How to Make It
Prepare the Cheese Bread: Preheat oven to 400°F. Remove dough from refrigerator; let stand at room temperature 20 minutes. Roll dough on a lightly floured surface into a 32- x 3-inch rectangle. Tear cheese sticks in half lengthwise. Place cheese pieces in a single layer lengthwise down center of dough rectangle, leaving 1 inch of dough along each side. Sprinkle 1/2 cup of the Parmesan evenly on cheese pieces. Bring sides of dough up and over cheese. Using moistened fingers, pinch to seal seam and form a tube shape. Bring ends together to form a 12-inch ring, and pinch ends to seal tightly. Carefully place ring, seam side down, on a baking sheet sprinkled with cornmeal. Brush top of ring with 1 tablespoon of the oil. Bake in preheated oven until golden brown, 12 to 14 minutes.
Meanwhile, combine butter, parsley, garlic powder, salt, and remaining 3 tablespoons oil and 2 tablespoons Parmesan in a bowl. When bread is removed from oven, brush with butter mixture.
Prepare the Ranch Dipping Sauce: Stir together mayonnaise, buttermilk, dill, garlic powder, onion powder, salt, and pepper in a serving bowl until smooth; swirl in marinara. Place cheese bread on a platter with bowl of dipping sauce in the middle. Dip away!!
