Ingredients for Slow Cooker Chicken Parm Soup
For the Soup Base:
- 2 pounds boneless, skinless chicken breasts – The star protein that becomes wonderfully tender during slow cooking. You can substitute chicken thighs for even more flavor and moisture if you prefer.
- 1 large onion, diced – Creates the aromatic foundation of our Slow Cooker Chicken Parm Soup. Sweet onions work particularly well here, but yellow onions are perfectly fine too.
- 4 cloves garlic, minced – Fresh garlic provides that irreplaceable depth of flavor. In a pinch, 1 teaspoon of garlic powder can work, but fresh will give you the most vibrant result.
- 2 tablespoons olive oil – Use a good quality extra virgin olive oil if possible; it adds authentic Italian character to your Slow Cooker Chicken Parm Soup.
- 2 cans (28 oz each) crushed tomatoes – San Marzano tomatoes are worth the splurge here if you can find them, as they have the perfect balance of sweetness and acidity.
- 4 cups chicken broth – Homemade is wonderful, but a good quality low-sodium store-bought broth works beautifully too.
- 1 cup tomato sauce – This adds concentrated tomato flavor and helps thicken the soup.
- 2 teaspoons Italian seasoning – A convenient blend, but you can also use a combination of dried basil, oregano, thyme, and rosemary if you prefer.
- 1 teaspoon red pepper flakes – Adds a gentle heat that balances the richness. Adjust according to your spice preference.
- 2 bay leaves – These add a subtle depth that ties all the flavors together.
- 1 tablespoon balsamic vinegar – The secret ingredient that adds complexity and brightens all the flavors.
- 1 teaspoon sugar – Balances the acidity of the tomatoes. You can omit or substitute with a pinch of cinnamon for a unique twist.
- Salt and black pepper to taste – Diamond Crystal kosher salt works best for seasoning throughout the cooking process.
For the Cheese Component:
- 1½ cups shredded mozzarella cheese – A good quality low-moisture mozzarella provides the perfect melt. For dairy-free options, several plant-based mozzarella alternatives now melt surprisingly well.
- ½ cup grated Parmesan cheese – Adds that distinctive sharp, nutty flavor essential to chicken parmesan. Aged Parmigiano-Reggiano will give the most complex flavor.
For Serving:
- 1 cup panko breadcrumbs, toasted – These provide the crispy element that mimics the breading on traditional chicken parmesan. Gluten-free panko works well for those with restrictions.
- ¼ cup fresh basil, chopped – Adds a bright, aromatic finish that elevates the entire dish.
- Crusty bread or garlic bread – Optional but highly recommended for dipping!
How to Make Slow Cooker Chicken Parm Soup
Step 1: Prepare the Chicken and Aromatics
- Season your chicken breasts generously with salt and black pepper on both sides. This initial seasoning layer is crucial for well-developed flavor in your Slow Cooker Chicken Parm Soup.
- Heat olive oil in a large skillet over medium-high heat until it shimmers slightly. Add the chicken breasts and sear for 2-3 minutes per side until they develop a golden-brown color. They don’t need to be cooked through – you’re just building flavor at this stage. The chicken should release easily from the pan when it’s ready to flip.
- Transfer the seared chicken to your slow cooker. In the same skillet, add the diced onions and cook for 3-4 minutes until they begin to soften and turn translucent around the edges. Add the minced garlic and cook for another 30 seconds until fragrant but not browned – when you can smell the garlic, it’s time to move to the next step.
Step 2: Build Your Soup Base
- Transfer the sautéed onions and garlic to your slow cooker, scraping all the flavorful bits from the pan.
- Add the crushed tomatoes, chicken broth, tomato sauce, Italian seasoning, red pepper flakes, bay leaves, balsamic vinegar, and sugar to the slow cooker. Stir gently to combine everything without disturbing the chicken too much.
- Cover and cook on low for 6-7 hours or on high for 3-4 hours. The soup is ready when the chicken is tender enough to be easily shredded with two forks. The longer cooking time on low heat yields the most tender results for your Slow Cooker Chicken Parm Soup.
Step 3: Finish the Soup
- About 30 minutes before serving, remove the chicken from the slow cooker and place it on a cutting board. Using two forks, shred the chicken into bite-sized pieces – they should pull apart effortlessly if properly cooked.
- Return the shredded chicken to the slow cooker and stir to incorporate. Remove and discard the bay leaves.
- Taste the soup and adjust seasonings as needed. The flavor should be rich and savory with a balanced tomato acidity. This is your last chance to perfect the base of your Slow Cooker Chicken Parm Soup before adding the cheese elements.
Step 4: Add the Cheese Layer
- Sprinkle half of the mozzarella cheese and half of the Parmesan directly into the soup and stir until melted and incorporated. This creates a creamy, cheesy body throughout the soup.
- For serving, ladle the hot Slow Cooker Chicken Parm Soup into oven-safe bowls if you want the full chicken parmesan experience. Top each bowl with a portion of the remaining mozzarella and Parmesan.
- Place the bowls under the broiler for 2-3 minutes until the cheese is bubbly and developing golden spots. Watch carefully to prevent burning! The cheese should stretch beautifully when you dip your spoon in.
Step 5: Final Touches
- Top each bowl with a generous sprinkle of toasted panko breadcrumbs. They’ll begin to absorb the soup slightly while maintaining some crunch, mimicking that perfect chicken parm coating.
- Finish with freshly chopped basil, which adds color and a fresh aromatic element that balances the rich, slow-cooked flavors of your Slow Cooker Chicken Parm Soup.
- Serve immediately with crusty bread on the side for dipping into that flavorful broth.
Creative Variations for Slow Cooker Chicken Parm Soup
1. Creamy Chicken Parm Soup
Transform your Slow Cooker Chicken Parm Soup into a richer, more indulgent experience by adding 1 cup of heavy cream during the last 30 minutes of cooking. Increase the Parmesan to ¾ cup and add 4 oz of cream cheese for an ultra-silky texture that’s perfect for the coldest winter nights.
2. Veggie-Loaded Version
Boost the nutritional value of your Slow Cooker Chicken Parm Soup by adding 2 cups of chopped spinach, 1 diced red bell pepper, and 1 cup of sliced mushrooms during the last hour of cooking.

