When mashed cauliflower won’t cut it for your family, but you are trying to eat a little healthier.  These cauliflower mashed potatoes are made with a 50/50 blend of cauliflower and potatoes so they taste and feel like your beloved mashed potatoes but have a little added nutrients and a few less carbs.  Win win!  Plus they are vegan too.


  • 1 cauliflower head
  • 6 russet potatoes
  • 6 tbsp vegan butter
  • 1/2 cup dairy free milk
  • 3 tsp fresh rosemary – minced
  • 3 tsp salt
  • 3 tsp garlic powder
  • 1 tsp black pepper
  • 1/2 cup of potato water


  1. Put a large pot of salted water over medium to high heat, cover, and bring to a boil.
  2. Cut cauliflower into a few large chunks, peel your potatoes and cut them in half, put them in the pot once it is boiling.  You will boil until each veggie is tender to a fork.  I left my cauliflower in for about 15 minutes and left my potatoes in 5-10 minutes longer.
  3. Remove the cauliflower from the water with a slotted spoon, and transfer to a food processor.  Add all spices and puree.  In a small bowl, melt your butter, combine it with your milk, and then slowly incorporate this into the cauliflower mixture. (Note if you taste this it will taste too strong, that is okay, because we are mixing it with the potatoes!).
  4. When the potatoes are ready, transfer to a new bowl, pour the potato water over them, and mash until minimal lumps remain. 
  5. Fold in the cauliflower mixture to the potatoes and keep mashing until well combined.


This recipe is for a BIG batch, this will probably feed a family of 6.  I made it this way with Thanksgiving in mind, but if you are serving a smaller crowd or just making this for a regular family dinner, just cut the recipe in half! It is super easy to do.
