French onion ground beef casserole is an easy and hearty casserole filled with hamburger, onions, sour cream, cream of mushroom soup, noodles, and crispy fried onions great for a busy weeknight dinner.
Brown the ground beef over medium heat with the Worcestershire sauce. When almost completely cooked, add the diced onions and onion seasoning mix. Stir and cook until beef is completely browned.
While the beef is browning, cook the wide egg noodles for two minutes less than the package instructions. Drain and then add the soup, sour cream, and milk to the noodles.
Stir the beef and onion mixture to the noodles. Mix to combine and then transfer to a greased lasagna pan or 13X9 baking dish. Top with crispy fried onions.
