Baked Marbled Mashed Potatoes

Mashed potatoes and mashed sweet potatoes marbled together in a savory hot dish topped with a crunchy bread crumb topping. I was first served this dish at a holiday dinner and begged the hostess for the recipe. It is a rich and delicious way to serve two favorite potatoes in a single dish. It tastes wonderful and presents well. Your guests will rave over this one.

Ingredients

• ½ teaspoon salt
• 1 cup sour cream
• ⅛ teaspoon ground nutmeg
• 1 cup heavy cream
• ½ cup dry bread crumbs
• ¼ cup salted butter
• ¼ cup minced fresh parsley
• 1 ½ pounds medium baking potatoes, peeled and quartered
• 3 large sweet potatoes, peeled and quartered
• 4 large shallots, minced
• ¼ teaspoon ground white pepper, or to taste
• 6 tablespoons salted butter, melted

Recipe Instructions

Step 1

Preheat the oven to 350 degrees F (175 degrees C).

Step 2

Place white potatoes in a large pot and cover with salted water. Place sweet potatoes in a second pot and cover with salted water. Bring both pots to a boil. Reduce heat to medium-low and simmer, uncovered, until tender, about 25 minutes. Drain and set aside to cool in 2 separate bowls.

Step 3

While potatoes are cooling, melt butter in a small pan over medium heat. Add shallots and cook until tender, about 5 minutes. Remove from the heat.

Step 4

Mash potatoes with a potato masher or ricer.

Step 5

Beat cream in a chilled glass or metal bowl with an electric mixer until soft peaks form. Whisk sour cream into whipped cream.

Step 6

Stir 1/2 of the shallot mixture into each bowl then gently fold in. Gently fold 1/2 of the cream mixture into each bowl. Divide salt, pepper, and nutmeg evenly between the two bowls. Taste and adjust seasoning.

Step 7

Place 1/2 of the sweet potato mixture in a 2-quart baking dish. Layer 1/2 of the white potato mixture on top. Repeat layers once more, then swirl with a spatula to create a marbled effect.

Step 8

Mix melted butter, bread crumbs, and parsley for topping together. Sprinkle topping mixture over potatoes.

Step 9

Bake in the preheated oven until topping is golden brown and potatoes are hot all the way through, 30 to 35 minutes.
