced onion and sauté until translucent (about 3-4 minutes).
Add the minced garlic and cook for another minute, stirring continuously to prevent burning.
Season lightly with salt, pepper, and red pepper flakes (if using).
Assembling in the Slow Cooker:
Transfer the sautéed onions and garlic to the bottom of the crock pot.
Add the chicken pieces evenly over the aromatics.
Pour in the diced tomatoes, chicken broth, and sprinkle in the Parmesan cheese.
If using, add the pasta at this stage.
Finally, sprinkle the Italian herb blend evenly over the contents.
Slow Cooking:
Cover the slow cooker with its lid.
Cook on low for 6–8 hours, or on high for 3–4 hours. Avoid lifting the lid frequently to maintain the necessary heat and moisture.
Finishing Touches:
A few minutes before serving, open the lid and stir in an additional portion of freshly grated Parmesan cheese.
Pour in the heavy cream to enhance the soup’s creamy consistency.
Mix gently to blend the flavors while preserving the texture of the chicken.
