Cheesy mashed potatoes with sour cream are rich, creamy, and simple to make. This easy side dish turns classic mashed potatoes into a comforting recipe that is hearty enough for holidays, family dinners, and cozy weeknight meals.
This cheesy mashed potatoes recipe is a creamy, crowd-pleasing side dish made with tender potatoes, sour cream, butter, half and half, and shredded cheese. It has all the comfort of traditional mashed potatoes, but the melted cheese and tangy sour cream make it feel extra special without requiring complicated steps or unusual ingredients.
These potatoes are perfect for a holiday table, Sunday dinner, potluck, or simple family meal. They pair well with roasted meats, ham, pork chops, green beans, asparagus, and many other classic dinner favorites. Because the recipe uses basic pantry and refrigerator staples, it is also easy to prepare when you need a filling side dish that tastes homemade and satisfying.
One of the best things about cheesy mashed potatoes is how flexible the recipe can be. Yukon Gold potatoes are naturally creamy and make a smooth mash, but russet potatoes or red potatoes can also be used. Colby Jack and cheddar cheese both melt well and add a familiar flavor, while Parmesan, mozzarella, goat cheese, or sharp cheddar can create a slightly different taste. You can also adjust the seasoning to suit your meal by adding extra garlic powder, fresh garlic, onion powder, chives, green onions, or fresh herbs.
If you are looking for a comforting side dish that feels a little more indulgent than plain mashed potatoes, this recipe is a great choice. The sour cream keeps the texture light and fluffy, while the butter and cheese add richness. Serve these cheesy mashed potatoes hot for the best flavor and texture.
Cheesy Mashed Potatoes Ingredients
- Potatoes – Yukon Gold potatoes are preferred because they mash smoothly and have a naturally buttery texture. Russet potatoes or red potatoes may also be used.
- Sour cream – Sour cream gives the mashed potatoes a light, creamy texture and a gentle tang. Cream cheese can be used instead, but it will make the potatoes thicker and denser.
- Half and half – Half and half helps create a smooth, creamy consistency. Whole milk or heavy cream can be substituted if needed.
- Butter – Butter adds classic mashed potato flavor and richness.
- Shredded cheese – Colby Jack or cheddar cheese works especially well, but you can use your favorite shredded cheese.
- Seasonings – Salt, black pepper, and garlic powder keep the flavor simple, savory, and balanced. Adjust the amounts to taste.
How to Make Cheesy Mashed Potatoes
Start by peeling and cubing the potatoes so they cook evenly. Place the potatoes in a large pot, cover them with water, and add a generous pinch of salt. Bring the water to a boil and cook the potatoes until they are fork tender, about 15 to 20 minutes. The potatoes should be soft enough to mash easily without resistance.
Drain the cooked potatoes well, then return them to the warm pot. Add the butter first and begin mashing so it melts into the potatoes. Gradually add the sour cream, half and half, shredded cheese, garlic powder, salt, and pepper. Continue mashing until the potatoes are smooth and creamy. Taste and adjust the seasoning if needed before serving.
For the best texture, add the liquid ingredients slowly. This makes it easier to control how creamy the potatoes become. If you like a thicker mash, use a little less half and half. If you prefer softer, creamier potatoes, add a small amount more until the texture is just right. Serve immediately while the cheese is melted and the potatoes are warm.
