Ingredients
Scale
Main Ingredients:
- 4 pounds russet or Yukon gold potatoes
- 2 cups shredded cheddar cheese
- 1 cup milk
- 1 cup sour cream
- 1/2 cup (1 stick) butter
Seasonings and Spices:
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
Optional Toppings:
- 1/4 cup chopped green onions
- 1 cup breadcrumbs
- 1/2 cup grated Parmesan cheese
- 1 cup crispy fried onions
Instructions
- Prepare a buttered 9×13-inch baking dish and heat the oven to 375°F (190°C) for optimal cooking temperature.
- Submerge potato chunks in generously salted water, cooking until fork-tender approximately 20-25 minutes, then thoroughly drain excess liquid.
- Transfer potatoes to a spacious mixing bowl and vigorously mash using a potato masher or electric mixer until achieving a velvety, lump-free consistency.
- Incorporate butter, milk, sour cream, garlic powder, onion powder, salt, and pepper into the mashed potatoes, blending until smooth and creamy.
- Distribute the potato mixture evenly across the prepared baking dish, creating a uniform layer for consistent heating.
- Generously sprinkle shredded cheddar cheese and chopped green onions across the potato surface for enhanced flavor and visual appeal.
- Optional: Enhance the casserole’s texture by scattering breadcrumbs, grated Parmesan cheese, and crispy fried onions over the top.
- Position the casserole in the preheated oven and bake for 25-30 minutes until the surface turns golden brown and the cheese melts completely.
- Remove from oven and let rest for 5 minutes, then garnish with additional green onions before serving hot.
Notes
- Potato Selection Matters: Choose starchy potatoes like Russet or Yukon Gold for the creamiest, most velvety texture in your casserole.
- Creamy Consistency Trick: Warm milk and butter before mixing to prevent cold ingredients from making potatoes gluey and ensure ultra-smooth mashing.
- Flavor Boosting Hack: Roast garlic beforehand or add a splash of sharp white wine to elevate the overall taste profile of the dish.
- Dietary Adaptations: Swap dairy for plant-based alternatives like coconut milk, vegan butter, and nutritional yeast to create a delicious dairy-free version that’s equally indulgent.
