Main Ingredients
  • 1.5 lbs 4 boneless, skinless chicken breasts
  • 1 large yellow onion, thinly sliced Adds sweetness and depth.
  • 1 large red bell pepper, sliced Provides color and crunch.
  • 4 pieces hoagie rolls Or sturdy sub buns.
  • 8 oz provolone cheese, sliced For melting over the chicken.
Sauce and Seasonings
  • 1 cup low-sodium chicken broth Forms the flavorful base.
  • 2 tbsp Worcestershire sauce Adds umami flavor.
  • 1 tbsp Dijon mustard Gives a hint of tanginess.
  • 2 cloves garlic, minced For aromatic goodness.
  • 1 tbsp olive oil Ensures the garlic and veggies cook beautifully.
  • 1/2 tsp smoked paprika Adds warmth.
  • 1/2 tsp onion powder Amplifies the onion flavor.
  • to taste Salt and freshly ground black pepper
  • 1/4 tsp red pepper flakes (optional) For those who enjoy a bit of heat.

Method
 

Preparation
  1. Start by patting the chicken breasts dry and seasoning both sides generously with salt, pepper, smoked paprika, and onion powder.
  2. Thinly slice the onion and red bell pepper. Mince the garlic and combine it with olive oil for added richness.
  3. Optional: Heat a skillet over medium-high heat and sear the seasoned chicken for about 2-3 minutes per side until lightly browned.
Slow Cooking
  1. Place the seared chicken into the slow cooker. Layer the onions, bell peppers, and garlic-oil mixture over the chicken.
  2. Pour in the chicken broth, Worcestershire sauce, and Dijon mustard. Add red pepper flakes if desired.
  3. Cover your slow cooker and cook on LOW for 4-5 hours or HIGH for 2-3 hours until the chicken is fork-tender.
  4. Once done, shred the chicken directly in the slow cooker and let it simmer uncovered on the 'keep warm' setting for 10-15 minutes.
Assembly
  1. Slice your hoagie rolls and generously fill them with the chicken mixture.
  2. Top with slices of provolone cheese, allowing the heat from the chicken to melt it.
  3. Serve your sandwiches hot, preferably with extra sauce on the side.

Notes

Consider adding sautéed mushrooms or jalapeños for extra crunch. You can prepare everything the night before by assembling in the slow cooker and refrigerating overnight. If in a rush, use pre-cooked rotisserie chicken for a quick meal.
