Cauliflower is a commonly used vegetable for low-carbers, especially to replace potato. Horseradish is the perfect addition that really lifts this vegetable and makes a tasty side dish!

Of course you can use a whole head of cauliflower to make this dish - but I usually use microwave steam-in-the-bag florets. I find that if I boil cauliflower the florets can end up too watery. For four servings, use two 10oz bags, and cook them until the cauliflower is super soft, around 7 minutes.
How to Make Horseradish Cauliflower Mash
Once the cauliflower is cooked, add cream cheese, prepared horseradish and seasoning, and mash everything together. I taste-test several times to get just the right amount of horseradish heat!
Season with salt and pepper. I prefer to use a potato masher and mash by hand - but for a smoother result (but more washing up!), you could whizz it all up in a food processor.
Transfer the mash to a serving bowl and sprinkle some finely chopped herbs like parsley or chives over the top. Grind some extra black pepper over and finish with a couple of slices of butter.
My non low-carbing husband actually prefers this dish to mashed potatoes as it is just as filling but doesn't leave him feeling too full. So this is a great side dish for mixed company! It makes a wonderful accompaniment to meat dishes like Baked Balsamic Chicken Thighs, Garlic Butter Pork Chops, or Herb Crusted Roast Beef.
