Cooking Instructions:
Preheat your oven to 375°F (190°C). Begin by peeling the potatoes and cutting them into evenly sized chunks for even cooking.
Place the potato chunks in a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil and cook until the potatoes are fork-tender, about 15-20 minutes.
Drain the cooked potatoes and return them to the pot. Add the butter, heavy cream, and sour cream. Mash the potatoes using a potato masher or a fork until smooth and creamy.
Season the mashed potatoes with salt and black pepper to taste. If desired, fold in the chopped chives for added flavor and color.
Transfer the mashed potatoes to a greased baking dish and smooth the top with a spatula. Place the dish in the preheated oven and bake for 20-25 minutes, or until the top is lightly golden and crispy.
For the best results, use starchy potatoes like Yukon Gold or Russet, as they yield the fluffiest mash. You can also experiment with adding roasted garlic or cheese for an extra flavor boost.
If you're making these ahead of time, simply prepare the mashed potatoes, store them in the refrigerator, and reheat in the oven just before serving. This dish is versatile and can be tailored to your taste!
