  • Food mill, stand mixer, or potato masher.


  • 1 medium head cauliflower, leaves removed
  • 1 Tbsp olive oil
  • pinch salt and pepper (to season the cauliflower while baking)
  • 4 medium yukon gold potatoes
  • kosher salt (for cooking water)
  • 2 Tbsp vegan butter (plus more, for serving)
  • 2 Tbsp non-dairy full fat milk (I used oat)
  • ¼ tsp roasted garlic powder
  • salt and freshly ground black pepper, to taste


  • Preheat your oven to 375°F (190°C). Place your cauliflower in a baking pan or a Dutch / French oven with a lid that will close over it. I use a Staub cast iron cooking vessel with a glass lid but you can use a baking pan and cover with foil.
  • Fill your cooking vessel with a little water (just enough to cover the bottom) and drizzle the cauliflower with a little olive oil and sprinkle with salt and pepper. Cook, covered, for 40 minutes.
  • While your cauliflower is cooking, fill a cooking pot with water and salt generously. Add your yukon golds whole with skin on, and bring to a boil. Boil until fully cooked and tender inside, about 30 minutes.
  • When your potatoes are cooked, remove from the water and allow to cool enough to be handled. Remove the skins with your hands, and set aside.
  • Cut your cauliflower into manageable pieces (it should be very soft now) and place with the peeled potatoes.
  • Using either a stand mixer (I use the whisk attachment), a food mill, or a potato masher, mash both the potatoes and the cauliflower and mix. Add your vegan butter, non-dairy milk, and garlic powder. Mix well until creamy. Add salt and pepper to taste, and serve immediately.
