What pressure cooker to use
To cook mashed potatoes in the instant pot, we have an Instant Pot Duo 7-in-1 6 Qt, which works perfectly. It has loads of functions and is really easy to clean once you've finished cooking in it. Not only is it a pressure cooker but it can also be used as a slow cooker and a yogurt maker!
How long does it really take?
How many times have you seen an Instant Pot recipe that says "7 Minute Instant Pot Chicken" and then you realise that the times don't include any pressure build up and release?! This recipe takes 20 minutes from start to finish. That time includes preparing the potatoes, getting to temperature, building the pressure, pressure cooking, steam release and finishing off.
Do I need an Instant Pot?
No Instant Pot or Pressure cooker? No problem. We have a recipe for a super Creamy Mashed Potato that can be made on the hob (stove top).
FAQs
Choose higher starch potatoes, like Maris Piper or King Edwards, for the fluffiest and smoothest mash. Waxy potatoes (such as Charlotte or Jersey Royals) require more mashing to become creamy. Russets or Yukon Golds also make light, fluffy mashed potato.
Potatoes are naturally vegan, however the milk and butter we have used isn't. But there are still lots of ways to make creamy vegan mashed potatoes. You can add almond milk and a vegan butter, or you can also use olive oil or hummus to make it creamy.
Leftovers can be used to mashed potato "cakes". Simply mix the mashed potato with some cheese, eggs and milk and form in to patties. Fry them in a little oil for 3-4 minutes each side until nice and crispy.
The leftovers could be used as the topping for a pie, or you could make croquettes or gnocchi with it.
Yes, mashed potato freezes really well. Of course it will always taste better fresh, but it is definitely freezeable. Once mashed and cooled down, put it in to freezer bags, flatten down and then lay flat in the freezer. You can keep it there for about 2 months. Defrost it at room temperature (this will take around 6 hours).
To reheat the mashed potato, put it in a pan with a little more milk and butter to stop it drying out and heat through, stirring regularly.
Add-ins
Next time you cook mashed potatoes in the Instant Pot, why not try adding some of the following:
- If you want to add some extra fibre keep them skin on.
- Cream cheese (garlic, herb, or plain all work) stirred in at the end.
- Fresh herbs (chives and parsley are nice and fresh, but woody herbs like thyme and rosemary are delicious too)
- Olive oil: use this instead of butter for a creamy vegan mashed potato
- Add some veg by cooking some cauliflower with the potatoes and mashing them together.
- Cheese and chopped cooked bacon (total comfort food), added at the end.
- A spoonful of pesto in mashed potato is amazing.
- Like things spicy? Add a spoonful of chipotle paste. It makes it a great colour too.
- Add some greens with some finely chopped spinach.
- A pinch of smoked paprika adds lots of flavour.
- Another vegan way to make creamy potatoes is with hummus.
- A spoonful of horseradish is another way to make it spicy.
- For some Spanish flavour, add some chopped cooked chorizo at the end.
