Description

This rich and savory French Onion Beef Casserole blends seasoned ground beef, tender egg noodles, classic French onion soup flavors, and a cheesy topping for the ultimate comforting family dinner. Perfect for cozy evenings, this casserole layers creamy mushroom soup, sour cream, and two kinds of cheese for a hearty, flavorful meal.

Ingredients

Beef Mixture

  • 1 lb ground beef
  • 1 packet French onion soup mix
  • ½ cup beef broth
  • 1 tbsp butter

Noodles and Sauces

  • 12 oz egg noodles
  • 1 can cream of mushroom soup (10.5 oz)
  • 1 cup sour cream

Cheeses

  • 1½ cups shredded mozzarella cheese
  • 1 cup shredded Swiss cheese

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s ready to bake the casserole once assembled.
  2. Cook Noodles: Boil the egg noodles according to package directions until al dente, then drain thoroughly to avoid excess moisture in the casserole.
  3. Brown Beef: In a skillet over medium heat, cook the ground beef until fully browned, breaking it up as it cooks, then drain off any excess grease for a leaner dish.
  4. Season Beef: Stir in the French onion soup mix and beef broth into the browned beef. Simmer this mixture for about 3 minutes to let the flavors meld together.
  5. Mix Ingredients: In a large bowl, combine the cream of mushroom soup, sour cream, cooked egg noodles, and the beef mixture. Mix thoroughly until everything is well incorporated.
  6. Assemble Casserole: Transfer the combined mixture into a greased 9×13-inch baking dish, spreading evenly.
  7. Add Cheese and Butter: Top the casserole evenly with shredded mozzarella and Swiss cheeses. Dot the surface with small pieces of butter for extra richness.
  8. Bake: Place the casserole uncovered in the preheated oven and bake for 25–30 minutes, until the cheese is melted, bubbly, and golden.
  9. Rest and Serve: Allow the casserole to rest for 5 minutes after baking to set before serving, enhancing flavors and ease of serving.

Notes

  • Gruyère cheese can be substituted for Swiss cheese to deepen the classic French onion flavor.
  • Garnish with fresh parsley prior to serving to add a bright, fresh touch.
  • You can freeze the casserole before baking for up to 2 months; bake from frozen adding extra baking time as needed.
