Ingredients
- 5 lbs Russet Potatoes: The best choice for fluffy, starchy potatoes.
- 1 cup Sour Cream: Full-fat is best for richness and moisture.
- 1 (8 oz) package Cream Cheese: Let it soften to room temperature. This is the magic ingredient!
- 1/2 cup Unsalted Butter: Cut into cubes for easy melting.
- 1 cup Milk or Half-and-Half: Whole milk or half-and-half will give you a creamier result.
- 1 tbsp Kosher Salt: Or to taste. Don’t be shy with the salt!
- 1/2 tsp White Pepper: Use white pepper to avoid visible specks.
- Optional: Fresh chives or parsley for garnish.
Substitutions:
- Sour Cream: Greek yogurt or crème fraîche works in a pinch for a similar tang.
- Butter: Salted butter is fine, just reduce the added salt.
- Milk: Heavy cream will make them unbelievably decadent.
Tools & Kitchen Gadgets Used
- Large stockpot: For boiling the potatoes.
- Colander: To drain the cooked potatoes.
- Potato masher or ricer: A ricer gives you the smoothest texture, but a masher works just fine.
- Large mixing bowl: For combining all the ingredients.
- Electric hand mixer or stand mixer: For a truly whipped, fluffy texture. This is a total game-changer.
- 9×13-inch baking dish: For storing and reheating.
- Aluminum foil: To cover the dish for storage and reheating.
- Measuring cups and spoons: The basics, but essential.
Step-by-Step Instructions
- Prep the Potatoes: First, peel your potatoes. Do not skip this step unless you’re into lumpy, skin-on potatoes (and who are we kidding, you’re not). Cut them into even 1-inch cubes. This ensures they cook at the same rate. You don’t want some mushy and some hard.
- Boil Them: Put the potato cubes in your large stockpot and cover them with cold, salted water. Bring the water to a boil, then reduce the heat to a simmer. Cook for about 15-20 minutes, or until you can easily pierce a potato with a fork. Don’t overcook them until they fall apart, but don’t undercook them either. You’ll know when they’re ready.
- Drain Thoroughly: This is a crucial step! Drain the potatoes in a colander. Let them sit for a couple of minutes to steam dry. Seriously, let that steam escape. We want fluffy potatoes, not watery ones.
- Get Mashing: Transfer the drained, hot potatoes to a large mixing bowl. Add the softened cream cheese, butter, sour cream, salt, and white pepper. Using an electric mixer on low speed, start to beat everything together. If you’re using a masher, get to it! Mash until everything is mostly combined.
- Add the Dairy: Gradually add the milk or half-and-half while continuing to mix on medium speed. Beat the potatoes until they are smooth, creamy, and ridiculously fluffy. Don’t overmix, or you’ll end up with a gluey mess. We’re aiming for a heavenly cloud, not wallpaper paste.
- Transfer & Cool: Scrape the potatoes into a greased 9×13-inch baking dish. Smooth the top with a spatula. Let them cool completely to room temperature. This is important before you put them in the fridge.
- Cover & Refrigerate: Once cool, cover the dish tightly with aluminum foil and place it in the fridge. You can do this up to three days in advance. See? Your future self is already thanking you.
Reheating Instructions
On the big day, take the dish out of the fridge an hour before you want to serve them. Preheat your oven to 350°F (175°C). Pop the covered dish in the oven for about 30-40 minutes, or until they are heated all the way through. You can also give them a quick stir halfway through. If they seem a little dry, stir in a splash of milk. And if you’re feeling extra, uncover them for the last 5-10 minutes to get a slightly golden top.

Common Mistakes to Avoid
- Using the Wrong Potato: Don’t use waxy potatoes like red potatoes. They don’t absorb the dairy and will give you a gluey, sad consistency. Russets are your best bet for a fluffy, light mash.
- Not Salting the Water: You must salt the water you boil the potatoes in. It seasons them from the inside out. Skipping this step means your potatoes will taste bland no matter what you add later. It’s a flavor foundation.
- Over-boiling the Potatoes: If you cook them until they are mushy and falling apart, they’ll get waterlogged. You’ll have a hard time getting a good texture. Check them with a fork—if it slides in easily, they’re done.
- Over-mixing: The number one sin of mashed potato making. Overworking the potatoes releases too much starch, turning them from a fluffy cloud into a sticky, gummy mess. Use a hand mixer or masher and stop as soon as they’re smooth.
- Putting Hot Potatoes in the Fridge: Letting them cool completely before covering and refrigerating is key. Trapped steam will create condensation, making your potatoes soggy. Gross, right?
Variations & Customizations
- Garlic & Herb Mashed Potatoes: Roast a head of garlic, squeeze out the cloves, and mash them in with the potatoes. Or add 1-2 cloves of minced garlic to the potatoes after mashing. You can also throw in some chopped fresh rosemary and thyme.
- Loaded Mashed Potatoes: Who doesn’t love this? Mix in some crumbled bacon, shredded cheddar cheese, and sliced green onions or chives after mashing. Serve with an extra dollop of sour cream on top.
- Vegan/Dairy-Free Mashed Potatoes: Swap the butter for a good quality vegan butter. For the cream cheese and sour cream, use cashew cream or your favorite store-bought vegan alternatives. Use unsweetened almond milk or oat milk for the liquid.
FAQ Section
1. Can I make mashed potatoes ahead of time? You bet your boots you can. This recipe is specifically designed to do just that. You can make them up to three days in advance.
2. How do you reheat pre-made mashed potatoes? The oven is your best friend here. Cover the dish with foil and bake at 350°F for about 30-40 minutes. The foil keeps the moisture in.
3. Do you add butter and milk to mashed potatoes at the same time? You can, but I recommend adding the solid fats first (butter, cream cheese, sour cream) and getting them well-mixed. Then, add the milk or half-and-half gradually until you reach your desired consistency. This gives you more control.
4. Why are my mashed potatoes so gummy? You probably over-mixed them. When you beat potatoes too much, the starch molecules break down and create a gluey, sticky texture. Use a ricer or a hand masher, and don’t be tempted to use a food processor.
5. How do you fix runny mashed potatoes? Gently heat them in a pot on low heat while stirring continuously. This evaporates some of the excess liquid. You could also add a spoonful of potato flakes or a little cornstarch mixed with water, but be careful not to overdo it.
6. Should I peel the potatoes before boiling? Yes, for this recipe, you should. We’re aiming for a super smooth, fluffy texture. Leaving the skin on works for a rustic mash, but not for this creamy delight.
7. How long can you keep make-ahead mashed potatoes in the fridge? They will keep well for up to three days in the fridge when stored in a tightly covered container. After that, the texture can start to get a little weird.
