Ingredients You’ll Need

* **Milk or Cream:** Helps create a smooth and creamy texture. Whole milk or heavy cream will both work well; heavy cream will yield a richer result.
* **Sour Cream:** Adds tanginess and moisture to the casserole, balancing the richness of the other ingredients.
* **Cheese:** Cheddar cheese is a classic choice, but you can use your favorite cheese or a combination of cheeses. Monterey Jack, Gruyere, or even a sprinkle of Parmesan would be delicious.
* **Garlic Powder:** Adds a subtle savory flavor.
* **Onion Powder:** Enhances the overall flavor profile.
* **Salt and Pepper:** To taste. Season generously to bring out the flavors of the other ingredients.

Equipment You’ll Need

* **Large Pot:** For boiling the potatoes.
* **Potato Masher or Electric Mixer:** For mashing the potatoes. An electric mixer will create a smoother, creamier result.
* **9×13 Inch Baking Dish:** For baking the casserole.
* **Measuring Cups and Spoons**
* **Mixing Bowls**

Step-by-Step Instructions

Here’s a detailed guide to making the best mashed potato casserole:

**1. Prepare the Potatoes:**

* **Wash and Peel:** Thoroughly wash the potatoes. Peel them and cut them into roughly 1-inch cubes. Cutting the potatoes into smaller pieces ensures they cook evenly and quickly.
* **Boil the Potatoes:** Place the cubed potatoes in a large pot and cover them with cold water. Add about a teaspoon of salt to the water. Bring the water to a boil over high heat. Once boiling, reduce the heat to medium and cook for about 15-20 minutes, or until the potatoes are fork-tender. A fork should easily pierce through the potato cubes.
* **Drain the Potatoes:** Carefully drain the cooked potatoes in a colander. Make sure to remove all the water.

**2. Mash the Potatoes:**

* **Return to Pot:** Return the drained potatoes to the pot.
* **Add Butter:** Add the butter to the hot potatoes. The heat from the potatoes will melt the butter quickly.
* **Mash:** Using a potato masher or an electric mixer, begin mashing the potatoes. If using an electric mixer, start on low speed to avoid splattering.
* **Add Milk/Cream and Sour Cream:** Gradually add the milk or cream and sour cream to the potatoes while continuing to mash or mix. Add enough liquid to achieve your desired consistency. The potatoes should be smooth and creamy but not watery.
* **Season:** Add the garlic powder, onion powder, salt, and pepper to taste. Mix well to combine. Taste and adjust seasonings as needed. Don’t be afraid to be generous with the seasonings – they make a big difference in the overall flavor.

**3. Assemble the Casserole:**

* **Preheat Oven:** Preheat your oven to 350°F (175°C).
* **Grease Baking Dish:** Lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking to the dish.
* **Spread Potatoes:** Spread the mashed potatoes evenly into the prepared baking dish.
* **Top with Cheese:** Sprinkle the shredded cheddar cheese (or your cheese of choice) evenly over the mashed potatoes.

**4. Bake the Casserole:**

* **Bake:** Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the top is lightly golden brown. Keep a close eye on it to prevent the cheese from burning.

**5. Add Optional Toppings (Optional):**

* **Toppings:** If desired, sprinkle crispy fried onions, bacon bits, chopped chives, or paprika over the top of the casserole during the last few minutes of baking or after it comes out of the oven. These additions add extra flavor and texture.

**6. Serve and Enjoy:**

* **Cool Slightly:** Let the casserole cool for a few minutes before serving.
* **Serve:** Serve warm and enjoy! This mashed potato casserole is a delicious side dish for roast chicken, steak, pork, ham, or any other main course.

Tips for the Best Mashed Potato Casserole

* **Use High-Quality Potatoes:** The type of potatoes you use makes a big difference in the final result. Russet potatoes are generally considered the best for mashed potatoes because they are starchy and fluffy. Yukon Gold potatoes are a good alternative for a creamier texture.
* **Don’t Overcook the Potatoes:** Overcooked potatoes can become waterlogged and gummy. Cook them until they are fork-tender but not mushy.
* **Warm the Milk/Cream:** Warming the milk or cream before adding it to the potatoes helps to prevent them from becoming cold and gluey.
* **Don’t Overmix:** Overmixing the potatoes can result in a gummy texture. Mix them just until they are smooth and creamy.
* **Season Generously:** Salt and pepper are essential for bringing out the flavors of the potatoes and other ingredients. Don’t be afraid to season generously.
* **Customize with Your Favorite Flavors:** Feel free to add your favorite herbs, spices, or vegetables to the mashed potatoes. Roasted garlic, caramelized onions, or chopped rosemary would all be delicious additions.
* **Make it Ahead:** This casserole can be made ahead of time and baked later. Prepare the casserole up to the point of baking, cover it tightly with plastic wrap, and store it in the refrigerator for up to 24 hours. When you’re ready to bake it, remove it from the refrigerator about 30 minutes before baking to allow it to come to room temperature slightly. You may need to add a few extra minutes to the baking time.
* **Prevent discoloration:** To prevent the mashed potatoes from discoloring if making ahead, press a piece of plastic wrap directly onto the surface of the potatoes before covering the dish. This will prevent oxidation.
* **Cheese Selection:** Sharp cheddar offers a robust flavor, while mild cheddar is more subtle. Experiment with different cheeses like Gruyere, Monterey Jack, or a blend for a unique taste.
* **Bacon Bliss:** Crispy bacon bits are a fantastic addition! Cook and crumble bacon, adding some to the mashed potato mixture and sprinkling the rest on top before baking.

Variations and Add-Ins

This mashed potato casserole is a blank canvas for your culinary creativity. Here are some ideas for variations and add-ins:

* **Broccoli Cheddar Mashed Potato Casserole:** Add steamed or roasted broccoli florets and cheddar cheese for a vegetable-packed casserole.
* **Mushroom Mashed Potato Casserole:** Sauté sliced mushrooms and add them to the mashed potatoes for an earthy flavor.
* **Sweet Potato Mashed Potato Casserole:** Use half sweet potatoes and half russet potatoes for a slightly sweeter and more colorful casserole.
* **French Onion Mashed Potato Casserole:** Caramelize onions slowly until golden brown and sweet, then mix into the mashed potatoes and top with Gruyere cheese before baking.
* **Spinach and Artichoke Mashed Potato Casserole:** Mix in chopped spinach and artichoke hearts for a sophisticated and flavorful twist.

Storage and Reheating Instructions

* **Storage:** Store leftover mashed potato casserole in an airtight container in the refrigerator for up to 3-4 days.
* **Reheating:** Reheat the casserole in the oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also reheat it in the microwave, but it may not be as evenly heated. Add a splash of milk or cream before reheating to restore moisture if needed.
* **Freezing:** While mashed potatoes can be frozen, the texture may change slightly upon thawing. The casserole may become a little grainy. To freeze, let the casserole cool completely, then wrap it tightly in plastic wrap and aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
