  • 1 medium head of cauliflower, chopped
  • 1/2 medium white onion, chopped
  • 8 cloves garlic, peeled and smashed
  • 2 tablespoons olive oil
  • 1/8 teaspoon salt
  • 1/8 teaspoon pepper
  • 1/3 cup broth (any kind)*
  • 1/3 cup sour cream
  • 1/4 cup nonfat Greek yogurt
  • 2 tablespoons butter (+ more for topping)


  1. Preheat the oven to 400ºF.
  2. Next, spread cauliflower, onion, and garlic onto the baking sheet. Drizzle with olive oil and season with salt and pepper and toss until all vegetables are covered.
  3. Bake at 400ºF for 35-40 minutes, tossing halfway. You want to make sure that the cauliflower is tender and golden brown.
  4. Remove from the oven and transfer cauliflower, onion, and garlic into a high-speed blender (we use a Vitamix).
  5. Add broth, sour cream, Greek yogurt, and butter to the Vitamix and blend until smooth.
  6. You may need to add a little bit more broth depending on how thick your cauliflower mashed potatoes are. Add broth by the tablespoon until you’ve reached the desired consistency.
  7. Top with more butter as desired, cracked black pepper, and fresh parsley.
