I totally realize that a lot of people are falling off of the New Year’s Diet Resolution band wagon, but I am so hopeful that this roasted cauliflower recipe is going to help keep you motivated on that low carb diet of yours.

This recipe…woo. It does not taste like diet food, I can tell you that.

Then again, it’s not too often that keto recipes taste diet-y, which is probably why I love the keto diet so very, very much. It’s near and dear to my heart for three reasons – 1. Bacon, 2. Cheese, 3. Bacon and Cheese.

This keto mac and cheese is a family favorite.

Honestly, it’s not too often that my family dislikes one of my low carb recipes, which really makes following the diet a whole heck of a lot easier! That’s not always true with other diets I’ve tried.

I teamed up with Roth Cheese to bring you this cheesy cauliflower bake and I think you’re going to love the mix of Grand Cru and Havarti cheese.

If you haven’t tried Grand Cru before, it’s Roth’s signature alpine-style cheese. If you love Gruyere, you’ll love this cheese. And who doesn’t love Gruyere, especially in a mac and cheese?

Their Havarti is extra creamy and I have a really hard time not slicing it and serving it on a cheese board, but it’s really fantastic in a cheese sauce.

This low carb cheese sauce skips the traditional roux, since flour is full of carbs. Instead, you’ll just heat some heavy cream and stir in your grated cheese until everything is smooth and creamy. Sam approach as you’d take for homemade alfredo sauce!

I always add a bit of ground mustard powder to my cheese sauce for an extra boost of flavor, but if you don’t have it on hand, it’s fine to skip it. Ground nutmeg works well too.

I really love how easy this keto mac and cheese recipe is and you can totally just stop right there and call it a day.

However, I thought I’d take it a step further and add a garlic bread topping. I love crunchy toppings on baked mac and cheese, don’t you?

The topping is made of almond meal, butter, and garlic powder. So simple!
