- ½ teaspoon dried Italian seasoning: A fragrant blend of herbs to give a hint of Mediterranean flair.
- ¾ cup mayonnaise: Creates a smooth, creamy foundation for the sauce.

How to Make Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe
Step 1: Prepare the Chicken and Sauce
Place the chicken breasts or thighs evenly in the bottom of your slow cooker. This forms a perfect base that will soak up the delicious sauce that follows. In a separate bowl, combine Parmesan cheese, garlic powder, onion powder, black pepper, salt, and dried Italian seasoning for that well-rounded flavor profile. Mix in mayonnaise, sour cream, and chicken broth until the mixture is smooth and creamy, ensuring an even coating for the chicken.
Step 2: Pour the Sauce Over the Chicken
Pour the creamy Parmesan garlic mixture over the chicken in the slow cooker, spreading it out to cover every piece. This ensures that as the chicken cooks, it will absorb the tangy and savory flavors, making each bite bursting with flavor and juiciness.
Step 3: Slow Cook to Perfection
Cover the slow cooker and set it to cook on low for 6 to 7 hours or on high for 3 to 4 hours. This slow cooking process tenderizes the chicken beautifully, allowing it to shred easily. The extended cooking time also thickens the sauce, coating the chicken in a creamy, garlicky Parmesan hug that’s pure bliss.
Step 4: Shred and Stir
Once the chicken is cooked through and tender, shred it directly in the slow cooker using two forks. Stir the shredded chicken well so it fully combines with the creamy sauce, creating that perfect balance of texture and flavor for your sandwiches.
Step 5: Assemble the Sandwiches
Toast your sandwich rolls if desired to add a bit of crunch and warmth. Pile generous amounts of the creamy garlic Parmesan chicken onto each bun, top with slices of provolone or mozzarella cheese, and add your favorite extras like baby spinach, arugula, or roasted red peppers. Serve immediately while warm for the best experience.

Garnishes
Adding fresh baby spinach or peppery arugula gives a vibrant green crunch that brightens the creamy richness of the chicken. Roasted red peppers add a smoky-sweet depth and a pop of color that makes each bite more exciting. Don’t skip the melted provolone or mozzarella cheese—it’s the crowning jewel that transforms this sandwich into an irresistibly gooey delight.
Side Dishes
Pair your Slow Cooker Parmesan Garlic Chicken Sandwiches with crispy oven-baked fries, a fresh garden salad, or even a comforting bowl of tomato soup. These sides complement the creaminess of the chicken with crisp or tangy flavors, rounding out your meal for any occasion.
Creative Ways to Present

You can also turn the shredded chicken into a hot dip by layering it in a casserole dish topped with extra cheese and baking it until bubbly—perfect for sharing. These sandwiches are so versatile, the presentation is only limited by your imagination!
Make Ahead and Storage
Storing Leftovers
Leftover Slow Cooker Parmesan Garlic Chicken keeps wonderfully in an airtight container in the fridge for up to 3 to 4 days. Simply reheat it gently in a skillet or microwave and pile onto fresh buns for an easy next-day meal that tastes just as delicious.
Freezing
This recipe is freezer-friendly! After cooking and shredding the chicken, let it cool, then transfer to a freezer-safe container or bags. Freeze for up to 3 months. When you’re ready to enjoy, thaw in the fridge overnight and reheat thoroughly before assembling your sandwiches.
Reheating
Reheat your Slow Cooker Parmesan Garlic Chicken gently on the stovetop over low heat or in the microwave until warmed through. Add a splash of chicken broth if the sauce feels too thick after refrigeration to help restore its creamy consistency.
FAQs
Can I use chicken thighs instead of breasts for this Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe?
Absolutely! Chicken thighs are even more tender and flavorful when slow-cooked, so feel free to substitute them for a richer taste and juicier texture.
Is it possible to make this recipe dairy-free?
You can try substituting dairy ingredients with plant-based alternatives like vegan Parmesan, dairy-free mayo and sour cream. Keep in mind it might slightly change the flavor and creaminess, but the slow cooker method will still yield tender chicken.
How do I prevent the sandwich buns from getting soggy?
To avoid soggy buns, consider toasting them lightly before assembling the sandwiches. You can also serve the creamy chicken on the side as a dip for more crunch and texture contrast.
Can I double this Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe to feed a crowd?
Definitely! Simply double all the ingredients and use a slow cooker large enough to accommodate the extra volume. Cooking times may remain the same, but check for tenderness and adjust if necessary.
What cheese melts best on these chicken sandwiches?
Provolone and mozzarella are top choices as they melt smoothly without overpowering the other flavors. Feel free to experiment with mild cheddar or fontina for a twist on the classic.
