How to Make the Best Creamy Buttermilk Ranch Mashed Potatoes Recipe

Can you make mashed potatoes using buttermilk? Yes, you can! This variation on mashed potatoes has a bit of a twang from the buttermilk that gives them a taste that’s bright and fresh. They’re easy enough for everyday meals, yet special enough to be served for any special occasion.

  • Ingredients you’ll need to make homemade Creamy Buttermilk Mashed Potatoes: 12 medium russet potatoes peeled and cubed, garlic salt, butter, chive and onion cream cheese, dry Ranch dressing mix, buttermilk and fresh chives for garnishing.
  • Kitchen gadgets you’ll need: A sharp knife and cutting board, vegetable peeler, hand mixer or a potato masher, measuring cups and spoons and a large pot for cooking the potatoes.
  • You could also use Yukon Gold potatoes, white potatoes or red potatoes for this mashed potatoes recipe. Russet potatoes work best.
  • It’s important to start with cold water to boil the potatoes. Cover them leaving around 1-2 inches of head space.
  • Don’t forget to salt the water. In this instance of these buttermilk mashed potatoes, I’m using garlic salt to infuse the potatoes with more flavor.
  • Simmer the potatoes just until fork tender. They shouldn’t break into tiny pieces or be too mushy. Test the centers with the point of a sharp knife or the tines of a fork. Cooking time may vary slightly depending on the size of the potato chunks.
  • Drain the cooked potatoes well. Unlike pasta cooking liquid, the water from boiling potatoes may cause the mashed potatoes to break down.
  • Each variety of potatoes contains different levels of starch content and will cook slightly differently. Adjust the boiling time as needed to adapt.
  • The dry Ranch dressing salad dressing mix is easy to find. If you buy a bulk container, you’ll need around 2 generous tablespoons.
  • If you prefer, light cream or half and half can be used in the same amount as buttermilk in this easy mashed potatoes recipe.
  • You can also make your own buttermilk. To each one cup of whole milk add 1 tablespoon of fresh lemon juice or white distilled vinegar. Let stand for 5 minutes, then stir and proceed with the recipe.
  • You can also use sour cream in place of buttermilk for this recipe.
  • These potatoes can be made one day in advance, then gently reheated in a double boiler until heated through before serving.
  • Store leftover Buttermilk Ranch Mashed Potatoes chilled in the refrigerator for up to 3 days.
