Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x9-inch (or similar-sized) casserole dish.

In a medium saucepan, bring 2 cups of water to a boil. Remove the saucepan from heat and stir in the milk and butter until the butter is melted.

Spoon the potato mixture into the prepared casserole dish, spreading it out evenly.

Step 7

Sprinkle the remaining 0.5 cup of shredded cheddar cheese over the top of the mashed potatoes.

Step 8

Bake the casserole in the preheated oven for 20 minutes, or until the cheese on top is melted and bubbly.

Step 9

Remove the casserole from the oven and sprinkle the crispy fried onions evenly over the top.

Step 10

Return the casserole to the oven and bake for an additional 5 minutes, or until the fried onions are golden brown and crispy.

Step 11

Garnish the casserole with chopped fresh parsley before serving. Serve warm and enjoy!
