Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

• ½ large head cauliflower (about 4 cups medium-large florets)

• 3 cloves garlic

• ½ tablespoon olive oil

• 2 lbs Yukon gold potatoes (or yellow potatoes)

• 2 tablespoons thick yogurt (Greek, Skyr, or dairy-free variety)

• 2 tablespoons butter (divided; vegan butter works too)

• 4–5 tablespoons unsweetened cashew milk (or milk of choice)

• ½ teaspoon salt (to taste)

• 1 tablespoon freshly chopped chives

Directions

1. Cook the potatoes:
   Bring a large pot of water to a boil. Peel and chop the potatoes into medium cubes. Add to boiling water and reduce heat to low-medium. Simmer for 12–15 minutes, or until tender. Drain and let sit for 2–3 minutes to remove excess moisture.

2. Roast the cauliflower and garlic:
   Preheat oven to 375°F. Line a baking sheet with parchment or foil. Chop the cauliflower into florets. Place cauliflower and garlic cloves on the baking sheet and drizzle with olive oil. Toss to coat. Roast for 15–20 minutes until lightly golden.

3. Process the cauliflower mixture:
   Transfer roasted cauliflower and garlic to a food processor. Pulse a few times to break down. Add 1 tablespoon butter and 2 tablespoons yogurt, and pulse again until finely blended, scraping down the sides as needed.

4. Combine and mash:
   Add the drained potatoes to a large bowl with the cauliflower mixture, remaining 1 tablespoon butter, and salt. Mash using a potato masher or low-speed hand mixer. Slowly add in milk, 1–2 tablespoons at a time, until desired consistency is reached.

5. Finish and serve:
   Mix in the chopped chives. Taste and adjust seasoning as needed. Transfer to a serving dish, garnish with extra chives and a pat of butter if desired. Serve warm.

Can I use a different type of potato?
