Heat oven to 375°F. Spray small baking dish with cooking spray. On lightly floured surface, unroll dough into 1 large rectangle; press perforations and edges to seal.
Place cream cheese on center of dough. Sprinkle dill to cover top of cheese. Turn cheese over, dill side down. Bring dough up around cheese, pinching seams to seal. Place dough-covered cheese, seam side down, in baking dish.
Brush with beaten egg. If desired, cut out additional dough to decorate top.
Bake 15 to 20 minutes or until golden brown. Serve with crackers.
