Recipe Details

• Flavor Profile: A robust and savory tomato broth infused with garlic, Italian herbs, and the salty, nutty richness of Parmesan cheese.
• Textures: Thick and satisfying with tender shredded chicken, firm pasta, and a stretchy, melty cheese topping.
• Total Time: 7 1/2 hours on low or 3 1/2 hours on high, plus about 15 minutes of final assembly.
• Difficulty Level: Easy – This is a simple “set it and forget it” slow cooker recipe that requires only basic pasta boiling at the end.

What You’ll Need

To create this flavorful soup, you will need a base of chicken stock, crushed tomatoes, and tomato paste. The aromatics include fresh garlic, green bell pepper, and white onion. For the heart of the soup, you will use boneless skinless chicken breast and penne pasta, finishing it all off with a trio of dairy: Parmesan, butter, and plenty of shredded mozzarella.

Ingredient Notes

• Garlic cloves – Freshly minced garlic provides the essential aromatic punch that defines Italian-style cooking.
• Green bell pepper and white onion – These vegetables are finely chopped to melt into the broth, adding subtle sweetness and depth.
• Crushed tomatoes – These provide the thick, saucy texture that makes the broth feel like a traditional marinara.
• Chicken breast – Raw chicken breast is slow-cooked directly in the broth, which keeps it incredibly moist and easy to shred.
• Chicken stock – This acts as the liquid base; keep a little extra on hand if you prefer a thinner soup consistency.
• Tomato paste – A small amount adds a concentrated tomato flavor and helps thicken the soup.
• Italian seasoning – A blend of herbs like oregano, basil, and rosemary that gives the soup its classic profile.
• Red pepper flakes – Adds just a hint of warmth without making the soup overly spicy.
• Penne pasta – A sturdy pasta shape that holds up well against the thick tomato broth and shredded chicken.
• Parmesan cheese – Grated Parmesan is stirred directly into the soup to create a salty, savory, and silky finish.
• Mozzarella cheese – Shredded mozzarella is used as a garnish to create that iconic melty cheese topping.

Add-ins and Substitutions

• Vegetable Boost – You can stir in two cups of fresh baby spinach at the very end until it wilts for extra nutrients.
• Pasta Shapes – While penne is traditional, rotini or bow-tie pasta also work well for catching the bits of chicken and cheese.
• Heat Level – If you prefer a completely mild soup, feel free to omit the red pepper flakes.
• Toppings – For a bit of crunch, serve the soup with a handful of seasoned garlic croutons on top.

How to Make Chicken Parmesan Soup

1. Combine in the slow cooker: In a 5-quart or larger slow cooker, stir together the minced garlic, chopped green bell pepper, white onion, crushed tomatoes, raw chicken breast, chicken stock, tomato paste, Italian seasoning, salt, black pepper, and red pepper flakes.
2. Slow cook: Cover the pot and cook on the low setting for 7 1/2 hours or on the high setting for 3 1/2 hours.
3. Prepare the pasta: When the slow cooker time is up, set the unit to the warm setting. Heat a medium pot of salted water to boiling on the stovetop. Cook the penne pasta according to the package instructions until it is just firm and tender, then drain it well.
4. Shred the chicken: While the pasta cooks, transfer the cooked chicken breast to a cutting board. Use two forks to coarsely shred the meat.
5. Final assembly: Add the grated Parmesan, optional butter, cooked pasta, and shredded chicken back into the slow cooker. Stir everything until it is well combined and the butter has melted.
6. Garnish and serve: Ladle the soup into bowls and serve immediately, topped with plenty of shredded mozzarella cheese and fresh chopped basil.

Pro Tip: Boiling the pasta separately on the stove ensures that the noodles stay perfectly firm and do not soak up too much of the broth or become mushy, which can sometimes happen when cooking pasta directly in a slow cooker.

Recipe Tips

• Consistent Chopping – Ensure the onion and bell pepper are finely chopped so they integrate smoothly into the broth during the long cook time.
• Shredding Secret – For the best texture, shred the chicken while it is still hot. It will pull apart much more easily and absorb the flavors of the broth instantly.
• Adjusting Consistency – If the soup becomes too thick after adding the pasta, simply stir in an extra 1/2 cup of warm chicken stock until you reach your desired consistency.
• Butter Addition – While optional, adding those 2 tablespoons of butter at the end gives the broth a professional, glossy finish and a richer mouthfeel.

FAQs

Can I use chicken thighs instead of breasts? Yes, boneless skinless chicken thighs can be used. They are very forgiving in the slow cooker and will remain quite tender, though the flavor will be slightly richer.

How do I prevent the cheese from clumping? Stirring the grated Parmesan into the hot broth while the slow cooker is on the warm setting helps it melt evenly. For the mozzarella topping, sprinkle it on just before serving so it melts perfectly over the heat of the bowl.

Can I cook the pasta in the slow cooker? To maintain the best texture for this specific recipe, it is recommended to cook the pasta separately as directed. This prevents the pasta from becoming overly soft during the long simmering process.

Serving Suggestions

• Garlic Bread – Serve with warm, buttery garlic bread or toasted ciabatta to dip into the tomato broth.
• Caesar Salad – A crisp romaine salad with a creamy Caesar dressing provides a refreshing contrast to the warm, cheesy soup.
• Roasted Broccoli – A side of lemon-roasted broccoli adds a nice bit of brightness and crunch to the meal.

Make This Recipe in Advance

You can chop the peppers, onions, and garlic up to two days in advance and keep them in the refrigerator until you are ready to start the slow cooker.

Storage: Store any leftover soup in an airtight container in the refrigerator for up to 3 to 4 days.

Reheating: When reheating, you may need to add a splash of broth as the pasta will continue to absorb liquid while it sits. Heat gently on the stovetop over medium-low heat.

Freezing: It is best to freeze the soup base (the broth and chicken) without the pasta. When you are ready to serve, thaw the soup, bring it to a simmer, and add freshly cooked pasta for the best results.

Notes

Storage and Reheating: Store leftovers in an airtight container in the refrigerator for 3-4 days. When reheating on the stovetop, add a splash of chicken stock to loosen the consistency, as the pasta will absorb liquid while sitting.

Pro Tip for Texture: Boiling the pasta separately on the stove is the secret to a professional-quality soup. It prevents the noodles from becoming mushy or starchy, ensuring they maintain a perfect al dente bite in the rich broth.

Variation: For a Vegetable Boost, stir in 2 cups of fresh baby spinach at the very end of the assembly process. The residual heat will wilt the spinach perfectly without overcooking it.
