Instructions

Here’s how to make this delicious broccoli casserole. You can find the full ingredients list along with instructions in the recipe card below.

Preheat the oven to 350°

First, steam the broccoli and add it to a large bowl. Add the low sodium cream of mushroom soup, Heluva Good French onion dip and hand shredded cheese. Season it with salt and pepper and mix everything together until it’s evenly combined.

NOTE- The cheese, cream of mushroom soup and French onion dip will all add salt to the dish so only add extra if needed.

NOTE- Feel free to chop the broccoli up a little to create a smoother texture

Now, add the mixture to a 9 x 9” greased baking dish and smooth it out so that it’s flat and even. Place it into the center rack of the oven, uncovered, for 25 minutes.

NOTE: Placing it into the center rack of the oven will let the air to circulate around it and cook evenly.

Then, carefully remove the casserole from the oven and top it with more cheese and the crispy fried onions. Place it back into the oven for another 5 minutes.

NOTE- Be sure to shred the cheddar cheese yourself and avoid the pre shredded stuff that comes in a bag. It will melt much better that way.

Finally, let the casserole rest for 5-10 minutes before serving and enjoy!

PRO TIP- Letting the casserole rest will allow it to thinking up and set before serving so it won’t be a runny mess.
