Instructions

Season the Chicken

Start by seasoning the chicken breasts evenly with salt, freshly ground black pepper, garlic powder, and Italian seasoning. This seasoning mix helps to build layers of flavor that penetrate the meat during cooking.

Add the Flavorings

Pour the chicken broth carefully around the edges of the slow cooker to avoid washing away the seasoning on top of the chicken. Then sprinkle the minced garlic and grated Parmesan cheese directly over the breasts. Finally, dot the butter pieces evenly on top to introduce a rich, creamy texture as they melt.

Slow Cook Low and Slow

Cover the slow cooker and cook the chicken on low heat for 6 to 7 hours, or on high for 3 to 4 hours. This gentle cooking breaks down the chicken fibers, making it incredibly tender and almost shreddable straight from the pot.

Shred and Coat

Use two forks to shred the chicken directly after removing it from the slow cooker. Return the shredded chicken back to the cooking juices and stir well to thoroughly coat every strand with the flavorful broth and melted cheese.

Build the Sandwiches

Fill sandwich rolls or buns generously with the shredded Parmesan garlic chicken. Customize with optional toppings like crisp lettuce, fresh tomato slices, pesto, or mayo to enhance the texture and flavor contrast.

Serve Warm

Serve these sandwiches fresh and warm, pairing them with classic sides like crunchy chips, a vibrant green salad, or tangy pickles for a well-rounded meal that satisfies every craving.

You Must Know

  • Save some of the cooking juices and drizzle over the shredded chicken for added moisture and flavor.
  • Feel free to add slices of provolone or extra Parmesan on the rolls to elevate the cheesiness.
  • Fresh herbs like basil or parsley make wonderful garnishes that add a burst of color and brightness.
  • You can prepare this dish earlier in the day using the slow cooker and assemble sandwiches right before serving.

Storage Tips

Store any leftover shredded chicken with its cooking juices in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or microwave to maintain moisture before assembling new sandwiches.

Serving Suggestions

These sandwiches pair beautifully with classic potato chips, a crisp garden salad, or pickled vegetables. For a heartier option, serve with a side of roasted vegetables or creamy coleslaw for contrast and extra nutrition.

Professional Tips

  • Use overlapping layers of seasoning for well-balanced flavor penetration into the chicken.
  • Shred the chicken immediately after cooking while it’s still warm to achieve the best texture.
  • Adjust the amount of garlic based on your preference, but the slow cooking intensifies its presence effectively.
  • Choose sturdy sandwich rolls that hold up to moist fillings without getting soggy quickly.

FAQs

What are good alternative toppings?

Try adding sautéed mushrooms, caramelized onions, or roasted peppers for different flavor profiles and textures.

Can I make this without a slow cooker?

You can cook the chicken in a covered baking dish in the oven at 325°F for about 1.5 to 2 hours, covered with foil and adding broth to keep moist.

Is this recipe gluten-free?

It is gluten-free as long as you choose gluten-free rolls or buns and confirm the seasoning ingredients are free from gluten additives.

How do I increase cheesiness?

Mix in shredded mozzarella or provolone into the shredded chicken after cooking, and melt slightly before assembling for gooey texture.
