Slow Cooker Chicken Parmesan Sandwiches are the answer for busy nights when you crave something comforting with minimal effort. Juicy shredded chicken gets coated in marinara, finished with plenty of cheese, then piled onto toasted buns for a warm and hearty meal. This is a set it and forget it recipe that never fails to make the whole house smell amazing.
The first time I made these sandwiches for a weekend lunch, we all ended up hovering over the slow cooker with our forks. Now anytime I want an easy comfort food dinner, this recipe makes an appearance.
Ingredients
- Boneless skinless chicken breast: This lean and hearty protein shreds perfectly after slow cooking. Choose breasts that are firm and pink with no discoloration for the best results
- Italian seasoning: Provides herby flavor with balance. Look for blends with lots of oregano and basil
- Kosher salt: Ensures the chicken is well seasoned. Make sure to sprinkle evenly
- Garlic powder: Delivers subtle depth. Always choose garlic powder over garlic salt for this
- Marinara sauce: Gives rich tomato flavor to the chicken. Go for a brand with minimal added sugar and real tomatoes
- Grated parmesan cheese: Brings salty and nutty notes. Freshly grated has more punch if you have it
- Hamburger buns: Serve as the perfect vessel for all the cheesy chicken. Try to grab whole wheat or sturdy bakery buns for best texture
- Mozzarella cheese: Melts into gooey goodness. Slice fresh or use pre sliced for even coverage
Step-by-Step Instructions
- Prepare the Seasoned Chicken:
- Pat the chicken breast dry with a paper towel if needed. Lay them flat in your slow cooker. Sprinkle over the Italian seasoning, kosher salt, and garlic powder, making sure every surface is coated
- Slow Cook with Sauce:
- Pour the marinara sauce over the chicken. Cover every chicken piece and let the sauce drip down so the bottom pieces get flavor too. Put the lid on and cook on low for eight hours or high for about four hours. Your chicken is ready when it shreds easily with a fork and is no longer pink inside
- Shred and Cheese:
- Once the chicken is cooked, remove it from the slow cooker and set on a sturdy cutting board. Use two forks to pull the chicken apart into shreds. Return all the shredded chicken to the slow cooker. Add the grated parmesan and stir until all the chicken is cheesy and juicy
- Broil the Sandwiches:
- Turn your broiler to high. Slice and toast the buns if you like crisp edges. Place the bottom halves of buns on a baking sheet lined with parchment or foil. Spoon the chicken mixture on each and cover with a slice of mozzarella cheese
- Melt and Serve:
- Slide the tray under the broiler for about two minutes. Just long enough for the cheese to bubble and melt. Watch closely so the buns do not burn. Top with the remaining buns. Serve them up while hot and gooey

Parmesan cheese is hands down the ingredient that takes this sandwich over the top I always use a little extra because its saltiness and nuttiness make the sauce so much richer My kids love grabbing a few crunchy bits off the baking sheet before we call everyone to the table
Storage Tips
Leftover sandwiches keep well in the fridge for up to three days Just store the chicken mixture and buns separately to avoid sogginess Pop the chicken in the microwave and toast the buns for that fresh made taste even later in the week
Ingredient Substitutions
You can easily swap rotisserie chicken for the slow cooker version if you need dinner on the table in under thirty minutes If you are out of mozzarella try provolone or even a mix of cheddar for a different cheesy pull Gluten free buns work great too if you need a celiac friendly option
Serving Suggestions
