Ingredients
- Fresh cauliflower florets: This is the star and makes the mash light and fluffy always choose a firm white head with tightly packed florets
- Roasted garlic: Adds a deep sweet flavor and brings a savory punch roast fresh cloves for the best taste
- Grated Parmesan cheese: Gives the dish that cheesy richness use good quality Parmesan for maximum flavor
- Milk or broth: Helps the texture become silky smooth use whole milk for creaminess or low-sodium broth for extra flavor without dairy
- Butter: Adds classic creaminess and helps everything blend together choose unsalted so you can control the salt level
- Salt and pepper: For balance and seasoning taste as you go so it is never too salty
Instructions
- Prep the Cauliflower:
- Trim away any green leaves and break the cauliflower into even sized florets so they will cook quickly and evenly. Rinse well in cold water and pat dry with a towel.
- Steam the Cauliflower:
- Place the cauliflower florets in your steamer basket and cover. Steam over simmering water for about ten to twelve minutes until completely fork tender. Do not undercook or your mash will be lumpy.
- Roast the Garlic:
- Wrap peeled garlic cloves in foil with a tiny drizzle of oil. Roast in a hot oven at four hundred degrees Fahrenheit for about fifteen minutes. The cloves should be soft and golden with a caramelized aroma.
- Mash Everything Together:
- Transfer the hot cauliflower and roasted garlic into a large bowl or your blender. Add grated Parmesan butter a splash of milk or broth and a generous pinch of salt and pepper.
- Blend or Mash Until Smooth:
- Start mashing everything together with your masher or use a blender for extra smooth texture. Add a bit more milk or broth to adjust the consistency. Scrape down the sides as needed for even mixing.
- Taste and Serve:
- Taste your mash for seasoning and texture. Adjust salt or add a touch more butter if extra richness is needed. Serve warm garnished with extra Parmesan or a sprinkle of fresh chives if you like.

My favorite thing about this recipe is how the roasted garlic adds so much flavor you barely need much salt. The first year my family tried this dish at Thanksgiving everyone wanted a second helping and nobody asked for regular mashed potatoes.
Storage Tips
Store leftovers in an airtight container in the fridge for up to four days. Reheat gently in the microwave or on the stove with a splash of milk to restore creaminess. This mash will set up a bit when cold but loosens up beautifully once heated.
Ingredient Substitutions
For a dairy free option swap out butter for olive oil or vegan butter. Nutritional yeast can add a cheesy flavor if you skip the Parmesan. Any good vegetable broth works if you want to avoid milk. Feel free to toss in fresh herbs like parsley or thyme for a different spin.
Serving Suggestions
Serve this fluffy mash alongside roast chicken grilled fish or a hearty vegetable stew. It makes a show stopping topping for cottage pie and works as a lighter side for any holiday meal. Top with extra roasted garlic or finish with a trickle of herbed olive oil for an elegant touch.
