Start by placing the chicken breasts at the bottom of your crockpot. This allows the meat to absorb all the flavors from the ingredients that will be added on top. I always recommend trimming any excess fat beforehand—it helps the soup stay light but still rich in taste.
Pour the crushed tomatoes and chicken broth right over the chicken. The tomatoes provide that tangy base, while the broth keeps everything juicy and flavorful. I like using low-sodium broth so I can season to my liking later.
Sprinkle in the dried basil, oregano, garlic powder, onion powder, salt, and pepper. Give it a good stir to evenly distribute all the flavors. These Italian herbs bring the signature Chicken Parmesan taste we all love—savory, aromatic, and just a little peppery.
Cover your crockpot and cook on Low for 6–8 hours or High for 3–4 hours. The slow cooking ensures the chicken becomes tender and infused with the tomato-herb blend. Your kitchen will smell incredible while it simmers away!
Once cooked, remove the chicken breasts and shred them using two forks. The meat should fall apart easily. Return the shredded chicken back into the crockpot so it can soak up all that flavorful broth.
Now comes my favorite part—stir in the Parmesan and mozzarella cheeses. They melt beautifully into the soup, creating a creamy, velvety texture that feels indulgent but comforting.
If you want a heartier meal, stir in 2 cups of cooked pasta. I usually go for rotini or penne because they hold the cheesy broth perfectly. You can skip it for a lighter, low-carb version too.
Ladle the soup into bowls and top with fresh basil. The bright green adds freshness and that perfect finishing touch. Serve with garlic bread or a side salad for a complete meal.
