What’s the best way to cook potatoes for mashed potatoes?

Bring a pot of salted water to a boil. Add peeled potatoes, and cook until tender but still firm, about 15 minutes; drain. Mash, and continue with the instructions for this recipe.

How to prepare Make Ahead Mashed Potatoes:

Start with already cooked potatoes that are mashed.  Add cream cheese, sour cream and milk.  This is going to make your mashed potatoes creamy, and they won’t dry out when you’re making them ahead!  Onion salt and pepper are added for a little flavor.

If serving right away, cover and bake in a preheated oven at 325°F. for 50 minutes.  However, you can make this recipe up to several days ahead and store in the fridge. If baking cold, let stand at room temperature for 30 minutes first.  Add melted butter on top and maybe some chopped chives!
