This Healthy Cauliflower and Broccoli Casserole is just 79 calories and has just 6 ingredients! Plus I have supplied you with 5 flavors total. So you can make the casserole 5 different ways, even with my famous Ranch Seasoning Mix!
This hearty side dish is great with any protein main dish you make. It’s especially great with roasted chicken though. I love to make it for holidays too, it’s a healthy dish and I love that I can have seconds and thirds without guilt.
The original recipe calls for whole grain mustard and provolone (it’s heavenly!) but if you don’t like either, you can use your favorite cheese and you can swap out the mustard for the 4 additional options I have supplied below.

How to Make Healthy Cauliflower and Broccoli Casserole
I like microwave the cauliflower ahead of time to soften it up. But if you don’t have or don’t like to use a microwave, you can easily steam the cauliflower. Or just roast it for 20 minutes before tossing in the dressing and combining it with the rest of the veggies.
How to Make Healthy Broccoli and Cauliflower Casserole:
- Preheat oven to 375 degrees, and spray a 9×13 baking dish with olive oil.
- To a large bowl combine the mustard and 1/4 cup water and mix together.
- Add the cauliflower and 1/2 cup water to a microwave safe bowl and microwave for 5 minutes until tender.
- Carefully remove and drain, then add the cauliflower, broccoli, and onions to the mustard and toss well to combine.
- Pour the veggies into the prepared baking dish, scraping any leftover mustard over the top.
- Add the provolone cheese to the top, spreading out so you get melted cheese over the entire top, and spray with olive oil.
- Add to the oven and bake for 20 minutes, then broil for 1-3 minutes (watch closely) until the cheese is melted.
- Serve hot.
