Cook onions in large nonstick skillet on medium heat 5 to 7 min. or until crisp-tender, stirring frequently. Add cooking creme, broth, 1 cup cheese and parsley; mix well. Remove from heat. Gently stir in potatoes.
Spoon into 13x9-inch baking dish sprayed with cooking spray.
Bake 45 min. Top with remaining cheese; bake an additional 10-15 min. or until potatoes are tender. Let stand 5 min. before serving.
Special Extra: For added color and flavor, substitute a sweet potato for 1 of the red potatoes.
How to Slice Potatoes Evenly: When thinly slicing a large amount of potatoes, use a food processor or manual slicer (mandoline) for even results. Place the sliced potatoes into a bowl of cold water until ready to cook to prevent them from darkening.
Serving Suggestion: This savory side makes a perfect accompaniment to grilled or baked poultry.
