Ingredients
For the Mashed Potatoes:
- 2.5 pounds Russet potatoes, peeled and quartered
- 1 cup heavy cream, warmed
- 8 tablespoons (1 stick) unsalted butter, softened
- 4 ounces cream cheese, softened
- 1/2 cup sour cream
- 2 teaspoons salt, or to taste
- 1/2 teaspoon black pepper, or to taste
- 1/4 teaspoon garlic powder
For the Topping:
- 1/2 cup shredded cheddar cheese
- 1/4 cup grated Parmesan cheese
- 2 tablespoons butter, melted
- 1/4 cup chopped fresh chives or green onions (optional)
Step-by-Step Instructions

Get Started: Preheat and Prep
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This step ensures your Baked Mashed Potatoes bake evenly and don’t stick.
Boil the Potatoes:
- Place the quartered potatoes in a large pot and cover with cold water. Add a generous pinch of salt to the water.
- Bring the water to a boil over high heat, then reduce the heat to medium and simmer for 15-20 minutes, or until the potatoes are fork-tender. They should easily break apart when pierced with a fork.
- Drain the potatoes thoroughly in a colander.
Mash the Potatoes:
- Return the drained potatoes to the pot. Place the pot back on the burner over low heat for about a minute to evaporate any excess moisture. This is a crucial step for preventing watery mashed potatoes!
- Remove the pot from the heat. Add the warm heavy cream, softened butter, softened cream cheese, and sour cream to the potatoes.
- Using a potato masher or an electric mixer (be careful not to overmix!), mash the potatoes until smooth and creamy. Don’t be afraid to use a ricer for extra smooth results!
- Stir in the salt, pepper, and garlic powder. Taste and adjust seasonings as needed. I sometimes add a pinch of nutmeg for a little extra warmth, especially when serving these as Holiday sides.
Assemble and Bake:
- Transfer the mashed potatoes to the prepared baking dish, spreading them evenly.
- In a small bowl, combine the shredded cheddar cheese, grated Parmesan cheese, and melted butter. Sprinkle the cheese mixture evenly over the top of the mashed potatoes.
- Bake in the preheated oven for 20-25 minutes, or until the topping is golden brown and bubbly.
- Remove from the oven and let cool for a few minutes before garnishing with chopped chives or green onions, if desired.
Tips and Tricks for Potato Perfection
Choosing the Right Potatoes:
Russet potatoes are my go-to for classic mashed potatoes because of their high starch content, which results in a light and fluffy texture. However, Yukon Gold potatoes are another excellent choice – they have a naturally buttery flavor and a slightly denser texture. Feel free to experiment and see which you prefer! And, if you’re in the mood for something different, you could even try using a combination of both.
Warming the Cream:
Warming the heavy cream is an important step because it helps the butter and cream cheese melt evenly into the potatoes, preventing lumps and creating a smoother consistency. You can warm the cream in a saucepan over low heat or in the microwave in 30-second intervals, stirring in between, until it’s warm but not boiling.
Preventing Gummy Potatoes:
The key to avoiding gummy mashed potatoes is to avoid overmixing them. Overmixing releases too much starch, resulting in a gluey texture. If using an electric mixer, mix on low speed just until the potatoes are smooth. A potato masher or ricer is a great alternative for achieving a smooth texture without overmixing.
Customizing Your Baked Mashed Potatoes:
The beauty of this recipe is that it’s easily customizable to your liking! Feel free to add different cheeses, such as Gruyere or Monterey Jack, to the topping. You can also mix in cooked bacon, ham, or vegetables like roasted garlic or caramelized onions for added flavor. Get creative and make it your own!
