Old-Fashioned Potato-Beef Casserole

READY IN: 55mins




  • Place the potatoes in a large saucepan with water to cover by 1 inch.
  • Add a generous pinch of salt and cook for 15 minutes, or until tender; do not overcook.
  • Drain the potatoes and arrange them in a 9 x 9 inch casserole dish.
  • While potatoes are cooking, in large skillet, combine the beef and onion and cook together over medium heat until the beef is browned and the onion softened, 12-15 minutes.
  • Pour off excess fat.
  • Preheat oven to 350 degrees.
  • Melt the butter in a medium saucepan and whisk in flour to make a roux.
  • Cook over medium heat, whisking constantly, until the mixture bubbles and the flour turns light brown in color.
  • Gradually whisk in the milk and continue to stir while cooking over medium heat.
  • When the mixture thickens, whisk in the salt and pepper, then stir in the cheese and browned beef.
  • Pour the ground beef mixture over the potatoes and bake the casserole for 20 minutes until heated through and bubbling.
  • Stir the casserole gently.
  • Sprinkle a little more cheddar cheese on top, if desired, and the bread crumbs on top of the casserole and bake until the crumbs are toasted, about 5 minutes longer.
