Preheat oven to 350°F (177ºC). Butter a 9x5-inch loaf pan, or spray with non-stick cooking spray; set aside.
In a small mixing bowl, add butter (1/2 cup), garlic (1 tablespoon), Italian seasoning (2 teaspoons), and salt (1/4 teaspoon). Whisk until evenly combined; set aside.
Remove biscuits from tube and separate into individual biscuits. Split each biscuit in half. You will have 16 halves.
Dip each biscuit half into the garlic butter, taking care to completely cover the surface.
Sprinkle an even layer of shredded mozzarella over garlic butter, about 1 tablespoon. Repeat with the remaining biscuit halves, stacking them vertically, on top of one another. You will make two stacks of 8 tall.
Place the 2 stacks together, horizontally, in the prepared loaf pan so they reach end to end in the pan.
Brush the top of the loaf with the remaining garlic butter and sprinkle with Parmesan cheese and any leftover mozzarella.
Cover the loaf pan with aluminum foil and bake in the preheated for 40 minutes. Uncover and discard foil, then continue baking for 18-20 minutes. The bread should be golden brown.
Set the loaf pan on a wire baking rack and cool for 10 minutes. Sprinkle with fresh parsley and serve!
