Cheesy Cauliflower Bake

I don’t know what is it about cauliflower. Even if you live with a household of people that are not in love with vegetables, this one can turn those who don’t love vegetables into people who are asking for seconds.

This baked cauliflower with cheese sauce is a great side dish to make any time. You can make it ahead of time and serve it whenever you like. Not all side dishes reheat as well as this one does.

What Makes This Dish Special

A touch of dry mustard powder adds just the right amount of zip and zing to this classic side dish. Cheddar cheese sauce needs a touch of heat to make it just right.

I know you are going to love this way to prepare cauliflower.

You can buy cauliflower whole from the grocery store, or you can purchase bags of cauliflower that has already been cut up.

If you want to make this keto-friendly, leave out the flour and substitute heavy cream for the milk.

    This looks great! Could I use frozen cauliflower in this recipe? Would I change anything if I used frozen?
    Thank you!

    I have never tried a dish like this but I know I would love it! Cauliflower really is a crowd pleaser veggie, isn’t it? 🙂 Yum! Pinning for later!

    This looks great! It’s like mac and cheese in a healthy way! My kids would love this too. I love cauliflower and with cheese, my kids will too ! Thanks !

    Cauliflower is such a fabulous vegetable! We add dry mustard to most of our cheesy dishes, but I’ve never made this. Our weekly menu has mac and cheese slated for Tuesday, but I think I can swap out the noodles for cauliflower and top with some crumbled bacon. YUM!

    What a terrific and healthier alternative to other potato side-dishes (such as Potatoes Au Gratin, or Scalloped Potatoes). This sounds SO delicious, and I definitely serve this as one of my sides- the next time I make a baked ham dinner. Thanks for your lovely recipes, Stephanie.
