Cook the chicken breasts. I like to place them on a parchment lined baking sheet (seasoned with salt and pepper) and bake in the oven at 350℉ for 20 minutes or until the internal temperature reads 165℉. Allow to cool.
Shred the chicken and set aside.
Mix the ranch dressing, buffalo sauce, cream cheese and add to the slow- cooker. Stir until smooth.
Cook on low for 2-3 hours.
Lastly, grate the cheeses and add them to the dip (20 minutes before serving), stirring until thoroughly combined. Once the cheese is all melted, it’s ready to serve. Garnish with green onions (optional).
