Why Make Mashed Potatoes in an Instant Pot?
The Instant Pot isn’t just another kitchen gadget; it’s a powerhouse for efficiency and flavor, especially when it comes to mashed potatoes. Here’s why it’s become our absolute favorite method:
- Unbeatable One-Pot Convenience: Forget juggling multiple pots and a colander. From cooking the potatoes to mashing them and incorporating the luscious finishing touches, everything happens right in the Instant Pot. This significantly cuts down on cleanup time, leaving you more moments to enjoy your meal and less time scrubbing dishes.
- Lightning-Fast & Efficient: Imagine going from raw potatoes to perfectly mashed in just 30 minutes! This recipe accounts for both prep and cook time for about 1 kg (2 pounds) of potatoes. The pressure cooker accelerates the cooking process dramatically, making it perfect for busy weeknights or when you need a quick yet impressive side dish.
- Infused Garlic Flavor: One of the secret weapons of this recipe is cooking the garlic right alongside the potatoes. The high-pressure environment tenderizes the garlic to an exquisite softness, allowing its savory essence to thoroughly infuse every potato piece. This results in a harmonious, deep garlic flavor that’s never overpowering.
- Simple, Accessible Ingredients: You won’t need any exotic items for this recipe. It relies on everyday pantry staples – potatoes, garlic, butter, milk, sour cream, and cream cheese – ensuring that these decadent mashed potatoes are always within reach.
No Instant Pot? No problem! You can still enjoy amazing mashed potatoes. Try our comforting Slow Cooker Mashed Potatoes or the classic Stovetop Garlic Mashed Potatoes.
Choosing the Best Potatoes for Mashing
The type of potato you choose plays a crucial role in the final texture of your mashed potatoes. For the ultimate creamy and fluffy results, starchy potatoes are your best friend. These varieties break down easily when cooked, making them ideal for a smooth mash.
- Yukon Gold Potatoes: Widely celebrated for their naturally buttery flavor and creamy texture, Yukon Golds are a top choice. They have a medium starch content, yielding a mash that is both rich and fluffy without being gummy. If you can find them, they are highly recommended.
- Russet Potatoes (Baking Potatoes): These are another excellent option due to their high starch content and low moisture. Russets produce light, fluffy, and absorbent mashed potatoes, perfect for soaking up all the butter and cream. They are readily available in most regions.
- Older Potatoes vs. New Potatoes: For best results, lean towards older, mature potatoes rather than “new potatoes” (young potatoes that are freshly harvested). New potatoes tend to have higher water content and waxy texture, making them harder to mash evenly and often resulting in a more gluey consistency. Older potatoes, on the other hand, have a lower moisture content and a higher starch concentration, which is exactly what you want for a wonderfully creamy mash.
- Prepping Your Potatoes: Regardless of the type, ensure your potatoes are peeled and cut into roughly 1-inch (2.5 cm) pieces. Uniformity in size is key for even cooking in the Instant Pot, preventing some pieces from being undercooked while others are overcooked. If you’re prepping ahead, you can peel and cut your potatoes and store them submerged in cold water in the refrigerator for a few hours. This prevents oxidation and keeps them from turning brown.
Simple Ingredients for Stellar Flavor
Despite their gourmet taste, these Instant Pot Garlic Mashed Potatoes require a surprisingly short and straightforward ingredient list. Quality ingredients, even simple ones, truly shine in this recipe:

Instant Pot Garlic Mashed Potatoes – Step-by-Step Guide
Get ready to create the quickest, most effortlessly creamy mashed potatoes you’ve ever made. Once you try this method, you’ll wonder why you ever did it any other way!

- Combine Ingredients: In the inner pot of your Instant Pot, add the peeled and evenly cut potatoes, whole peeled and smashed garlic cloves, water (or chicken stock for extra flavor), salt, and half of the butter (1.5 tablespoons). Ensure the potatoes are mostly submerged but not drowned; the small amount of liquid is key to the “no-drain” technique.
- Pressure Cook to Perfection: Secure the lid on your Instant Pot, making sure the sealing ring is properly in place. Turn the steam release valve to the “Sealing” position. Cook on high pressure (Manual or Pressure Cook setting) for 8 minutes. Depending on your Instant Pot model and potato quantity, it may take 5-10 minutes for the pot to come to pressure. Once the cooking cycle is complete, immediately perform a quick release by carefully turning the steam release valve to “Venting.” Allow all the steam to escape before opening the lid.
- The First Mash: With the cooked potatoes still in the Instant Pot liner and the residual liquid, begin mashing using a sturdy potato masher. The potatoes will be incredibly tender, and the garlic will practically dissolve. For extra fluffy mashed potatoes, you can carefully drain the liquid before mashing, but for ultimate creaminess, we recommend our signature no-drain method (explained further below).
- Enrich with Dairy: Once the potatoes are mostly mashed, add the remaining butter, sour cream, and cream cheese directly into the hot potatoes. The residual heat will help these ingredients melt beautifully.

