We are not big broccoli fans, but we both LOVED this French Onion Broccoli Cheese Casserole. It is definitely our favorite broccoli casserole. With only 5 simple ingredients, this can’t be beaten!!! PLUS it is ready to eat in about 30 minutes. We love quick and easy side dish recipes like this.
How To Make French Onion Broccoli Cheese Casserole
This is hands-down our favorite broccoli casserole. It is super delicious and SUPER easy to make with only 5 simple ingredients. Broccoli, cream of mushroom soup, french onion dip, cheddar cheese, and french fried onions. I used fresh broccoli florets, but you could also use frozen broccoli florets.
To make this broccoli casserole, simply mix everything together and bake. It literally takes about 5 minutes to assemble.
One very important note about this French Onion Broccoli Cheese Casserole. This recipe uses a cup of French onion dip. You want to use the sour cream based French onion dip found in the refrigerated section at the grocery store. I prefer the flavor of Kraft brand, but Heluva Good Dip, Barbers, Dean’s or the store brand will work great too! Just make sure it is sour cream based and not the jarred stuff in the chip aisle. SO important!!
Can I Make Broccoli Casserole in Advance and Freeze?
Absolutely! You can assemble it ahead of time and refrigerate it until ready to eat. You can also make this casserole ahead of time and freeze it for later. If baking from frozen, let the casserole thaw completely in the refrigerator and then bake as below. You can also freeze the leftovers for a quick side dish later. Just thaw and reheat in the microwave.

Notes:

This was amazing! My husband doesn’t like onions and he raved about this dish. I will be making this often, so glad I found this recipe. I didn’t see any mention in the recipe about cooking the broccoli first, but I did steam my broccoli before I mixed it with all the ingredients.
And I also added rotisserie chicken! I served it the first night with a salad, and the second night with beets. Comfort food!
Delicious. And easy. This recipe is so easy to tweek. I didn’t have the onion dip so I subbed with sour cream, a little onion soup mix and some dried minced onion. I also added a bit of heavy cream (no more than a quarter cup). And I used GV Fiesta shredded cheese and cream of chicken soup. Here’s the point: It’s a very forgiving recipe, and it’s delicious. The cannister of French Fried Onions, however, is a must!!! I love this recipe!!!
This was sooooo good I added ham to mine..this is definitely a keep recipe
This looks delicious have you added rice to this at all?
I’ve never tried this with rice added.
Does the fresh brocoli release water while cooking? I had to eyeball the amount of broccoli cut up because the bagged broccoli was sold out. I feel like it looks a little dry and wondering if I should add more dip and soup.
It isn’t watery.
If I use frozen broccoli florets, do I cook them before adding to the casserole?
I didn’t cook the fresh broccoli prior to adding it to the casserole, so I wouldn’t think so. It just depends on how soft you like your broccoli.
so good, made it for women’s ministry potluck and they cleaned it out good. nothing left. easy to make and a good way to use up onion dip when you run out of chips. I will definitely make it again.
This is delicious and easy to make! I made it at Christmas, and the family raved about it. I just made it again tonight, I added the breasts of a rotisserie chicken to it. IT IS AMAZING. The chicken added some protein and made it a 1 pan meal for the family!
I added chicken also but forgot to post that in my comment. It is super delicious.
What do you think about adding French onion dried soup mix instead of dip?
I wouldn’t, but you can make this however you want.
