01 - Place chicken breasts in a medium saucepan or skillet with chicken broth, smoked paprika, garlic powder, onion powder, salt, and pepper. Bring to a simmer over medium heat, cover, and cook for 15-18 minutes until the chicken is cooked through and tender.
02 - Remove chicken from the pot and shred with two forks. Discard any excess liquid.
03 - In the same pan, combine barbecue sauce, Worcestershire sauce, hot sauce (if using), and brown sugar. Add shredded chicken back to the pan and stir to coat well. Simmer over low heat for 5 minutes until heated through.
04 - Preheat oven to 350°F. Slice slider buns in half and arrange bottoms on a baking sheet.
05 - Spoon generous portions of the sauced chicken onto each bun base. Sprinkle with shredded cheddar cheese and crispy fried onions.
06 - Place the bun tops over the sliders. Brush tops with melted butter.
07 - Bake sliders for 8-10 minutes until the cheese is melted and buns are slightly toasted.
08 - Garnish with chopped parsley if desired. Serve hot.
