- 1 can (10.5 oz) French onion soup

- In a large mixing bowl, toss together the broccoli florets, French onion soup, sour cream, cheddar cheese, and mozzarella cheese. Make sure everything is well combined—it should look cheesy and inviting!
- Once mixed, transfer this delicious mixture into a greased baking dish. I like to use a 9×13-inch dish for the perfect fit, but any similar size will do!
- In another small bowl, combine the breadcrumbs and olive oil. Mix them together until the breadcrumbs are nicely coated; this will give your casserole that delightful crispy topping.
- Sprinkle the breadcrumb mixture evenly over the casserole. You want every bite to have that crunchy goodness!
- Now, pop it into the oven and bake for about 30-35 minutes. You’ll know it’s ready when the top is golden brown and bubbly. The aroma will drive you wild!
Let it cool for a few moments before serving, and then dig in—you’re going to love it!

Tips for Success
Alright, let’s make sure your French Onion Broccoli Cheese Casserole turns out absolutely perfect! First off, don’t skip greasing your baking dish; it helps avoid any sticky situations when serving. I always use a generous amount of cooking spray or butter—trust me, it’s worth it!
Also, when mixing the broccoli with the soup and cheeses, make sure everything is evenly coated. You don’t want any sad, dry broccoli hiding in there! And if you love a good crunch, consider toasting the breadcrumbs in a pan with a bit of olive oil before sprinkling them on top. It adds an extra layer of flavor and crispiness that’s just heavenly!
Lastly, be sure to keep an eye on the baking time. Ovens can be sneaky! If you notice the top getting too brown before the casserole is bubbling, just cover it loosely with foil to prevent burning. Enjoy the process, and happy cooking!
