Preheat your oven to 350°F and grease a 9x13-inch baking dish with non-stick spray.
Bring a large pot of water to a boil and cook the egg noodles according to the package directions. Drain the noodles and set them aside.
While the noodles cook, brown the ground beef in a large skillet over medium-high heat until fully cooked. Season with salt and pepper, then drain any excess fat.
Stir in the cream of mushroom soup and French onion dip with the cooked beef, combining everything evenly.
Gently mix the drained noodles into the beef mixture until everything is well combined.
Pour the beef and noodle mixture into the prepared baking dish, spreading it evenly.
Evenly sprinkle the crispy fried onions on top of the casserole.
Bake, uncovered, in the preheated oven for about 20 minutes, or until the casserole is hot and bubbly.
Garnish with freshly chopped parsley if desired. Serve warm and enjoy!
