I am a super big broccoli and cauliflower fan. My favorite soup to make is our CopyCat Panera Broccoli Cheddar Soup. I will quite often purchase the store bought veggie steamer bags for a quick side dish with our meals.

If we are having a nice holiday dinner, I like to make an easy casserole. I made this broccoli and cauliflower casserole last Thanksgiving and it was a hit. I am looking forward to making it again this year for Christmas dinner.
Nothing beats the combo of broccoli and cheese or cauliflower and cheese except both of them in one cheesy and creamy casserole. Then add on a bread crumb topping for a bit of crunch. YUMMY!
I used fresh broccoli and a head of fresh cauliflower. If you are in a pinch for time, frozen would work fine too! I also like to use sharp cheddar to cut down on the grease. You could also use a pepper jack or mild cheddar. You could prep the dish the night before and just toss it in the oven before dinner. PERFECT!

This is my first comment ever!!! That’s how impressed I am with this recipe!! It was soooooo delicious!! Dirtied quite a few pots and pans but well worth it especially when your husband does the dishes!! I’ll be making those a lot! Thank you!!
Omg this was so good! I’ve been looking for ways to incorporate a bigger variety or veggies into mine and my hubbies dinners and this is a keeper! I added brownes ground turkey to make it more of a entire meal within itself amd used wheat flour as a substitute. We kept saying how good it was while eating. Thanks so much for sharing!
I made this recipe for my Christmas dinner this year.
I did changed your recipe slightly though.
For a 9″X13″ casserole dish… I added 2 extra broccoli bunches, make 1 1/2 X the sauce & grated cheddar and I added 3 processed cheese slices (I love cheese) to the sauce. It was super delicious and everyone there was wanting the recipe, even my husband raved about it!
Thank you so much for a wonderful recipe. I will be definitely be making this recipe for every occasion!?
I️ made this for Thanksgiving and it was the biggest hit there! I’ve been getting phone all after phone call for the recipe. I️ used a tin pan and doubled the bread crumbs to cover the top. This will definitely be added to the holiday food list! Thank you ??
Could you make this in the crockpot?
Hey There–
What is the size of the casserole dish–more like an 8X8? I’m wondering if I need to double this for Thanksgiving! :)
