Easy Make-Ahead Mashed Potatoes
My mama has been making these mashed potatoes for as long as I can remember (20+ years or so?). She serves this dish every year on Christmas Eve alongside her amazing prime rib and collard greens at our annual family gathering. It has always been one of my very favorite side dishes!
I asked Mama where she got this recipe and she told me she came across it in a magazine in a waiting room while waiting for an appointment several years ago. She puts her own personal spin on it and I’m here to share her convenient make-ahead potato deliciousness with you.
Your Simple Ingredients
- Potatoes – Russet or Yukon gold potatoes (Mama always uses russet).
- Cream cheese – Cubed cream cheese at room temperature.
- Sour cream
- Onion powder
- Garlic powder
- Salt and black pepper
- Butter – melted
- Chopped fresh chives or parsley – optional garnish
How to Prepare
Following is a very brief overview of how to prepare; please see the recipe card for full detailed instructions.
- Gently boil potatoes that have been peeled and cut into approximately 1 inch pieces until fork-tender (but not falling apart). Drain in a colander and return to pot.
- Mash potatoes (using a potato masher) with cubed cream cheese.
- Add sour cream and seasonings and mash until combined and desired consistency is met.
- Transfer to a 13 x 9 baking dish that has been greased with butter.
- Allow to cool to room temperature, then cover with foil and refrigerate overnight (or up to 2 days).
- When ready to bake, remove from fridge 30 minutes prior to baking.
- Bake (covered with foil) in a preheated oven for 50 minutes. Remove foil and bake an additional 5 to 10 minutes, or until heated through.
- Top with melted butter before serving.
If you prefer your potatoes smoother and fluffier, feel free to use a hand mixer to beat until your desired consistency is reached.
