Ingredients You’ll Need
Gathering these simple but essential ingredients is the first step toward making your Baked Cheesy Mashed Potatoes Recipe shine. Each item plays a crucial role, from creamy butter and sour cream adding richness to the sharp cheddar cheese lending the dish its iconic cheesy crust and flavor.
- 3 lbs russet or Yukon gold potatoes: These varieties provide the perfect fluffy texture once mashed.
- 4 tablespoons unsalted butter: Adds a silky richness and enhances the creamy mouthfeel.
- 3/4 cup whole milk (warmed): Helps make the potatoes smooth and creamy without cooling them down.
- 1/2 cup sour cream: Brings tangy depth and extra creaminess to the mash.
- 1 teaspoon salt: Essential for seasoning and amplifying all the flavors.
- 1/2 teaspoon black pepper: Adds a subtle warmth and balances the richness.
- 1/2 teaspoon garlic powder: Infuses a gentle garlic aroma without overpowering the dish.
- 1 1/2 cups shredded cheddar cheese (divided): The star cheese that melts beautifully for that bubbly, golden topping.

- Chopped chives or green onions (optional): For a fresh, mild oniony garnish to brighten each bite.
How to Make Baked Cheesy Mashed Potatoes Recipe
Step 1: Prep and Cook the Potatoes
Start by peeling and chunking your potatoes into evenly sized pieces so they cook uniformly. Placing them in cold water before heating prevents premature cooking and helps achieve the perfect fluffy texture. Boil and then simmer these chunks until they’re fork-tender, which usually takes about 15 to 20 minutes — this is the foundation for that luscious mash.
Step 2: Mash and Mix in Creamy Ingredients
Drain the potatoes well, then return them to the pot. Add softened butter, warmed milk, and tangy sour cream. Season with salt, black pepper, and garlic powder. Mash everything together until the potatoes are silky and smooth, creating an irresistible creamy base. Then fold in a whole cup of shredded cheddar cheese to boost that cheesy flavor inside the mixture.
Step 3: Assemble and Bake
Transfer your cheesy mashed potatoes into a greased 9×13-inch baking dish, smoothing the surface with a spatula. Sprinkle the remaining cheddar cheese and Parmesan cheese evenly over the top to build that glorious crust. Pop this into a 375°F oven uncovered for about 20 to 25 minutes, until the cheese is melted, bubbly, and lightly golden. This step transforms simple mashed potatoes into a tantalizing baked delight.
How to Serve Baked Cheesy Mashed Potatoes Recipe
Garnishes
A sprinkle of freshly chopped chives or green onions isn’t just for looks — it adds a fresh, slightly sharp contrast to the rich, cheesy potatoes, brightening each bite and adding a lovely color pop. A little garnish makes your dish feel even more inviting and thoughtfully prepared.
Side Dishes
This Baked Cheesy Mashed Potatoes Recipe pairs beautifully with roasted meats like turkey, chicken, or beef, especially during festive meals. Add a crisp green salad or some sautéed vegetables on the side to balance the rich potatoes with refreshing textures and flavors.
Creative Ways to Present
Feeling fancy? Serve the baked cheesy mashed potatoes in individual ramekins or small cast iron skillets for personal portions that are picture-perfect. For a fun twist, swirl the top with a fork pattern before baking to give a beautiful textured crust that crisps up gorgeously.
Make Ahead and Storage
Storing Leftovers
Leftover baked cheesy mashed potatoes can be stored in an airtight container in the refrigerator for up to three days. Make sure to cool them fully before sealing to maintain freshness and avoid sogginess.
Freezing
If you want to prepare this Baked Cheesy Mashed Potatoes Recipe ahead of time, freeze the unbaked mashed potato mixture after mashing for up to two months. Thaw overnight in the fridge before baking as directed for a convenient yet tasty meal addition any day.
Reheating
To reheat leftovers, place them back in the oven at 350°F, covered with foil to avoid drying out, for about 20 minutes or until heated through. If frozen, give extra thaw time. You can also microwave smaller portions on medium power, stirring midway to ensure even warming.
FAQs
Can I use other types of potatoes?
Definitely! Russet or Yukon gold are preferred because they’re fluffy and mash easily, but you can experiment with red potatoes or fingerlings for different textures—just keep in mind the mash might be less creamy.
Is there a way to make this recipe dairy-free?
Yes! Substitute the butter with a plant-based spread, use dairy-free milk alternatives warmed before mixing, and choose vegan sour cream and cheese options. It won’t be exactly the same, but still delicious.
Can I add herbs or spices to customize the flavor?
Absolutely. Fresh rosemary, thyme, or smoked paprika can add exciting layers of flavor. Just add herbs during the mashing stage to infuse their aromas throughout the dish.
How do I avoid soggy mashed potatoes before baking?
Be sure to drain the potatoes thoroughly after boiling and dry them slightly by returning to the warm pot off the heat for a minute. This helps evaporate excess moisture for creamier, less watery results.
Can this recipe be doubled or halved?
Yes! It scales well in either direction, just adjust your baking dish size accordingly and keep an eye on the baking time—it might need a few extra minutes or less depending on thickness.
