Ingredients

• 4 large russet potatoes
• 6 tablespoons unsalted butter
• 1 cup whole milk
• 1 cup sour cream
• 4 ounces cream cheese
• 1.5 cups shredded sharp cheddar cheese
• 1 teaspoon garlic powder
• 2 teaspoons salt
• 1 teaspoon black pepper
• 2 tablespoons green onions (optional, for garnish)
• 0.5 cup panko breadcrumbs
• 1 tablespoon olive oil

Directions

Step 1

Peel and chop the potatoes into large chunks. Add them to a large pot of salted water and bring to a boil over medium-high heat.

Step 2

Reduce the heat and let the potatoes simmer until tender, about 15-20 minutes. Check doneness by piercing a potato chunk with a fork—it should slide in easily.

Step 3

Drain the potatoes and return them to the pot. Add 4 tablespoons of butter, milk, sour cream, and cream cheese to the potatoes. Use a potato masher to mash everything together until creamy and smooth.

Step 4

Mix in garlic powder, salt, and pepper. Adjust seasoning to taste.

Step 5

Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish with butter or nonstick spray.

Step 6

Spread the mashed potato mixture evenly into the casserole dish. Sprinkle shredded cheddar cheese evenly on top.

Step 7

In a small bowl, combine panko breadcrumbs with olive oil. Toss until the breadcrumbs are lightly coated. Sprinkle the breadcrumbs over the cheese layer.

Step 8

Bake the casserole in the preheated oven for 20-25 minutes or until the cheese is melted and the breadcrumbs are golden brown.

Step 9

Remove from the oven and let it rest for 5 minutes before serving. Garnish with chopped green onions, if desired.

Step 10

Serve warm and enjoy!
