1Heat oven to 350°F. In 8-inch skillet, melt butter over medium heat. Add onions and garlic; cook 5 to 8 minutes, stirring occasionally, until onions are tender. Remove from heat; cool slightly. Stir in parsley.
2Separate dough into 8 biscuits. Spoon onion mixture on 1 side of each biscuit. In ungreased 8x4- or 9x5-inch loaf pan, stand biscuits on rounded edge, with plain side of end biscuits toward pan.
3Bake 8x4-inch pan 50 to 60 minutes, 9x5-inch pan 35 to 45 minutes, or until deep golden brown. Cover with foil during last 10 to 15 minutes of baking to prevent excessive browning. Immediately remove from pan. Serve warm.
