You may have noticed I’m a big fan of making keto comfort food, and this recipe satisfies the mother of all comfort foods, Mac ‘n Cheese. But in this case, it’s Keto Cauliflower Mac ‘n Cheese!

Now, I’m not going to lie to you and say the magic of cauliflower will have you believing that you’re eating macaroni noodles. That’s asking a bit much of this white cruciferous plant.

But, if you are a cheese lover like I am…if your love of cheese is rivaled only by your love of chocolate, then you will love this recipe!

I’m including Keto Cauliflower Mac ‘n Cheese in my holiday food challenge, but truth be told, this recipe is great year-round.

How to Make Keto Cauliflower Mac ‘n Cheese for Your Holiday Gathering

 I used the leftover cauliflower florets from the “potato” casserole to make this dish. It’s super simple to make and only requires a few ingredients.

Start by heating your oven to 400 degrees F. Spread the cauliflower florets out in a greased 8×8 baking dish.

Drizzle olive oil over the cauliflower and season with salt and pepper to taste. Bake for 30 minutes until the cauliflower is fork-tender.

While the cauliflower is baking, prepare the cheese sauce. Make sure to keep about ½ cup of shredded cheddar to the side to top the casserole with.

Add heavy cream, cream cheese, shredded cheddar, and Dijon mustard to a medium saucepan and cook until everything is melted together, stirring occasionally. Salt and pepper to taste.

Pour the cheese sauce over the roasted cauliflower and sprinkle with the ½ cup of shredded cheese you set aside earlier.

Bake the keto mac ‘n cheese casserole for an additional 10 minutes, or until the cheese is melted and bubbly on top. I like to bump the oven up to broil for the last minute or two to get the cheese well done on top.

But be careful not to burn the casserole If you decide to do this.

I recommend allowing the casserole to cool slightly before serving. This dish heats up really well, so feel free to double or triple the recipe if you’d like to eat it for several meals!

Optional Additions

There are many ingredients you could add to this dish to make it even yummier.

Onions

Bacon (because I think we can all agree, bacon makes everything better!)
