Ingredients
Scale
Potatoes
- 4 large russet potatoes
Mix-ins
- 1 cup sour cream
- 1 cup shredded cheddar cheese, plus extra for topping
- 1/2 cup milk
- 1/4 cup butter, softened
- 1 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup green onions, chopped
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the potatoes.
- Bake Potatoes: Wash the russet potatoes thoroughly and pierce each several times with a fork to allow steam to escape. Place them directly on the oven rack and bake until tender when pierced with a fork, about 1 hour.
- Prepare Mashed Potato Mixture: Remove the baked potatoes from the oven and let them cool slightly until safe to handle. Cut each potato in half and scoop out the insides into a large bowl. Mash the potato flesh with sour cream, shredded cheddar cheese, milk, softened butter, garlic powder, salt, and black pepper until smooth and creamy.
- Add Green Onions: Stir in the chopped green onions evenly through the mashed potato mixture.
- Assemble Casserole: Transfer the mashed potato mixture into a greased baking dish. Sprinkle additional shredded cheddar cheese evenly over the top for a cheesy crust.
- Bake Casserole: Return the casserole dish to the oven and bake for an additional 25 to 30 minutes, or until the top is golden brown and the casserole is heated through.
Notes
- Russet potatoes are ideal for baking due to their starchy texture, which yields a fluffy mash.
- You can prepare this casserole a day ahead; simply store it in the refrigerator and bake it fresh before serving.
- For an extra crispy top, broil for 2-3 minutes after baking, watching carefully to avoid burning.
- Feel free to add crispy bacon bits or chopped cooked ham for a non-vegetarian variation.
- Substitute cheddar with other melting cheeses like mozzarella or Monterey Jack for different flavors.
