- ½ cup butter – For that essential richness and smooth texture.
- 1 cup sour cream – Adds a lovely tang and extra creaminess that makes these potatoes so decadent.
- ½ cup milk – Helps achieve the perfect consistency; warm it slightly for best results.
- 3 cups shredded white cheddar, plus 1 cup for topping – The star of the show, providing that irresistible cheesy flavor.

- ½ teaspoon cracked black pepper – Adds a subtle bite.

How to Make Baked Mashed Potatoes Cheddar
- Step 1: To get started on these delicious baked mashed potatoes cheddar, preheat your oven to 375°F (190°C). Peel your russet potatoes and halve them. Place them in a large pot, cover with cold water, and bring to a boil. Let them simmer for about 30 minutes, or until they’re fork-tender.
- Step 2: Once the potatoes are tender, drain them really well. Pop them back into the empty pot and let them sit for a minute or two over low heat to let any extra moisture evaporate. This is key for avoiding watery mashed potatoes.
- Step 3: Now for the magic! Add the ½ cup butter, 1 cup sour cream, and ½ cup milk to the pot with the potatoes. Toss in 3 cups of the shredded white cheddar. Mash everything together over low heat until it’s wonderfully smooth and fluffy, creating those signature creamy mashed potatoes.
- Step 4: Stir in the seasonings: 1 teaspoon salt, ½ teaspoon cracked black pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, and 2 teaspoons dried thyme. Give it a good taste and adjust anything you think it needs.
- Step 5: Spoon your glorious mashed potato mixture into a greased 9×13-inch ovenproof dish. Smooth the top so it’s nice and even. Sprinkle the remaining 1 cup of cheddar cheese evenly all over the surface, ensuring maximum cheesy goodness.
- Step 6: Cover the dish tightly with foil. Bake in your preheated oven for 30 minutes. Then, carefully remove the foil and bake for another 15 minutes, or until the cheese on top is beautifully golden brown and bubbling. The aroma will be incredible!
- Step 7: Once they’re perfectly baked, take the dish out of the oven and let them rest for a few minutes. This allows the cheese to set slightly. Sprinkle with fresh chopped chives for a pop of color and freshness before serving your amazing creamy mashed potatoes.

Pro Tips for the Best Baked Mashed Potatoes Cheddar
Elevating your mashed potatoes is easy with these insider tips. They ensure your dish is always a showstopper:
- Always start with starchy russet potatoes; they absorb butter and cheese beautifully.
- Warm your milk and butter gently before adding them to the potatoes. This helps create a smoother, more integrated mash.
- Don’t overmix the potatoes once you add the liquids and cheese. Gentle mashing prevents them from becoming gummy.
- For an extra layer of flavor, consider adding a pinch of nutmeg or a dash of hot sauce to the potato mixture.

How do I avoid common mistakes with Baked Mashed Potatoes Cheddar?

How to Store and Reheat Baked Mashed Potatoes Cheddar
Even though this easy potato recipe is best served fresh, you can absolutely store and reheat leftovers. Make sure to let the baked mashed potatoes cool down completely before storing. Transfer them to an airtight container. Properly stored, they’ll last in the refrigerator for about 3 to 4 days. For longer storage, these cheesy baked potatoes freeze beautifully for up to 3 months. Just be sure to use a freezer-safe container to prevent freezer burn.
When you’re ready to reheat, the method depends on how you stored them. For refrigerated portions, gently warm them in the oven at around 300°F (150°C) until heated through, or microwave them in short bursts, stirring halfway.

Frequently Asked Questions About Baked Mashed Potatoes Cheddar
Can I freeze baked mashed potatoes cheddar?
Yes, you can freeze these delicious cheesy baked potatoes! After baking, let them cool completely. Transfer to an airtight, freezer-safe container. They should keep well for up to 3 months. Thaw them overnight in the refrigerator before reheating to maintain their creamy texture.
What kind of potatoes are best for baked mashed potatoes cheddar?
For the fluffiest and creamiest results, russet potatoes are your best bet. Their high starch content makes them ideal for mashing and absorbing all those rich, cheesy flavors. Avoid waxy potatoes like red or Yukon Gold, as they can result in a denser, gummier texture.
How do I make the cheese topping extra crispy?
To get a really crispy, golden cheese topping on your cheesy baked potatoes, make sure your oven is fully preheated. After the initial 30 minutes of covered baking, remove the foil and increase the oven temperature slightly to 400°F (200°C) for the last 10-15 minutes. Keep an eye on them to prevent burning.
Can I use different types of cheese for baked mashed potatoes cheddar?
Absolutely! While white cheddar is fantastic, feel free to experiment. A sharp cheddar, Gruyere, Monterey Jack, or even a blend of your favorites will work wonderfully. Just ensure you have about 4 cups of shredded cheese in total for that perfect cheesy goodness in your baked mashed potatoes cheddar.
Variations of Baked Mashed Potatoes Cheddar You Can Try
While this classic recipe for baked mashed potatoes cheddar is amazing as-is, there’s always room for a little creativity! Here are a few ideas to switch things up:
- Smoked Gouda & Bacon: Swap half the white cheddar for smoked Gouda and mix in some crispy, crumbled bacon before baking for a smoky, savory twist.
- Garlic Herb Roasted Potatoes: Instead of boiling, roast the potatoes with garlic and herbs before mashing. This deepens the flavor and creates incredible cheddar mashed potatoes with a more complex taste.
- Sweet Potato Mash: Try using a mix of sweet potatoes and russets for a subtly sweet and vibrant dish. The sweetness pairs wonderfully with the sharp cheddar.
- Vegan Version: Use plant-based butter, unsweetened almond milk, vegan sour cream, and your favorite dairy-free cheddar shreds for a delicious vegan take on this comfort food favorite.
