Cauliflower Mac And Cheese

Reviews

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:

  1. The cauliflower adds a savory flavor that complements the cheese, without getting lost in it.
  2. 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.

Is Cauliflower Mac and Cheese Keto? Low Carb?

This baked cauliflower mac and cheese is the PERFECT pasta substitute for traditional mac and cheese, with a fraction of the carbs and an added dose of veggies.

My #1 reason for loving this recipe? There are 43 g carbs in mac and cheese per serving. In this recipe? There are 6g. Even if you aren’t a low carb eater, you know that’s pretty cool…

How to Make Cauliflower Mac and Cheese

Baked cauliflower mac n cheese is surprisingly easy to make. Here’s how with some pictures to guide you:

Prep your “macaroni” by tossing cauliflower in oil and seasoning and baking it in the oven. Roasted cauliflower takes about 25 minutes.

Make the sauce. Melt the butter along with your heavy cream. Stir in the cheddar.

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:

  1. 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.
  2. Or, skip the meat. 
  3. 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.
  4. 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.

  5. looks great – not only a side, but a meal in it’s self with a salad on the side. i do have a question — can frozen cauliflower be used? if so, how much and how to???

    happy new year.

    • Hi Barbara! Happy New Year ? You can definitely use frozen cauliflower, although the texture would change a bit (the “noodles” will be a bit softer). Try using 10-12 ounces. Hope you enjoy!
