Description
A creamy mashed potato casserole with a crispy parmesan crust, perfect for holidays and family dinners.
Ingredients
Scale
- 3 lbs russet potatoes, scrubbed, peeled and diced into 1” cubes
- 5 garlic cloves, whole
- 1 teaspoon kosher salt (for water)
- 4 tablespoons unsalted butter
- 1 cup whole milk
- 1 3/4 cups parmesan cheese, shredded and divided
- 1 teaspoon black pepper, freshly ground
- 1.2 teaspoon kosher salt
Instructions
- Chop the scrubbed and peeled potatoes into 1” cubes.
- Fill a large saucepan with water, add potatoes and garlic cloves.
- Season the water with a teaspoon of salt.
- Heat the water and potatoes over high heat and bring to a boil. Cook until potatoes are fork tender, about 20 minutes.
- Drain the potatoes and place back in the saucepan.
- Add butter, milk, and 1 cup of parmesan cheese to the potatoes.
- Use a hand mixer on low speed to blend until smooth and creamy.
- Season with salt and pepper.
- Preheat the oven to 350°F. Spray a 9” x 13” baking dish with nonstick cooking spray.
- Transfer the mashed potatoes into the baking dish. Sprinkle the remaining ¾ cup cheese on top.
- Bake for 25 minutes, then increase heat to 425°F. Bake for an additional 15 minutes, or until cheese has browned.
- Remove from the oven and let cool slightly before serving.
Notes
- Use freshly grated parmesan for the best crust.
- Let the casserole rest for 5 minutes before serving for easier slicing.
