Lightened-up Creamy Cauliflower and Mashed Potatoes is a healthier side dish made with half cauliflower and half potatoes. Velvety smooth and flavorful with fewer carbs and no milk, sour cream, or butter. Elegant enough for Thanksgiving or Christmas, yet simple enough for weeknight dinners.
Over the past few months I’ve focused more on self-care and nutrition. By tracking macros I’ve lost weight and feel better overall. When the holidays roll around I don’t want to sacrifice flavor, so I look for simple swaps that make classic dishes lighter without losing the taste that makes them special.
Replacing part of the potatoes with cauliflower is one of those swaps. It lowers carbs and calories while keeping the creamy texture most of us expect from mashed potatoes.
Does Cauliflower Really Taste Like Mashed Potatoes?
Pure cauliflower “mashed potatoes” don’t deliver the same flavor or mouthfeel as real mashed potatoes. I enjoy cauliflower, but when it’s meant to replace potatoes entirely the result can feel off. The simple solution is to mix them.
Using half potatoes and half cauliflower gives you the familiar texture of mashed potatoes while cutting carbs and calories. My kids, who are picky eaters, loved this version. They knew cauliflower was in it but said it tasted like regular mashed potatoes—if I hadn’t told them, they likely wouldn’t have noticed.
That makes this recipe a great way to add vegetables to a crowd-pleasing side dish.
Trick for Super Smooth Cauliflower Mashed Potatoes
For a silky texture use a potato ricer to press the cooked vegetables. This produces a light, lump-free result without overworking the starch in the potatoes.
I steam both the cauliflower and potatoes together in an Instant Pot for about 7 minutes; the cauliflower will be very soft and the potatoes will be tender but still hold up, which balances the texture. You can also steam or boil them separately if you prefer.
To make the mash creamy and well seasoned, stir in 2–3 wedges of soft cheese, extra minced garlic, salt and pepper, and a little of the reserved cooking liquid until you reach the desired consistency. The cooking liquid helps thin the mash without adding dairy.
This recipe is on my holiday menu. One serving (about 1/2 cup) is roughly 95 calories and offers a favorable macro balance for a lighter side: lower carbs, minimal fat, and a modest amount of protein.
Creamy Cauliflower and Mashed Potatoes
Ingredients
- 1 lb potatoes, peeled and diced (about 3 cups; 2–3 potatoes, any variety)
- 1 lb cauliflower florets, about 3 cups (1 head)

- cooking liquid, reserved from steaming or boiling
Instructions
-
Boil or steam the diced potatoes and cauliflower florets until very soft, either together or separately.

If using an Instant Pot: pour 1 cup water into the pot, place a steamer basket inside, add the vegetables, cook on high pressure for 6–7 minutes, then quick release.

Remove the vegetables and reserve the cooking liquid. Press them through a potato ricer, mash with a masher, or beat with an electric mixer until smooth.
