Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Cut cauliflower into 1.5-inch florets, place on a parchment-lined baking sheet, and toss with 1 tbsp olive oil. Roast for 25-30 minutes until golden and fork-tender, stirring once halfway.
  2. Step 2: Transfer roasted cauliflower to a food processor with butter, chives, dill, heavy cream, salt, and pepper. Blend for 2-3 minutes until completely smooth, scraping down the sides as needed.
  3. Step 3: Return mixture to a saucepan and cook over medium-low heat for 5 minutes, stirring constantly until it thickens to a creamy consistency that coats the back of a spoon.
  4. Step 4: Transfer to a serving dish, sprinkle with flour to form a light crust, and let rest for 5 minutes before serving.

How do I scale Creamy Herb-Crusted Cauliflower Mash for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
