How To Make Potato And Cauliflower Mash
- Preheat your oven to 390° F (200° C). Line a large baking sheet with parchment paper.
- Wash and trim your cauliflower. Chop into medium sized florets. Transfer to a bowl and toss with 2 tablespoons of olive oil. Spread out evenly on a baking sheet and roast for 25 minutes.
- At the 10 minute mark add your garlic cloves (skin on) to the baking sheet. Drizzle with a bit of olive oil, and carry on roasting for the remaining 15 minutes.
- Meanwhile, bring a large pot of water to a boil. Add a bit of salt and boil the potatoes for about 25 minutes. They should be fork tender. Drain, reserving ¼ cup of the cooking liquid.
- Return the potatoes to the empty pan. Over very low heat, steam them for two minutes to remove any excess water. Give the pan a few shakes to prevent them sticking to the pan and burning.
- Squeeze the garlic cloves out of their skins. Add your roasted cauliflower and garlic to a food processor with 1½ tablespoons of olive oil, 2 tablespoons of the potato cooking water and the thyme. Season with salt and pepper. Puree until smooth.
- Using a potato ricer or a masher, mash the potatoes with two tablespoons of olive oil. Add the reserved starchy potato water 1 tablespoon at a time until you get the consistency you like.
- Fold the cauliflower and garlic puree into the mashed potatoes. Adjust seasonings and serve.
