Onions Au Gratin
  • 1/4 cup butter
  • 6 yellow onions, halved and sliced 1/2 inch thick
  • 1/2 cup beef broth
  • 1/2 cup heavy cream
  • 2 tablespoons all-purpose flour

  • 1/8 teaspoon pepper
  • 1/2 cup shredded Swiss cheese

  1. Preheat the oven to 350 degrees F (175 degrees C). Grease an 8 inch square baking dish.

In a medium bowl, stir together the beef broth and flour until smooth. Mix in the cream and season with salt and pepper; pour over the onions. Sprinkle Swiss cheese and Parmesan cheese over the top.
  3. Bake for 25 to 30 minutes in the preheated oven, until cheese is golden brown and the sauce is bubbly.
