Step 1

Cook the noodles according to the package directions.

Step 2

Brown the ground beef along with the onion. Drain the fat off the meat.

Step 3

In a large bowl, combine the noodles, beef, peas, soups and sour cream. Pour the mixture into a greased 9x13 (or even a bit larger) greased baking dish.

Step 4

In a small bowl, toss the breadcrumbs with the melted butter. Sprinkle the breadcrumbs on top of the casserole. The pan will be very full.

Step 5

Cover the casserole with foil and bake the casserole in a 350 degree oven for 25 minutes, then uncover and bake an additional 15-20 minutes, or until is heated through and lightly browned on top.

Step 6

Serve immediately.
