Boneless skinless chicken breasts: They shred beautifully after slow cooking and soak up all that savory flavor.
Minced garlic: Fresh or jarred — both work, but fresh packs more punch if you’re up for it.
Dried minced onion flakes: Adds that subtle sweetness and depth without needing to sauté.
Italian seasoning: This classic herb mix ties every ingredient together with an unmistakable Italian flair.
Tomato paste: Essential for that rich, thick tomato base that’s anything but watery.
Tomato sauce: Smooth and savory, it blends beautifully into the broth.
Diced tomatoes: Adds texture and bursts of fresh tomato flavor in every spoonful.
Chicken broth: The base that keeps things juicy and flavorful instead of heavy cream or water.
Spaghetti sauce (jarred): Another layer of flavor, plus an easy shortcut to bring in extra herbs and seasoning.
Grated parmesan cheese: The star for that salty, umami finish that makes you want seconds.
Campanelle pasta: I love this pasta’s shape — it holds the soup perfectly. You can swap for rotini or penne if needed.

Cheese Variety: Swap out part of the parmesan for mozzarella or fontina, either stirred in or sprinkled on top just before serving for gooey goodness.
Low-Carb Option: Leave the pasta out and serve the soup over sautéed zucchini noodles or spaghetti squash for a lighter meal.

How to Make Slow Cooker Chicken Parmesan Soup Recipe

Step 1: Combine All Ingredients (Except Pasta) in Your Slow Cooker

I love starting this soup by simply dumping the chicken breasts, garlic, onion flakes, Italian seasoning, tomato paste, tomato sauce, diced tomatoes, chicken broth, and jarred spaghetti sauce right into my 6-quart slow cooker. Give everything a good stir so those flavors start melting together early. This is where the magic begins! Cover it, set it to LOW, and let it cook gently for 6 to 8 hours. It’s perfect for throwing in the morning and coming home to a kitchen filled with incredible aromas.

Step 2: Shred the Chicken

When the cooking time is up, carefully remove the chicken breasts with tongs or a slotted spoon and shred them using two forks. I find shredding while the chicken is hot is easier and yields nice, tender strands. Add the shredded chicken right back into the slow cooker to soak up even more flavor.

Step 3: Stir in Parmesan and Pasta, Then Finish Cooking

Now, sprinkle in your grated parmesan cheese and add the campanelle pasta. Give everything a big stir to combine. Switch the slow cooker to HIGH and cook for about 15 to 20 minutes more—this is when the pasta cooks through right in the soup, soaking in all those Italian flavors. Keep an eye on it after 15 minutes; you want the pasta tender but not mushy.

Pro Tips for Making Slow Cooker Chicken Parmesan Soup Recipe

Use Thick Tomato Paste: This helps give your soup a rich, velvety texture that really mimics classic Chicken Parmesan sauce.
Add Pasta Last Minute: Cooking pasta too long in the slow cooker can turn it gummy; adding it near the end keeps it perfectly al dente.
Shred While Hot: Chicken shreds much more easily when it’s fresh out of the slow cooker—don’t wait for it to cool.
Don’t Skip the Parmesan: It’s the umami bomb that ties everything together—without it, the soup feels incomplete.

Garnishes

My go-to garnish combo for this soup is a sprinkle of freshly shredded mozzarella and a dollop of ricotta cheese right on top—it melts beautifully and adds that luscious creaminess I crave. A few fresh basil leaves or chopped parsley bring freshness and a pop of color. And of course, a light dusting of extra parmesan never hurts!

Side Dishes

Hands down, a crisp piece of crusty garlic bread is my favorite side—it’s perfect for dunking and soaking up every last drop of that tomatoey goodness. I also like serving a simple Caesar salad or a green side salad tossed with vinaigrette to lighten up the meal.

Creative Ways to Present

For a special dinner, I’ve ladled the soup into individual small ramekins, topped each with mozzarella and popped them under the broiler until bubbly and golden. It feels festive and restaurant-worthy but super easy! You can also serve the soup over garlic toasted baguette slices for a fun twist.

Make Ahead and Storage

Storing Leftovers

After enjoying a big batch, I usually let the soup cool to room temperature and transfer it to airtight containers for the fridge. It keeps beautifully for up to 3 days. The flavors actually deepen overnight, so leftovers taste even better!

Freezing

I’ve frozen this soup successfully several times. For best results, I like to freeze it before adding pasta—it can get a bit mushy during freezing. Then, when you reheat, just cook fresh pasta separately and combine. If you must freeze it with pasta, expect a softer texture but still tasty.

Reheating

Reheat gently on the stovetop over medium-low heat, stirring occasionally to prevent sticking. If the soup is too thick, adding a splash of chicken broth or water helps loosen it up. For individual portions, microwaving works fine—just cover and heat in short intervals, stirring in between.

FAQs

Can I use frozen chicken breasts for this soup?

Absolutely! Just be sure to add extra cooking time—an hour or so on low should do it—since frozen chicken takes longer to cook through in the slow cooker.
What can I substitute for campanelle pasta?

Any small pasta shape works well here, like rotini, penne, or mini shells. Just keep an eye on cooking times as they vary slightly.
Is it possible to make this soup in an Instant Pot?

Yes! You can use the sauté function to brown your garlic and onions first, then pressure cook all ingredients (except pasta) on high for about 15 minutes. Add pasta last and cook on sauté mode until tender.
Can I make this soup ahead of time?

Definitely! You can prepare it a day ahead and refrigerate. Just add pasta fresh when reheating so it doesn’t overcook and get mushy.
