Ingredients needed

This cauliflower mash recipe requires only a few simple ingredients to make and is the perfect side dish to any meal. Plus, this recipe is even easier to make than regular mashed potatoes. Here’s what you’ll need:

Cauliflower: We’re using one full head of cauliflower. We recommend fresh cauliflower for the best flavor and texture.
Butter: You can’t have cauliflower mashed “potatoes” without butter! Feel free to use salted or unsalted butter, and even vegan butter works to make this recipe completely dairy free.
Garlic: Sautéed garlic adds so much flavor. Nothing beats garlicky mashed potatoes, and this mashed cauliflower tastes just like the regular version.
Seasonings: Add plenty of sea salt and pepper to bring out all of the flavors. We also like to garnish with fresh herbs, like thyme sprigs or even chives. Parsley would be great too.

How to make this recipe

For full, printable instructions, reference the recipe card at the bottom of the post.

Prep the cauliflower: Trim the leaves off the cauliflower, remove the core and cut into florets.
Cook cauliflower: Bring a couple inches of water to a boil in a medium pot. Place a steamer insert in the pot, add the cauliflower florets and steam for 8-10 minutes or until fork tender.

Sauté the garlic: While the cauliflower is steaming, heat the butter in a small sauce pan on medium-low heat. Add the garlic and cook until fragrant (20-40 seconds), then remove from heat. Be careful not to burn the garlic.

Combine + blend ingredients: Remove the steamed cauliflower from the pot and place in a food processor. Add the olive oil, garlic, and a pinch of sea salt. Blend until the cauliflower is smooth (it will still have texture). Taste and adjust seasonings to your liking.
Serve: Transfer to a serving bowl and top with an extra pat of butter, sprinkle of black pepper and fresh thyme. Serve and enjoy.

Expert tips

Cut your cauliflower into similar-sized pieces, so that it will all cook at the same rate. This helps it cook consistently and faster than just steaming large pieces of cauliflower.
Drain all of the liquid. Make sure the cauliflower is fully drained before adding it to the food processor. We recommend letting it sit in the colander for at least a minute and give it a couple of good shakes to make sure all of the water has drained.
Taste & season. Cauliflower doesn’t absorb salt the same way potatoes do, so it’s best to use less and taste as you season, so this dish doesn’t taste too salty.
We prefer to use a food processor for the creamiest result, but you can also make a chunky mixture by using a potato masher.
