It was my son’s birthday and he wanted homemade mac and cheese. But, following a lazy keto diet, I didn’t want to eat the pasta. So, I made up a big batch of this keto-ized cheese sauce, smothered cauliflower with it, and baked it in the oven until it was brown and bubbly and OMIGOSH so darn good!

For the kids, they got theirs with noodles, so this Keto Cauliflower No-Mac ‘n Cheese was a win-win for the whole family! You can also serve it with Zucchini Spaghetti if you’re looking for a noodley texture.

Traditional cheese sauces have flour in them to help thicken the sauce and bind it all together. But for this cheesy creation, I used all cream cheese, heavy cream, and plenty of tasty cheese. No flour, no thickeners, no carbs, just a magical combination of goodness that turns this into a tasty dish.

Keto Cauliflower No-Mac ‘n Cheese Variations

You need to stick with the cream cheese and cream base, but you can switch up the flavors of this cheese sauce pretty darn easily. I used green onions, bacon, and a 3-cheese Italian blend. But, cheddar, ham, Swiss, heck even blue cheese, would all go great. As long as it is a good melting cheese, it’ll work.

You could also smother this velvety sauce over broccoli, chicken, or whatever you’ve got a taste for. And, it comes together quickly and you can pop any leftovers into the fridge for a quick weeknight meal. Bake your no-mac ‘n cheese in cute individual lidded ramekins for an attractive presentation.

What to Serve with Cauliflower No-Mac ‘n Cheese

Ham is my favorite meat with this cheesy goodness. There’s something about the combination of ham and cheese. But, I also love grilled meats with this dish, like these Lemon-Oregano Chicken Kabobs. Another great pick is a simple, Bacon-Wrapped Pork Tenderloin. MmmMmm!

  • 1 each head of cauliflower
  • 1/2 block cream cheese 4 oz
  • 1 cup heavy cream
  • 1 clove garlic minced
  • 1 tsp mustard powder
  • 2 cups shredded Italian blend cheese
  • 4 slices bacon cooked crisp and drained
  • 1/2 cup green onions sliced


  • To make the sauce, add the cream cheese and cream to a pot and warm it slowly, stirring frequently, over low heat. When combined, add the mustard powder and garlic. Remove from the heat and stir in the shredded cheese blend, crisp-cooked bacon, and green onions. Set aside.
  • Prepare the cauliflower by breaking the head into bite-size florets, cutting them in quarters if necessary. Remove excess stems. Rinse and shake to dry.
  • Put the cauliflower into a large bowl and add about half the cheese sauce. Stir well to combine. You want it saucy but not drowning in sauce, so add more if needed. 
  • Put the cheesy cauliflower into a baking dish or individual ramekins and bake in a 375-F oven for about 20 minutes. Individual size dishes will require much less cooking time, maybe 8-10 minutes, so check frequently. You want the top to be bubbly and brown and the cauliflower tender-crisp.
