1 clove garlic (minced)
1.25 tsp salt (for seasoning)
1/2 tsp ground black pepper (for seasoning)
3/4 cup chicken stock (for sauce)
1.25 cups heavy cream (for creamy texture)
1.5-1.75 lbs russet potatoes (about 5-6, peeled and sliced 1/8 inch thick)

1 tbsp chopped parsley (for garnish)
Directions:
