You'll Love These Make-Ahead Mashed Potatoes

"Mashed-potato lovers, meet your new best friend: duchess potatoes. This decadent side is every bit as creamy, buttery, and fluffy as its stove-top counterpart, but has one outstanding difference: These spuds can be made completely in advance. (Seriously!) And while their name sounds fancy, these potatoes are a cinch to prepare. In fact, I think the hardest part about making this dish is waiting to eat it. Bring a little royalty to your holiday table and give this recipe a try!"

1. In a large pot, cover potatoes with cold salted water by 2 inches. Bring to a boil; reduce to a rapid simmer and cook until tender, 15 minutes. Drain in a colander, let sit 5 minutes, then return to pot. Add butter and, with a potato masher, mash until smooth. Season with salt and pepper. Add 2 egg yolks, 1/4 cup cream, and pinch of nutmeg; stir until combined.

2. Preheat oven to 450 degrees. Line a baking sheet with parchment and lightly butter paper. Dollop mixture in 8 equal portions on sheet, 2 inches apart. Using the back of a spoon, create a small well in the center of each. Freeze until firm, 15 minutes. Whisk together remaining egg yolk and 2 teaspoons cream. Brush on potatoes and bake until golden, 15 minutes.
