Ingredients
For the Casserole
- 1 lb (450 g) ground beef
- 1 medium yellow onion, thinly sliced
- 8 oz (225 g) egg noodles
- 2 cloves garlic, minced
- 1 can (10.5 oz) condensed French onion soup
- 1 can (10.5 oz) cream of mushroom soup
- ½ cup sour cream
- ½ cup beef broth
- 1½ cups shredded mozzarella cheese
- ½ cup shredded Parmesan cheese
- 1 tbsp butter
- 1 tsp Worcestershire sauce
- 1 tsp Italian seasoning
- ½ tsp garlic powder
- ½ tsp onion powder
- Salt, to taste
- Black pepper, to taste
- 1 tbsp chopped fresh parsley, for garnish
Instructions
1. Cook the noodles
Bring a large pot of salted water to a boil. Cook the egg noodles according to the package directions until just al dente.
Drain well and set aside. Avoid overcooking because the noodles will continue cooking in the oven.
2. Caramelize the onions
Heat the butter in a large skillet over medium heat.
Add the sliced onion and cook for about 8–12 minutes, stirring occasionally, until softened and golden brown.
Add the minced garlic and cook for another 30–60 seconds.
3. Brown the ground beef
Add the ground beef to the skillet with the onions.
Cook for 6–8 minutes, breaking the beef apart with a wooden spoon, until completely browned and cooked through.
Drain excess grease if necessary.
4. Season the beef
Stir in the Worcestershire sauce, Italian seasoning, garlic powder, onion powder, salt, and black pepper.
Cook for another minute so the seasonings blend into the beef.
5. Make the creamy French onion sauce
Reduce the heat to low.
Add the condensed French onion soup, cream of mushroom soup, sour cream, and beef broth.
Stir everything together until smooth and creamy.
Allow the mixture to simmer gently for 2–3 minutes. Do not let it boil aggressively.
6. Combine with the noodles
Add the cooked egg noodles to the skillet.
Gently stir until the noodles are completely coated with the beef and French onion sauce.
7. Assemble the casserole
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
Transfer the noodle and beef mixture into the dish and spread it evenly.
Sprinkle the shredded mozzarella over the top, followed by the Parmesan cheese.
8. Bake
Place the casserole in the preheated oven and bake uncovered for approximately 20–25 minutes, until hot and bubbling.
For an extra golden, crispy cheese topping, broil for 1–2 minutes at the end. Watch carefully so the cheese doesn’t burn.
9. Rest and serve
Remove the casserole from the oven and let it rest for 5 minutes.
Garnish with freshly chopped parsley and serve warm.
🔥 Tips for the Best Casserole
- Don’t overcook the noodles before baking; al dente gives the best texture.
- Caramelizing the onions until golden adds much more French onion flavor.
- For an extra cheesy casserole, add another ½ cup mozzarella on top.
- You can substitute ground beef with ground turkey if preferred.
- For a stronger French onion flavor, add ½ teaspoon dried thyme to the beef mixture.
- Let the casserole rest for a few minutes before serving so the sauce thickens slightly.
