A simple, hearty casserole featuring ground beef, egg noodles, and a creamy sour cream sauce, baked until golden brown.

Ingredients

Scale
  • 1 pound ground beef
  • 1 medium onion, chopped
  • 1 can (10.5 ounces) cream of mushroom soup
  • 1 cup sour cream
  • 1 cup shredded cheddar cheese, divided
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 12 ounces egg noodles
  • 1/2 cup milk

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Cook the ground beef and onion in a large skillet over medium heat until the beef is browned and the onion is soft. Drain off any excess grease.
  3. Stir the cream of mushroom soup, sour cream, 1/2 cup of the cheddar cheese, salt, pepper, and garlic powder into the beef mixture. Mix well.
  4. Cook the egg noodles according to package directions until al dente. Drain the noodles well.
  5. In a large bowl, combine the cooked noodles, the beef mixture, and the milk. Mix gently until everything is coated.
  6. Pour the noodle mixture into the prepared baking dish. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
  7. Bake for 25 to 30 minutes, or until the casserole is bubbly and the cheese is melted and lightly browned.
  8. Let the casserole rest for 5 minutes before serving.

Notes

  • For a richer flavor, substitute cream of celery soup for the cream of mushroom soup.
  • You can prepare this casserole completely, cover it, and refrigerate it for up to 24 hours before baking. Add 10 minutes to the bake time if cooking from cold.
  • Use wide egg noodles for the best texture in this dish.
