Garlic Mashed Potatoes
These creamy, buttery garlic mashed potatoes transform any meal into something special. Fresh garlic cloves simmer right alongside the russet potatoes, then get mashed together with butter, milk, and sour cream for incredible depth of flavor. The garlic mellows during cooking, becoming sweet and fragrant without any harsh bite. Ready in about 30 minutes using simple pantry staples, this foolproof side dish is fluffy yet rich, make-ahead friendly, and a universal crowd pleaser that pairs beautifully with roasted meats, holiday feasts, or weeknight dinners.
Equipment
- Large pot (at least 6-quart capacity) - For boiling potatoes and garlic
- Potato masher or electric hand mixer - For mashing; use lowest speed on mixer to avoid gummy texture
- Colander - For draining potatoes
- Small saucepan - For heating milk and butter
- Cutting board
- Sharp knife
- Measuring cups and spoons
- Wooden spoon or spatula - For stirring
Ingredients
- 3 pounds russet potatoes - 1.36 kg, peeled and cut into 2-inch chunks
- 6 garlic cloves - peeled and smashed
- 1 tablespoon kosher salt - 15 g, plus more to taste; for cooking water
- 1/2 cup whole milk - 120 ml
- 6 tablespoons unsalted butter - 85 g
- 1/2 cup sour cream - 120 g
- 1/2 teaspoon black pepper - 2.5 g
- fresh chives - chopped, for garnish (optional)
Instructions
- Peel the russet potatoes and cut into roughly 2-inch chunks for even cooking. Keep pieces uniform and place in a bowl of cold water to prevent browning.
- Drain the potatoes and place in a large pot with the smashed garlic cloves. Cover with cold water by 1 inch and add 1 tablespoon kosher salt. Bring to a rolling boil over high heat (8-10 minutes).
- Reduce heat to medium-low and simmer uncovered for 15-20 minutes until potatoes are fork-tender and garlic has mellowed. Drain thoroughly in a colander, shaking off excess water, then return immediately to the hot pot.
- While potatoes cook, combine milk and butter in a small saucepan. Heat over medium-low until butter melts and mixture is steaming hot (do not boil). Keep warm.
- Mash the hot potatoes and garlic with a potato masher until most lumps are broken down but some texture remains. Avoid over-mashing to prevent gummy potatoes. If using a hand mixer, use lowest speed in short bursts.
- Pour the warm milk-butter mixture over the mashed potatoes. Add sour cream and black pepper. Stir gently until creamy and combined. Taste and adjust salt as needed for fluffy, well-seasoned consistency.
- Transfer to a serving bowl. Optionally add a pat of butter in the center to melt and garnish with chopped fresh chives. Serve immediately while hot.
Notes
- Start potatoes in cold water and bring to a boil together for even cooking.
- Season the cooking water generously with salt so potatoes absorb flavor from the inside.
- Always warm the milk and butter before adding to hot potatoes for the smoothest texture.
- Work quickly while potatoes are hot; do not overmix or they will become gummy.
- For make-ahead: Prepare up to 2 days in advance, refrigerate in an airtight container, and reheat gently with extra milk or cream to restore creaminess.
- Variations: Use roasted garlic for sweeter flavor, add cream cheese for extra richness, or stir in herbs like rosemary or thyme.
- Storage: Refrigerate leftovers up to 4 days or freeze up to 2 months (texture may change slightly). Reheat on stovetop or in oven with added dairy.
- Russet potatoes give fluffy texture; Yukon Gold can be substituted or combined for buttery flavor.
- Adjust consistency by adding warm milk 1 tablespoon at a time if too thick.
- Perfect pairing: Serve with roasted turkey, pot roast, gravy, or as a base for shepherd's pie.
