How this guide works: Ingredients are broken down into approximate location in the grocery store, by order that you'd usually purchase them. There is also a cost of ingredients scale ranging from $ (very cheap) to $$$$ (extremely expensive - I'm not sure any of my recipes even have an ingredient like this yet). 

About Millennial Staples: These are items you should always keep stocked in your fridge, freezer, or pantry. It will make throwing together a quick dinner easy and simplify grocery shopping. It allows you to purchase food on sale, and all these items are extremely unlikely to go bad before you use them!

From Your Pantry

  • Salt
  • Water


  • 1 - 5 lb. bag russet potatoes $ Russets are the best bet for mashed potatoes - they'll come out smooth and creamy.


  • 1 - 8oz. package of cream cheese $ Cream cheese is one of my secret ingredients in cooking. It makes these mashed potatoes extra creamy.
  • 1-2 cups milk $ Any kind of milk will work - the fattier, the better of course. I use 2% in my regular everyday cooking so I used that in my recipe. You can also use heavy cream if you're looking for some extra indulgent mashed potatoes. The amount of milk depends on how dry or wet you prefer your mashed potatoes.
  • 1 stick of butter $ We keep unsalted butter in our house for baking, so if you use unsalted, be aware you'll need to adjust the salt content (to your preference) when adding in salt at the end. If you use salted butter, be sure to taste your potatoes before adding any additional salt. And I don't wanna hear it about the whole stick - YES, you NEED the whole stick.
