Prep the slow cooker: Add the chicken breasts, buffalo sauce, chicken broth, butter, garlic powder, onion powder, smoked paprika, and a pinch of salt and pepper to the crockpot. Stir or flip the chicken to coat.
Cook low and slow: Cover and cook on Low for 4–5 hours or High for 2.5–3 hours, until the chicken is tender and easily shreds with two forks.
Shred the chicken: Transfer the chicken to a cutting board and shred with two forks.
Return it to the crockpot and toss with the sauce. Taste and adjust seasoning. If you want more heat, stir in extra buffalo sauce now.
Thicken if needed: If the mixture seems too saucy, let it cook uncovered on High for 10–15 minutes, stirring once or twice.
It should be juicy but not soupy.
Make the drizzle: In a small bowl, mix Greek yogurt with ranch or blue cheese dressing. Thin with a splash of water if you prefer a lighter drizzle.
Prep the lettuce: Separate the lettuce leaves carefully. Rinse and pat dry so they’re crisp and sturdy.
Assemble the wraps: Spoon buffalo chicken into lettuce leaves.
Top with celery, carrots, avocado, blue cheese or cheddar, and chives. Add a squeeze of lemon or lime if you like brightness.
Finish with drizzle: Add the yogurt-ranch or blue cheese drizzle. Serve extra buffalo sauce on the side for heat lovers.
