Savory Herb Mashed Potatoes

Why This Savory Herb Mashed Potatoes Works

As the potatoes boil, the cubes soak up water and their starch swells. After about 15 minutes they are soft all the way through, so they mash easily instead of staying chunky or gluey. Draining them and putting them back in the warm pot lets a little extra steam escape, so the potatoes stay fluffy and not watery.

In the small pan, butter and garlic warm together. The garlic softens and loses its sharp bite, and the melted butter spreads it evenly later. When the heavy cream goes in and heats up, the fat and liquid mix smoothly with the butter. Pouring this warm mixture into the hot potatoes means the starch in the potatoes grabs onto the fat and cream and turns everything thick and creamy instead of thin.

Once the herbs, salt, pepper, and Parmesan are stirred in, the soft potatoes hold them in place. The cheese melts into the warm mash and slightly tightens it, so the potatoes stay rich, smooth, and not runny.

Mistakes To Avoid

Boiling the potatoes until they are falling apart in the water makes them waterlogged. Extra water gets trapped inside the pieces, so when they are mashed, the potatoes turn pasty and loose instead of fluffy and creamy.

Cutting the potato cubes in very different sizes causes uneven cooking. Smaller pieces turn mushy while the bigger chunks stay a bit firm, so the mash ends up with random hard bits that never fully smooth out.

Pouring in all the hot cream and butter at once often leads to gluey potatoes. The starch gets worked too hard while trying to mix in that much liquid, and the mash turns heavy and stretchy instead of light.

Using an electric mixer on high speed beats the potatoes too much. The starch breaks down and tightens up, and the final bowl looks shiny and elastic instead of soft and spoonable.

Adding the Parmesan while the potatoes are barely warm leaves little chewy pieces of cheese. The cheese doesn’t melt in properly, so the mash has grainy, uneven spots instead of a smooth texture.
