Ingredients

• 4 large Russet potatoes
• 6 tablespoons Unsalted butter
• 1 cup Milk
• 1 cup Sour cream
• 1.5 teaspoons Salt
• 0.5 teaspoons Black pepper
• 1 teaspoon Garlic powder
• 2 cups Cheddar cheese (shredded)
• 0.5 cups Parmesan cheese (grated)
• 1 cup Panko breadcrumbs
• 1 tablespoon Olive oil
• 2 tablespoons Fresh parsley (chopped)

Directions

Step 1

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

Step 2

Peel the potatoes and cut them into evenly sized chunks. Place the potato chunks in a large pot and cover them with cold water.

Step 3

Bring the pot of water to a boil over medium-high heat. Reduce the heat to a simmer and cook the potatoes for about 15-20 minutes, or until they are fork-tender.

Step 4

Drain the cooked potatoes and return them to the pot. Add the butter, milk, sour cream, salt, pepper, and garlic powder.

Step 5

Mash the potatoes with a potato masher or use an electric mixer until they are smooth and creamy. Adjust the seasoning to taste, if needed.

Step 6

Fold in 1.5 cups of shredded cheddar cheese and the grated Parmesan cheese until evenly incorporated.

Step 7

Transfer the mashed potatoes into the prepared casserole dish, spreading them out evenly.

Step 8

In a small bowl, combine the panko breadcrumbs with olive oil and mix until the breadcrumbs are evenly coated. Sprinkle this mixture over the top of the mashed potatoes.

Step 9

Sprinkle the remaining 0.5 cup of shredded cheddar cheese over the breadcrumb topping.

Step 10

Bake the casserole in the preheated oven for 20-25 minutes, or until the top is golden brown and crispy.

Step 11

Remove the casserole from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley before serving.
