Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Ground beef
Ground beef forms the hearty foundation of this casserole. It provides richness and structure while absorbing the savory onion flavors beautifully. I recommend using lean ground beef to avoid excess grease.

Egg noodles
Egg noodles add a tender yet slightly chewy texture that holds up well during baking. Their mild flavor allows the sauce to shine without becoming heavy.

French onion soup mix
This ingredient delivers concentrated onion flavor and seasoning in one step. It mimics the depth of traditional caramelized onions without the extra cooking time.

Cream of mushroom soup
Cream of mushroom soup creates a creamy, cohesive sauce that binds the casserole together. It adds subtle earthiness and balances the onion flavors.

Sour cream
Sour cream contributes tanginess and a velvety texture. I tested this once with Greek yogurt, and while it worked, sour cream gives the best classic result.

Beef broth
Beef broth enhances the savory profile and prevents the casserole from drying out while baking.

Shredded mozzarella cheese
Mozzarella melts smoothly and creates a stretchy, comforting topping. It also helps seal in moisture.

Grated Parmesan cheese
Parmesan adds a salty, nutty finish that deepens the overall flavor.

Butter
Butter enriches the sauce and adds a subtle sweetness that complements the onion seasoning.

Salt and black pepper
These simple seasonings help balance and enhance the existing flavors.

Directions

Begin by preheating your oven to 180°C (350°F) and lightly greasing a large casserole dish. Bring a pot of salted water to a boil and cook the egg noodles according to package instructions until just al dente. Drain and set aside.

In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it up as it cooks. Drain any excess fat. Stir in the French onion soup mix and butter, allowing the mixture to become fragrant.

Add the cream of mushroom soup, sour cream, and beef broth to the skillet. Stir until the sauce is smooth and well combined. Season lightly with black pepper and taste before adding extra salt, as the soup mix is already seasoned.

Fold the cooked noodles into the beef mixture, ensuring everything is evenly coated. Transfer the mixture to the prepared casserole dish. Sprinkle mozzarella and Parmesan evenly over the top.

Bake uncovered for 25 to 30 minutes, or until the cheese is melted and bubbling. Allow the casserole to rest for 5 minutes before serving to help it set.

Storage/reheating

Variations and Customizations

This casserole is easy to adapt based on your preferences or what you have available. For a lighter version, you can substitute ground turkey or ground chicken for the beef. I have tried it with turkey, and the onion flavor still comes through beautifully.

If you enjoy vegetables, sautéed mushrooms, peas, or spinach can be folded into the mixture before baking. These additions add texture and balance the richness of the sauce.

Cheese options are also flexible. Swiss cheese pairs exceptionally well with the French onion profile, while provolone offers a mild, creamy alternative. For extra depth, a combination of cheeses works well.

To make the dish more indulgent, top it with crispy fried onions during the last 10 minutes of baking. For a lower-carb option, replace the noodles with cooked cauliflower florets, though the texture will be softer.
