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 that can turn those who don’t love vegetables into people who are asking for seconds.

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

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

To make this dish, you are going to cook the cauliflower in boiling salted water, then pour a cheese sauce over the top.

  • 1 teaspoons salt
  • 2 tablespoons butter
  • 2 tablespoons flour
  • 1 cup milk
  • 1/4 teaspoon dry yellow mustard
  • 8 ounces Cheddar cheese divided use

Instructions

  • Preheat oven to 350 degrees. Cook cauliflower in a large pot of salted water. The cauliflower should be tender, but firm. The cooking time should be 5 to 6 minutes. 
  • While the cauliflower is cooking, start the cheese sauce. Melt two tablespoons of butter in a small saucepan. When the butter has melted completely add the flour. Cook flour for 1 to 2 minutes. Slowly begin to add milk, which each addition of milk the sauce should thicken. Add in the dry yellow mustard and stir in to combine. When all of the milk is added add 4 ounces of cheese. Stir in the cheese until it melts completely. 
  • Place cooked cauliflower into a large casserole dish. Pour cheese sauce over the cauliflower. Sprinkle remaining 4 ounces of cheese over the cauliflower. Place the cauliflower into the oven and bake for another 15 minutes. When the cheese should begin to brown slightly the gratin is done.

    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.
