- 1 teaspoon Italian seasoning: A fragrant herb blend that enhances the Mediterranean vibe.
- 1/2 teaspoon onion powder: Subtle sweetness and depth without overpowering.
- 1/2 teaspoon salt: Balances the flavors perfectly.
- 1/4 teaspoon black pepper: Adds mild heat and earthiness.
- 1/4 teaspoon red pepper flakes (optional): For anyone who likes a gentle kick of spice.
- 6 sandwich rolls or brioche buns: Soft and sturdy bread to hold all that juicy goodness.

How to Make Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe
Step 1: Prepare the Chicken and Sauce
Start by placing the chicken breasts into your slow cooker, creating the perfect canvas for the flavors to meld together. In a small bowl, whisk the melted butter with Parmesan cheese, minced garlic, Italian seasoning, onion powder, salt, pepper, and optional red pepper flakes. This vibrant mixture will infuse the chicken with a rich, tangy, and slightly spicy backdrop.
Step 2: Slow Cook to Tender Perfection
Pour the garlic Parmesan sauce over the chicken, ensuring every piece is covered in that luscious blend. Cover the slow cooker and set it to low for 6 to 7 hours or high for 3 to 4 hours. The magic happens as the low and slow heat breaks down the chicken fibers, making it unbelievably tender and easy to shred. The aroma alone will have your kitchen smelling heavenly.
Step 3: Shred and Coat the Chicken
Once the chicken is cooked through and tender, shred it directly in the slow cooker using two forks. Toss the shredded chicken in the butter and cheese sauce left behind, making sure every bite is coated with that creamy, garlicky goodness that defines this recipe.
Step 4: Assemble the Sandwiches
Toast your sandwich rolls or brioche buns if you prefer a little extra texture and crunch. Pile the shredded chicken generously onto each bun and sprinkle with shredded mozzarella cheese. Let the residual heat melt the cheese slightly, creating that irresistible gooey layer. Feel free to place the assembled sandwiches under a broiler for 2 to 3 minutes if you crave a golden, bubbly cheese topping.
How to Serve Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe

Garnishes
A sprinkle of fresh chopped parsley on top is a simple way to lift the entire dish with a burst of color and fresh, herbal brightness. The parsley also adds a subtle textural contrast that complements the creamy chicken perfectly.
Side Dishes
These sandwiches pair wonderfully with classic sides like crisp green salads, roasted vegetables, or even a light coleslaw to add some crunch. For those looking to keep things comforting, crispy oven fries or garlic Parmesan pasta work beautifully alongside the rich chicken sandwiches.
Creative Ways to Present
Serve the shredded chicken in mini slider buns for a crowd-pleasing appetizer or party snack. You can also turn this dish into an open-faced sandwich served with a drizzle of extra sauce and a side of pickled vegetables. The versatility of this Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe means you can adapt it to suit casual family dinners or festive gatherings alike.
Make Ahead and Storage
Storing Leftovers
Any leftover shredded chicken can be stored in an airtight container in the refrigerator for up to 3 days. Keeping the chicken separate from the buns prevents the bread from becoming soggy, ensuring your sandwiches stay fresh when reheated.
Freezing
You can freeze the shredded Parmesan garlic chicken by placing it in a freezer-safe container or bag. It will keep well for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the fridge for best results before reheating.
Reheating
Reheat leftovers gently in a skillet over low heat or in the microwave, adding a splash of water or extra butter if the mixture feels dry. Loading it back onto fresh toasted buns and melting mozzarella cheese again will revive that freshly made taste and texture.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs tend to be more tender and juicy, so they work wonderfully in this recipe. The cooking time remains about the same, and you’ll enjoy even richer flavor and moistness in your sandwiches.
What if I don’t have a slow cooker?
If you don’t own a slow cooker, you can simmer the chicken breasts and sauce in a covered pot on low heat for about 2 hours, or bake them in a covered dish at 325°F for about 1.5 to 2 hours. Just check regularly to ensure the chicken stays tender and moist.
Can I make this recipe gluten-free?
Yes! Simply swap out the sandwich rolls for gluten-free buns or rolls. The rest of the ingredients are naturally gluten-free, so you won’t miss any flavor or texture.
Is there a vegetarian version of this sandwich?
While this recipe centers on chicken, you could try substituting pulled jackfruit or large grilled portobello mushrooms with the Parmesan garlic sauce for a vegetarian twist. It won’t be the same, but it will still deliver a savory, satisfying sandwich experience.
How spicy does the red pepper flakes make the dish?
The red pepper flakes add a mild heat that gently lingers on the palate without overwhelming the rich Parmesan garlic flavors. You can easily leave them out if you prefer a completely mild sandwich, or add more if you like extra spice.
Final Thoughts
There’s something truly magical about the ease and flavor that comes together in this Slow Cooker Parmesan Garlic Chicken Sandwiches Recipe. It perfectly balances tender, juicy chicken, rich garlic butter, and melted cheese to create an utterly satisfying meal that’s forgiving for busy weeknights or casual entertaining.
