Ingredients

• 4 medium Russet potatoes
• 6 tablespoons Unsalted butter
• 1 cup Whole milk
• 1 cup Sour cream
• 2 cups Shredded sharp cheddar cheese
• 1 cup Cooked bacon
• 4 stalks Scallions (green onions)
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Garlic powder
• 0.5 cup Parmesan cheese (optional)
• 1 as needed Nonstick cooking spray

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a medium-sized casserole dish with nonstick cooking spray and set it aside.

Step 2

Peel the potatoes and cut them into large chunks. Place the potatoes in a large pot and cover them with cold water. Add a pinch of salt and bring the water to a boil over medium-high heat. Cook the potatoes until fork-tender, about 15-20 minutes.

Step 3

While the potatoes are cooking, chop the cooked bacon into small pieces and thinly slice the scallions. Set them aside.

Step 4

Drain the cooked potatoes and return them to the pot. Add the butter, milk, sour cream, salt, black pepper, and garlic powder. Mash the potatoes until smooth and creamy. Taste and adjust seasoning as needed.

Step 5

Fold 1 1/2 cups of the shredded cheddar cheese and half of the chopped bacon into the mashed potatoes, mixing until well combined.

Step 6

Transfer the mashed potato mixture to the prepared casserole dish, spreading it out evenly. Sprinkle the remaining 1/2 cup of cheddar cheese, the remaining bacon, and the Parmesan cheese (if using) evenly over the top.

Step 7

Bake the casserole in the preheated oven for 20 minutes, or until the cheese on top is melted and bubbly. If desired, broil for an additional 2-3 minutes to achieve a golden, crispy topping.

Step 8

Remove the casserole from the oven and sprinkle with the sliced scallions. Let it cool for 5 minutes before serving. Enjoy!
