What Is Cauliflower Mac and Cheese?

Cauliflower Mac and Cheese is the low-carb version of the classic comfort dish that traditionally uses pasta. In this case, tender cauliflower florets take the stage, swapping out the macaroni and keeping the carb count low. A must-try for anyone on a ketogenic diet or simply trying to cut down on carbs.

I know, I really do know that cauliflower IS NOT macaroni, nor potatoes, nor rice, but it’s a really good substitute for all those things. Have you tried my Loaded Mashed Cauliflower? Or my Chicken and Cauliflower Rice? DO it! You’ll see that cauliflower can save the day for those trying to cut down on carbs.

Why You’ll Love This Keto Mac & Cheese Recipe

  • This Keto Mac and Cheese recipe uses cauliflower as a fantastic stand-in for traditional macaroni.
  • Despite its healthier twist, it still captures the creamy, cheesy essence of classic Mac and Cheese.
  • Don’t just limit yourself to trying it on keto! This Cauliflower Mac and Cheese recipe is a flavorful low-carb dinner that can stand on its own as a main dish or pair wonderfully with Roast Chicken or Pulled Pork.

Recipe Ingredients

  • Cauliflower: The process of creating this low-carb delight involves simmering cauliflower florets until they’re tender.
  • For the cheese sauce: You’ll need milk, cream cheese, shredded cheeses, and a blend of spices.
  • Bacon: Once baked, you’ll top the casserole with crispy bacon for an added layer of indulgence!

How To Make Keto Mac and Cheese

Keto Mac and Cheese is perfect for anyone with a macaroni-cheese craving that can’t eat real pasta. But tender cauliflower, crispy bacon, and a super creamy cheese sauce can help. Hear me out: ?

  1. Add cauliflower florets to boiling water; cook, covered, for about 8 minutes or until tender. Drain and set aside.
  2. Add milk and softened cream cheese to a saucepan – gently whisk until the cream cheese is completely melted. I use the same saucepan, or pot, for boiling the cauliflower and for making the sauce.
  3. Stir in some garlic powder, chili powder, dried herbs, salt, and pepper, and whisk in the shredded cheddar cheese and shredded mozzarella cheese. Once the sauce is smooth, stir in the drained cauliflower.
  4. Transfer the cauliflower to a 9×13 baking dish and bake, uncovered, for about 18 to 20 minutes or until hot and bubbly. I also like to add a topping of pork rind panko crumbs for a nice crunch. 
  5. While that bakes, dice up few slices of bacon and fry until crispy.
  6. Remove casserole from oven, top with prepared bacon, and serve. 

Richly flavored and utterly delicious, Cauliflower Mac and Cheese is thick and creamy without any use of flour, so it’s also gluten-free! Basically, I’m trying to say not to swear off comfort food just because of a diet. ? 

Tips And Substitutions

  • Tenderness of Cauliflower: Be mindful not to overcook your cauliflower, as it can become mushy. Aim for a tender yet firm texture to replicate the bite of traditional macaroni.
  • Creamy Sauce Consistency: To avoid a grainy cheese sauce, add the cheese in gradually and whisk until completely melted before adding more.
  • Cheeses: Make sure that the cream cheese you are using is softened. If it isn’t, it will curdle. For those seeking variety, you can substitute the cheeses in the recipe with others like Gruyere, Gouda, or Monterey Jack, provided they are shredded for easy melting.
  • Spice Blend: If you don’t want to use the spices and seasonings that I use, go ahead and add whatever herbs and spices you like.
  • Toppings: Feel free to play around with the toppings. While the recipe calls for crispy bacon, you could also use sautéed onions, chives, or even extra cheese.

Is Cheese Keto-Friendly?

YES! Thank goodness. But always remember this; “in moderation.” Yes, cheese is totally acceptable on a low-carb and Keto diet, but don’t add it to every meal. Cheese still has calories, and too much cheese equals too many calories, which will not help with losing weight.
