- Grated Parmesan Cheese (1/2 cup): Salty, nutty, and rich, Parmesan adds creaminess and a subtle kick to the filling.
- Italian Seasoning (1 tsp): Just a sprinkle gives your chicken a classic herbaceous backdrop.
- Mayonnaise (1/3 cup): It might sound unusual, but mayo creates a luxuriously silky sauce and helps everything stay moist.
- Lemon Juice (1 tbsp): Brightens things up, adding a little zing to balance the richness.
- Salt (1 tsp): Essential for bringing out all those layers of flavor.

- Sandwich Rolls (4 to 6): Soft, sturdy, or your personal favorite—these cradle all that chicken goodness.
- Olive Oil (1 tbsp): Brushed on rolls for toasting, adding a lovely golden edge and subtle flavor.
- Shredded Mozzarella Cheese (optional, 1/2 cup): Melts right in for extra gooey deliciousness (if you love cheese, definitely add it).

How to Make Slow Cooker Parmesan Garlic Chicken Sandwiches
Step 1: Prep and Load the Slow Cooker
First things first: gather your chicken, garlic, Parmesan, Italian seasoning, mayo, lemon juice, salt, and pepper. Pop everything right into the slow cooker and give it a good stir to make sure the chicken is evenly coated. It’s a breeze, and this simple step is where all the flavor-building begins for your Slow Cooker Parmesan Garlic Chicken Sandwiches.
Step 2: Let It Cook
Set your slow cooker to low for 4 to 5 hours, or crank it up to high for 2 to 3 hours if time’s not on your side. Walk away, binge your favorite show, or just enjoy having dinner handle itself—the slow cooker will do the work, turning the chicken succulent and pull-apart tender.
Step 3: Shred That Chicken
Once the chicken’s cooked through and practically falling apart, carefully remove it from the slow cooker. Using two forks, shred the meat right on a plate or a cutting board. This makes every bite perfectly textured and ready to soak up the dreamy sauce waiting in the slow cooker.
Step 4: Saucy Reunion
Slide the shredded chicken back into the slow cooker and stir everything together. This is where the magic happens: the chicken gets fully saturated in that Parmesan garlic sauce. Don’t be shy about giving it a thorough mix!
Step 5: Toast the Rolls
Brush your sandwich rolls with olive oil and toast them just until golden. It only takes a couple of minutes, but it makes all the difference—crisp outsides, pillowy insides, and a bit of extra olive oil flavor.
Step 6: Assemble and Garnish
Pile the saucy Parmesan garlic chicken high onto each roll, sprinkle on mozzarella if you like things cheesy, and crown with a shower of fresh basil or parsley. Serve up your Slow Cooker Parmesan Garlic Chicken Sandwiches warm, melty, and utterly irresistible.
How to Serve Slow Cooker Parmesan Garlic Chicken Sandwiches

Garnishes
Sprinkle your sandwiches with a handful of fresh basil or parsley just before serving. Not only does the vibrant color make your Slow Cooker Parmesan Garlic Chicken Sandwiches extra inviting, but those fresh herbs also lift the whole flavor profile with a rush of brightness.
Side Dishes
These sandwiches love some company! Try serving them with a crisp green salad, baked sweet potato fries, or even a simple bowl of tomato soup. For something heartier, a side of roasted veggies or garlic Parmesan potato wedges would be divine.
Creative Ways to Present
Go beyond the ordinary roll! You can spoon the chicken over ciabatta, stuff it into mini sliders for parties, or even use toasted baguette for a more rustic twist. For a low-carb version, try piling the chicken into lettuce cups topped with extra Parmesan and herbs.
Make Ahead and Storage
Storing Leftovers
Leftover chicken can be cooled and tucked into an airtight container, then stored in the fridge for up to three days. This makes it perfect for quick lunches or dinner round two—the flavors only deepen as they rest!
Freezing
Looking to meal prep? Portion the cooled shredded chicken (without garnishes or bread) into freezer bags or containers and freeze for up to three months. Thaw overnight in the refrigerator before reheating, and you’ll have a dinner shortcut ready to go.
Reheating
To bring leftovers back to life, reheat the chicken gently in a saucepan or microwave, adding a splash of water or chicken broth if it seems dry. Pile onto fresh rolls and warm in a low oven if you want that right-out-of-the-slow-cooker texture!
FAQs
Can I use frozen chicken breasts for this recipe?
It’s best to use thawed chicken breasts for food safety, but you can thaw your chicken overnight in the fridge first. Using frozen chicken directly in the slow cooker isn’t recommended.
Is there a way to make these sandwiches gluten-free?
Absolutely! Just substitute your favorite gluten-free rolls or bread, and you’re all set for deliciously gluten-free Slow Cooker Parmesan Garlic Chicken Sandwiches.
What other cheeses work well in place of mozzarella?
Try provolone, shredded cheddar, or even a little smoked gouda. Each adds a special twist, so experiment and find your favorite melty pairing!
How spicy can I make this?
Mix in a pinch—or a generous shake—of red pepper flakes with the sauce for a spicy kick. If you like things even hotter, chopped pickled jalapeños make a fun topping.
Can I double the recipe for a crowd?
Yes! Simply double all the ingredients and use a larger slow cooker. The cooking time may increase by about an hour; just check that all the chicken is cooked through and easily shreds.
