Ingredients You’ll Need

The beauty of this Slow Cooker Italian Chicken Sandwiches Recipe is in the simplicity of the ingredients coming together for maximum flavor. Using boneless chicken thighs ensures juicy meat that shreds easily, while pepperoncini and giardiniera bring that classic Italian zing.

• Boneless Skinless Chicken Thighs: I prefer thighs for their extra flavor and tenderness compared to breasts.
• Kosher Salt: Seasoning well upfront is key to drawing out flavor in slow cooker recipes.
• Freshly Ground Black Pepper: Adds a subtle spice that stands up perfectly to the tangy pepperoncini.
• Extra-Virgin Olive Oil: For that initial browning step, adding a little caramelized flavor.
• Yellow Onion (Sliced): Softens during cooking and adds a mild sweetness that balances the sour notes.
• Low-Sodium Chicken Broth: Keeps the meat moist and infuses savory goodness without overpowering.
• Italian Seasoning: A blend of herbs that makes this sandwich unmistakably Italian-inspired.
• Garlic Powder and Onion Powder: To boost the savory depth in the slow cooker sauce.
• Pepperoncini Slices and Brine: The real MVP here giving the perfect tang and mild spice.
• Giardiniera (Chopped & Drained): Mild is usually best—adds crunch and a peppery bite.
• Hoagie Buns: Soft buns that hold all the saucy, tender chicken without falling apart.
• Provolone Cheese Slices: Melts beautifully and rounds out the flavors with creamy richness.

Variations

I love how adaptable this Slow Cooker Italian Chicken Sandwiches Recipe is. Whether you’re catering to dietary needs or just feeling adventurous, there’s a tweak here for everyone. Don’t be afraid to make it your own!

• Gluten-Free: I’ve made this on gluten-free buns multiple times and honestly, no one ever notices the difference — still melty and delicious.
• Dairy-Free or Vegan Cheese: Try your favorite dairy-free cheese, or omit the cheese entirely for a lighter option; the chicken stays flavorful without it.
• Spicier Kick: Add sliced jalapeños or more pepperoncini brine if you enjoy heat — I did this once for a game day and it was a hit.
• Additional Veggies: Toss in sliced bell peppers or mushrooms in the slow cooker for a heartier filling that sneaks in some extra veggies.

How to Make Slow Cooker Italian Chicken Sandwiches Recipe

Step 1: Season and Brown the Chicken

First things first—season both sides of your chicken thighs generously with kosher salt and freshly ground black pepper. I like to give the chicken a quick sear in a hot skillet with olive oil until golden brown on each side, about 4-5 minutes per side. This step is optional, but I discovered it adds a delicious depth of flavor and a lovely color to the final dish. Don’t worry if you’re short on time; skipping browning still yields tender, tasty chicken in the slow cooker.

Step 2: Layer Onions and Transfer to Slow Cooker

Once the chicken is browned on one side, slip those sliced onions right between the thighs in the pan so they soak up all that chicken fat—it’s like flavor magic. After browning the second side, transfer both the chicken and onions to your slow cooker. This little step always makes me feel like I’m building flavor layers the right way.

Step 3: Add Seasonings, Broth, and Peppers

Now sprinkle the Italian seasoning, garlic powder, and onion powder over the chicken and onions. Pour in the chicken broth, pepperoncini slices, about a third cup of their brine, and the drained giardiniera. Give everything a gentle stir with a wooden spoon—careful not to break the chicken up just yet. Cover the slow cooker and let it work its magic on low for 6-8 hours (or on high for 3-4 hours). The slow cooking is what makes this sandwich so luscious and tender.

Step 4: Shred the Chicken

When time’s up, use tongs to transfer the chicken to a baking sheet and shred it with two forks. I find this easier when the meat’s still warm because it pulls apart effortlessly. Slide the shredded chicken back into the slow cooker with all those flavorful juices and give it a gentle stir to soak it all in. Switch your slow cooker to warm to keep everything perfect until you’re ready to assemble.

Step 5: Toast Buns and Assemble Sandwiches

Last step—preheat your oven to 375°F. Split the hoagie buns and place them cut side up on a baking sheet. Toast for about 5 minutes until edges turn slightly golden and the crust crisps up just a bit. Then, add a slice of provolone cheese to the bottom half of each bun; the cheese will melt perfectly against the warm shredded chicken piled on top. Finish with extra pepperoncini slices and a spoonful of giardiniera for that final punch of flavor and crunch. That’s it—pure sandwich bliss.

How to Serve Slow Cooker Italian Chicken Sandwiches Recipe

Garnishes

I’m all about a little extra crunch and tang on these sandwiches. I always pile on some chopped giardiniera and a few pepperoncini slices on top for that wonderful contrast of textures and a bit of heat. If you like, add fresh basil leaves or a drizzle of olive oil for a fresh twist that brightens the whole plate.

Side Dishes

We often pair these sandwiches with classic Italian side dishes like a simple arugula salad dressed with lemon and olive oil or some garlicky roasted potatoes. For a cozy night, creamy coleslaw or baked zucchini sticks also make fantastic accompaniments.

Creative Ways to Present

When hosting, I love serving mini versions of these sandwiches at my parties—just use slider buns, melt some provolone, and arrange them on a large platter with toothpicks. It’s an easy crowd-pleaser that looks gorgeous and invites people to dig in. For a fancier dinner, pair with a charcuterie board for a casual Italian-inspired spread.

Make Ahead and Storage

Storing Leftovers

Leftover shredded chicken keeps beautifully in an airtight container in the fridge for up to 4 days. I store the chicken with some of the cooking juices to keep it moist—trust me, this saves the meat from drying out when reheating.

Freezing

This sandwich filling freezes wonderfully. I portion out the shredded chicken with broth into freezer-safe bags or containers, squeezing out excess air before sealing. When I want a quick meal, I just thaw overnight in the fridge and reheat gently.

Reheating

I reheat leftover chicken slowly in a saucepan over low heat, adding a splash of chicken broth to keep it juicy. Microwaving works too, but be sure to cover to trap steam and avoid drying out. Toast fresh buns and add cheese to keep that melty magic alive.
