Add a delicious twist to mashed potatoes with our tasty mustard mash recipe – a quick and easy way to flavour mashed potatoes

Oh I know… this is hardly even a a recipe but it’s just OH SO GOOD I couldn’t help but include it.

Mustard mash is just the most perfect mashed potatoes to go with sausages, pork casserole or a big warming beef stew for a tasty dinner recipe.

The wholegrain mustard just adds an extra delicious twist to regular mashed potatoes and you end up with just the BEST mash!

Best potatoes for mash UK

Okay so first up you need to get the right potatoes for mash. In the UK the best potatoes to use for mashed potatoes are floury potatoes like King Edwards or a good all-rounder like Maris Piper.

But I kinda think the lovely red skinned Desiree make just the BEST mash, smooth, velvety and with a more creamy texture.

Mustard mash ingredients

  • 1.5kg potatoes – peeled and cut into chunky cubes for boiling
  • 100g butter – I use unsalted for mashed potatoes
  • 100ml milk – you can use thick cream if you prefer or if you want to make your mash extra special

How to make mustard mash

  • Boil the potatoes – put the peeled potato chunks into a panful of cold water – I add a pinch of salt to the water. Bring the pan to the boil and then simmer over a low heat for around 20-30 minutes or until the potatoes are tender. Drain the potatoes once cooked.

You should always cook potatoes by starting them off in cold water and bringing them to the boil – if you add them to boiling water the outside cooks quickly and the centre of the potatoes stay hard and uncooked.

  • Mash the potatoes – add the butter to the potatoes and mash using a potato masher until they’re smooth.
  • Add the milk – once the potatoes are smooth, pour in the milk and whip it into the potatoes using a spoon.
  • Add the wholegrain mustard – add the wholegrain mustard to the panful of mashed potatoes.

Make mustard mash your way

We’ve given you the basic mustard mash recipe but feel free to swap and mix things up to make your own perfect flavoured mashed potatoes.

  • Dijon mustard mash – swap out the wholegrain mustard for a spoonful of Dijon mustard to create a smoother, creamy mash.
  • English mustard mash – okay, remember here that English mustard is a whole lot hotter than wholegrain and Dijon mustard so you’ll need a lot less. I’d say probably 2 tsp should do it – but just experiment and find the right amount for your tastes.
  • Cheesy mustard mash – make a delicious cheesy mustard mash by adding 100g grated Cheddar into the mashed potatoes as you mash them with butter so it melts into the potatoes.

Hearty casseroles to serve with mashed potatoes

  • Beef and ale stew – a super easy slow cooker recipe that’s delicious spooned over our wholegrain mustard mashed potatoes.
  • Onion gravy – you could just keep things simple and serve some lovely bangers with mash and pour over the onion gravy!
