With fewer carbs and a lower calorie content than mashed potatoes, this creamy 3-ingredient Mashed Cauliflower is the keto side dish of your dreams! It’s super easy to make with only butter and fresh garlic.



  • 1 head of cauliflower, cut into florets
  • 3 cloves of garlic
  • 2 tablespoons of unsalted butter
  • salt & pepper to season


  1. Cut cauliflower into florets. Place florets and whole garlic cloves in a medium saucepan and add about 1″ of water until the florets are halfway covered. Season with salt. Cover.
  2. Heat to medium-high heat and steam cauliflower for 10-15 minutes, or until fork-tender.
  3. Drain liquid and let cauliflower rest in a colander for 5 minutes.
  4. In the meantime, use the same pan you just cooked cauliflower in and add butter. Melt over medium-low heat.
  5. Next, add cauliflower to a blender or food processor. Pulse until smooth or at your desired consistency. Then pour back into the pan with butter. Stir to incorporate the butter. Season with salt and pepper to taste and serve.
