Whether it's a cold Winter's day or I'm feeling a little tired and run down, mashed potatoes have a special place in my heart and in my tummy. I love the creamy goodness. It's basic, but it's homely and warming.
This mashed potato is one of my go-to side dishes that I know everyone will eat. It's the vegetable side dish that everyone loves. This is a very easy recipe, but like all simple dishes, the correct ingredients and technique are the keys to perfection.
I know a lot of people have trouble making perfect mashed potatoes in the Thermomix, so I wanted to share my tips. Thermomix mashed potatoes are a life changer!
This recipe gives you bang for your Thermomix buck because it's family-friendly and it is SO MUCH easier to make in the Thermomix. In the Thermomix, mashed potatoes require almost no input from the cook. It's literally a set-and-forget dish that everyone loves.
Let's take a look at how you would make mashed potatoes if you didn't have a Thermomix.
Perfect Mashed Potato Stove Top Method
The problem with the stovetop method is that for a side dish, mashed potatoes are rather demanding.
- Firstly, you have to peel a kilo of potatoes
- Then cut them into 2-3cm cubes
- Add the potatoes to a large saucepan of salted water
- Bring the water and potatoes to a boil.
- Cook for 15- 20min
- Adjust the heat setting each time the water boils over or comes off the boil.
- Test the larger cubes of potato with a knife to see if they're cooked through
- Drain the potatoes through a sieve
- Add 50g cubed butter and 200g milk and mash by hand. (Don't over-mash) ie: stick blender or food processor won't work *see tips below
Thermomix Mashed Potato
Making mashed potatoes in the Thermomix is a no-brainer because it requires very little effort compared with the stove-top method. This recipe should be used as one of your "go to" basic Thermomix recipes.
I've noticed that when making mashed potatoes, people usually have one of two problems:
the wrong potatoes, or over mashing, so here are my tips.
- Choosing the wrong potato
- Whipping the potato without the butterfuly
Perfect Thermomix Mashed Potato
Choose The Correct Potato for Mashing
It is important to choose the correct type of potato for mashing. The potato needs to be a "floury' variety, not a waxy potato. If you choose a waxy potato, the result is likely to be something that resembles and tastes more like a lumpy glue than a light, fluffy mashed potato.
In Australia, we have a number of readily grown floury potatoes. choose one of these varieties;
- King Edward
- Golden Delight
- Sebago
- Dutch Cream
Be suspicious of any potatoes that are suitable for salads. For potatoes to be suitable for a salad, they require the ability to hold their shape when cooked. This is NOT what we want for a mashed potato! I steer clear of "all-rounder" potatoes for the same reason.
I found this information while reading the Spud Sisters page. They are a large Australian potato farming company, and their site has so much information about the best potato for all purposes. They also introduced me to some gourmet potatoes that look fascinating.
The Correct Cooking Method for Mashing
My next tip is not to add the Butterfly to the TM Bowl until after the potatoes are cooked. There are two reasons for this;
- The butterfly has a tendency to jump off while the potatoes are being cooked. If it remains out of position for the duration of the cook, it can become damaged. Plus, it's annoying to have to try to replace it throughout the cooking time.
- More importantly, when potatoes are mashed, starch is released. The longer the mashing process, the more starch is released. Gluey mashed potato occurs when too much starch gets released. SO we want to minimize the mashing. To do this, we add the butterfly once the potatoes are fully cooked.
- Always use the butterfly for mashing the potatoes as it aerates and whips evenly and quickly.
- To insert the butterfly, just use it to push aside the potato. Then place the hole in the centre of the butterfly over the middle circular upright on the blade. Give the butterfly a quarter-turn clockwise.
What to Serve With Mash Potatoes
If you're looking for the perfect accompaniment for mashed potatoes, take a look at my Maple Syrup Lamb Shanks or my famous Meatballs in tomato sauce. Both of these are personal favourite recipes of mine, and they go brilliantly with light and fluffy Thermomix mashed potato. You could also try adding Thermomix Mash to one of my pie recipes. I have a Guinness Pie and a Peppercorn Meat Pie that are both crying out for a bit of mash.
Alternatives To Potato Mash
If you are trying to avoid potato mash due to the carb loading, why not try puree cauliflower? Cauliflower Mash has earned its place as a substitute for the traditional mashed potato. My loaded Cauliflower Mash recipe makes it an extra special side.
Younger Children
Are you looking for something to serve younger children as a side dish? I have instructions for making vegetable puree in an article about food for toddlers and babies. The vegetable puree can be made as a baby's first food or similar to mash potato and used as a side dish.

I have only ever increased the potato to 1.5kgs and added an extra 5 mins cooking time.
I hope this helps, increase the milk by half also.
