Recipe Information
Ingredients
- 2 cups instant mashed potato flakes
- 2 cups water
- 1 cup milk
- 4 tablespoons unsalted butter
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 cup sour cream
- 1.5 cups shredded cheddar cheese
- 0.75 cup crispy fried onions
- 2 tablespoons chopped fresh parsley
Instructions
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.
Stir the instant mashed potato flakes into the saucepan until smooth and creamy. Let the mixture sit for 1 minute to thicken.
Mix in the garlic powder, onion powder, salt, black pepper, and sour cream to the mashed potatoes until well incorporated.
Fold 1 cup of the shredded cheddar cheese into the potato mixture until evenly distributed.
Spoon the potato mixture into the prepared casserole dish, spreading it out evenly.
Sprinkle the remaining 0.5 cup of shredded cheddar cheese over the top of the mashed potatoes.
Bake the casserole in the preheated oven for 20 minutes, or until the cheese on top is melted and bubbly.
Remove the casserole from the oven and sprinkle the crispy fried onions evenly over the top.
Return the casserole to the oven and bake for an additional 5 minutes, or until the fried onions are golden brown and crispy.
Garnish the casserole with chopped fresh parsley before serving. Serve warm and enjoy!
