If you’re looking for a low carb keto mac and cheese replacement, you may be surprised by this cauliflower mac and cheese recipe! Like many keto cauliflower recipes, this dish takes on the flavors of the sauce. It’s almost like the real thing, and so much healthier. Yes, I know it’s not actual pasta, but it will totally fulfill that comfort food craving — but if you want real noodles, you can pour the same sauce over keto pasta noodles or other low carb pasta alternatives instead. Growing up in a Russian-speaking family, I didn’t get to try all-American macaroni and cheese until much later. I still remember tasting it for the first time, not knowing (or caring!) about how processed it was. The carbs in mac and cheese didn’t even cross my mind. I missed this dish dearly when I switched to a low carb lifestyle, and came up with this keto mac and cheese version to fulfill that need.
What Is Cauliflower Mac N Cheese?
Keto cauliflower mac and cheese tastes like all the cheesy goodness of macaroni and cheese, but using cauliflower florets instead of macaroni and the same type of rich cheese sauce as the original. Even if you’re a die-hard pasta lover, I think you’ll love the flavors in this dish. Roasted cauliflower makes a great stand-in for macaroni on the keto diet — hence the name. It’s delicious as a keto side dish or vegetarian keto main dish.
Ingredients You’ll Need
This section explains how to choose the best ingredients for low carb mac and cheese, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
For The Cauliflower:
Cauliflower – Fresh cauliflower works best for this recipe, but you can also use frozen and increase the cooking time when you roast it. Be sure the florets are very small — getting more pieces in every bite helps make this keto mac and cheese more reminiscent of the real thing.Olive Oil – For roasting the cauliflower. Avocado is also fine to use. In an earlier version of this recipe (including the YouTube video), I simply used melted butter (which is also used in the cheese sauce) to reduce the total number of ingredients. Feel free to do this if you like. Butter is not normally recommended for roasting due to the high temperature, but I found it works fine for roasting small cauliflower florets.Salt & Pepper
For The Cheese Sauce:
Shredded Sharp Cheddar Cheese – You can swap this cheese with any keto cheese you prefer that melts easily, such as gruyere, gouda, or mozzarella cheese. Hard cheeses, such as parmesan cheese, will not make as smooth a sauce.Heavy Cream – Makes a rich and smooth sauce. Some people also stir cream cheese into the sauce, but I don’t find it necessary and it tastes less authentic that way.Unsweetened Almond Milk – You can also use coconut milk beverage from the carton or more heavy cream for a nut-free version.Butter – For flavor. Use unsalted.
I love this sauce so much that I wrote a post dedicated to this keto cheese sauce recipe. In addition to keto cauliflower mac and cheese, it’s delicious for topping or dipping fresh or roasted broccoli.

What To Serve With Keto Cauliflower Mac And Cheese
I love to serve this cauliflower mac and cheese recipe with a simple protein to turn it into a whole meal. Here are a few keto main dish recipes for you to choose from: For more complex flavors, add spices like garlic powder, onion powder, smoked paprika, or your favorite spice mixes. You can also add seasonings directly to the cheese sauce. However, if you find that the sauce is not thick enough, you can simply add more shredded cheese to the sauce before tossing with the cauliflower. If it’s too thick, you can thin out with more almond milk or cream.
Chicken – Try keto mac and cheese with garlic butter chicken, crispy baked drumsticks, garlic chicken thighs, or baked buffalo chicken.Turkey – Enjoy a homesyle meal with turkey meatloaf, slow cooker turkey breast, or keto turkey burgers.Fish – Serve lighter fare with pan seared halibut, baked tilapia, or grilled shrimp skewers.Bacon – The best match for stirring into cauliflower and cheese!
