1- First Step: Warm 1 cup milk to 110°F test with finger, should feel warm not hot. Stir in 1 packet yeast and 2 tbsp sugar. Let sit 5-10 minutes until foamy. This proves yeast is alive; dead yeast ruins rise. In a large bowl, combine 3 cups flour and 1 tsp salt. Pour in yeast mixture and 1/4 cup melted butter. Mix with a spoon until shaggy, then knead by hand 5-7 minutes on floured surface. Dough turns smooth and elastic, pulling away from bowl. If sticky, add 1 tbsp flour. Place in greased bowl, cover with damp cloth, rise in warm spot 1 hour until doubled.

2- Second Step: While dough rises, soften 1/2 cup butter to room temperature. Mince 6 garlic cloves finely use press for ease. Chop 1/2 cup parsley. Shred 1 cup mozzarella if not pre-shredded. Grate 1/4 cup Parmesan. Mix all in bowl until paste-like. Taste; add pinch salt if needed. This filling spreads evenly, preventing dry spots.

3- Third Step: Punch down risen dough. Roll into 12×16-inch rectangle on floured surface, about 1/4-inch thick. Evenly spread garlic butter mixture to edges, leaving 1-inch border on one long side. Sprinkle cheeses and parsley over butter. Press lightly to adhere.

4- Fourth Step: Roll tightly from long side into log, pinching seam. Use pizza cutter or serrated knife for 12 even 1.5-inch slices. For clean cuts without squishing, try unflavored dental floss: slide under log, cross, and pull. Grease 9×13 pan, place rolls cut-side up, touching slightly.

5- Fifth Step: Cover pan loosely, rise 30-45 minutes until puffy. Rolls expand, filling pan. Preheat oven now to 375°F.

6- Final Step: Bake 22-25 minutes until tops golden brown, internal temp 190°F. Melt 2 tbsp butter with 1 minced garlic clove, brush over hot rolls. Cool 5 minutes in pan, then pull apart. Serve warm with marinara or as is. Store leftovers per guidelines below. Pro tip: Tent foil if browning too fast.
