Ingredients

Scale

Main Ingredients:

  • 1 lb lean ground beef
  • 2 cup shredded Gruyere or Swiss cheese
  • 1 cup cooked egg noodles
  • 1 can (10.5 ounce) cream of mushroom soup
  • 2 large onions, thinly sliced

Supporting Ingredients:

  • 1 cup beef broth
  • 1 cup sour cream
  • 2 tablespoon butter
  • 1 tablespoon Worcestershire sauce
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon dried thyme

Optional/Topping Ingredients:

  • 1 cup crispy fried onions
  • 1 cup sliced mushrooms
  • ½ cup cooked crumbled bacon
  • ¼ cup red wine
  • Fresh parsley, chopped

Instructions

  1. Preheat the oven to 350°F and coat a 9-inch baking dish with cooking spray. Your casserole needs a non-stick surface for easy serving.
  2. Melt 2 tablespoons butter in a large skillet over medium heat. Sauté 2 thinly sliced onions until they turn deep golden brown, approximately 8-10 minutes.
  3. Add 1 lb lean ground beef to the caramelized onions. Break the meat into small crumbles while cooking until no pink remains, about 6-7 minutes.
  4. Drain excess fat from the beef. Sprinkle 1 teaspoon salt, ½ teaspoon black pepper, and 1 tablespoon Worcestershire sauce over the meat mixture.
  5. In a large mixing bowl, combine 1 cup cooked egg noodles, beef mixture, 1 cup beef broth, 1 can cream of mushroom soup, and 1 cup sour cream. Stir until ingredients are evenly distributed.
  6. Fold 2 cups shredded Gruyere cheese into the mixture. Transfer everything to the prepared baking dish.
  7. Top the casserole with 1 cup crispy fried onions, spreading them evenly across the surface.
  8. Bake uncovered at 350°F for 20-25 minutes until the top turns golden and edges bubble.
  9. Remove from oven and let the casserole rest for 5 minutes. Garnish with chopped fresh parsley before serving.

Notes

  • Caramelize onions slowly over medium-low heat to develop deep, rich flavor without burning them.
  • Replace egg noodles with gluten-free alternatives or zucchini noodles for low-carb diets.
  • Use lean ground beef or ground turkey to reduce overall fat content while maintaining delicious taste.
  • Add fresh thyme or rosemary during beef browning for an extra layer of herbal complexity in the dish.
