Heat an oven safe skillet over medium heat on the stove top. Melt the butter and sauté the garlic until fragrant, about 30 seconds. Add in the chicken and Frank's RedHot Sauce and bring to a simmer for 3 minutes.
Add in the cream cheese and stir over medium heat until it's incorporated into the sauce. Remove the skillet from the heat and stir in the ranch dressing.
Top the chicken dip with the freshly shredded cheese. Bake in the oven for 10 minutes, or until bubbly throughout. Turn on the top broiler and cook an additional minute to brown the top of the dip slightly.
Remove from the oven and garnish with chopped green onions. Serve with crackers, celery, crusty bread, or chips. Enjoy!
