Make Ahead Mashed Potatoes

Make ahead mashed potatoes have been a lifesaver for me on more than one occasion. I first learned about this recipe for make-ahead mashed potatoes from a friend at church one spring. I had invited several people to come to the church on Easter Sunday to watch the children’s program that my children were participating in, and invited them to joint us for dinner at my house afterwards.

It was after I confirmed the final guest would be coming when I had a horrible revelation. I realized that I was preparing dinner for 11 people that I realized I wasn’t going to be home in the morning to prepare it. I was panicked, and began my first search for easy make ahead recipes that could help me to have appetizers ready when my guests arrived, and to get dinner on the table quickly.

It was during a conversation with my friend about this problem, that she told me about this recipe for make ahead mashed potatoes. We made them, they were wonderful, and we loved them. In fact, these are the mashed potatoes that I make for most holiday meals, but I have a confession. Sometimes, I don’t make them ahead. Instead, I make them and we eat them right away.

Drain them, then return them to the pot.

Add everything else to the pot and mash it all together until it’s a smooth consistency. You can use a potato masher, a mixer, or my favorite, the immersion blender.

Once everything is combined, scrape everything into a medium sized casserole dish, cover it, and put it into the refrigerator for a day or two until you’re ready to bake it.

If you want, put them into a freezer to oven safe pan and cover them and stick into the freezer for up to a month. If you’re like me, you may just make them and eat them on the same day, but it’s nice to know you can make them ahead of time if you need to.
