Mashed potatoes. Come on, who needs a recipe for mashed potatoes? You cook the spuds, add some butter and milk (and sour cream and cheese, if you’re feeling indulgent), and season with salt and pepper. What’s to know?
A lot, according to my latest copy of Cook’s Illustrated. I was reading the article about a French apple tart (looks beautiful, but I think it will take all day just to slice the apples for it!) when I noticed the recipe on the preceding page: Parmesan Garlic Mashed Potatoes. The potato recipe looked significantly less involved than the tart recipe, plus, I had everything to make it. On the menu it went!
It goes without saying that since it’s a Cook’s Illustrated recipe, it’s more involved than your standard potato recipe. I did question some things in the recipe (such as why I have to cut the butter into chunks when I’m melting it anyway…), but since CI has tested for practically every scenario, I stuck to the recipe. For the most part, anyway. I saw no reason to pour the melted butter, garlic and Parmesan cheese from the saucepan into a separate bowl before then pouring it into the potatoes. They may have a dedicated dish crew, but I am not that lucky. 🙂 (I do appreciate all of the testing and science behind their recipes though. I definitely learn something from each issue – even if I don’t get around to making all of the recipes.)
Extra steps or not, it was worth it. The recipe says it feeds 4-6 people as a side dish, but I could have skipped the rest of dinner and just had potatoes. I hoarded the leftovers. (Sorry to all of my coworkers for making the office smell like garlic!) I licked the spatula and the potato masher clean. (OK, so I do that anytime I make mashed potatoes… let’s not get hung up on the details…) If I were making the potatoes for Thanksgiving, these would definitely be on my short list. But since I’m not in charge of the spuds (to my knowledge, anyway), I’ll just make these for other special occasions. You know, like Tuesday dinners. 😀
Parmesan Garlic Mashed Potatoes
2 pounds potatoes, peeled and sliced into 1/2″ thick chunks (CI recommends Yukon Golds; I just used the white potatoes from my Grandma.)
4 tablespoons unsalted butter, cut into 4 pieces
1/2 teaspoon garlic powder, mixed with 1/2 teaspoon water
1 1/4 teaspoons garlic, zested/minced into a paste, divided
2/3 cup warm milk
1 1/2 ounces (3/4 cup) freshly grated Parmesan cheese
salt and pepper
parsley, for garnish (optional)
Place the potatoes in a large saucepan and add water until potatoes are covered with 1″ of water. Bring to a boil over medium heat, then reduce to a simmer and cook until potatoes are tender (about 15 minutes) and pierce easily with a paring knife. Remove from heat and drain the potatoes.
Meanwhile, melt the butter in a small saucepan over medium-low heat. Add the garlic powder/water mixture and 1 teaspoon of minced garlic to the butter and cook, stirring constantly, until the garlic is fragrant, about 1 minute. Remove the pan from the heat. Stir in Parmesan cheese, the remaining 1/4 teaspoon of garlic and 1/2 teaspoon freshly ground pepper.
Place the potato saucepan back on the stove over low heat. Add the potatoes to the pot and mash them. (Cook’s Illustrated recommends using a potato rice, but since I don’t own one, I just used my hand masher.) Stir the butter-Parmesan mixture into the mashed potatoes. Pour the milk into the potatoes and stir until combined. Taste the potatoes and season with salt, if necessary. (I added a scant 1/2 teaspoon to the mixture… significantly less than the 1 1/4 teaspoons that CI recommended.) Transfer the potatoes to a serving dish and top with parsley, if using. Serve immediately. (Unless the rest of your dinner isn’t ready yet. If that’s the case, simply cover the potatoes with foil and place in a warm oven.)
