This batch of Instant Pot mashed potatoes has been my go to for family gatherings and weeknight dinners ever since I first adapted it for busy holiday prep. I discovered this combination the first time I had to feed a crowd while juggling a roast and two casseroles. The pressure cooker does the heavy lifting so the potatoes steam perfectly every time and the dairy additions melt into a luxuriously smooth texture. These potatoes are rich but balanced; the cream cheese gives them silkiness while the half and half and heavy cream round everything out without turning the dish overly heavy.

I use Yukon Gold because their naturally buttery flavor and lower starch give a dense, creamy final texture that holds up well under mashing. This version yields a large potful that will serve a family of eight to ten, and it reheats beautifully for leftovers. Beyond taste and texture, I love how predictable the method is the first time you try it; the Instant Pot removes the guesswork of when the potatoes are perfectly tender and saves stove top space during big meals.

Ingredients

• 5 lb Yukon Gold potatoes: Choose firm, even colored potatoes without green spots. Yukon Golds provide a naturally buttery taste and a creamy texture when mashed. If you find smaller tubers, count on roughly eight to ten medium potatoes to reach 5 lb.
• 2 1/2 tsp kosher salt: Divided use improves seasoning control. Use a brand like Diamond Crystal for lighter saltiness or Morton if you prefer denser crystals. One teaspoon is used in the cooking liquid, the rest is folded into the finished mash.
• 2 sticks salted butter: Use real butter for the best flavor. Two sticks equals one cup and provides richness and sheen when folded into hot potatoes. Add extra pats for serving if desired.
• 12 oz cream cheese: Full fat cream cheese melts into a silky texture that binds the mash without thinning it. Soften at room temperature for easier incorporation.
• 1/2 cup half and half and 1/2 cup heavy cream: These two dairy elements control the final consistency. Half and half lightens without losing creaminess while heavy cream adds body and gloss. Warm briefly before adding to avoid cooling the potatoes.
• 1/2 tsp seasoned salt: A pinch of flavored salt like Lawry's introduces a subtle savory note and complements the butter and cream cheese.
• 1 tsp black pepper: Freshly ground for best aroma. Add more when serving to taste.

Instructions

Prepare the potatoes:Add the peeled and quartered Yukon Gold potatoes to a 6 quart or 8 quart Instant Pot. Pour in 1 1/2 cups water and add 1 teaspoon of the kosher salt. Lock the lid and set the steam release valve to sealing. Select the pressure cook or manual high pressure function and set the timer to 10 minutes. Note that it will take some time for the cooker to build pressure before the timed countdown begins; that build up typically adds 8 to 12 minutes depending on pot size and initial water temperature.Pressure cook and release:When the cook time finishes, perform a quick release by carefully turning the steam valve to venting using a long handled spoon to protect your hands. Steam will escape rapidly so keep faces and hands away. Wait until the float valve drops and the lid unlocks, then open the lid away from you to avoid residual steam. If you see water pooled in the bottom of the insert, lift the inner pot and drain it into the sink to avoid watery mash.Drain and let steam escape:Return the drained potatoes to the pot insert and let them sit for a few minutes so excess steam escapes. This step prevents the mash from becoming gluey by eliminating excess moisture. You can also spread them out slightly in the pot to cool for a minute for the same effect.Mash and enrich:Using a potato masher or a ricer for a very fine texture, mash the potatoes while they are hot. Add the softened cream cheese and the sticks of butter in pieces so they melt quickly. Pour in the half and half and heavy cream warmed slightly, then add the seasoned salt, the remaining 1 1/2 teaspoons of kosher salt, and the black pepper. Stir until fully combined and smooth. Taste and adjust salt and pepper as needed. If you prefer looser potatoes, add additional warmed half and half one tablespoon at a time until the desired consistency is reached.Finish and serve:Transfer the finished mash to a warmed serving dish. Top with extra pats of butter and a sprinkle of fresh ground black pepper. These potatoes are best served hot and will keep warm in a low oven for a short time if needed while other dishes finish.

Storage Tips

Store cooled mashed potatoes in airtight containers in the refrigerator for up to four days. For freezing, spoon portions into freezer safe containers leaving some headroom and freeze for up to three months. To reheat refrigerated portions, warm gently on the stove over low heat stirring frequently and add 1 to 2 tablespoons of warmed half and half per cup of potatoes to restore creaminess. For frozen portions, thaw overnight in the refrigerator then reheat using the same method. Avoid microwaving large cold lumps without stirring as heat can concentrate and separate the fats.

Ingredient Substitutions

If you need a lighter version, substitute the heavy cream with additional half and half or whole milk but reduce the quantity slightly to avoid a loose texture. Swap cream cheese for Greek yogurt for tang and protein but use less to keep the mash thick. For dairy free alternatives, use vegan butter and unsweetened almond milk with a small spoon of dairy free cream cheese substitute; texture will be a bit different but still satisfying. Golden potatoes can be replaced with russets for a fluffier result but expect a more starchy finish.

Serving Suggestions

Serve these mashed potatoes next to roasted turkey, beef pot roast, garlic herb chicken, or grilled sausages. Garnish with a pat of butter, chopped chives, or a drizzle of browned butter and a few cracked black pepper grains for contrast. For a holiday presentation, pipe warm mash into a buttered casserole dish and sprinkle with grated Parmesan then briefly brown under a hot broiler for texture.

Cultural Background

Mashed potatoes are a universal comfort food found in many culinary traditions. Yukon Gold varieties originated in Canada and were bred for their creamy texture and golden flesh. The addition of cream cheese is an American adaptation used to produce silkier mashed potatoes without heavy reliance on large volumes of cream. Pressure cooking taps into modern convenience while honoring the long tradition of mashed tubers as a hearty accompaniment to roasted meats and stews.

Meal Prep Tips

For meal prep, portion mashed potatoes into individual reusable containers for quick lunches or dinners. Reheat on the stovetop with a splash of warmed half and half and a pat of butter to revive the texture. If making ahead for a large gathering, prepare through the mash step the day before, refrigerate, then finish by warming gently and stirring in extra warmed cream on the day of service to refresh the texture.

These potatoes have earned a permanent place on my weekly rotation because they combine speed, predictable texture, and crowd friendly flavor. Try them once for a family dinner and you will find it easy to make them again and again.
