Ingredients

• 6 medium russet potatoes
• 4 tablespoons unsalted butter
• 1 medium yellow onion, finely diced
• 2 cloves garlic, minced
• 1.5 cups sour cream
• 8 ounces cream cheese, softened
• 2 cups shredded sharp cheddar cheese
• 0.5 cup whole milk
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 teaspoon paprika
• 1 cup panko breadcrumbs
• 0.5 cup parmesan cheese, grated
• 2 tablespoons fresh parsley, chopped (optional garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Peel the russet potatoes and cut them into chunks. Place the potatoes in a large pot, cover with water, and bring to a boil. Cook for about 15-20 minutes, or until the potatoes are fork-tender. Drain the potatoes well.

Step 3

While the potatoes are cooking, melt 2 tablespoons of the butter in a skillet over medium heat. Add the diced onion and sauté until soft and translucent, about 5-7 minutes. Stir in the minced garlic and cook for an additional 30 seconds. Remove from heat and set aside.

Step 4

In a large mixing bowl, combine the cooked potatoes, sour cream, cream cheese, 1 cup of shredded cheddar cheese, and milk. Mash the mixture until creamy and smooth.

Step 5

Stir the sautéed onion and garlic into the potato mixture, then add salt, black pepper, and paprika. Mix until evenly combined.

Step 6

Transfer the potato mixture to a greased 9x13-inch casserole dish. Spread it out evenly.

Step 7

In a separate small bowl, combine the panko breadcrumbs, grated Parmesan cheese, and the remaining 2 tablespoons of melted butter. Sprinkle this mixture evenly over the top of the casserole.

Step 8

Sprinkle the remaining 1 cup of shredded cheddar cheese over the breadcrumb topping.

Step 9

Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbling.

Step 10

Remove the casserole from the oven and let it cool for 5 minutes. Garnish with chopped parsley, if desired, and serve warm.
