  • 1 cup (240 milliliters) beef broth
  • 1 tablespoon Worcestershire sauce

Dairy and Cheese Ingredients:

  • 1 1/2 cups (170 grams) shredded mozzarella cheese
  • 1 cup (113 grams) shredded cheddar cheese
  • 1 cup (240 milliliters) sour cream
  • 1 tablespoon (14 grams) butter

Vegetable and Seasoning Ingredients:

  • 1 large yellow onion
  • 1 can (10.5 ounces or 298 grams) condensed French onion soup
  • 1 can (10.5 ounces or 298 grams) cream of mushroom soup
  • 2 cups (224 grams) cooked egg noodles or pasta
  • 1 teaspoon garlic powder
  • Salt and pepper to taste
  • 1 tablespoon fresh parsley
  • French fried onions or breadcrumbs (optional)

Instructions

  1. Preheat oven to 350°F, ensuring proper temperature for optimal casserole preparation.
  2. Caramelize onions in butter over medium heat until rich golden brown and deeply fragrant, approximately 15-20 minutes.
  3. In the same skillet, thoroughly brown ground beef, carefully draining any excess fat to maintain a clean flavor profile.
  4. Combine caramelized onions with browned beef, then integrate French onion soup, cream of mushroom soup, beef broth, Worcestershire sauce, and garlic powder, creating a robust flavor base.
  5. Gently fold cooked egg noodles into the meat mixture, ensuring even distribution of ingredients.
  6. Season the casserole blend with salt and pepper, adjusting to personal taste preferences.
  7. Transfer the entire mixture into a generously greased casserole dish, spreading evenly for consistent cooking.
  8. Liberally sprinkle mozzarella and cheddar cheese across the top, creating a golden, melty surface.
  9. For added texture, incorporate sour cream and generously scatter French fried onions or breadcrumbs over the cheese layer.
  10. Bake for 20-25 minutes until cheese transforms into a bubbling, golden-brown crust and casserole is heated through completely.
  11. Garnish with fresh parsley for a vibrant finish, serving immediately while warm and aromatic.

Notes

  • Caramelize onions slowly over medium-low heat to develop deep, rich flavor without burning.
  • Use lean ground beef to reduce excess grease and create a cleaner, more refined casserole texture.
  • Add a splash of red wine or beef broth while cooking onions to enhance their natural sweetness and complexity.
  • For gluten-free option, substitute egg noodles with zucchini noodles or gluten-free pasta varieties to maintain dish’s hearty character.
