Ingredients You’ll Need

I love how the ingredients in this Slow Cooker Italian Chicken Sandwiches Recipe come together simply but pack a punch of flavor. As you shop, look for good-quality boneless, skinless chicken thighs because they stay juicy and tender through the slow cooking process. Also, grabbing a jar of mild giardiniera and pepperoncini will be key to that signature tang!

• Boneless skinless chicken thighs: They stay juicy and don’t dry out like breasts can during slow cooking.
• Kosher salt: Enhances the natural flavors of the chicken perfectly.
• Freshly ground black pepper: Adds a little bite and warmth.
• Extra-virgin olive oil: For browning the chicken and adding depth to the dish.
• Yellow onion: Adds sweetness and soaks up the delicious chicken fat as it cooks.
• Low-sodium chicken broth: Keeps the chicken moist and adds a savory base.
• Italian seasoning: A blend that brings all those classic Italian herbs in one pinch.
• Garlic powder: For a mellow garlic flavor that permeates the chicken.
• Onion powder: Boosts the onion flavor throughout the dish.
• Pepperoncini slices and their brine: The tangy, slightly spicy peppers are a must for authentic flavor.
• Chopped giardiniera (mild): This pickled vegetable mix adds a crunchy, tangy kick your taste buds will thank you for.
• Hoagie buns: Perfect soft and sturdy vessels for piling on that shredded chicken.
• Provolone cheese slices: Melts perfectly into the sandwich for a creamy touch.

Variations

I’m all about making recipes work for you, so I’ve played around with some variations of this Slow Cooker Italian Chicken Sandwiches Recipe to mix things up or alter it for different diets. Try one—or combine a few—to really make this dish your own.

• Use chicken breasts instead of thighs: I used to worry about dryness, but cooking on low for the full time with broth keeps them tender too.
• Spice it up: Add a pinch of red pepper flakes if you like a little heat; it wakes up the tangy flavors beautifully.
• Make it dairy-free: Skip the provolone or swap it with a plant-based cheese to keep it allergy-friendly without losing the sandwich vibes.
• Switch up the bun: Sometimes I go for ciabatta rolls or even a hearty sourdough for a different texture and flavor.

How to Make Slow Cooker Italian Chicken Sandwiches Recipe

Step 1: Brown the Chicken and Sauté the Onions for Extra Flavor

First things first, season both sides of your chicken thighs with kosher salt and freshly ground black pepper. Then heat the olive oil in a large skillet or Dutch oven over medium-high heat. When the oil’s shimmering, add the chicken without crowding the pan — let it sear undisturbed for about 4 to 5 minutes until golden and releasing easily from the pan. Nestle in your sliced onions between the thighs and let them soak up all that lovely chicken fat as you flip the chicken over to brown the other side, another 4 to 5 minutes. This step really amps up the flavor, but I’ve made this recipe without browning in a hurry, and it still comes out fabulous. Once browned, transfer the chicken and onions to your slow cooker.

Step 2: Add Seasonings, Broth, and Peppers

Sprinkle the Italian seasoning, garlic powder, and onion powder evenly over the chicken and onions in the slow cooker. Pour in the chicken broth to keep everything moist, then add your pepperoncini slices along with about a third of a cup of their tangy brine. Toss in the drained giardiniera — the mild kind works best here to give a little tang without overpowering the other flavors. Give everything a gentle stir with a wooden spoon to distribute the seasonings and peppers.

Step 3: Slow Cook Low and Slow (Or Faster on High)

Cover the slow cooker and set it on low for 6 to 8 hours, or if you’re short on time, use the high setting for 3 to 4 hours. The chicken will cook until it’s fall-apart tender and infused with all those lovely Italian and tangy flavors. Around the finishing time, use tongs or a slotted spoon to move the chicken to a baking sheet and shred it with two forks. Toss the shredded chicken back into the slow cooker juices, stir gently, and switch the slow cooker to warm to keep everything cozy while you prepare your buns.

Step 4: Toast and Assemble Your Sandwiches

Preheat your oven to 375°F. Slice your hoagie buns and lay them open on a baking sheet. Toast them in the oven for about 5 minutes until the edges just start to turn golden. Then, layer the bottom half of each bun with a slice of provolone cheese — it melts a little from the heat of the bun and the warm chicken, adding that creamy touch. Pile on your shredded Italian chicken mixture, and top with extra pepperoncini slices and giardiniera for crunch and tang. Close the sandwich and get ready for your first delicious bite!

How to Serve Slow Cooker Italian Chicken Sandwiches Recipe

Garnishes

I like topping these sandwiches with extra chopped giardiniera and pepperoncini slices for that fresh, tangy crunch with every bite. Sometimes I add a few fresh basil leaves or a drizzle of good olive oil if I’m feeling fancy. You’ll find that these toppings elevate the sandwiches from simple to spectacular.

Side Dishes

My go-to sides with these sandwiches are crispy oven-baked fries or a simple green salad dressed with a light vinaigrette to balance out the richness. On game day, serving alongside classic potato chips and pickles completes the ultimate crowd-pleasing spread.

Creative Ways to Present

For casual parties, I’ve turned this into a sandwich bar—letting guests add their own giardiniera, cheeses, and extra peppers. It’s such a fun way to get everyone involved. Or, for a sit-down dinner, slice the sandwiches in half and stack them on a rustic wooden board with fresh herbs scattered around for a cozy Italian vibe.

Make Ahead and Storage

Storing Leftovers

Leftover shredded chicken keeps beautifully in an airtight container in the fridge for up to 4 days. I like to separate the chicken from the buns to prevent sogginess. When you’re ready to eat, just reheat the chicken gently and toast fresh buns.

Freezing

I often freeze the shredded chicken mixture in portioned freezer-safe containers or bags. It freezes amazingly well and thaws in the fridge overnight. When you defrost, the flavors taste even better after resting.

Reheating

I reheat leftovers by warming the shredded chicken in a skillet over medium-low heat with a splash of chicken broth to keep it moist. Toast the buns fresh or warm them in the oven for a few minutes, then assemble and enjoy as if it were freshly made.
