Ingredients

• 5 large Russet potatoes
• 8 tablespoons Butter
• 1 cup Heavy cream
• 1 cup Sour cream
• 1 teaspoon Garlic powder
• 1.5 teaspoons Salt
• 0.5 teaspoon Black pepper
• 2 cups Sharp cheddar cheese, shredded
• 0.5 cup Parmesan cheese, grated
• 2 tablespoons Fresh chives, chopped
• 0.5 cup Panko breadcrumbs
• 1 tablespoon Olive oil

Directions

Step 1

Peel and chop the russet potatoes into evenly sized chunks.

Step 2

Place the potatoes in a large pot of cold, salted water and bring to a boil. Cook until the potatoes are fork-tender, about 15-20 minutes.

Step 3

Drain the potatoes and transfer them back to the pot. Mash the potatoes until smooth using a potato masher or hand mixer.

Step 4

Mix in the butter, heavy cream, sour cream, garlic powder, salt, and black pepper. Stir until creamy and well combined.

Step 5

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

Step 6

Spread half of the mashed potato mixture into the prepared dish. Sprinkle 1 cup of shredded sharp cheddar cheese over the layer, then spread the remaining mashed potatoes on top.

Step 7

In a small bowl, combine the remaining 1 cup of cheddar cheese with the grated Parmesan cheese, Panko breadcrumbs, and olive oil. Mix well to create the topping.

Step 8

Sprinkle the topping evenly over the mashed potatoes in the casserole dish.

Step 9

Bake uncovered in the preheated oven for 25-30 minutes, or until the topping is golden brown and crispy.

Step 10

Remove from the oven and let cool for 5 minutes. Garnish with chopped chives before serving.
