Cauliflower mac and cheese is here to redeem every piece of cauliflower that’s ever been left alone on a veggie tray. The humble cauliflower is a great pasta substitute and is loaded with vitamins and fiber. But personally, I’ve never craved cauliflower. Until now.

Why You’ll Love Baked Cauliflower Mac and Cheese

Cauliflower? A comfort food!? Stay with me… This is greater than your average smother-it-with-cheese situation for two reasons:

The cauliflower adds a savory flavor that complements the cheese, without getting lost in it.
The cheese sauce is luxuriously velvety, creamy, and cheesy.

Forget the veggie tray or been-there-mash, this is how I’ll be bringing cauliflower to the table this season.

Pro Tips

This isn’t your average cauliflower and cheese recipe. I’ve added a few surprises to keep you coming back for seconds. Here’s everything you need to know for how to make mac and cheese, the cauliflower way:

Prebake the cauliflower, this will get it soft enough to work well as a pasta dupe, and will mellow out its flavor so our baked cauliflower with cheese doesn’t taste too much like, well, vegetables.
Turn this into one pot mac and cheese by making your cheese sauce in the same pan. Toss your baked cauliflower in the cheese sauce, then bake it in the oven. One pan wonder!
Add a crunch to the top. As you know, most mac and cheese recipes are topped with breadcrumbs. In an effort to keep this recipe gluten free and low carb, I like adding crushed pork rinds, which add a delicious crunch (and a bit of bacon-y flavor). If pork rinds aren’t your thing, be sure to add crunch with breadcrumbs/gf breadcrumbs.

Can You Freeze Cauliflower Mac n Cheese?

As with most cheese or cream sauces, this baked cauliflower mac and cheese is best fresh, but you can freeze it if you must. I like to portion it into resealable baggies. Reheat leftovers in the oven or toaster oven to re-crisp the top.

Serving Recommendations

What goes well with mac and cheese?? All.The.Things. But the beauty of this dish is you really don’t have to serve it with anything. It’s great on its own. I like to dish it up alongside meat dishes. It’s also one of our family’s Thanksgiving staples.

Tweaks + Variations

As long as you get the basics for this cheesy cauliflower recipe down, you can switch and swap ingredients as you see fit. Here are some ideas that come to mind:

Add protein. Pancetta, bacon, cubed ham, heck even shredded chicken would be a delicious addition to this cauliflower mac and cheese. Be sure to cook any meat before adding it.
Or, skip the meat.
Add more vegetables. Broccoli is a natural complement, but everything tastes delicious in this cheese sauce. Try adding sauteed kale, red onions, mushrooms, or zucchini noodles.
Try a different type of “pasta” – again, broccoli is the obvious sub. Or, give my almond flour pasta, spaghetti squash, butternut squash noodles, or keto gnocchi a try! Skip shirataki noodles here, they work best as a stir-fry sub.
