Using the Wrong Potato

For creamy, fluffymashed potatoes, use a potato high in starch.

The thick-skinned Russets absorb seasonings, butter, and cream better than any other potato.

Yukon Golds are also a good selection for mashed potatoes.

Red-skinned potatoes have low starch and absorb little water when cooked, so they remain firm and smooth.

Not Washing Your Potatoes Before Peeling

Washing your potatoes before you peel them is a must.

Potatoes are pulled out from the ground and carry dirt on them.

Keeping the water at a constant boil might cause the potatoes to lose their shape and get mushy.

This will allow any excess water to dry off, further preventing soggy, watery mashed potatoes.

Regardless of the technique, remember not to overwork the potatoes.

Warm the liquid in a saucepan on the stovetop or in a glass measuring cup in the microwave.

Or simply let your dairy stir-ins (sour cream, buttermilk, cream cheese, etc.)

come to room temperature before adding them to the potatoes.

Letting the Potatoes Get Cold

Proper planning is key.

If your mashed potatoes are done too soon, they could cool or dry out before the meal.

Start the potatoes during the last hour of cooking, when you start the gravy.
