Ingredients
Potatoes and Broth
- 3-4 pounds Yukon Gold or russet potatoes (or a combination)
- 4 cups chicken broth or stock
- Additional water to cover potatoes (about 4 cups)
Cheese Mixture
- 1/2 cup melted butter
- 1/2 cup milk or cream (warmed)
- 1/2 cup sour cream
- 4 ounces softened cream cheese
- 1 cup shredded cheddar cheese (plus extra for topping)
- 1/4 cup grated parmesan cheese (plus extra for topping)
Seasonings and Garnish
- 1 tsp garlic powder
- 3/4 teaspoon salt
- 1/2 teaspoon black pepper
- Chopped chives or parsley for garnish (optional)
Instructions
- Prepare Potatoes: Peel and cut your potatoes into chunks about 2 inches thick and place them in a large empty stock pot.
- Add Broth and Water: Pour chicken broth over the potatoes and add enough water to cover all the potatoes, usually about 4 cups each of water and broth.
- Boil Potatoes: Bring the liquid to a boil and cook the potatoes until they are tender and fall apart easily when poked with a fork.
- Warm Milk and Melt Butter: While the potatoes cook, melt the butter and add it to the milk to warm the milk gently, as cold milk should not be added to the potatoes.
- Prepare Cheese Mixture: Shred cheddar and parmesan cheeses. Soften cream cheese. In a bowl, combine sour cream, cream cheese, shredded cheddar, parmesan, garlic powder, salt, and black pepper; stir until well mixed.
- Mash Potatoes: Drain the cooked potatoes and return them to the pot or place in a large bowl. Pour in the warm milk and melted butter mixture and gently mash until you reach your desired creamy consistency.
- Combine with Cheese: Fold the prepared cheese mixture gently into the mashed potatoes until fully incorporated.
- Assemble in Baking Dish: Spray an 8×10-inch baking dish with non-stick spray and transfer the cheesy mashed potatoes into the dish.
- Broil Cheese Topping: Cover the top of the potatoes with the remaining shredded cheddar cheese and broil for 2-5 minutes until the cheese is melted, bubbly, and slightly golden.
- Make Ahead Instructions: To make ahead, follow all steps through combining the potatoes and cheese mixture but do not broil. Cover the baking dish and refrigerate for up to 3 days. When ready to bake, bring to room temperature for about 2 hours, then bake at 450°F for approximately 15 minutes or until the top is melted and bubbly.
Notes
- Use Yukon Gold potatoes for creamier texture or russet potatoes for fluffier texture.
- Warming the milk before adding prevents cooling the potatoes and helps achieve smooth mashed potatoes.
- Broil carefully to avoid burning the cheese topping; keep a close eye during the last minutes.
- This dish can be made ahead and reheated, making it ideal for holiday meals or meal prep.
- Optional garnish adds a fresh pop of color and flavor – chopped chives or parsley work best.
