For extra flavor, sprinkle 1 cup crushed herb-seasoned croutons or shredded Parmesan cheese over mashed potatoes. Or place purchased basil pesto in a resealable plastic bag, snip off a tiny corner and drizzle pesto over potatoes.
Love garlic? Peel and finely chop 1 or 2 cloves and add to the potatoes before mashing in step 3.
Use a handheld potato masher for the fluffiest mashed potatoes. If using an electric mixer, do not mix too long; overmixing releases more starch from the potatoes and they can become gummy.
