Step 1: Prepare the Pan and Butter
Preheat the oven to 375°F (190°C). Position the rack in the center of the oven.
Divide the butter into two equal portions (4 tablespoons each).
Use one portion to grease a standard loaf pan.
Line the pan with parchment paper, leaving 2–3 inches of overhang on the sides.
Melt the remaining 4 tablespoons butter in a small saucepan over medium heat until foamy.
Stir in the garlic, chives, and parsley.
Reduce heat to low and simmer for 5 minutes.
Remove from heat and set aside.
Step 2: Make the Biscuit Dough
In a large bowl, whisk together the flour, ⅓ cup Parmesan cheese, baking powder, baking soda, and garlic salt.
In a measuring cup, stir together the Greek yogurt and milk until smooth.
Using a box grater, grate the reserved cold butter directly into the flour mixture.
Toss gently to coat and distribute the butter pieces evenly.
Make a well in the center and pour in the yogurt mixture.
Stir gently until a dough forms. If needed, add additional milk or water, 1 tablespoon at a time, until combined.
Step 3: Create the Layers
Lightly flour a work surface and transfer the dough onto it.
Roll the dough into an 8 x 16-inch rectangle about ½-inch thick.
Fold the dough in half.
Roll back into a rectangle and repeat the folding process 5 more times, alternating directions for a total of 6 folds.
Brush the entire surface with the garlic herb butter.
Step 4: Assemble the Pull-Apart Bread
Cut the dough lengthwise down the center.
Cut each strip into 4 equal sections, creating 8 pieces total.
Fold each piece in half.
Stand the folded pieces upright in the prepared loaf pan, arranging them side by side.
Brush the top with most of the garlic butter mixture, reserving about 1 tablespoon.
Sprinkle with the remaining 1 tablespoon Parmesan cheese.
Step 5: Bake
Increase the oven temperature to 400°F (204°C).
Bake for 20–22 minutes, or until golden brown and fully baked through.
Remove from the oven and immediately brush with the reserved garlic butter.
Allow the bread to rest for 10 minutes.
Use the parchment overhang to lift the loaf from the pan.
Serve warm and enjoy.
