Directions See How It's Made
- 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.
