Cheesy Baked Cauliflower

Cauliflower is an excellent vegetable that is hearty and one that most everyone loves. I have been taking classes to become a chef this spring. Gratins are a dish that we make a lot of.

I wanted to update a classic French dish and make it with just a bit of spice. Pepper Jack cheese adds just a little bit of heat with the peppers that are in the cheese.

If you do not like Pepper Jack cheese you could use cheddar or Swiss cheese as either will work very well.

I like to make this baked cauliflower gratin and serve it with a roast. I also use it as a side dish with chicken, pork, turkey, or ham. I think it holds up well to a hearty meat dish.

Cauliflower au Gratin is low carb and keto friendly.

    Just made it for Sunday dinner to go along with my roasted chicken. I substituted cheese because I did not have pepper jack. I used shredded gouda. Still delicious. Cant wait to make with pepper jack next time. Thank you for recipe

  2. Jaime

    So delicious! I made this for Christmas Eve — it was a huge hit! I used FairLife Fat Free milk. I tried to go healthier yet by using coconut oil — DON’T DO IT! I had a palm-to-face moment with that…lol

  3. Charlene

    It looks delicious when baked in the over. I have honestly never thought of that as I always just mix mine and serve it in a bowl. I like your idea much more. I also like to add pepper flakes for some zip

  4. Rose

    There are only two of us, so I would prefer using frozen cauliflower. How much do you think I would need? Also, would you defrost the cauliflower and then coninue with the recipe as written? Thank you for your help.

    I cubed smoked gouda and used instead. Placed under the broiler at the end. Very good! Can microwave cauliflower in a glass dish if in a hurry.

  6. Nancy Faye

    This is similar to a recipe my family used to love. It was mayonnaise and mustard mixed together spread over the top of precooked cauliflower and then topped with cheddar cheese. Warm under the broiler until cheese melts. My kids couldn’t get enough of it. I think it was in one of the Better Homes and Garden Cookbooks.

  7. Geri

    I’m going to make this and add a few broccoli florets for the green and some chopped red pepper for the red to give it some Christmas color on the table!

  8. Katie

    Made this today. Totally delicious! The husband said its a “keeper”. The only thing I did different was to put it under the broiler for a couple of minutes at the end since it wasn’t browning enough in bake mode. The brown parts from the broiler ended up being the icing on the gratin lol. Thank you.
