It’s a simple dish, but one that’s packed with memories and flavor – a true testament to the power of comfort food.

Recipe Overview

Prep Time: 25 minutes
Cook Time: 22 minutes
Total Time: 47 minutes
Servings: 4-6
Yield: 1 casserole
Dietary Type: Vegetarian

Ingredients

7 large russet potatoes, peeled and quartered
1/4 cup sour cream (can use more)
5 tablespoons butter
3 ounces cream cheese, softened (low-fat is okay)
1/4 cup 18% table cream
1 1/4 cups old cheddar cheese, shredded
2 teaspoons salt (or to taste, I use seasoned salt)
Black pepper to taste
1/4 cup grated parmesan cheese (or to taste)

Equipment Needed

Large pot
Potato masher or electric mixer
Large bowl
2 or 3-quart casserole dish
Measuring cups and spoons

Instructions

First, prepare the potatoes. Place the peeled and quartered russet potatoes in a large pot and cover them with cold, salted water.
Bring the water to a boil over high heat, then reduce the heat to medium and continue to cook the potatoes until they are tender and easily pierced with a fork, about 20 minutes.
Once the potatoes are cooked, carefully drain them in a colander.
Transfer the drained potatoes to a large bowl.
Add the sour cream, butter, softened cream cheese, and 18% table cream to the bowl with the potatoes.
Using a potato masher or an electric mixer, beat the ingredients together until the potatoes are smooth and creamy. Don’t overmix, as this can make the potatoes gummy.
Add the shredded cheddar cheese to the bowl and mix gently to combine, ensuring the cheese is evenly distributed throughout the mashed potatoes.
Season the mashed potato mixture with salt (or seasoned salt) and black pepper to taste. Adjust the seasoning as needed, adding more salt or pepper until the flavor is to your liking.
Transfer the cheesy mashed potato mixture to a 2 or 3-quart casserole dish, spreading it evenly across the bottom.
Sprinkle the top of the mashed potato bake with the grated parmesan cheese.
At this point, you have two options: you can either cover the casserole dish tightly with plastic wrap and refrigerate it for later, or you can bake it immediately.
If baking immediately, preheat your oven to 350°F (175°C).
Place the casserole dish in the preheated oven and bake for about 20-22 minutes, or until the top is golden brown and the cheese is melted and bubbly. If the casserole was refrigerated, you may need to add an extra 5-10 minutes to the baking time.
Once baked, remove the cheesy mashed potato bake from the oven and let it cool for a few minutes before serving. This will allow the flavors to meld together and prevent any burning.

Expert Tips & Tricks

For the fluffiest mashed potatoes, use a potato ricer instead of a masher. This will prevent overworking the potatoes and keep them light and airy.
If you prefer a tangier flavor, add a tablespoon of Dijon mustard to the mashed potato mixture.
To prevent the cream cheese from clumping, make sure it is fully softened to room temperature before adding it to the potatoes.
If your mashed potatoes seem too thick, add a little more cream or milk until you reach your desired consistency.
For a richer flavor, use brown butter instead of regular butter. Simply melt the butter in a saucepan over medium heat, cooking until it turns a nutty brown color and smells fragrant. Be careful not to burn it!
If you want to prepare this bake a day in advance and it’s not enough cheese on the topping, add a layer of plastic wrap on top to make sure it stays fresh.

Serving & Storage Suggestions

This Cheesy Mashed Potato Bake is a wonderful side dish for any occasion. Serve it alongside roasted meats, poultry, or fish. It’s also delicious with vegetarian mains like lentil loaf or grilled halloumi. For a more casual meal, top it with chili or pulled pork.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350°F (175°C) until warmed through, or microwave in short intervals until heated. You can add a little bit of milk or cream before reheating to retain moisture.

This dish is best enjoyed fresh but can be frozen for up to 2 months. Thaw completely in the refrigerator before reheating. Keep in mind that the texture may change slightly after freezing.
