I love the "tang" that you get with buttermilk, but you can substitute with regular creamor whole milk if you don't have buttermilk on hand.
Garlic Red Mashed Potatoes: add a dash of garlic powder to the potatoes for an extra dose of flavor.
Garnish with chopped fresh chives, green onions, or parsley for a bright, fresh finish to the dish!
If you don't have a potato masher, you can use a fork to mash the potatoes or grab an electric hand mixer.
To Reheat Skin-On Mashed Red Potatoes: For best results, skip the microwave (which tends to suck the moisture out of your potatoes), and instead use the oven to reheat the mashed potatoes. Place the mashed red potatoes in an oven-safe dish. Stir in about 1/2 cup of buttermilk (or other liquid) and an extra pat or two of butter. Reheat in a 350 degree F oven (uncovered) just until warmed through (about 20-30 minutes).
