Step-by-Step Cooking Instructions

Follow these simple steps to create a perfect French Onion Beef Casserole:
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with cooking spray or butter.
2. Cook the Egg Noodles
Cook the egg noodles according to the package instructions until al dente. Drain and set aside.
3. Caramelize the Onions
In a large skillet, heat olive oil over medium heat. Add the thinly sliced onions and cook, stirring frequently, for 15-20 minutes until the onions are golden brown and caramelized. Season with a pinch of salt and pepper, then add the minced garlic and cook for another 1-2 minutes. Remove the onions from the skillet and set aside.
4. Brown the Ground Beef
In the same skillet, add the ground beef and cook over medium heat until browned, breaking it up with a spatula as it cooks. Drain any excess fat. Stir in the Worcestershire sauce, onion soup mix, and season with salt and pepper to taste.
5. Make the Sauce
In a large mixing bowl, combine the condensed French onion soup, beef broth, sour cream, and heavy cream. Stir until smooth. Add the cooked noodles and beef mixture to the sauce and mix well.
6. Assemble the Casserole
In the prepared baking dish, spread half of the caramelized onions across the bottom. Add the beef and noodle mixture on top of the onions, spreading it out evenly. Top with the remaining caramelized onions.
7. Add Cheese and Crispy Topping
Sprinkle shredded Swiss cheese over the casserole, then top with crispy fried onions for added crunch and flavor.
8. Bake
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly and the top is golden brown.
9. Let It Rest
Once baked, allow the casserole to rest for 5-10 minutes before serving. This helps the flavors meld and makes it easier to cut and serve.

Common Mistakes to Avoid
Here are some common mistakes to avoid when making French Onion Beef Casserole:

- Overcooking the Pasta: Make sure to cook the egg noodles until just al dente, as they will continue to cook in the oven.
- Not Draining the Beef: After browning the beef, drain any excess fat to avoid a greasy casserole.
- Burning the Crispy Onions: Keep an eye on the casserole in the last few minutes of baking to ensure the crispy fried onions don’t burn. If necessary, cover the casserole with foil to prevent over-browning.
