Ingredients

  • Cauliflower: Cauliflower is super nutritious whilst being low in carbohydrates, sodium, and calories. It’s also fat-free and cholesterol-free. It’s a great source of vitamins C and K.
  • Salt and pepper: Added to taste.
  • Garlic: Freshly minced garlic adds a really great flavor to the mashed cauliflower.
  • Sour cream: To create a creamy texture. I prefer to use full-fat, but you can use low-fat. You could also use Greek yogurt instead.
  • Butter: You can use salted or unsalted butter, just adjust the amount of added salt to suit your taste. You could also use extra virgin olive oil instead of butter.
  • Fresh herbs and seasonings: Chives. You could also add some chopped fresh thyme but that is optional.

Can you make it vegan?

As it stands, this recipe is vegetarian, but it does contain dairy. To make this mashed garlic cauliflower plant-based and dairy-free, simply use vegan butter and sour cream.

Can you use fresh or frozen cauliflower?

Either work in this recipe, you just need to boil frozen cauliflower for a couple of minutes longer. Use about 3 to 4 cups or 2 pounds of frozen cauliflower for this recipe.

Can you make it ahead of time?

Yes! Once you have made your mashed cauliflower, let it cool and then transfer it to an airtight container. It will keep well in the fridge for 3 to 4 days. You can then gently reheat it on the stovetop or for a minute or two in the microwave.

Can you freeze it?

Yes, this keto cauliflower mash is a freezer-friendly side dish, but if you plan on freezing it, it’s best not to add in the sour cream as this can separate. Place the mash into a freezer bag and squeeze out as much air as possible. It will keep well for up to 6 months.

Thaw the frozen cauliflower in the fridge, reheat it on the stovetop, and stir in the sour cream.
