Ingredients Quantity
Preparation time: 20 minutes
Cooking time: 25–30 minutes
Total time: Approximately 50 minutes
Servings: 6–8
- 3 pounds (1.4 kg) russet or Yukon Gold potatoes, peeled and cubed
- 1 cup (240 ml) sour cream
- 1/2 cup (115 g) unsalted butter, melted
- 1/2 cup (120 ml) whole milk, warmed
- 2 cups (200 g) shredded cheddar cheese, divided
- 1/2 teaspoon garlic powder
- 1 teaspoon salt, or to taste
- 1/2 teaspoon black pepper
- 2 tablespoons chopped fresh chives or green onions, optional
Optional Additions
You can customize this casserole with different ingredients to suit your taste.
- Crispy bacon: Add 1/2 cup of cooked, crumbled bacon for a smoky flavor.
- Mozzarella cheese: Replace some of the cheddar with mozzarella for extra stretchiness.
- Cream cheese: Add 4 ounces (115 g) softened cream cheese for a richer, silkier texture.
- Parmesan cheese: Sprinkle 1/4 cup of grated Parmesan over the top for a savory crust.
- Caramelized onions: Mix in 1/2 cup of caramelized onions for sweetness and depth.
- Fresh herbs: Add parsley, thyme, or rosemary for extra aroma.
- Paprika: Sprinkle a little paprika on top for color and mild smoky flavor.
Tips for Success
- Choose the right potatoes: Russet potatoes create a fluffy texture, while Yukon Gold potatoes produce naturally creamy mashed potatoes.
- Cook until tender: The potatoes should be easily pierced with a fork before draining.
- Drain thoroughly: Excess water can make the casserole soggy.
- Warm the milk: Warm milk blends more easily into the potatoes and helps maintain a smooth texture.
- Avoid overmixing: Mash until smooth, but avoid excessive beating, which can make potatoes gluey.
- Reserve some cheese: Sprinkle the remaining cheese over the casserole before baking for a delicious melted topping.
- Watch the baking time: Bake until the cheese is melted and the edges are lightly golden. Avoid overbaking, which can dry out the potatoes.
Instructions
Step 1: Prepare the oven
Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish with butter or cooking spray.
Step 2: Cook the potatoes
Place the peeled, cubed potatoes in a large pot and cover them with cold water. Add a pinch of salt and bring to a boil. Reduce the heat and simmer for 15–20 minutes, or until the potatoes are fork-tender.
Step 3: Drain and mash
Drain the potatoes thoroughly and return them to the pot. Mash until mostly smooth.
Step 4: Add the creamy ingredients
Stir in the melted butter, sour cream, warm milk, garlic powder, salt, and black pepper. Mix gently until creamy and well combined.
Step 5: Add the cheese
Fold in 1 1/2 cups of shredded cheddar cheese. Stir until the cheese is evenly distributed throughout the mashed potatoes.
Step 6: Assemble the casserole
Transfer the potato mixture to the prepared baking dish and spread it evenly. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
Step 7: Bake
Bake uncovered for 25–30 minutes, or until the casserole is heated through and the cheese is melted and lightly golden.
Step 8: Garnish and serve
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with chopped chives or green onions, if desired, and serve warm.
