Questions Readers Ask Most

Yes. Assemble the casserole without the mozzarella and crispy fried onions, cover, and refrigerate for up to 24 hours. When ready to bake, add the mozzarella and bake as directed, adding the crispy onions during the last 5–10 minutes.

Yes. For best results, freeze the casserole without the crispy fried onion topping. Wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator, then add the cheese and crispy onions when baking.

Yes. This casserole is a great way to use leftover cooked ground beef. You’ll need about 1½ pounds of cooked beef. Simply warm it before combining it with the soups and remaining filling ingredients.

The most common cause is using too many noodles or overbaking. Stick with 12 ounces of egg noodles and bake just until the casserole is hot and bubbly and the cheese has melted.

Let the casserole cool, then transfer it to an airtight container and refrigerate for up to 4 days.

Reheat individual servings in the microwave or cover and warm in a 350°F oven until heated through. For the best crunch, add a few fresh crispy fried onions after reheating. 🧅🥩🧀

Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes

Ingredients

  • 12 oz bag of egg noodles
  • 1.5 pounds ground beef
  • 1 can 10oz cream mushroom soup
  • 1 can 10 oz French Onion soup
  • 1 cup sour cream
  • 1 cup green beans (I used frozen)
  • 8 oz Mozzarella cheese
  • 1 cup Crispy french onions

Instructions

  1. Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish.

  2. Cook the egg noodles according to the package directions until al dente. Drain and set aside.

  3. In a large skillet over medium heat, cook the ground beef until browned and crumbled. Drain any excess grease.

  4. Reduce the heat to low and stir in the cream of mushroom soup and French onion soup until well combined.

  5. Stir in the sour cream and frozen green beans.

  6. Add the cooked egg noodles and gently stir until everything is evenly coated in the creamy sauce.

  7. Transfer the mixture to the prepared baking dish and spread it into an even layer.

  8. Sprinkle the mozzarella cheese evenly over the top.

  9. Bake uncovered for 20 minutes.

  10. Sprinkle the crispy French fried onions over the cheese and return to the oven for 5–10 minutes, or until the casserole is hot and bubbly, the cheese is melted, and the onions are golden and crispy.

  11. Let the casserole rest for 5 minutes before serving.

Notes

Cook the egg noodles just until al dente since they'll continue cooking in the oven. Be sure to drain the ground beef well before adding the soups. Use 12 ounces of egg noodles for the best sauce-to-noodle ratio. Add the crispy French fried onions during the last 5–10 minutes of baking so they stay golden and crunchy. Let the casserole rest for about 5 minutes before serving.
