Ingredients

  • 5 lbs russet potatoes - peeled and sliced into 1" pieces (6-7 large potatoes)
  • 2 ½ teaspoons sea salt
  • ½ teaspoon black pepper
  • ½ cup salted butter
  • 1 ½ cups heavy cream - heated (whipping cream or half and half)
  • 8 ounces cream cheese (optional)

Instructions

  • In a large pot, fill ½ way with cold water and add ½ teaspoon sea salt.
  • Peel and slice the potatoes into 1" pieces. Put the cut potato pieces into the large pot of water as you peel and slice so they don't turn brown.
  • Be sure water covers the potatoes by 2 inches, bring to a boil on medium-high heat.
  • Cook the potatoes for 25 minutes or until the potatoes are soft and fork tender. They should easily break apart by smashing a piece with a fork on a small plate.
  • Once cooked, drain well in a colander to remove the extra liquid. Discard the water.
  • Hold the potato ricer over a large empty pot, and load the ricer full in batches using a large spoon, and press all the potato pieces into the same large pot. Or, place your drained potatoes back in the pot once drained and mash with a potato masher. If you want airy fluffy creamy mashed potatoes, the ricer really works!
    Again, the masher will work, but it never gets all the little lumps out completely. Whichever way you mash your potatoes, the most important thing is to get them mashed well before adding the cream and butter mixture for a smooth creamy texture.
  • In a small sauce pan, add the butter, heavy cream, salt, and pepper. Stir and don't boil, once those ingredients are melted together you can add the cream cheese if you desire. It makes the mashed potatoes super creamy!
  • Pour the creamy butter sauce all over the well mashed potatoes, and mix well with a large spatula.
  • Spray an oven-safe casserole dish with nonstick spray (for easier cleanup), transfer the creamy potatoes in and cover with the lid of the dish or a large piece of aluminum foil. Keep in a warm oven or place in the refrigerator until ready to reheat for up to 2 days.

5 Ways to reheat and keep mashed potatoes warm

  • Reheat in the microwave: Put the cold potatoes in a microwave-safe dish, add a splash of liquid like milk or cream, and gently stir. Then heat at half power for 2-3 minutes. Time will depend on how big a dish of potatoes you are warming up.
    Reheat in the oven: cover mashed potatoes with foil and reheat at 375 for 30-40 minutes.
  • Reheat in a slow cooker on medium low, add them to your slow cooker and mix in a little more cream and butter to keep them moist. Stir every 15 minutes until hot. Keep the temperature on low setting.
  • Place in a double gallon zip lock bag (put one inside of the other), seal well and place carefully in a pan of water on low simmer.
  • Place mashed potatoes in a heat-safe bowl over a pot of water to reheat and keep warm on the stove.
  • Reheat the potatoes in a method you choose and keep hot on an electric warming tray or a heating pad covered with a pretty towel. This works great for holidays and parties, or family dinner.

Notes

Potato Ricer

Presses the potatoes through a screen with holes and creates a smooth consistency with no lumps. If you really want airy fluffy mashed potatoes, the ricer is the way to go. A masher or mixer will work, but it never gets all the little lumps out completely. 

Heavy Cream

 You can use any dairy product; heavy cream, half and half, whipping cream, or heavy whipping cream. Even hot milk works fine if that is what you have in a pinch. Add a little extra cream or additional milk ¼ cup at a time, give a good stir, then see if is the creamy texture you want.

Mashed Potato Top Tips

    • Food processors and hand mixers, can't get all the lumps out and make them a gummy texture in my experience. Not smooth and fluffy like an inexpensive ricer can.
    • Never mix lumpy potatoes with more cream or butter, it becomes almost impossible to get the lumps out at that stage!
    • Never use potato flakes and expect the best flavor and texture. Good quality ingredients are always worth it.

Flavor Variations And Additions

There are lots of garlic fans out there that love roasted garlic or garlic powder in their mashed potatoes. You can also mix in some onion powder for extra flavor.
Chicken Stock: Some people cook their potatoes in Chicken Stock, I find using water is fine but some people love this method to add flavor.

Mashed Potato Toppings

So many people love a make-ahead gravy or even a giblet gravy to ladle on hot potatoes, but you can add grated parmesan cheese, cheddar cheese, sour cream, extra butter, or a sprinkle of green onions. I really love homemade Herb Butter, try my recipe!
