Pesto Keto Cauliflower Mashed “Potatoes”

Mashed potatoes are a staple for holiday dinners, and they are one of the most beloved comfort food side dishes out there. Mashed potatoes also have tons of carbs, so they’re a big no-no on the keto diet.

I’m not a huge cauliflower fan, but if prepared right, it makes an amazing low-carb potato substitute!

When shopping for pesto, be sure to check the label to make sure that the brand you pick is keto-friendly (no emulsifiers, etc).

Regular dairy milk contains a fair amount of sugar, so almond milk is a more keto-friendly alternative. It’s also perfect for those of you (like me) that need to avoid lactose.

How to make keto mashed potatoes with cauliflower

Add your pesto, almond milk, and butter slowly. Taste-test as you go until you’ve got just the right amount of flavor – you might like more or less pesto than we do.
