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)
- 1/2 cup breadcrumbs (optional, for topping)
Preparing the Potatoes
- Start by washing and peeling the russet potatoes. I like to use a vegetable peeler for this task, as it makes the process quick and easy.
- Once peeled, cut the potatoes into even-sized cubes, about 1 to 2 inches. This ensures they cook evenly.
- Place the cubed potatoes into 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.
- 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. You can test this by poking a potato cube with a fork; it should slide in easily.
- Once cooked, drain the potatoes in a colander and let them sit for a minute to allow excess moisture to evaporate.
Making the Mashed Potato Mixture
- Transfer the drained potatoes back into the pot or a large mixing bowl. This is where the magic happens!
- Add the softened butter to the hot potatoes. The heat from the potatoes will help melt the butter, making it easier to mix in.
- Next, add the sour cream and milk. I prefer using whole milk for a creamier texture, but you can use any milk you have on hand.
- Sprinkle in the garlic powder, onion powder, and a good amount of salt and pepper. Adjust the seasoning to your taste; I usually start with about 1 teaspoon of salt and 1/2 teaspoon of pepper.
- Using a potato masher or a hand mixer, mash the potatoes until they reach your desired consistency. I like mine creamy but still with a few lumps for texture.
- Once mashed, fold in the shredded cheddar cheese and grated Parmesan cheese. The cheese will melt into the warm potatoes, creating a deliciously cheesy flavor.
Assembling the Casserole
- Preheat your oven to 350°F (175°C). This will ensure that the casserole is hot and bubbly when its done baking.
- Grease a 9×13-inch baking dish with a little butter or cooking spray to prevent sticking.
- Transfer the mashed potato mixture into the prepared baking dish, spreading it out evenly with a spatula. Make sure to smooth the top for an even bake.
- If you like a crunchy topping, sprinkle the breadcrumbs evenly over the top of the mashed potatoes. This step is optional, but it adds a nice texture contrast.
- For an extra touch, you can sprinkle a little more shredded cheddar cheese on top of the breadcrumbs. Who doesnt love more cheese?
Baking the Casserole
- 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.
- Keep an eye on it during the last few minutes of baking to ensure it doesnt over-brown. If you notice it getting too dark, you can cover it loosely with aluminum foil.
- Once done, remove the casserole from the oven and let it sit for about 5-10 minutes before serving. This resting time allows the flavors to meld together and makes it easier to scoop out portions.
Garnishing and Serving
- Before serving, sprinkle the chopped green onions over the top for a fresh
