How to Make Simple French Onion Beef Casserole
Follow these simple steps to prepare this delicious Simple French Onion Beef Casserole:
Step 1: Brown the Beef
In a skillet over medium heat, brown the ground beef until it’s no longer pink. Season with salt and pepper, then drain the excess grease to keep things from getting too heavy.
Step 2: Boil the Noodles
While the beef is cooking, bring a pot of salted water to a boil. Add the egg noodles and cook according to the package directions, usually around 7-9 minutes. Drain and set aside, but don’t rinse—those starchy bits help the sauce cling.

Step 5: Assemble the Casserole
Spread the mixture evenly into a greased 9×13-inch baking dish. If you’re feeling cheesy, sprinkle shredded cheese on top—this optional step is a game changer for cheese lovers.
Step 6: Add the Crunch
Sprinkle the French fried onions evenly over the top. This crunchy layer not only looks inviting but also adds a delightful texture that will have everyone coming back for seconds.
Step 7: Bake
Pop the dish in a preheated oven at 350°F (175°C) and let it bake for about 25–30 minutes. You’ll know it’s ready when the dish is bubbling and the top is golden and crispy.
Step 8: Serve and Enjoy
