When a mashed potato craving hits but you want something lighter on the plate, this is the one. A whole head of roasted garlic goes into this Roasted Garlic Mashed Cauliflower, and that’s exactly why nobody guesses it’s cauliflower. Sweet, jammy, SO creamy, and ready in 20 minutes.
Bring a large pot of water to a boil. Add the cauliflower florets and boil for 8-10 minutes, or until tender. Transfer to a colander and drain, then spread out on a dish towel and pat dry.
1 large cauliflower head
Add the cauliflower to a food processor along with the butter, milk, roasted garlic, rosemary, thyme, salt, and black pepper. Process for 1 minute and then scrape down the sides. Continue processing for 1 more minute, or until the mixture is smooth and mashed potato-like in texture. Cover and keep warm until ready to serve.
2 tablespoons salted butter, ¼ cup whole milk, 4 cloves roasted garlic, ½ teaspoon finely chopped fresh rosemary, ½ teaspoon finely chopped fresh thyme, 1 teaspoon salt, ¼ teaspoon black pepper
Serve garlic mashed cauliflower with a drizzle of olive oil and a few sprigs of rosemary or thyme.

Notes
Food processor only: Do NOT use a Vitamix or high-speed blender. You will end up with overly-blended and runny cauliflower mashed potatoes.
Roasted garlic:Roast a head of garlic in the oven. Trim the ends, drizzle on 1 tablespoon of oil, sprinkle with salt, wrap in foil, and then bake at 400 degrees for 40-50 minutes. You can do this up to 3 days in advance and store in the refrigerator until ready to use.
Dry the cauliflower: Spread the drained florets on a dish towel and pat them dry before they go into the food processor. Any water left behind makes the mash soupy instead of fluffy.
Dairy-free: Swap the butter for a non-dairy alternative such as Miyoko’s and use a full-fat plant milk like oat, soy, or cashew.
Make ahead: The mashed cauliflower can be fully made ahead and stored in the fridge. Just reheat it on the stovetop or in the microwave, stirring occasionally for even heating.
Storage: Store leftovers in an airtight container for up to 4 days. Reheat on the stovetop over low heat or in the microwave, adding a splash of milk or broth if needed to loosen the consistency.
Freezing: Let the mashed cauliflower cool completely, then freeze in an airtight container for up to 1 month. The texture comes back looser and a little grainier than fresh, so thaw it overnight in the fridge and reheat on the stovetop with a splash of milk.
