Ingredients

• 3 large Russet potatoes
• 3 large Sweet potatoes
• 6 tablespoons Butter
• 0.5 cups Heavy cream
• 2 teaspoons Salt
• 1 teaspoon Black pepper
• 1 teaspoon Garlic powder
• 1 cup Breadcrumbs
• 0.5 cups Parmesan cheese
• 1 cup Cheddar cheese
• 2 tablespoons Olive oil
• 2 tablespoons Fresh parsley

Directions

Step 1

Peel and chop the russet potatoes and sweet potatoes into roughly 1-inch cubes.

Step 2

Place the potatoes and sweet potatoes in a large pot and cover them with cold water. Add a pinch of salt to the water.

Step 3

Bring the pot to a boil over medium-high heat, then reduce the heat to a simmer. Cook the potatoes for 15-20 minutes, or until they are fork-tender.

Step 4

Drain the potatoes in a colander and return them to the pot. Add 4 tablespoons of butter, heavy cream, salt, black pepper, and garlic powder.

Step 5

Using a potato masher or an electric hand mixer, mash the potatoes until smooth and well combined. Adjust seasoning to taste if necessary.

Step 6

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with 1 tablespoon of butter.

Step 7

Spread the mashed potato and sweet potato mixture evenly into the casserole dish, smoothing the top with a spatula.

Step 8

In a small mixing bowl, combine breadcrumbs, Parmesan cheese, olive oil, and chopped fresh parsley. Mix until the crumbs are evenly coated.

Step 9

Sprinkle the breadcrumb mixture evenly over the top of the potato layer in the casserole dish.

Step 10

Follow with an even layer of shredded cheddar cheese on top of the breadcrumbs for an additional cheesy topping.

Step 11

Place the casserole dish on the center rack of the preheated oven and bake for 25-30 minutes, or until the topping is golden brown and crispy.

Step 12

Let the casserole cool for 5 minutes before serving. Garnish with additional parsley if desired.
