Instant Pot Mashed Potatoes: Ultra Creamy Recipe in 15 Minutes

Let me paint you a picture: you walk into your kitchen after a long day, and the earthy aroma of potatoes mingling with rich butter and a hint of garlic fills the air. It’s that unmistakable, homey scent that makes your stomach grumble and your mind wander back to childhood Sunday dinners. The best part? These Instant Pot mashed potatoes are ridiculously creamy, ready in just 15 minutes, and absolutely swoon-worthy.

The first time I whipped up mashed potatoes in my Instant Pot, I was honestly skeptical. Years ago, I’d spend ages boiling, mashing, and stirring my grandma’s recipe (she swore by her hand masher and a healthy dose of elbow grease). But with this method, I paused after my first taste—creamy, buttery, and cloud-like. It was the kind of moment where you pause, take a deep breath, and just smile because you know you’re onto something truly special.

When I was knee-high to a grasshopper, mashed potatoes were the star of every holiday meal. We’d fight over who got the biggest dollop, and my mom would always sneak extra cream in “just for luck.” Those warm memories are baked right into every spoonful of these Instant Pot mashed potatoes. My family couldn’t stop sneaking bites straight from the pot (and I can’t really blame them, honestly). Even my picky eater declared these “the best ever.”

You know what? These mashed potatoes are dangerously easy, pure nostalgic comfort, and perfect for everything—potlucks, weeknight dinners, or brightening up your Pinterest recipe board. I’ve tested this recipe more times than I care to admit (in the name of research, of course), and it’s become a staple for family gatherings, gifting, and, well, late-night cravings. It feels like a warm hug in a bowl, and you’re going to want to bookmark this one for sure.

What Ingredients You Will Need for Ultra Creamy Instant Pot Mashed Potatoes

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfyingly creamy texture—without fuss. Most are pantry staples, so you won’t need any special shopping trips. Here’s what you’ll need:

• Yukon Gold potatoes, peeled and cut into 1-inch chunks (2 lbs / 900 g) – Yukon Golds are my top pick for their naturally creamy, buttery flavor. Russets work too for a fluffier texture.
• Water, for pressure cooking (1 cup / 240 ml) – Just enough to steam the potatoes without diluting the flavor.
• Salt, kosher or sea salt (1 tsp / 5 g, plus more for seasoning) – Essential for bringing out the potato flavor.
• Unsalted butter, cut into cubes (4 tbsp / 56 g) – Adds richness and that classic mashed potato taste. I love using Kerrygold for extra flavor.
• Whole milk, warmed (½ cup / 120 ml) – Warm milk blends in smoothly. You can substitute with half-and-half or even cream for extra decadence.
• Sour cream, (¼ cup / 60 g) – Adds tang and extra creaminess. Greek yogurt is a fine swap for a lighter version.
• Garlic, minced (2 cloves) – Optional, but highly recommended for a subtle savory boost. Roasted garlic works beautifully if you have some on hand.
• Black pepper, freshly ground (½ tsp / 2 g) – For a gentle kick and depth of flavor.
• Chives or parsley, chopped (2 tbsp / 8 g, optional) – For garnish and a fresh pop of color.

Ingredient Notes:

• If you need a dairy-free version, use vegan butter and unsweetened oat or almond milk. Dairy-free sour cream works too.
If you want a lower-carb option, swap in half cauliflower (steamed) for half the potatoes.
• For extra flavor, try adding a splash of chicken broth instead of water. It’s my secret weapon for savory mashed potatoes.
• Prefer it extra buttery? Go ahead and bump up the butter to 6 tbsp (85 g)—no judgement here.

I recommend using organic potatoes when possible; they just taste better, honestly. If you’re cooking for a crowd, you can easily double this recipe—just make sure not to overfill your Instant Pot.

