Chef Jenn’s Tips to Make Easy Mashed Cauliflower

  • Use fresh cauliflower not frozen. Frozen cauliflower gives off way too much liquid when you thaw it and you’ll end up with soup instead of mash.
  • Sharp cheddar is the way to go here! You want big and bold cheesy flavor.
  • The mozzarella gives this keto cauliflower mash creaminess and extra cheesiness.
  • If your mash is too runny, pop it into a non-stick skillet or saucepan and stir it over medium heat for a few minutes to evaporate some of the liquid.

What To Serve With Cheesy Mashed Cauliflower

This is a tasty side dish that’ll go amazingly well with a delicious pot roast, beef stew, or even just a gold old roast.

Or, serve it as a side on your holiday table and have plenty of turkey gravy on hand to ladle on top! I also like this keto mashed cauliflower with easy dishes like this keto air fryer sausage recipe.

Is This Easy Mashed Cauliflower Recipe Freezer Friendly?

People do freeze this easy mashed cauliflower recipe, and you can buy keto mashed cauliflower frozen, but you’re going to have a liquid issue.

When cauliflower is frozen and then thawed, it gives off a lot of liquid.

Be prepared to cook the liquid out by evaporating it. Put the mash into a pot or saucepan over medium heat and stir it – without boiling it – until it thickens up.

Because this is such a pain, I recommend eating this simple mashed cauliflower recipe fresh.

Is cauliflower keto?

Absolutely! Cauliflower is the keto wonder vegetable. It is a good source of fiber and is pretty low in carbs making it a great veggie for keto dieters.

Why is my cauliflower mash runny?

It’s got too much liquid in it! Always start with fresh, not frozen cauliflower, and drain it really well after cooking it. If your mashed cauliflower recipe is too runny, you can evaporate some of the liquid out of it by heating it in a non-stick saucepan over medium heat.

How long do you cook cauliflower to make mashed cauliflower?

That depends on how big you’ve cut it. If you cut it into bite-size florets, it can take 4-5 minutes at a boil to get nice and soft. Bigger pieces will take longer.
