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
- 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.
- 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.
- 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.
- Drain excess fat from the beef. Sprinkle 1 teaspoon salt, ½ teaspoon black pepper, and 1 tablespoon Worcestershire sauce over the meat mixture.
- 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.
- Fold 2 cups shredded Gruyere cheese into the mixture. Transfer everything to the prepared baking dish.
- Top the casserole with 1 cup crispy fried onions, spreading them evenly across the surface.
- Bake uncovered at 350°F for 20-25 minutes until the top turns golden and edges bubble.
- 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.
