Ingredients

• 5 pounds (about 2.3 kg) Yukon Gold or Russet potatoes, peeled and cut into chunks
• 1/2 cup (120ml) unsalted butter, softened
• 8 ounces (225g) cream cheese, softened
• 1 cup (240ml) sour cream
• 1/2 cup (120ml) milk, warmed
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon salt (or to taste)
• 1/2 teaspoon black pepper
• 1 1/2 cups (150g) shredded cheddar cheese, divided
• 1/4 cup (60ml) grated Parmesan cheese
• 2 tablespoons fresh chives, chopped (optional, for garnish)

Instructions

1. Cook the Potatoes:

1. Place the potato chunks in a large pot and cover with cold water. Add a pinch of salt.
2. Bring to a boil over medium-high heat and cook until the potatoes are tender, about 15-20 minutes. Drain well.

2. Mash the Potatoes:

1. Return the drained potatoes to the pot or a large mixing bowl.
2. Add the softened butter, cream cheese, sour cream, warm milk, garlic powder, onion powder, salt, and pepper.
3. Mash until smooth and creamy (use a hand masher, electric mixer, or ricer). Adjust seasoning to taste.

3. Assemble the Casserole:

1. Preheat your oven to 350°F (175°C) if baking immediately.
2. Transfer the mashed potatoes to a greased 9×13-inch (23x33cm) baking dish. Spread evenly.
3. Sprinkle 1 cup of shredded cheddar cheese evenly over the top.

4. Make-Ahead Option:

• Cover the dish tightly with plastic wrap or foil and refrigerate for up to 24 hours.

5. Bake:

1. If baking right away, bake uncovered for 30-35 minutes, until the cheese is melted and bubbly.
2. If baking from refrigerated, let the casserole sit at room temperature for 20 minutes, then bake at 350°F (175°C) for 40-45 minutes.

6. Add Final Touches:

1. Sprinkle the remaining 1/2 cup of cheddar cheese and Parmesan cheese on top. Bake for an additional 5-10 minutes until golden and melted.
2. Garnish with fresh chives before serving.

Tips

• Add Mix-ins: Crumbled cooked bacon, caramelized onions, or sautéed mushrooms make great additions.
• Texture Preference: For chunkier mashed potatoes, mash less thoroughly. For smoother potatoes, use a ricer.
• Freezing Option: Assemble the casserole without cheese topping and freeze for up to 2 months. Thaw overnight in the fridge before baking.

This mashed potato casserole is rich, creamy, and always a crowd-pleaser. Perfect for potlucks, family dinners, or as a Thanksgiving side dish. Enjoy! 🥔🧀
