Sometimes the best recipes are right under your nose. Like me, you probably have some tried and true favorites: simple things that you make frequently but never think are special because they are just part of your normal family fabric.
This Baked Cauliflower “Mac” and Cheese Casserole is exactly that kind of recipe. I make it almost weekly, and it never actually dawned on me that my readers would actually enjoy it too. Not sure what I was thinking, or not thinking.
Like I mentioned, we eat this one quite a bit. There is nothing more satisfying than a perfectly cooked ribeye steak and a heaping helping of this Cauliflower "Mac" and Cheese recipe. The cheese sauce is nice and thick, and is perfect for dipping my steak in. This recipe reminds me of something you’d get a fancy steakhouse, or a really solid BBQ joint.
This is comfort food, pure and simple. The recipe is straightforward and easy to whip up on a weeknight. I really have no idea why I haven’t shared it until now. It’s one of our favorites, and I hope you enjoy it as much as we do.

Low Carb “Mac” and Cheese Recipe Tips & Tricks
Switch up the cheese to create new flavor combinations. Honestly, I use whatever shredded cheese that I have in the house, but a combination of cheese always works best. Just make sure you are using a good melting cheese. There are certain things that just won’t work here. Hard cheese or very soft can be a bit tricky. I find that gruyere, cheddar, pepper jack, shredded Mexican cheese blends, gouda, havarti, or Kerrygold Dubliner are super tasty in this dish.
Add protein to make a full meal. I absolutely love throwing in some extra protein to make this a full meal. We love it with leftover ham, cooked bacon, or even shredded pork. Come to think of it, chicken or beef would be great too. There’s very little that would not work well here. Feel free to experiment!
How to Serve and Store Cauliflower "Mac and Cheese"
This is the kind of decadent comfort food that needs a killer main dish to serve alongside. I highly recommend a nice grilled steak, ribs, or even a Low Carb Meatloaf.
If you have leftovers, and I highly doubt you will, store any remaining baked cheesy cauliflower in an airtight container in the fridge for 2-3 days. You can reheat this in the microwave or in the oven at low temperature.
This dish can be made ahead. Store in the refrigerator until ready to bake. I would not leave this overnight, but it could be made in the morning and then baked at night for dinner.

Overall we LOVE this recipe. I make it all the time. My question is: everyone once in a while the cheeses seem to separate giving an oily, gritty texture, not the creamy texture that I usually get. What could I be doing wrong?

Hi Vickie, thank you for the compliment! To be honest, that actually happens to me too. I think it either might be the type of cheese I use (I often just throw in whatever is in the fridge at the time), or if I use a lower fat % heavy cream. Normally, I try to buy 36% or higher. Higher fat percentage is much richer, so the sauce requires very little cooking to thicken. Hope that helps! Thank you again for trying my recipe and for your comment.
