Make-Ahead Mashed Potatoes

Instructions

1. 01

   Place peeled, cut potatoes in a large saucepan, cover with cold water to an inch above the potatoes. Add 2 teaspoons of salt to the water. Add the garlic cloves and rosemary sprig. Heat on high to bring to a boil, then reduce to low, cover to maintain a simmer until the potatoes are just cooked through, about 10 to 12 minutes. Once potatoes are done, drain the potatoes. Discard the rosemary sprig, save the garlic cloves with the potatoes.

2. 02

   While the potatoes are still hot, use either a potato masher or a potato ricer to roughly mash the potatoes and the garlic cloves in a large bowl. A ricer will yield fluffier, less gluey, mashed potatoes.

3. 03

   In a large upright mixer (or if you have strong arms, you can do this by hand), add the riced or roughly mashed potatoes into the mixer bowl, along with 2 tablespoons of butter, the softened cream cheese, and the yogurt. Mix on low to start, then increase the speed to medium and mix just until everything is well incorporated. (Don't overmix!) Stir in the minced rosemary, salt and pepper. Taste and add more salt and pepper if needed.

4. 04

   Butter generously the inside of a 2-quart casserole dish. Add the mashed potatoes, and spread out in an even layer. Dot with the remaining 1 tablespoon of butter. At this point, you've done the make-ahead part of the recipe. You can cover with plastic wrap and chill until ready to bake. You can make up to 2 days ahead. (Or you can freeze for up to 2 weeks ahead; see headnotes for more detailed freezing and reheating instructions.)

5. 05

   When ready to make, remove from refrigerator and let sit for an hour to come to room temperature. Bake at 350°F for 30 to 45 minutes, until the top is lightly browned. Did you love the recipe? Give us some stars and leave a comment below!
