In a slow cooker, place the chicken thighs and cover them with half of the buffalo sauce. Cook on low for 4-5 hours or until the chicken is tender and easily shredded.
Once cooked, remove the chicken from the slow cooker, shred it with two forks and return it to the cooker. Add the softened cream cheese and remaining buffalo sauce. Stir until the cream cheese is fully incorporated and the chicken is coated in a creamy buffalo sauce.
Preheat the oven to 350°F (175°C). Arrange the slider buns on a baking sheet and toast them lightly in the oven for about 5 minutes.
On the bottom half of each toasted slider bun, add a leaf of lettuce, followed by a generous scoop of the buffalo chicken mixture. Sprinkle the shredded cheddar cheese and chopped green onions over the chicken.
Place the top half of the slider bun on each assembled slider. If desired, add optional toppings like sliced jalapeños or pickles before serving.
Notes
Serve with extra buffalo sauce and ranch dressing on the side for dipping.
