Ingredients
Scale
- 4 large russet potatoes, peeled and cubed
- 1/2 cup unsalted butter, softened
- 1/2 cup sour cream
- 1/2 cup milk
- 1 cup shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
- 1/2 cup green onions, chopped (for garnish)
- 1/2 cup breadcrumbs (optional, for topping)
Instructions
- Start by washing and peeling the russet potatoes. Use a vegetable peeler for quick peeling.
- Cut the potatoes into evenly sized cubes, about 1 to 2 inches.
- Place the cubed potatoes into a large pot and cover them with cold water. Add a generous pinch of salt.
- Bring the pot to a boil over medium-high heat. Once boiling, reduce the heat to medium and let the potatoes simmer for about 15-20 minutes, or until fork-tender.
- Drain the potatoes in a colander and let them sit for a minute to evaporate excess moisture.
- Transfer the drained potatoes back into the pot or a large mixing bowl.
- Add the softened butter to the hot potatoes.
- Add the sour cream and milk. Whole milk is preferred for creaminess.
- Sprinkle in the garlic powder, onion powder, and salt and pepper to taste.
- Mash the potatoes using a potato masher or hand mixer until desired consistency is reached.
- Fold in the shredded cheddar cheese and grated Parmesan cheese until melted and combined.
- Preheat your oven to 350°F (175°C).
- Grease a 9×13-inch baking dish with butter or cooking spray.
- Spoon the mashed potato mixture into the prepared baking dish, smoothing the top.
- If desired, sprinkle breadcrumbs over the top for a crunchy texture.
- Optionally, add more shredded cheddar cheese on top of the breadcrumbs.
- Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and edges are bubbling.
- Monitor during the last few minutes to prevent over-browning; cover loosely with aluminum foil if necessary.
- Remove from the oven and let sit for 5-10 minutes before serving.
- Before serving, sprinkle chopped green onions over the top for added color and freshness.
