Ingredients

Scale
  • 2 pounds boneless, skinless chicken breasts (or thighs)
  • 3 large yellow onions, thinly sliced (about 4 cups)
  • 3 cloves garlic, minced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 teaspoon dried thyme (or 1 tablespoon fresh thyme)
  • 1/2 teaspoon smoked paprika (optional)
  • 1 cup low-sodium beef broth
  • 1 tablespoon Worcestershire sauce
  • 12 slider buns (such as Hawaiian rolls)
  • 8 ounces Swiss cheese, sliced (or Gruyère, provolone, or mozzarella)
  • 2 tablespoons unsalted butter, melted (for brushing buns)
  • 1 teaspoon garlic powder (optional, for melted butter)
  • Fresh chopped parsley or chives, for garnish (optional)

Instructions

  1. Peel and thinly slice the onions.
  2. Add onions to the bottom of the crockpot. Sprinkle with minced garlic, 2 tablespoons butter (cut in pieces), and olive oil. Toss gently to coat.
  3. Lay chicken breasts (or thighs) on top of the onions. Sprinkle with salt, pepper, thyme, and smoked paprika if using.
  4. Pour in beef broth and Worcestershire sauce.
  5. Cover and cook on LOW for 5-6 hours or HIGH for 3-4 hours, until chicken shreds easily and onions are golden and jammy.
  6. Transfer chicken to a plate and shred with two forks. Return shredded chicken to the crockpot and stir to combine with onions. Let sit in juices for at least 10 minutes.
  7. Slice slider buns in half. Lay bottom halves in a baking dish or on a lined baking sheet. Preheat broiler to high (or oven to 400°F).
  8. Spoon chicken and onion mixture onto each bun base using a slotted spoon. Top evenly with sliced cheese.
  9. Broil (or bake) sliders for 2-3 minutes, until cheese is bubbly and melted. Watch closely.
  10. Place bun tops on, brush with melted butter mixed with garlic powder if using. Broil for another 1-2 minutes until golden.
  11. Sprinkle with chopped parsley or chives if desired. Let cool for a minute, then pull apart and serve warm.

Notes

For gluten-free sliders, use gluten-free buns. For dairy-free, use vegan cheese or omit cheese and use olive oil instead of butter. Always use a slotted spoon to assemble to avoid soggy buns. Broil cheese and bun tops for best texture. Add mushrooms for extra flavor or swap in chicken thighs for juicier meat. The chicken mixture freezes well for up to 2 months.
