Notes
Chicken: This recipe will work with chicken thighs as well. Adjust bake time accordingly.Ranch Seasoning: Be sure to use the seasoning mix and not the dip mix. The dip mix is more salty.Mayo: This does NOT taste like mayo after it's finished baking. Even mayo haters will enjoy this one. Don't sub the mayo for Miracle Whip.
