Prep the chicken: Pat chicken breasts dry and season lightly with salt and pepper. This helps them hold onto flavor and prevents bland spots.
Mix the sauce: In a bowl, combine buffalo sauce, melted butter, ranch seasoning (or garlic/onion powder), smoked paprika, and brown sugar or honey if using.
Stir until smooth. Add a splash of chicken broth if you want extra sauciness.
Load the crockpot: Place the chicken in the slow cooker. Pour the sauce over the top, turning the breasts to coat.
Add the vinegar or lemon juice for brightness.
Cook low and slow: Cover and cook on Low for 3–4 hours or on High for 1.5–2.5 hours, until the chicken is cooked through and easily shreds. Internal temperature should reach 165°F.
Shred and sauce: Transfer chicken to a cutting board and shred with two forks. Return it to the crockpot and toss in the warm sauce so it soaks up every drop.
Adjust and serve: Taste and add a pinch of salt, extra buffalo sauce for more heat, or a little butter for richness.
Serve on buns, in tacos, over rice or cauliflower rice, or on top of a salad.
Garnish: Finish with crumbled blue cheese or a drizzle of ranch, plus sliced green onions and chopped celery for crunch.
