Cheesy Mashed Potatoes
This Cheesy Mashed Potatoes casserole is a slightly indulgent recipe that makes a cozy, comforting side dish. Creamy Mashed Potatoes are mixed with shredded cheddar cheese and topped with a cheesy layer that's baked until golden and bubbly.

Ingredients
Instructions
- Step 1
Preheat oven to 375 degrees F. Grease or butter a 2.5-quart casserole dish.
- Step 2
Cut peeled potatoes into large 2-inch chunks. Add them to a large pot, cover with cold water, and season with 1 tablespoon (3 teaspoons) kosher salt. Bring to a boil, then reduce heat and simmer for 12 to 15 minutes, until the potatoes are fork-tender.
- Step 3
Drain potatoes in a colander and let them sit for a few minutes to steam off excess moisture.
- Step 4
Use a potato ricer to rice the potatoes into the pot. You also can use a masher, but avoid overworking the potatoes to keep them fluffy.
- Step 5
Warm the milk and butter in a small saucepan until butter is just melted. Pour the mixture into the potatoes. Add sour cream, remaining 1 teaspoon salt and ½ teaspoon black pepper. Fold gently to combine.
- Step 6
Stir in about ¾ cup of the shredded cheese, until fully incorporated.
- Step 7
Transfer the cheesy mashed potatoes to the prepared baking dish and smooth the top.
- Step 8
Sprinkle the remaining cheese evenly over the potatoes.
- Step 9
Bake for 20 to 25 minutes, until the edges are bubbling and the top is golden. For an extra-crispy finish, broil on high for 2 to 3 minutes, watching closely.
- Step 10
Let the casserole rest for 5 to 10 minutes, and serve warm.
