You want to know how to get your kids to eat the vegetables? Start with this loaded casserole! Beyond the cheese, beyond the sour cream and look past the fried onions, it’s nothing but vegetables! Anyway I can get those kids to eat vegetables is a win in my book. They loved this Broccoli Cauliflower Casserole so it’s going on my regular side dish rotation!
And your whole family will love it!
This has been a great side dish and I’ve served it at more family gatherings and it’s so popular on the buffet!
It’s one of my favorite meals for the holidays because it’s easy to make and can be made ahead a day or two, covered with foil and tucked into the refrigerator until you’re ready to heat it up. Pair it with my easy Crock Pot Turkey Breast and everyone will love it!
Easy, cheesy, delicious!
Ingredients for Broccoli Cauliflower Casserole
- Frozen Vegetables – Broccoli Florets and Cauliflower Florets
- Cream of mushroom soup
- Sour cream
- Sharp cheddar cheese
- French fried onions
Steps to Make!
- Prep – Preheat the oven. Grease the baking dish and set aside.
- Mix – In a saucepan combine the soup, sour cream, cheese and fried onions. Stir over medium heat until blended. Add broccoli and cauliflower and continue stirring until combined.
- Bake – Transfer to the prepared baking dish. Place in preheated oven and bake 25-30 minutes, uncovered. Top with remaining cheese and onions and place back in oven until cheese melts.
Expert Tips
- When it comes to baking a casserole, glass or pyrex is your best choice. Both glass and pyrex take longer to heat up, but conduct heat well and get super hot. An oven-safe dish is a must. Another must? Dishwasher safe for easy clean-up!
- If you would like to want to use fresh vegetables you can but you would need to steam or roast them first. This is the perfect time to take a shortcut and use frozen vegetables. This is a terrific pantry-staple side dish!
- I recommend sharp cheddar cheese. It gives a tanginess to the recipe that makes it a real winner! Though you can certainly substitute with Monterey Jack or Provolone Cheese. If you do use a milder cheese a handful of Parmesan will add the sharp saltiness of the cheddar.
- Grab a block of cheese and grate it yourself because it will melt better! Pre-Shredded cheese has additives that hinder it from melting.
See that cheesy goodness? I don’t know what you’ll love more: the cheesiness of this casserole or the crunchy onions when all of this bakes up to golden, bubbly deliciousness! Mmmm!!!!

Tried this recipe?Let us know how it was!
The instructions say 11/4 cup onions in the dish and more on top. But the list of ingredients says 6 oz.
You place 1 1/4 c. in the dish then the rest you put on top of it as stated in step 3. Hope that helps Judy!
Merry Christmas!!
If I am doubling, do I need to double the time needed to bake it? Thanks in advance!
You probably won’t need to double the time, I would say 30-45 minutes will do it!
Thanks for the reply! I made it a couple of days ago and baked it for about 45 minutes and it came out amazing!! Thank you so much for sharing this recipe. It is soo good~
You’re welcome!! I’m so glad you enjoyed it!
This is a staple for my holiday recipes. A good tip for others, it tastes even better the next day so I plan on making it this evening. Going to try just cauliflower and throwing bacon in there.
I’m so glad you enjoy this one! Thanks for the tip, Emma!
Can you make this in a crock pot?
I think it would work! It may take a while for the veggies to cook all the way through so you might want to do a full 6-8 hours on low.
Just made this tonight. I add Sautéed chicken and mushrooms . Came out great!!!! Went to take a picture but it was all gone !!! Lol
Awesome! So glad you enjoyed it!
Oooo that’s like a whole meal! I’m making this as a side for my Christmas Eve dinner!
I hope you all enjoy it!
Ive made this for years, but have always used swiss cheese. Its the most requested dish at any family gathering.
Sounds lovely! Glad everyone enjoys it!
Delish! My daughter and I went back for seconds! Only thing I add was a little pepper 🙂
Excellent! Glad you and your daughter enjoyed it!
So simple, so sublime. I used yogurt instead of sour cream, and don’t regret my decision. Went great with plan-fried chicken thighs. Thanks for the recipe!
You’re welcome! So glad you enjoyed it!
Are you aware of any low sodium French Fried Onions? I only see the one typical brand at the markets around me, and only one type.
I’m sorry I’m not aware of any lower sodium options. You could maybe try an online search!
Hi Julie,
You are doing a wunnerful job…..(as my kids say), but I would like to use fresh veggies instead. Should I just add to cooking time ?
Stay well….I look forward to seeing things from you…
~ Anne Marie ~
Thanks Anne Marie! You will probably want to boil them both first until they are crisp tender and then transfer them to the baking dish and finish out the recipe. You shouldn’t need extra time baking then. I hope you love it!
Julie – thank you for sharing your recipes and tips. I hope during these challenging times you and your family are safe and well.
Blessings
Carla
Thanks Carla! We are doing well, a little stir-crazy, but healthy and safe!
very easy recipe ty for providing it
You’re welcome!
Do you bake it and then refrigerate?
No, I would refrigerate once it’s poured into the baking dish if you are making it ahead. Pull it out of the fridge and continue with the instructions. It may need a few more minutes to cook after being refrigerated.
can I use a different soup beside Cream of Mushroom?
You can use any cream of soup. Like cream of chicken, cream of onion etc.
I’m making this ahead for Christmas! Thank you for a wonderful & easy recipe!
