Open the can of biscuits and peel the biscuits apart. Cut each biscuit lengthwise and then widthwise making 4 equal-sized pieces.
In a large bowl combine undrained tomatoes, bacon, cream cheese, and ranch dressing. Stir together until well mixed.
Add the shredded chicken and half of the biscuits to the mixture and toss together gently. You don’t want to crush the biscuit dough.
Place mixture in the greased baking dish and top with the remaining biscuits placing them evenly over the chicken mixture and nestling them into the mixture so they are halfway in.
Bake for 25 minutes.
When it has baked 25 minutes place your butter in a microwave safe dish and microwave for 30 seconds. Add the ranch seasoning to the butter and mix together.
Open the oven and brush the butter over the tops of the exposed biscuits. Sprinkle the cheddar cheese over the casserole and then close the oven and let it continue to bake for 10 minutes longer.
Remove from the oven and let it rest for 10 minutes before serving.
