Would you like a super easy side dish recipe that just so happens to be good for you, too? I thought you might! We make cauli mash regularly for dinner and, of all the variations we've tried, these are our favorite.

Why we believe these are the best cauliflower mashed potatoes

  • They are good enough to trick a diehard mashed potatoes fan into thinking they're the real deal. ← This actually happened.
  • Boursin cheese, the best cheese ever. ← The one thing the entire universe seems to agree on.
  • 3 ingredients = a super simple side dish.
  • The best side for a meat and gravy dinner. Think roast chicken, roast beef, or Thanksgiving and Christmas dinners.
  • But this mashed cauliflower recipe is so creamy that it doesn't need gravy. Serve it beside steak or pan-fried chicken for a quick and easy weeknight meal.
  • WAY easier to make than mashed potatoes, this mashed cauliflower recipe is light, fluffy, and perfectly flavored.
  • It's a healthy vegetarian + low-carb recipe that won't leave you feeling like you're missing out.

How to make cauliflower mash

To make the best cauliflower mashed potatoes, lightly steam the cauliflower making sure not to overcook it. You don't want it to turn soggy or limp or you will have thin, runny cauli mash. To make thick, creamy, fluffy mashed potatoes, don't overcook the cauliflower!

  1. Cut the cauliflower into smallish pieces (see the picture above) and put them into a large pot with 1 cup of water.
  2. Now bring the pot to a boil and steam the cauliflower for 10 minutes. Drain any remaining water from the pot then put the cauliflower into your food processor.
  3. Add the Boursin cheese and blend the cauliflower until it is light and creamy.
  4. Season! Please don't forget this part. Just like potatoes, cauliflower is bland without salt.

We like to put a pat of butter and a sprinkle of chives on top of the bowl of mashed cauliflower as it looks pretty for serving. But if you're serving yourself from the stove, you can skip this step.

What is Boursin cheese?

In case you haven't yet met the best cheese in the world, let me introduce you to Boursin. It's soft and creamy and delicately flavored with herbs and garlic. Technically a brand of Gournay cheese, it's like whipped cream cheese got together with crumbly goat cheese and this is their love child.

Boursin cheese substitute

While there is no exact substitute for Boursin cheese (thank goodness it's widely available!), you can use some cream cheese or goat cheese with a tiny sprinkle of Italian seasoning to mimic the creaminess and flavor.

What to serve with cauliflower mashed potatoes

Mashed cauliflower can be served anytime you would traditionally serve mashed potatoes. We love it with all of our roast chicken recipes:

Roast chicken with this mashed cauliflower recipe and a simple green salad tossed in one of our favorite salad dressing recipes makes a delicious meal.

You can also serve cauli mash with Coq au Vin, Juicy Baked Chicken Thighs, Perfect Baked Chicken Breasts, or BBQ Crockpot Beef Ribs.

Because cauliflower mashed potatoes are a 2 in 1 carb-like veggie side, we sometimes keep dinner ultra simple and make this recipe with our 18 minute Juicy Baked Pork Chops and call it dinner.
