Ingredients in this vegetable side dish

Simple ingredients are used in this cauliflower sweet potato mash:

Cauliflower – Crunchy, fresh cauliflower cut into florets.

Sweet potato –  I use orange sweet potato in this recipe. It’s the type I use most often, and I love the colour it adds. It’s colour means that it’s actually a good source of beta-carotene, which converts to Vitamin A in the body to maintain healthy eyes [1].  Another great reason to add this side dish to the dinner rotation! 

Garlic powder – Normally I would opt for fresh garlic cloves over ground, but it’s easier to mix in ground garlic powder. And this is meant to be a simple side dish! 

White pepper – White pepper is a more mild seasoning than black pepper. Substitute if you like.

Butter and milk – To add creaminess to the mash. I always use unsalted butter and full fat regular milk.

How to make this delicious mash

Thermomixer? Making this mash recipe is really easy in a Thermomix or other thermo cooker. Use the machine to steam the sweet potato and cauliflower, and then drain the mixing bowl. Add back in the sweet potato and cauliflower florets with the butter, and mix. Then insert the butterfly whisk and remaining ingredients to blend this mash to silky smooth.

Conventional cook? On the stovetop in a steamer basket over medium-high heat, steam the sweet potato and cauliflower florets until tender. If you want it to be a really smooth mash, you’ll need to use a food processor or immersion blender. Into the food processor/blender bowl add the butter, steamed cauliflower and sweet potato, milk, garlic powder and pepper. Blend until smooth. Don’t have an appliance? You can still make this recipe, it’ll just take some extra effort! With a potato masher, give the sweet potato, cauliflower and butter a good mash. Add in the milk, garlic powder and pepper, and keep on mashing until you’re happy with the consistency.

Serving Cauliflower and Sweet Potato Mash

For a little more indulgence, serve this mashed sweet potatoes and cauliflower with a little butter on top or grated parmesan cheese sprinkled over. This dish can be served with a variety of main dishes. We’ll often have it with steak, sausages or pork chops, or this Beef Topside Pot Roast for a weekend family dinner. I think mashed potatoes with a saucy roast or stew is the ultimate winter comfort food, but you can enjoy this dish any time of year!  The combination of sweet potatoes and cauliflower isn’t overpowering, but it’s way more flavourful than regular mashed potatoes and the perfect side dish to so many meals.

    Just love mashed potatoes and sweet potato adds a special, subtle flavour. I used the old fashioned method to make this, as I don’t have a Thermomix. Great stuff Chloe.
