Ingredients You’ll Need

The beauty of this Slow Cooker Chicken Parmesan Soup Recipe is how these simple, fresh ingredients team up to create a deeply satisfying dish — no fancy extras required. When shopping, look for ripe canned tomatoes and good-quality chicken stock to layer in those rich flavors.

• Garlic cloves: Fresh and minced to give the soup that signature aromatic punch.
• Green bell pepper: Finely chopped for subtle sweetness and texture without overpowering.
• White onion: Adds depth and balances the acidity from the tomatoes.
• Crushed tomatoes (canned): This is the heart of your broth, so pick a quality brand for a better flavor base.
• Boneless skinless chicken breast: Tender protein that shreds beautifully after slow cooking.
• Chicken stock: Use a good homemade or store-bought one for richness.
• Tomato paste: Concentrates the tomato flavor for that bold, saucy note.
• Italian seasoning: A blend of herbs that makes the flavor unmistakably Italian.
• Kosher salt: Essential for seasoning and bringing out all the other flavors.
• Ground black pepper: Adds a gentle kick and warmth.
• Red pepper flakes: Just enough heat to keep it interesting without overwhelming.
• Uncooked dry penne pasta: Cooked separately and stirred in for perfect al dente texture.
• Parmesan cheese: Adds salty umami goodness that’s the soul of Chicken Parmesan.
• Unsalted butter (optional): For extra velvet richness—totally worth it if you’ve got it.
• Shredded mozzarella cheese: Melted over the top, this makes every spoonful a bit indulgent.
• Fresh basil: Bright, fresh, and just the right herbal finish.

Variations

I love showing you how you can make this Slow Cooker Chicken Parmesan Soup Recipe your own — it’s so easy to swap or add ingredients to suit your mood or pantry. Don’t hesitate to play around with it! Here are some ways I’ve customized it over the years.

• Make it Spicy: I sometimes bump up the red pepper flakes or add a diced jalapeño for a serious kick that my spice-loving family begs for.
• Vegetable Boost: Toss in some chopped zucchini or mushrooms during the slow cook for extra veggies and bulk.
• Gluten-Free Version: Swap the penne for gluten-free pasta or spiralized veggies like zucchini noodles just before serving.
• Cheese Variations: Try substituting Pecorino Romano for Parmesan or adding a little fontina for a richer melt.

How to Make Slow Cooker Chicken Parmesan Soup Recipe

Step 1: Load Your Slow Cooker with Flavor

Start by tossing the minced garlic, finely chopped green bell pepper, chopped white onion, crushed tomatoes, raw chicken breasts, chicken stock, tomato paste, Italian seasoning, kosher salt, ground black pepper, and red pepper flakes into your slow cooker. Give everything a gentle stir to distribute the flavors. This is where the magic begins—once covered, the slow cooker will gently meld all these layers of flavor while you relax or tackle your day. I like using a 5-quart or larger cooker to leave enough space for stirring later on.

Step 2: Slow Cook with Patience

Set your slow cooker on low for around 7 and a half hours or on high for 3 and a half hours. Either way, you’re aiming for the chicken to be perfectly tender and the flavors to fully develop. Be careful not to rush this part—slow and steady really pays off here. When done, switch your slow cooker to warm or keep it on low to keep things cozy while you prepare the pasta.

Step 3: Cook the Pasta Separately for Perfect Texture

One of the tricks I learned the hard way was to NOT cook the pasta directly in the slow cooker. Instead, bring a medium pot of salted water to a boil and cook your penne pasta al dente according to the package instructions. This helps avoid mushy pasta and keeps your soup’s consistency just right—especially if you want leftovers to reheat well.

Step 4: Shred the Chicken and Combine

Carefully transfer the cooked chicken breasts onto a cutting board and shred them coarsely using two forks. Then, add the shredded chicken, cooked pasta, grated Parmesan cheese, and optional butter to the slow cooker. Stir it all together until perfectly combined, creamy, and ready to serve.

Step 5: Serve with Melty Mozzarella and Fresh Basil

Spoon the soup into bowls and top with plenty of shredded mozzarella and fresh chopped basil. The mozzarella melts wonderfully into the warm soup, adding a luscious texture that reminds you why Chicken Parmesan is pure comfort food. Basil adds that fresh pop that cuts through the richness.

How to Serve Slow Cooker Chicken Parmesan Soup Recipe

Garnishes

When I serve this soup, I always pile on fresh shredded mozzarella and a generous sprinkle of chopped basil. Sometimes I drizzle a little extra virgin olive oil on top for a silky finish. A bit of freshly grated Parmesan right before digging in never hurts either—it’s the little details that make each bite sing.

Side Dishes

I love pairing this with warm garlic breadsticks or a simple green salad dressed lightly with balsamic vinegar. Sometimes a side of roasted veggies works beautifully too, especially when I want to keep the meal lighter but still satisfying.

Creative Ways to Present

For special occasions, I’ll ladle the soup into pretty crock bowls and serve with fresh basil sprigs and mozzarella balls on skewers as an elegant garnish. It’s a fun twist that impresses guests yet still feels homey—and the aroma fills the whole room with cozy vibes.

Make Ahead and Storage

Storing Leftovers

Once fully cooled, transfer your leftover soup to airtight containers and pop them in the fridge. I’ve found it keeps beautifully for up to 3 days. Make sure to store the pasta separately if you want to avoid it soaking up too much broth and getting mushy overnight.

Freezing

I usually freeze this soup without the pasta because it freezes and reheats better that way. Just freeze the soup base and shredded chicken in a freezer-safe container or zip-top bag for up to 3 months. When ready, thaw in the fridge overnight and add freshly cooked pasta when reheating.

Reheating

Reheat your leftovers gently on the stovetop over medium heat, stirring often to avoid sticking. Add cooked pasta fresh or reheat stored pasta separately and combine just before serving. This keeps everything tasting fresh and prevents the pasta from getting gummy or mushy.
