Select about 3 pounds of potatoes. Russet potatoes are excellent for a fluffy texture, while Yukon Gold potatoes bring a buttery richness.
Peel the potatoes and cut them into evenly sized chunks. This ensures even cooking and makes mashing a breeze.
Place the potato chunks in a pot, cover them with cold water, and add a generous pinch of salt. Bring the water to a boil and let the potatoes simmer until they're fork-tender – usually 15-20 minutes.
Drain the potatoes and let them sit in the pot for a minute to evaporate excess moisture. This helps achieve a creamier texture.
Using a potato masher or a fork, start mashing the potatoes. Don't worry about perfection; a few lumps add character.
Throw in about 1/2 cup of butter.
In a separate bowl, heat up about 1 cup of milk in the microwave. Warm milk blends better, creating a smoother texture. Add the warmed milk gradually to the potatoes, mixing as you go until you achieve the desired creaminess.
Mix in additional salt and the minced garlic.
Give your mashed potatoes a taste and adjust the seasonings if needed.
