  • 5 pounds red potatoes
  • 8 ounces butter
  • 1-2 cups milk
  • 2 teaspoons salt this is a variable, and will be adjusted according to your taste preferences.
  • 1-3 tablespoons cajun seasoning
  • ½ teaspoon ground black pepper


  • Make sure and read all instructions thoroughly before starting.
  • Prepare potatoes. I like to wash, cut off the ends, and cut out any big eyes. If you prefer, you can also just peel the potatoes.
  • Quarter potatoes and place in a pan with enough water to cover them. Add in 2 teaspoons salt.
  • Turn heat on high and bring to a boil. Reduce the heat and continue to cook until the potatoes are tender. You don't want to overcook them, but get them to tender. I check by pricking with a fork.
  • Reserve ½ cup of the potato water, then drain the rest. Add the potatoes, butter (minus 1 tablespoon for topping), 1 cup of milk, 1 tablespoon cajun seasoning, and black pepper to a bowl.
  • With a hand mixer or stand mixer, mix on high until the potatoes are mashed, creamy, and whipped. Taste and adjust seasonings as needed. Our family likes it kind of salty and spicy, so I added another teaspoon of salt and another tablespoon of cajun seasoning.
  • Whip again and test again. Once the potatoes are done, plate, then top with the remaining pat of butter. Last, sprinkle with a little more cajun seasoning.
  • That is it, you are done!! Now, sit back and enjoy. You deserve it.


  • Probably the most important thing I can teach you about making these potatoes is to MAKE SURE YOU SALT THE WATER when you are boiling the potatoes. If there is one thing you do not want to forget, it is this.
  • This will give the potatoes a great subtle salty flavor you will not get by adding it in later. So, make sure the water is salted.
  • Next, if you are looking for potatoes that are creamy like mine, butter is key. Well, butter and milk.
  • I also really like to use a stand mixer or hand mixer for whipping these potatoes. My family and I love that texture so much better than if you use a potato masher. This is a personal choice though, you can mash them how you like.
  • If you want to prep your potatoes a day ahead, you can add them to really cold water and place them in the fridge. I put them in the pan I will be cooking them in for ease. The next day when you are ready, place on the cooktop, salt, and cook as directed.
