Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking pan with non-stick cooking spray.

Bring a large pot of salted water to a boil and cook the dried egg noodles according to package directions until al dente, usually about 7-9 minutes. Drain and set aside.

In a large skillet over medium-high heat, add the lean ground beef. Cook until browned and no longer pink, around 6-8 minutes. Season with salt and pepper to taste, then drain excess fat.

Stir in two cans of condensed cream of mushroom soup and one jar of French onion dip with the cooked beef. Mix well and let simmer on low for a few minutes.

Gently fold the cooked egg noodles into the beef mixture, ensuring all noodles are coated.

Pour the noodle and beef mixture into the prepared baking pan, spreading evenly.

Sprinkle half a cup of French's fried onions on top of the casserole.

Bake uncovered for about 20 minutes, until the edges are bubbling and the onions are golden.

Let the casserole cool for a few minutes before serving.
