Make-Ahead Mashed Potatoes

Begin by filling a large container with salted water and placing it on high heat, causing the water to reach its boiling point. Next, add the potatoes and cook until they have reached a tender yet still slightly firm state, which should take around 15 minutes. Remove the potatoes from the water and transfer them to a large serving dish.

Mash the cooked potatoes in a bowl until they have reached a smooth consistency. Then, add sour cream, cream cheese, butter, onion powder, salt, and pepper to the potatoes. Mix everything together until well combined. Cover the bowl with a lid or plastic wrap and refrigerate for at least 8 hours, or overnight.

Before baking the potatoes, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Lightly grease a medium-sized baking dish with butter or cooking spray to prevent the potatoes from sticking. Once the dish is prepared, transfer the chilled potato mixture into it.

Then, place the baking dish in the preheated oven and bake for about 30 minutes, or until the potatoes are golden brown and heated through. This should result in a deliciously creamy side dish.
