Think mashed cauliflower can’t rival mashed potatoes? Think again! This cauliflower puree with sour cream and cheddar is so rich and creamy, your tastebuds will be singing.
I am not going stand before you and pretend that mashed cauliflower tastes exactly like mashed potatoes. I respect you far too much to be that disingenuous.
However, I am going show you exactly how to make the richest, creamiest, most flavourful mashed cauliflower recipe on the planet. And I urge to embrace this keto side dish for all that it is. Healthy, low carb, and absolutely delicious.
I’ve had this recipe for cauliflower mashed potatoes on the blog since 2013. And every time I take a bite, I remember why I love it so much. I think you will love it too.
Pair it with turkey for your Keto Thanksgiving celebrations, or use it to top Keto Shepherd’s Pie. Either way, it’s delicious!
Why you will love it
Cauliflower is just about the most keto friendly vegetable you can eat, and it’s also one of the most versatile. It’s a veritable shape shifter of a vegetable, willing to play the role often filled by starchy side dishes like potato or rice.
Now as far as mashed cauliflower is concerned, don’t try to fool your tastebuds. If you’re a serious mashed potato fan, you won’t think it tastes exactly the same. But you can love it for what it is – a healthy, delicious alternative.
The trick is to get it really creamy and smooth, but not too thin or watery. Adding sour cream and grated cheddar is key to a rich, thick consistency with amazing flavor. A little garlic doesn’t hurt either!
And since cauliflower doesn’t fill you up as much as real spuds do, you can eat far more of it in one sitting. With only 4.2g net carbs, you can have a nice big serving and not have to loosen your belt after dinner.
Reader Testimonials

Ingredients you need
- Cauliflower: A large head of cauliflower is about 1 ¾ pounds, and should yield about 6 cups when chopped into florets. You can use the stem of the cauliflower, too, as long as you cook it until fork tender. Frozen cauliflower works well too and you can cook it right from frozen.
- Garlic: Since cauliflower has such a mild flavor, I steam and mash it with a few cloves of garlic.
- Sour cream: Use full fat sour cream as low fat tends to have fillers and can be higher in carbs. You can also use full fat thick Greek yogurt.
- Cheddar cheese: I love using sharp white cheddar for the best flavor. I recommend grating it yourself, rather than purchasing shredded cheese.
- Salt and pepper
Step-by-step directions
1. Steam the cauliflower: Fill a large saucepan with about 1 inch of water. Add the cauliflower and garlic cloves and set over medium high heat. Cook until the cauliflower is fork tender, about 7 to 10 minutes.
2. Drain well: Drain into a colander or sieve and shake to release as much excess moisture as possible. Let it sit a few minutes to drain fully, as it will continue to release moisture.
3. Puree: Transfer the cauliflower and garlic to a food processor or high powered blender and add the sour cream. Puree until smooth, scraping down the sides of the bowl or jar a few times to help move the bigger pieces so the blades can catch them.
4. Add the cheese: Return the puree to the cooking pot and add the grated cheddar. Set over low heat to help melt the cheese and reduce excess moisture. Stir until smooth. Season with salt and pepper and serve.
Expert tips
The most common complaint you hear about cauliflower mashed potatoes is that they are too thin and watery. But they don’t have to be! Follow the steps I provide in the recipe and they should turn out rich and thick from the start.
However, if you still find yours a bit thin, you have a few options. You can add a litle softened cream cheese to the pot in the final step and stir until melted. Or you can add a keto thickener like glucomannan or xanthan gum.
Be sure to whisk it in well when the mashed cauliflower is hot. You don’t need more than about ¼ teaspoon per head of cauliflower.
Variations
Feel free to play with the flavors of this mashed cauliflower recipe. Here are some tasty ideas:
- Add crumbled bacon and chopped green onion for “loaded” cauliflower mash.
- Use Pepper Jack in place of the cheddar.
- Stir in goat cheese in place of the sour cream.
- Replace the cheddar with Parmesan and add some rosemary or Italian herbs.

The cauliflower was tasty and creamy. I used frozen cauliflower. Followed the the basic recipe however, we like a lot of spice in our food so I added about a tablespoon of Italian seasoning, two shakes of Tumeric, lots of black pepper, and salt. The cauliflower mash was delicious and it was a great side dish for the very spicy cod main dish.
Thanks for another great recipe! Will definitely make this again.Reply

Hi Carolyn, I made this in combination with the meatball casserole. Great comfort food! It will now be my go to for a potato substitute, perhaps along with some gravy! I only had a “bullet ” to puree it with but I just did small amounts at a time and it worked just fine!

I am 76 years old, and while I LIVE garlic, it REALLY does not love me back. Is there another seasoning I can use to help boost the flavor? Thanks for any help. My husband I love your recipes and I cook at least one of your recipes every day.Reply
