PLACE dough on lightly floured surface; knead until smooth and elastic, adding some of the remaining 1/4 cup flour if dough is too moist. Cover dough; let rest 10 min. Shape into ball. Place on well-greased baking sheet; cover loosely with plastic wrap. Let rise in warm place 45 min. or until doubled in volume. Uncover.
PREHEAT oven to 350°F. Bake 40 to 45 min. or until bread is golden brown. Immediately remove to wire rack. Cool completely. Cut into slices to serve.
