How to make keto cauliflower mash
No endless peeling of potatoes for a creamy bowl of mash here! As well as tasting great, mashed cauliflower is much quicker to make.
For this recipe we added garlic cloves when boiling the cauliflower. This gives a creamy garlic taste but can be omitted if you are not a garlic fan.
Mashing the cauliflower can be done by hand with a potato masher or you can make a smooth puree in the food processor. A hand held blender will work too.
We boiled the cauliflower but it could be steamed or even roasted.
This recipe has just 5 ingredients. There are variations in the recipe tips below too.
- Cauliflower - chose a firm head of cauliflower.
- Garlic - entirely optional. We enjoy our garlic.
- Butter - no mashed vegetable is complete without butter.
- Sour cream - Creme fraiche could be substituted.
- Chives - Fresh chives are best. Parsley could be substituted.
Make it dairy free
For a dairy free and vegan side dish, swap the butter for olive or avocado oil.
What to serve with cauliflower mash
Mashed cauliflower goes with any dish where you would normally serve mashed potatoes. Hearty roasts, stews or any main dish with a sauce or gravy. Try it with our chicken piccata, Mediterranean roasted chicken or chicken Florentine crepes.
Leftover Cauliflower Mash
Any leftover cauliflower mash can be frozen for another day, but try our cauliflower balls recipe for a tasty side dish, appetizer or snack.
If the cauliflower mash is too watery, add cream cheese to thicken it.
For a cheesy mashed cauliflower dish, add cheeses such as Parmesan, Cheddar, Gruyere or even goats cheese.
Try different fresh herbs like sage, dill or parsley.
Crispy bacon bits added to the mash will take the dish to a firm family favourite.
Make this dish in advance and reheat it just as you would mashed potatoes.