3. Spicy Arrabbiata Style

4. Mediterranean Twist
Add a Mediterranean flair to your Slow Cooker Chicken Parm Soup by incorporating 1 cup of kalamata olives, 2 tablespoons of capers, and 1 teaspoon of anchovy paste during the last hour of cooking. Finish with fresh oregano instead of basil and a sprinkle of lemon zest to brighten the flavors.
5. Fall Harvest Version
Create a seasonal adaptation of Slow Cooker Chicken Parm Soup by adding 1 cup of cubed butternut squash and 2 diced apples during the initial cooking phase. The squash adds hearty texture while the apples melt into the broth, adding a subtle sweetness that complements the tomato base beautifully.

Frequently Asked Questions About Slow Cooker Chicken Parm Soup
Can I make Slow Cooker Chicken Parm Soup ahead of time?
Absolutely! This soup actually improves with time as the flavors meld together. Make it up to 2 days ahead, but store the soup base separate from the cheese toppings and breadcrumbs. Reheat the base thoroughly, then add fresh toppings just before serving for the best texture contrast in your Slow Cooker Chicken Parm Soup.
How should I store leftover Slow Cooker Chicken Parm Soup?
Let the soup cool completely, then transfer to airtight containers and refrigerate for up to 4 days. For longer storage, freeze portions in freezer-safe containers for up to 3 months. The soup base freezes beautifully, but add fresh cheese and breadcrumb toppings after reheating for the best texture and flavor.
Can I use frozen chicken for this Slow Cooker Chicken Parm Soup?
While fresh chicken gives the best flavor and texture, you can use frozen chicken breasts in a pinch. Skip the searing step and add an additional hour to your cooking time on low. Be sure to check that the chicken reaches an internal temperature of 165°F before shredding.
How can I thicken my Slow Cooker Chicken Parm Soup if it’s too thin?
If your soup needs thickening, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water to create a slurry. Add this to the slow cooker during the last 30 minutes of cooking with the heat set to high. Alternatively, puree 1 cup of the soup (without chicken pieces) and return it to the pot for a naturally thickened base without additional ingredients.
Can I make this Slow Cooker Chicken Parm Soup in an Instant Pot?
Yes! For an Instant Pot version, use the sauté function to sear the chicken and cook the aromatics. Add all remaining soup ingredients, seal, and cook on high pressure for 15 minutes with a 10-minute natural release. Shred the chicken, then use the sauté function again while adding the cheese to melt it properly. Top with breadcrumbs and basil just before serving.
Is there a dairy-free version of Slow Cooker Chicken Parm Soup?
Definitely! Replace the mozzarella with your favorite plant-based mozzarella-style shreds (cashew-based versions melt particularly well). Substitute nutritional yeast for the Parmesan to maintain that umami flavor. Add 1 tablespoon of white miso paste to the broth for added depth that you might miss without the traditional cheese.
