Ingredients for Easy Mashed Potatoes
So here are the ingredients for making mashed potatoes.
As we are using the no drain method, the quantities - especially the ratio of potato to the boiling liquid is important.
You don't want it too runny or too stiff that you end up with a burn sign!
Basic Ingredients for Mashed Potatoes
just potatoes, water, Butter- a generous amount..as mush as your can afford..lol...,garlic..as much as you like..salt and cream.You can use sour cream or cream cheese to make it richer..Especially for your special occasions and holidays! or you can make it healthier by using minimum butter(but some please! lol) and greek yogurt instead!
Potatoes
If you can, always get Yukon gold because they have higher starch content. They also make a creamier mashed potatoes with even little butter or fat because of their naturally buttery taste.
Russet potatoes are also a great choice for soft pillowy mashed potatoes. They also have high starch content.
If you can't find either, look for yellow potatoes that are not sweet tasting.
Butter
A generous amount..as mush as your can afford..lol..
For Vegan version, I would suggest you get a vegan butter instead of substituting with oil because you want that tell tale butter taste in the mashed potatoes.
If you are using salted butter, be mind-full of the salt you add while pressure cooking. You can always leave it out and adjust it at the end.
Garlic
There isn't another ingredient I love as much as garlic! You can use fresh garlic or amp up the flavor another notch by using Roasted Garlic. Here is a super easy way to Roast garlic in the Air fryer. It's takes a lot lesser time than the oven!
Milk
Use whole milk or kick up the flavour a notch by using heavy cream instead.It will give the mashed potatoes a richer feel.
You can also use sour cream or cream cheese in the mashed potatoes.
In fact, you can make slightly healthier but nonetheless heavenly version of mashed potatoes by adding greek yogurt instead.
Vegan Mashed Potatoes
You can make absolutely delicious mashed potatoes without using any dairy whatsoever! I promise!
You can use non diary milk and cream alternatives like oat milk, cashew milk or pistachio milk instead. You can also whip up vegan cream by blending soaked cashews in a blender.
For fat, instead of dairy butter, you can use non dairy butter or avocado oil. Don't use oil like coconut and extra virgin olive oil as they will alter the taste a bit.
Do you need to Peel the potatoes
When I am making the mashed potatoes just for myself or my family of 3, I am not too picky. The potato peel carries a fair bit of nutrition.
When I making these Instant Pot Mashed Potatoes using the No Drain method, all you need to do then is just cube the potatoes with the skin on.
Though, during holidays or special occiasions or When I am making mashed potatoes for a formal dinner or a gathering or a special occasion like thanksgiving or Christmas, I peel them.
If you are in the mood for something different, I suggest you try making Mashed Sweet Potatoes in the instant pot.

This is a no drain method of making mashed potatoes, which means, you skip another arduous step of straining the potatoes, before mashing them.
Yes..i am Lazy and i like to find shortcuts..lol..They are worth it! Especially on Thanksgiving or Christmas when you have a hundred other dishes to make.
