  • 1 head cauliflower cut into florets
  • ¼ cup milk almond or cashew milk
  • 3 Tbsp. olive oil
  • 1 ½ tsp. rosemary fresh
  • 1 ½ tsp. thyme fresh
  • 3-4 cloves roasted garlic
  • ¾-1 tsp. salt to taste
  • 1 pinch black pepper


  1. Roast a head of garlic in the oven. Trim the ends, drizzle on 1 tablespoon of oil, sprinkle with salt, wrap in foil and then bake at 400 degrees for 40-50 minutes. You can do this up to 3 days in advance and store in the refrigerator until ready to use.

  2. Bring a large pot of water to a boil. Boil cauliflower for 10-12 minutes. Drain water and place cauliflower on a towel and dry cauliflower completely before proceeding.

  3. In the bowl of a food processor combine cauliflower, milk, olive oil, rosemary, thyme, roasted garlic cloves, salt, to taste, and a pinch of black pepper.

  4. Puree for 1-2 minutes or until mashed cauliflower is completely smooth. Be sure to scrape down the sides of the bowl every 20-30 seconds to ensure even pureeing.

  5. If mashed cauliflower has cooled too much, return it to the pot and heat it to your desired temperature.

  6. Serve mashed cauliflower with a drizzle of olive oil and a few sprigs of rosemary or thyme and enjoy!
