Cook Chicken Breasts: Bring a large pot of water to a boil. Add 4 boneless, skinless chicken breasts and reduce temp to bring water to a simmer. Let simmer 15-20 minutes. Carefully remove chicken and ensure center of thickest part of chicken has reached 165℉.
Shred + Sauce: Place chicken on a plate and shred with two forks. Move shredded chicken to a bowl with 1 - 1 ½ cups buffalo sauce; stir to combine.
Build Sandwiches: Open a hamburger bun, lay down some lettuce, add your buffalo chicken, blue cheese, and green onions on top, drizzle on some ranch and put the other half of your bun on top! Super easy and so good!
Notes
Buffalo Sauce: feel free to use whatever buffalo sauce you prefer, but we do have an easy homemade buffalo sauce, if you want it!
Buns: use whatever hamburger buns you prefer: gluten-free, paleo, whole wheat, etc.
Cook Time Listed: I used the stove-top method for the listed cook time – of course if you opt for the slow cooker or instant pot it will take longer than that.
Slow Cooker: Put 4 chicken breasts in a slow cooker with 1 cup buffalo sauce. Cover and cook on high for 3-4 hours or low 6-8 hours. Shred chicken and return to the pot with about 1/2 cup more buffalo sauce (add more or less, as desired).
Instant Pot: Put 1 cup chicken broth (or water) in the Instant Pot (no trivet needed) and then the chicken breasts. Cover, seal, and cook on high pressure for 8-10 minutes. Let it naturally release. Remove chicken, pour out any excess liquid, shred the meat and return to the pot with a 1/2 cup or more of buffalo sauce.
