                    This homey gratin partners nicely with pork or other grilled meats. Dotting the top with butter adds richness. Ingredients: 
                    
                        
                                                6 baking potatoes, peeled and thinly sliced (about 3 1/2 pounds)  |  
                                                cooking spray  |  
                                                1 1/4 cups thinly sliced onion (about 1 medium)  |  
                                                1 1/2 teaspoons freshly ground black pepper, divided  |  
                                                3/4 teaspoon salt, divided  |  
                                                1/2 cup (2 ounces) shredded gruyère cheese  |  
                                                2 tablespoons butter, chilled and cut into small pieces  |  
                                                3/4 cup fat-free, less-sodium beef broth  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Preheat oven to 375°. 2. Arrange one-third of potato slices in the bottom of a shallow 2-quart baking dish coated with cooking spray. Top with one-third of onion slices. Sprinkle with 1/2 teaspoon pepper and 1/4 teaspoon salt. Sprinkle with one-third of cheese. Repeat layers twice, ending with cheese. Dot with butter. Pour broth over potato mixture. Coat top layer with cooking spray. Cover with foil, and bake at 375° for 30 minutes. Uncover and bake an additional 30 minutes or until tender.                              |