Equipment Needed

You don’t need much to make these Instant Pot mashed potatoes, but the right tools do make a difference. Here’s what you’ll want to grab:

• Instant Pot (6-quart or larger) – This is the star of the show! Any size works, but a 6-quart handles up to 4 lbs of potatoes comfortably.
• Potato masher or hand mixer – For mashing to your desired consistency. I use a stainless steel masher for chunkier potatoes, and a hand mixer for ultra-smooth results.
• Peeler – A sharp vegetable peeler makes quick work of the potatoes. My favorite is the classic Y-shaped kind.
• Measuring cups & spoons – You’ll want accuracy for the best texture.
• Large mixing bowl (optional) – If you prefer to mash them outside the Instant Pot, this is handy.
• Rubber spatula – Helps scrape every last bit of goodness out of the pot.

If you don’t have an Instant Pot, a stovetop pressure cooker works too (just adjust cook times). For mashing, a sturdy fork will do in a pinch—though your arm might get a workout! Hand mixers are great, but don’t overmix or the potatoes can turn gluey.

Maintenance Tip: Keep your Instant Pot’s sealing ring clean and odor-free by soaking in a baking soda solution. For budget-friendly options, I’ve found thrift store mixing bowls and peelers work just as well as fancy brands.

Preparation Method

Let’s get cooking! Here’s how you make ultra creamy Instant Pot mashed potatoes in 15 minutes, step by step:

1. Prep the potatoes: Peel 2 lbs (900 g) of Yukon Gold potatoes. Cut into even 1-inch chunks for faster, even cooking. (If you leave them bigger, they’ll need a few extra minutes.)
2. Add to the Instant Pot: Place the potatoes in the pot. Pour in 1 cup (240 ml) of water and sprinkle with 1 tsp (5 g) salt. Make sure the potatoes are spread out for even steaming.
3. Pressure cook: Secure the lid, set the valve to Sealing, and select Manual/Pressure Cook for 8 minutes. It takes about 5 minutes to reach pressure (so, yes, 15 minutes total!). While they cook, warm your milk and prep your butter.
4. Quick release: As soon as the timer beeps, carefully switch the valve to Venting for a quick release. Steam will shoot out—keep your face back! The potatoes should be fork-tender and steamy.
5. Drain excess water: Open the lid and check for excess water. If needed, drain off any liquid (Yukon Golds typically absorb most of it).
6. Mash it up: Add 4 tbsp (56 g) unsalted butter, ½ cup (120 ml) warmed milk, ¼ cup (60 g) sour cream, and 2 cloves garlic (minced). Mash with a potato masher for chunky potatoes or use a hand mixer on low for silky-smooth texture. (Don’t overmix—just until creamy!)
7. Season to taste: Stir in ½ tsp (2 g) black pepper and a bit more salt if needed. Taste and adjust seasoning—potatoes love salt!
8. Garnish and serve: Top with chopped chives or parsley for a burst of color. Serve immediately while piping hot.

Preparation Notes: If the potatoes seem dry, add an extra splash of milk. Too wet? Let them sit uncovered for a minute—the steam will evaporate. For extra flavor, try blending in roasted garlic or a drizzle of olive oil.

Troubleshooting Tips: If your potatoes turn gluey, it’s usually from overmixing. Mash gently and stop once they’re smooth. If you forgot to warm the milk, microwave it for 20 seconds—cold liquid can make the potatoes stiff.

Efficiency tip: Pre-peel your potatoes earlier in the day and keep them submerged in cold water. This saves time and keeps them fresh. I always set my butter out to soften while the potatoes cook—it makes mashing so much easier!

Cooking Tips & Techniques

Over many mashed potato trials (and a few kitchen disasters), I’ve picked up a handful of tricks that guarantee creamy, dreamy results every time.

