Mashed potatoes are a timeless comfort food, beloved for their creamy texture and mild, buttery flavor. When preparing for a large crowd, this recipe scales up efficiently without compromising quality, ensuring every guest enjoys smooth, fluffy mashed potatoes that complement any meal.
Ingredients
- 10 pounds Yukon Gold or Russet potatoes (about 20 medium potatoes)
- 1 1/4 cups unsalted butter (2 1/2 sticks), cut into pieces
- 3 to 4 cups whole milk, warmed
- 2 teaspoons salt, plus more to taste
- 1 teaspoon freshly ground black pepper
- Optional: 1 cup sour cream or cream cheese for extra creaminess
- Optional: 2 cloves garlic, peeled (for garlic mashed potatoes)
Instructions
- Prep the potatoes: Peel the potatoes (if desired; Yukon Gold skins can be left on for texture) and cut them into roughly 2-inch chunks. This ensures even cooking.
- Boil the potatoes: Place the potatoes in a large stockpot and cover with cold water by about 2 inches. Add 2 teaspoons of salt to the water. Optionally, add garlic cloves to infuse subtle flavor. Bring to a boil over high heat, then reduce to a simmer. Cook until potatoes are fork-tender, about 20-25 minutes.
- Drain and dry: Drain the potatoes thoroughly in a colander. Return them to the hot pot and place over low heat for 1-2 minutes, stirring gently, to evaporate excess moisture. This step prevents watery mashed potatoes.
- Warm the dairy: In a small saucepan or microwave, warm the butter and milk together until the butter melts and the mixture is hot but not boiling. Warm dairy blends better into the potatoes.
- Mash the potatoes: Using a potato masher or ricer, mash the potatoes in batches for smoothness. Avoid using a food processor or blender, which can make potatoes gluey.
- Mix in dairy: Gradually add the warm butter and milk mixture to the mashed potatoes, stirring gently until fully incorporated and creamy. Add sour cream or cream cheese here if using, and mix until smooth.
- Season and adjust: Taste and season with additional salt and pepper as needed. For richer flavor, you can fold in a little extra butter or cream.
- Keep warm until serving: Transfer mashed potatoes to a large slow cooker set to “warm” or a heatproof serving dish covered with foil. Stir occasionally to maintain creaminess and prevent skin formation.
Tips
- Potato choice matters: Yukon Golds offer a buttery flavor and creamy texture without needing excessive butter. Russets yield fluffier, lighter mashed potatoes but may require more butter and cream.
- Don’t overmix: Overworking potatoes releases starch, causing a gluey texture. Mash gently and stop as soon as smooth.
- Make ahead: Mashed potatoes can be prepared up to 24 hours ahead. Store in an airtight container in the fridge and gently reheat with a splash of milk or cream to restore creaminess.
- Substitute dairy: For dairy-free options, use olive oil or a plant-based butter substitute and unsweetened almond or oat milk warmed before mixing.
Serving Suggestions
Mashed potatoes are a versatile side that pairs beautifully with roasted meats like turkey, chicken, beef, or pork. They also complement vegetarian dishes such as mushroom gravy, roasted vegetables, or lentil loaf. For a classic holiday spread, serve alongside green beans, cranberry sauce, and stuffing. Garnish with chopped fresh herbs like parsley or chives for a pop of color and freshness.
Variations
To customize mashed potatoes for different tastes or occasions, try these variations:
- Garlic Mashed Potatoes: Boil whole garlic cloves with the potatoes or sauté minced garlic in butter before adding to the mash.
- Cheesy Mashed Potatoes: Fold in shredded sharp cheddar, Parmesan, or Gruyère cheese just before serving for a rich, flavorful twist.
- Herb-Infused Mashed Potatoes: Mix in fresh herbs such as rosemary, thyme, or dill for an aromatic boost.
- Loaded Mashed Potatoes: Add crisp bacon bits, sour cream, shredded cheese, and green onions for a fully loaded version.
Storage and Reheating
Storage: Store leftover mashed potatoes in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze mashed potatoes in freezer-safe containers or heavy-duty freezer bags for up to 2 months.
Reheating: Reheat refrigerated mashed potatoes gently on the stovetop over low heat, stirring frequently and adding a splash of milk or cream to restore moisture. Alternatively, microwave in a covered dish, stirring every 1-2 minutes until heated through. For frozen mashed potatoes, thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I prepare mashed potatoes a day ahead for a large gathering?
Yes, preparing mashed potatoes a day ahead is convenient and can save time on the event day. Store them in an airtight container in the refrigerator. Reheat gently with added milk or butter to maintain creamy texture.
How do I keep mashed potatoes warm without drying out?
Using a slow cooker set to the “warm” setting is ideal for keeping mashed potatoes hot and moist. Stir occasionally and add a splash of milk or cream if they start to dry. Covering the potatoes tightly with foil also helps retain moisture.
What’s the best potato to use for mashed potatoes?
Yukon Gold potatoes are preferred for their natural buttery flavor and creamy texture, requiring less butter and cream. Russet potatoes yield fluffier mashed potatoes but may need more fat to avoid dryness. Avoid waxy potatoes like red potatoes, which can be gummy when mashed.
Can I make mashed potatoes without dairy?
Absolutely. Substitute butter with olive oil or dairy-free margarine, and use plant-based milks like almond, oat, or soy milk warmed before mixing. Adding roasted garlic or herbs can enhance flavor without dairy.
How do I avoid lumpy mashed potatoes when making a large batch?
Cut potatoes into uniform chunks to ensure even cooking, and mash them while still hot for smoother texture. Using a potato ricer or food mill can help achieve lump-free potatoes without overworking the starch.
Is it better to peel potatoes before boiling for mashed potatoes?
Peeling is optional but depends on preference. Yukon Gold skins are thin and add texture and nutrients if left on. Russets have thicker skins, which are usually peeled for a smoother mash. If leaving skins on, wash potatoes thoroughly before cooking.
With these guidelines and tips, you’ll be well-equipped to make creamy, delicious mashed potatoes that satisfy a crowd, no matter the occasion.
