Creamy Cheesy Mashed Potatoes Recipe — Garlic Parmesan Twist

This cheesy mashed potatoes recipe makes a reliably delicious side dish for weeknight dinners and holiday meals like Thanksgiving, Christmas, or Easter.

You can mash them smooth or leave them a bit chunky—either way the flavor is excellent thanks to plenty of butter, sharp cheddar, sour cream, and a touch of garlic powder. These are the kind of potatoes your family will devour.

These potatoes are perfect with or without gravy and reheat well. Leftovers can easily be transformed into fried mashed potato patties for a tasty second meal.

They pair beautifully with roasted or braised meats such as chicken and stuffing, London broil, meatloaf, Salisbury steak, turkey, ham, or any roast you serve.

Ingredients

What you’ll need:

Notes on ingredients:

• Potatoes: Russets are ideal because they mash into a drier, fluffier texture. Yukon gold or red potatoes work too but may be slightly creamier or denser.
• Butter: Salted butter adds flavor. If you use unsalted, taste and adjust salt as needed.
• Sour cream: Full-fat sour cream gives the best creaminess and flavor; plain yogurt can be a substitute.
• Milk: Whole milk, half-and-half, or cream will yield the creamiest result. Lower-fat milk will make the potatoes less rich.

See the recipe card below for exact quantities and full instructions.

Substitutions & Variations

• Cheese: Sharp cheddar melts well and adds great flavor. Other melty cheeses like Gruyère or Monterey Jack work too, or omit cheese for a simpler version.
• Potatoes: Russets for fluffiness, Yukon gold for creaminess. You can leave thin-skinned potato varieties unpeeled for texture and color.
• Sour cream: Plain yogurt can replace sour cream with similar results.
• Broth: Replace cooking water with chicken, beef, or vegetable broth to boost flavor.

Step-By-Step Instructions

How to make cheesy mashed potatoes from scratch:

Step 1: Peel (or leave skins on if desired), wash, and chop potatoes. Remove any dark spots.

Step 2: Place potatoes in a medium pot and add just enough water to cover. Bring to a boil, reduce heat to low, cover, and simmer about 10 minutes or until tender when pierced with a fork.

Step 3: Drain the potatoes and return them to the pot. Add salt, pepper, garlic powder, parsley, butter, and shredded cheese.

Step 4: Keep the burner on low and mash with a potato masher or fork until the butter and cheese begin to melt into the potatoes.

Step 5: Stir in milk and sour cream and warm gently over low heat until heated through.

Step 6: For extra smooth potatoes, use a hand mixer to blend to your preferred consistency. Taste and adjust salt if needed. Serve hot.

Expert Cooking Tips

• Don’t overcook potatoes: Cook just until tender so they don’t become waterlogged or mealy.
• Keep the sour cream: It adds richness and a pleasant tang—don’t skip it if you can help it.
• Use a mixer for smoothness: A hand mixer, stand mixer, or food processor will give the smoothest results; a masher leaves a more rustic texture.

Russets are my top choice for fluffy, smooth mashed potatoes. Yukon golds create a creamier result. Any variety will work if the potatoes are cooked until very tender.

If cut into similar-sized pieces and simmered covered, potatoes usually take about 10 minutes once the water returns to a simmer. Test with a fork—potatoes should break apart easily when done.

About 2 pounds (roughly 6 small-to-medium potatoes) serves four people. Adjust quantity depending on your serving needs.
