Chef’s Note:
Instead of a bread crouton as you’d find in French Onion Soup, egg noodles will do the job of soaking up the savory sauce. Simmering the chopped meat in beef broth with onions, seasonings, and thyme will infuse the meat with flavor, creating a rich filling for your noodle bake. It also tenderizes the meat so that it is fall-apart succulent, and the caramelized onions have an almost buttery flavor, both of which taste amazing with the added mushrooms.
Baking Tips & Tricks
We use mozzarella cheese for this French Onion Beef Noodle Bake because it has a mild flavor and it melts beautifully. This classic soup uses Gruyere cheese, but using all Gruyere would likely overpower the other flavors of this dish. If you’d like a stronger cheese flavor, I suggest replacing only half of the shredded mozzarella with another type of cheese, such as shredded Gruyere, Swiss, or provolone. By combining another cheese with the remaining mozzarella, you’ll still achieve a nicely melted, classic golden brown topping.
What to Pair with French Onion Noodle Bake
French Onion Beef Noodle Bake would be excellent served with a fresh, crunchy salad or a green vegetable, like Roasted Broccoli or Sautéed Green Beans, on the side. To make this meal even more special, follow it with a simple dessert like Chocolate Cake or Vanilla Ice Cream with Salted Caramel Sauce.

Instead of beef broth, I use dry onion soup mix (I make my own) & Shillings “Montreal Steak Seasoning”. I get *tons* of compliments & “recipe” requests. I consider it cheating, since I’m a retired Dietitian & Chef, but hey….it works!!!
Made this for dinner last night using leftover beef brisket. I didn’t have egg noodles, but I did have papardell, which is an excellent substitute. Great recipe and one I’ll definitely make again. Thanks so much for sharing this one.