• Choose the right potato: Yukon Golds make the creamiest mashed potatoes. Russets work, but you’ll get a lighter texture. Red potatoes are waxier—good for rustic mash but not ultra-creamy.
• Warm your dairy: Cold milk or cream can make potatoes stiff and less fluffy. Always warm your milk and butter before stirring them in. Trust me, it matters!
• Don’t overmix: This one’s huge. Overmixing releases starch and can turn potatoes gluey. Use a gentle hand, and mash just until smooth.
• Season early and often: Salt the cooking water and taste at the end. Potatoes soak up salt, so it’s better to start with less and add more as needed.
• Multitasking strategy: While the Instant Pot works its magic, prep your mix-ins (garlic, herbs, dairy) so you’re ready to go once the potatoes are done.
• Consistency secret: If you want extra creamy potatoes, add a splash of heavy cream or cream cheese. For lighter mash, stick with milk and sour cream.

Confession: one time, I tried to shortcut and use cold butter straight from the fridge. Let’s just say it didn’t melt well and there were weird lumps. Lesson learned—always let your butter soften!

If you’re serving a crowd, keep mashed potatoes warm by leaving them in the Instant Pot on “Keep Warm.” Add a splash of milk if they start to thicken. For perfect results every time, keep your eye on texture—creamy, not runny, and never gluey.

Variations & Adaptations

One of the best parts about Instant Pot mashed potatoes? They’re super adaptable. Here are a few ways you can make this recipe fit your needs, mood, or dietary preferences:

• Dairy-Free: Swap in vegan butter and unsweetened oat or almond milk. Use dairy-free sour cream for the same tangy finish. I’ve made this version for my lactose-intolerant cousin, and it’s still rich and fluffy.
• Garlic Parmesan: Stir in ½ cup (50 g) freshly grated Parmesan cheese and use roasted garlic instead of raw. Adds an Italian twist that’s a huge hit at dinner parties.
• Loaded Mash: Fold in crispy bacon bits, shredded cheddar, and sliced green onions. Makes a hearty, pub-style side (my husband’s favorite for game night).
• Low-Carb Variation: Substitute half the potatoes with steamed cauliflower florets before mashing. The texture is lighter, and it’s great for keto diets.
• Herb Mash: Mix in fresh rosemary, thyme, or dill for a garden-fresh flavor profile. Perfect for springtime meals.

Cooking Method Adaptations:

• No Instant Pot? Boil potatoes on the stovetop until fork-tender, then mash as directed. Add a touch more milk to adjust texture.
• Want a rustic mash? Leave the skins on and mash lightly for a chunkier, more earthy feel.

Allergen Substitutions:

• For nut allergies, avoid almond milk—stick to oat or rice milk.
• For gluten-free, all ingredients are naturally safe, but always check labels on sour cream and butter.

Personal twist: I love adding a dollop of horseradish for a little heat on chilly winter nights. It’s not for everyone—but if you like a kick, try it out!

Serving & Storage Suggestions

For best results, serve these Instant Pot mashed potatoes piping hot, straight from the pot. Honestly, a warm bowl drizzled with melted butter and sprinkled with chives is pure magic.

• Serving temperature: Hot is best! If you need to hold them, use the Instant Pot’s “Keep Warm” function and stir in extra milk as needed.
• Presentation: Scoop into a serving dish, swirl with a spoon, and top with fresh herbs or a pat of butter. For Pinterest-worthy photos, use a wide bowl and garnish generously.
• Pairings: Mashed potatoes go with almost anything—roast chicken, turkey, beef stew, or grilled veggies. I love serving them alongside green beans or a crisp garden salad.
• Storage: Leftovers keep well in an airtight container in the fridge for up to 4 days. Stir in a splash of milk if they thicken.
• Freezer: Yes, you can freeze mashed potatoes! Cool completely, portion into freezer bags, and lay flat. Thaw overnight and reheat gently with added milk.
• Reheating: Microwave in 1-minute bursts, stirring between each, or gently warm on the stovetop. Add milk or butter to refresh the texture.

Flavor tip: Mashed potatoes get even tastier overnight as the flavors meld. They’re perfect for make-ahead holiday sides or busy weeknight leftovers!
