Add chicken wings to your Crock-Pot.
Mix together buffalo sauce and ranch seasoning in a bowl until combined.
Pour mixture over chicken wings and toss to coat.
Cover and cook on low for 5-6 hours.
Heat broiler. Line two baking sheets with parchment paper and pour wings onto them. Broil until crispy, 5 minutes.
Return to the sauce in the Crock-pot to coat again then add wings to plates.
Serve warm with ranch dressing for dipping.
