- Food processor or quality blender
- 2 large heads of cauliflower (about 5 cups, chopped)
- ¼ cup heavy whipping cream
- 4 tablespoons salted butter
- 3 cloves garlic, minced
- ⅓ cup sour cream
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper, plus more to taste
How To Make It
Prep the cauliflower:
Chop the cauliflower into small florets (about 5 cups total).

Cook until soft:
Bring a large pot of salted water (½ tablespoon salt) to a boil. Add the cauliflower and cook until very tender, about 15 minutes. Drain well.

Sauté the garlic:
In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook for 1 minute, just until fragrant. Be careful not to let it brown. *Do not skip this step. Do not add raw garlic to the cauliflower- it will be spicy and not in a good way. Don’t ask how I know 🙃
Blend it all together:
Add the cooked cauliflower, melted garlic butter, sour cream, salt, and pepper to a food processor. Pulse until well combined. (Work in batches if your processor is small.)

Add the cream:
With the processor running, slowly add the heavy cream—one tablespoon at a time—until the mixture is smooth, creamy, and fluffy.
Season to taste:
Taste and adjust with more salt or pepper if needed.
Serve warm and enjoy!
Spoon into a serving dish and top with a pat of butter or sprinkle of herbs if desired.

FAQ’s
Can I make mashed cauliflower ahead of time?
Yes! Make it up to 2 days in advance, then reheat gently with a splash of cream or butter.
Can I use frozen cauliflower?
Yes. Steam according to package directions, then drain well before blending to avoid extra moisture.
What’s the best tool for mashing?
A food processor gives a super-smooth finish. For a chunkier, rustic mash, use a hand masher or immersion blender.
Can I freeze mashed cauliflower?
Absolutely! Store in an airtight container for up to 2 months. Thaw overnight and reheat on the stovetop before serving.
How do I make it thicker?
If your mash turns out too thin, stir in a bit more sour cream or shredded cheese, or reheat to let some moisture evaporate.
