Ingredients

Scale

Main Protein:

  • 1 pound (454 grams) ground beef

Dairy and Cheese:

  • 2 cups shredded mozzarella or Swiss cheese
  • 1/2 cup sour cream
  • 1 tablespoon olive oil

Soup and Seasoning Ingredients:

  • 1 packet (1 ounce) French onion soup mix
  • 1 can (10.5 ounces) cream of mushroom soup
  • 1/2 cup beef broth
  • 1 medium onion, thinly sliced
  • 2 cups egg noodles, cooked
  • Salt and pepper to taste
  • Chopped parsley for garnish (optional)

Instructions

  1. Warmly prepare the oven to 350F (175C), ensuring a perfectly heated cooking environment.
  2. Gently caramelize sliced onions in a large skillet with olive oil over medium heat, developing rich golden-brown color for 10-12 minutes.
  3. Introduce ground beef to the skillet, browning thoroughly and carefully draining any accumulated fat.
  4. Infuse the meat with robust flavor by mixing French onion soup mix and beef broth, allowing the ingredients to meld for 2-3 minutes.
  5. Create a creamy base in a large mixing bowl by combining cream of mushroom soup and sour cream with cooked noodles.
  6. Fold the seasoned beef and caramelized onion mixture into the creamy noodle combination, ensuring even distribution of ingredients.
  7. Carefully transfer the mixed casserole contents into a generously greased 9×13-inch baking dish, spreading evenly.
  8. Sprinkle a generous layer of shredded cheese across the top, creating a golden, melty surface.
  9. Bake for 25-30 minutes until the cheese transforms into a bubbling, golden-brown crust.
  10. Finish by scattering fresh chopped parsley over the casserole for a vibrant, aromatic touch before serving.

Notes

  • Slow-caramelize onions by stirring frequently and reducing heat to prevent burning, creating deeper flavor complexity.
  • Drain ground beef thoroughly to minimize excess grease and maintain a lighter, less heavy casserole texture.
  • Choose low-sodium French onion soup mix and beef broth to control salt levels, especially for health-conscious diners.
  • Swap regular noodles with whole wheat or gluten-free alternatives to accommodate different dietary restrictions without compromising taste.
