This roasted cauliflower mac and cheese combines the creamy, cheesy flavor of mac and cheese with the extra nutrients in cauliflower – a delicious, nutritious meal the entire family loves!

What’s better than a cheesy pasta dish? like one-pot chili mac, taco pasta, chicken parmesan pasta, or even penne with olives, tomatoes, and goat cheese!

Roasted Cauliflower Mac and Cheese

Here is a mind-blowing combination: pasta, roasted cauliflower and garlic, and cheese. Then baked and I died. This roasted cauliflower mac and cheese is such an awesome hybrid of two dishes, is delicious and contains half of large cauliflower head. My kids had seconds, licked the plates and after my toddler told me “I like you”.

I already have a healthy mac and cheese, and spaghetti squash mac n cheese, so why not a cauli version?!

When you rice/finely chop cauliflower and mix with grains or other vegetables, it adds volume and lowers calories. Living proof in readers’ reviews of skillet cauliflower gratin and sesame cauliflower with bell peppers. Since then I’ve also shared recipes for cauliflower potato salad, a cauliflower pizza crust, cauliflower shepherd’s pie, and a long list of cauliflower rice recipes!

And please note that you don’t have to roast cauliflower separately beforehand unlike the name might suggest. It gets roasted during baking as a fully assembled casserole. I love making one-pot pasta dishes, like Instant Pot goulash, Instant Pot mac and cheese, and turkey tetrazzini!

You could also throw in some broccoli or peas. It freezes really well too. For milk, I have previously used 1% cow’s milk and unsweetened soy milk this time. Both tasted delicious. Any milk would work, just make sure it’s not flavoured or sweetened.

I like this cauliflower mac and cheese casserole best when it cools down a bit and cut into slices. Enjoy!
