Fluffy Buttermilk-Mashed Potatoes Recipe (2024)

FAQs

Why do you put buttermilk in mashed potatoes? ›

Dr. Potato of the Idaho Potato Commission says buttermilk can make mashed potatoes creamier than milk, bringing out a more tangy flavor thanks to the higher lactic acid found in buttermilk. Using buttermilk gives "impossibly fluffy" when mashed potatoes combined with baking soda.

Buttermilk mashed potatoes have the same consistency as traditional mashed potatoes. Buttermilk is substituted for the typical milk, half and half, or heavy cream. Buttermilk lends them a slight tang while keeping the overall dish a tad bit lighter, due to its lower fat content.

Removing the potato starch both before and after cooking ensures fluffy, not gluey, mashed potatoes. Milk and butter give the potatoes richness.

Ricer or Colander

Start as you would any mashed potato recipe—by boiling the potatoes until tender—then allow them to cool before adding them to a ricer. "If you rice them right away, you're not allowing excess moisture to evaporate off the potatoes," Greg says. Skipping this step can lead to dense, gluey potatoes.

Sour Cream: The sour cream helps keep the mashed potatoes fluffy. Cream Cheese: This adds a bit of creaminess without being too overpowering. Heavy Cream: Increases the creaminess and helps thin out the potatoes a bit.

Heavy Cream - While you, hypothetically, could use whole milk or something, I don't recommend it. Part of what makes these the creamiest mashed potatoes is the CREAM! Use the cream, we aren't eating mashed potatoes for our health. Sour Cream - This recipe is rich and it needs some tanginess for balance.

Buttermilk has more acid than regular milk, which will reduce the carbon dioxide released and thwart the leavening process important to these recipes. To achieve the desired result when using buttermilk instead of milk, be sure to substitute baking soda for some or all for of the baking powder.

Tip: To substitute buttermilk for milk in a recipe, use 2 teaspoons less baking powder and 1/2 teaspoon more baking soda than called for in the recipe for every cup of buttermilk used. Baking with Sour Cream: The creamy texture of sour cream makes baked goods more moist than if you used milk.

You can substitute buttermilk for regular milk in just about any baking recipe, cup for cup - but some experts advise making sure the recipe includes at least ½ teaspoon baking soda per cup of buttermilk.

The secret ingredient is just ice-cold water.

You soak the potatoes in iced water before they are cooked. This eliminates much of the starches in the potatoes, resulting in a super light and fluffy mash. It's also like when you make rice.

The Mistake: Using the Wrong Kind of Potato

Thick-skinned varieties like russets will give you the fluffiest results. Steer clear of waxy red-skinned potatoes, which turn gluey when mashed.

Once boiling, reduce heat, adjusting as needed to maintain a simmer. Cook potatoes until they offer no resistance when pierced: 10–12 minutes for baby potatoes, 15–20 minutes for small potatoes, or 30–40 minutes for large cubed potatoes. Drain potatoes in a colander and let cool 10 minutes.

The most likely cause of your problem is that you are overcooking the potatoes. Overcooking will cause the potatoes to break down too much, giving you a gluey texture which you will notice more when your mashed potatoes are cooler.

Just a pinch of baking soda is all you need to create mashed potatoes as soft as clouds. When you add baking soda, it reacts with the heat of the dish and the acid in the milk or cream to create small air pockets throughout the mash. These air bubbles translate to light and airy bites. Yum!

Instead of regular milk, pro chefs generally use a generous helping of buttermilk and plenty of half-and-half or (even better) heavy cream in their potatoes. If you think the bartenders up front are pouring heavy, they've got nothing on the cooks in the back who are in charge of the mashed potatoes.

Buttermilk is a versatile ingredient that can add lift to baked goods for the fluffiest pancakes, waffles, and biscuits, tenderize chicken and other proteins, give rich texture and tangy flavor to dressings, and shine in delicate desserts like buttermilk panna cotta.

Buttermilk is made up of a variety of acids – the results of the fermentation process, which give baked goods a couple of benefits. First, the acidity provides tangy flavor to balance all kinds of sweet baked treats. Second, it activates baking soda, producing the gas that makes dough or batter rise.

Garnish With Herbs

Speaking of delicious green things, both woody herbs like sage, rosemary, and thyme, and leafy herbs like dill can add freshness to this starchy side. A herb-based sauce like pesto swirled into mashed potatoes is another way to add vibrant flavor.
