The tomatoes cover the chicken almost as soon as it settles into the slow cooker, and by the end of the day the pot smells warm with garlic and Italian seasoning. I make Crockpot Chicken Parmesan Soup when I want the familiar tomato-and-cheese comfort of chicken Parmesan in a bowl, without breading or frying chicken. The chicken cooks right in the tomato broth, so there’s no separate pan to clean.
Once the chicken is tender enough to shred, I stir it back into the soup with cream and Parmesan. The pasta cooks in its own pot, then goes into the bowls before the soup is ladled over it. That keeps the tomato broth rich and spoonable, with mozzarella melting on top and fresh basil bringing a bright finish.
Kitchen Note
Finely grated Parmesan melts into the tomato base more readily than coarse shreds. Keep it fine, then give the soup its full low-heat finish so the cheese has time to melt in.
Save Crockpot Chicken Parmesan Soup for a cozy dinner with tender shredded chicken, a rich tomato broth, and a cheesy basil finish.
Why the Pasta Goes in the Bowl, Not the Slow Cooker
Small pasta needs just a few minutes in boiling water, while the chicken and tomato base need hours in the slow cooker. Add pasta at the beginning and it would sit in hot liquid long after it reached al dente, swelling and turning soft. It would also soak up some of the broth as it cooks, changing the balance of the soup.
Cooking the pasta separately gives you a better texture in every bowl. You can portion it out first, then ladle the soup over it so the noodles are coated without taking over the broth. It also gives you control over how much pasta goes into each serving, which is especially handy when everyone wants a different ratio of noodles to soup.
The Tomato Base, Parmesan, and Pasta Each Have a Job
- Crushed tomatoes and tomato sauce — Crushed tomatoes bring a bit of texture, while tomato sauce fills in the base with a smoother consistency. A value-brand can of each works well; choose plain tomatoes rather than a pre-seasoned sauce so the Italian seasoning and salt stay in balance.
- Onion, garlic, and Italian seasoning — Finely chopped onion softens into the broth as it cooks, and minced garlic spreads through the tomato base. Chop the onion evenly so you don’t end up with large, firm pieces after the slow cook.
- Low-sodium chicken broth — This gives the soup enough liquid to cook the chicken while leaving room to season the tomato base with kosher salt. Broth quality matters less than choosing low-sodium, which keeps the soup from getting overly salty as it cooks.
- Chicken breasts — Boneless, skinless breasts are easy to shred back into the soup and keep the bowl lighter than dark meat. Use thawed chicken so it cooks on the intended slow-cooker schedule.
- Heavy cream and Parmesan — Cream softens the acidity of the tomatoes, and Parmesan adds a savory, nutty note. A good block of Parmesan is worth using here, though a grocery-store wedge works perfectly well.
- Small pasta, mozzarella, and basil — Rotini and ditalini are both good small shapes; rotini has spirals, while ditalini makes each spoonful feel more even. Low-moisture mozzarella melts over the hot soup without adding the extra water that fresh mozzarella can release. Fresh basil gives the finished bowl a clean, fragrant lift.
Build the Soup in Three Stages for Tender Chicken and a Smooth Finish
Start the Tomato Broth Around the Chicken
Add the chopped onion, minced garlic, crushed tomatoes, tomato sauce, low-sodium chicken broth, Italian seasoning, kosher salt, black pepper, and red pepper flakes to a 6-quart slow cooker. Stir to combine, then nestle the thawed chicken breasts into the mixture. Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours. Check the thickest part of the chicken with a thermometer; it should reach 165°F before you move on.
Shred the Chicken and Finish the Soup
Transfer the cooked chicken to a cutting board and shred it with two forks. Return the shredded chicken to the slow cooker and stir in the heavy cream and Parmesan. Cover and cook on LOW for 10 to 15 minutes, until the cheese has melted. If you still see unmelted cheese, give it a little more time on LOW rather than turning the heat up.
Cook the Pasta and Fill the Bowls
Bring 2 quarts of water to a boil in a large pot, then add the pasta. Cook it according to the package directions until al dente, and drain it well. Divide the pasta among 6 bowls and ladle the soup over it. Finish each bowl with shredded low-moisture mozzarella and chopped fresh basil.
Easy Ways to Change the Bowl Without Losing Its Character
Pick rotini or ditalini for a different bite
Use either small pasta shape in the same amount. Rotini gives you spirals that catch some of the tomato broth; ditalini makes a tidier, spoon-friendly bite. The soup itself stays the same.
Leave out the red pepper flakes for a milder soup
Skip the red pepper flakes if you want the tomatoes, Parmesan, and basil to lead without a little heat in the background. The soup will still have plenty of savory flavor from the garlic and Italian seasoning.
Use gluten-free small pasta
For a gluten-free bowl, replace the regular pasta with the same amount of gluten-free small pasta and cook it according to its package directions. Gluten-free shapes can soften quickly, so check them as they cook and drain as soon as they’re al dente.
Storage and Reheating
- Refrigerator: Store the soup and cooked pasta in separate airtight containers for 3 to 4 days. Pasta left in the soup will soften as it sits.
- Freezer: Freeze the soup without pasta for up to 3 months. The cream may separate a little after thawing, but stirring as it warms helps bring the soup back together.
- Reheating: Warm the soup gently in a saucepan over medium-low heat, stirring until hot, and add it to freshly reheated or freshly cooked pasta. Avoid boiling the soup, which can make the cream separate.
