Why make those pre-packaged boxed hamburger casseroles when you can make your own? It is much healthier and tastier to start from scratch with fresh ingredients that you can trust. It is almost just as easy too!
3 pounds red potatoes, washed, peeled and sliced 1/4-inch thick
salt
Canola oil, to grease pan
1 lb. lean ground beef
1/2 onion, chopped
4 T. butter
1/4 c. all-purpose flour
a couple dashes Worcestershire Sauce
pepper
2 c. milk
2 c. sharp Cheddar cheese, grated
1/2 c. unseasoned dry breadcrumbs
Place potatoes in a large saucepan with salted water and completely cover by 1 inch. Cook for 15 minutes, or until fork tender, don't overcook. Drain potatoes and arrange in a greased 6x9x2 inch casserole dish.
Grease a large skillet. Cook beef and onion together over medium heat until beef is browned and onion is softened, about 10 minutes. Drain excess fat.
Preheat oven to 350 degrees.
Melt butter in a medium saucepan, whisk in flour to make a roux and add Worcestershire Sauce. Cook over medium heat, whisking constantly, until mixture bubbles and flour turns light brown. Gradually whisk in milk, continue to stir while cooking over medium heat. When mixture thickens, season with salt and pepper, then stir in cheese and beef and onions.
Pour beef mixture over potatoes and bake for 20 minutes, until heated through and bubbling. Sprinkle breadcrumbs on top and bake until crumbs are toasted, about 5 minutes longer.
