I have always been a fan of adding cauliflower to recipes. From cauliflower gnocchi to cauliflower casserole to cauliflower hummus, the use of cauliflower enhances the flavors.

Which is definitely the case in this garlic mashed potatoes and cauliflower recipe. The cauliflower adds an element of sweetness that compliments the potatoes. The butter, milk and sautéed garlic top it all off making this mash super creamy and flavorful.

Why this recipe is great

  • It’s a twist on classic mashed potatoes.
  • It’s a great way to add cruciferous vegetables into your diet.
  • It is naturally gluten-free and grain-free.
  • It is easy to make and easy to customize.
  • It makes for a great side dish for most meals, holiday meals, and Thanksgiving.

Recipe ingredients

Ingredients needed to make cauliflower and potato mash.
  • Gold potatoes– these have a softer sweeter texture than other potatoes, which works great for this recipe.
  • Cauliflower– a large head of cauliflower is used here to mash into the potatoes.
  • Garlic– you’ll need 3 cloves of garlic that you can mince or crush.
  • Butter– use a good quality butter because it really enhances the flavor of the mash.
  • Half and half– I like to use this, heavy cream or whole milk for this recipe.
  • Onion powder– this adds a hint of flavor to the mash.
  • Salt and Pepper– these also season the mash and can be used as much or as little as you like.
  • Nutmeg– I like to add a small sprinkle to my mash but this is totally optional. If you don’t like nutmeg, don’t use it.

See recipe card below for a full list of ingredients and measurements.

Additions/ Substitutions

  • Instead of gold potatoes, you can use russet potatoes or Idaho potatoes.
  • If you don’t like garlic, you can omit it.
  • If you don’t have fresh garlic, you can use 1/2 teaspoon of garlic powder and skip the sautéing part of the recipe.
  • Instead of butter, you can use olive oil or Vegan butter.
  • Instead of half and half, you can use any type of milk of your choice, such as almond milk or oat milk.

Expert tips

  • How to serve– I highly recommend melting extra butter and topping the mash with the butter, salt, and pepper before serving.
  • How to store– store in an airtight container in the refrigerator for 3-5 days.
  • How to make in advance– follow all the instructions and then let the mash cool. Then, cover it and refrigerate until ready to serve (3-4 days). Then you can microwave them for 3-4 minutes or put them into the oven at 350 F for 20 minutes.

  1. OOooo you had me at garlic. Is there a keto version of this dish? Will it keep it’s texture/taste if I do cauliflower only?5 stars

    1. I’m not totally sure what would make it Keto. 😛 I know that sounds crazy but I really haven’t tried that diet so I wouldn’t want to give you incorrect info! You could definitely make this with cauliflower only. I think it would have a thinner texture but it would be delicious. I would put a little less garlic in there to start and add more as you go because the potatoes cover up some of the garlic flavor where I don’t think the cauliflower would. 🙂
