Mashed Potato Casserole Dish

Ingredients:

  • 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 cup breadcrumbs (optional, for topping)

Preparing the Potatoes

  1. Start by washing and peeling the russet potatoes. I like to use large potatoes for this recipe because they yield a creamier texture.
  2. Once peeled, cut the potatoes into even-sized cubes, about 1 to 2 inches. This ensures they cook evenly.
  3. Place the cubed potatoes in a large pot and cover them with cold water. Add a generous pinch of salt to the water to season the potatoes as they cook.
  4. 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 they are fork-tender.
  5. Once cooked, drain the potatoes in a colander and let them sit for a minute to allow excess moisture to evaporate. This step is crucial for achieving a fluffy texture in the final dish.

Making the Mashed Potato Mixture

  1. In a large mixing bowl, add the drained potatoes. Using a potato masher or a hand mixer, begin mashing the potatoes until they reach your desired level of creaminess. I prefer a slightly chunky texture, but you can make them as smooth as you like.
  2. Next, add the softened butter to the mashed potatoes. The warmth of the potatoes will help melt the butter, making it easier to incorporate.
  3. Pour in the sour cream and milk. This combination adds richness and creaminess to the dish. Stir well until everything is combined.
  4. Now, it’s time to season! Add the garlic powder, onion powder, salt, and pepper to taste. I usually start with about a teaspoon of salt and half a teaspoon of pepper, then adjust according to my preference.
  5. Finally, fold in the shredded cheddar cheese and grated Parmesan cheese. The cheese will melt into the warm potatoes, creating a deliciously cheesy flavor throughout.

Assembling the Casserole

  1. Preheat your oven to 350°F (175°C). This will ensure that the casserole bakes evenly and gets that lovely golden top.
  2. Grease a 9×13-inch baking dish with a little butter or cooking spray to prevent sticking.
  3. Transfer the mashed potato mixture into the prepared baking dish. Use a spatula to spread it out evenly, smoothing the top as you go.
  4. If you’re using breadcrumbs for a crunchy topping, sprinkle them evenly over the mashed potatoes. This adds a delightful texture contrast to the creamy potatoes.
  5. For an extra touch, you can sprinkle a little more shredded cheddar cheese on top of the breadcrumbs. Who doesn’t love extra cheese?

Baking the Casserole

  1. Once your casserole is assembled, place it in the preheated oven. Bake for about 25-30 minutes, or until the top is golden brown and the edges are bubbling.
  2. Keep an eye on it during the last few minutes of baking to ensure it doesn’t over-brown. If you notice it getting too dark, you can cover it loosely with aluminum foil.
  3. When the casserole is done, remove it from the oven and let it sit for about 5-10 minutes before serving. This resting time allows the flavors to meld and makes it easier to scoop out portions.

Garnishing and Serving

  1. Before serving, sprinkle the chopped green onions over the top of the casserole for a pop of color and freshness. It adds a nice contrast to the creamy potatoes.
  2. Using