- Mix Until Smooth: Mix thoroughly while the potatoes are still steaming hot. The warmth helps emulsify all the ingredients, creating a velvety smooth texture.
- Add Warm Milk: Pour in 1/4 cup of hot milk. Don’t be alarmed if it seems like a lot at first; the starchy potatoes will eagerly absorb it, contributing to their luscious consistency without making them runny. Hot milk is preferred over cold as it helps maintain the potato’s temperature and prevents starch shock, which can lead to a gluey texture.
- Final Mix, Season, & Serve: Give everything another good mix. Taste and adjust seasoning with more salt if needed. Serve immediately, topped with an extra pat of butter and a sprinkle of fresh chopped chives for an elegant finish.
- Optional Sieve for Ultra-Smoothness: For an exceptionally smooth, restaurant-quality mashed potato experience free of any tiny lumps, you can pass the mashed potatoes through a fine-mesh sieve or use a potato ricer. This step is entirely optional but guarantees a silkier texture.
The One-Pot, No-Drain Mashing Technique Explained
Our signature “no-drain” method for these Instant Pot Garlic Mashed Potatoes might seem a little unconventional, but it’s the secret to their incredible creaminess. Instead of completely draining the cooking liquid, we strategically add only 1/2 cup of water (or broth) for about 1 kilogram (2 pounds) of potatoes and then mash the potatoes directly in this residual liquid.
Here’s why this technique is a game-changer:
- Retaining Starch and Flavor: When potatoes boil, some of their natural starch and soluble flavors leach into the cooking water. By mashing them in this flavorful, starchy liquid, you reincorporate those elements, enhancing both the taste and the texture. This contributes to a deeper potato flavor and a naturally thicker, creamier consistency.
- Perfect Moisture Balance: The minimal amount of liquid ensures the potatoes have just enough moisture to mash easily without becoming dry or crumbly. As you mash, the starches in the potatoes absorb the liquid, creating a velvety smooth emulsion. Initially, the mixture might appear a bit thin, but as you continue mashing and stirring, it will thicken beautifully.
- Emulsification for Silkiness: When the hot dairy ingredients (butter, sour cream, cream cheese, and hot milk) are added to the still-warm, starchy potatoes, they emulsify with the residual cooking liquid. This process creates an incredibly smooth, almost whipped texture that feels like soft pillows of flavor on your palate. It’s a stark contrast to dry, lumpy mashed potatoes and delivers an almost effortless silkiness.
- True One-Pot Efficiency: Beyond the texture benefits, this method champions true one-pot cooking. No pouring hot water into a colander, no risk of burning yourself, and no extra dishes to wash. It’s streamlined, safe, and highly effective.
Mastering Mashed Potato Toppings & Add-Ins
While a simple dollop of butter and a sprinkle of fresh chives offer classic perfection, mashed potatoes are a fantastic canvas for culinary creativity. Here are some ideas to elevate your Instant Pot Garlic Mashed Potatoes to superstar status:
- Cheesy Delights:
- Cheddar: For a sharp, comforting flavor, mix in 1/4 to 1/2 cup of shredded sharp cheddar cheese while the potatoes are still hot. It will melt beautifully.
- Parmesan: Grated Parmesan adds a salty, umami depth. Stir in a few tablespoons or sprinkle generously on top just before serving.
- Cream Cheese & Sour Cream (Already in Recipe): These are already included for ultimate creaminess, but feel free to adjust amounts to your preference for extra tang and richness.
- Aromatic Herbs & Spices:
- Rosemary & Thyme: These earthy herbs pair wonderfully with potatoes. Finely chop fresh rosemary or thyme and stir into the mash, or sprinkle dried herbs at the end.
- Sage: For a more robust, slightly peppery note, a touch of fresh or dried sage can be transformative.
- Smoked Paprika: A pinch of smoked paprika can add a subtle warmth and smoky undertone.
- Savory & Decadent Add-Ins:
- Crispy Bacon Bits: Cooked and crumbled bacon adds a salty, smoky crunch that’s irresistible.
- Caramelized Onions: Slowly cooked, sweet caramelized onions offer a depth of flavor that complements the garlic beautifully.
- Roasted Garlic: While the recipe includes cooked garlic, for an even deeper, sweeter garlic flavor, you can roast extra heads of garlic until soft, then squeeze the pulp into the mash.
- Browned Butter: For a truly gourmet touch, melt butter in a saucepan over medium heat until it turns a nutty brown and smells fragrant. Drizzle this “liquid gold” over your finished mashed potatoes.
- Green Onions/Scallions: Similar to chives, thinly sliced green onions add a mild oniony bite and vibrant color.
- Protein & Vegetable Boosts:
- Cooked Chicken/Pulled Pork: Stir in shredded cooked chicken or pulled pork for a heartier, meal-in-one experience.
- Steamed Broccoli/Cauliflower: For added nutrition and texture, fold in small florets of steamed broccoli or cauliflower.

We’ve experimented with various garlic preparation methods – infusing garlic in oil, roasting it separately, or simply adding it raw to the Instant Pot. The Instant Pot method truly yields the most integrated and effortless garlic flavor. These incredibly creamy mashed potatoes are a perfect accompaniment to almost any main course, especially our perennial favorites like Herb Garlic Roast Chicken with Crispy Skin or, when time is of the essence, a succulent Spatchcock Chicken Roast.

Pro Tips and FAQs for Perfect Mashed Potatoes
Even with an easy recipe, a few extra tips can ensure your mashed potatoes are always flawless. Here are answers to common questions and additional advice:
- Can I prepare mashed potatoes ahead of time? Yes! Mashed potatoes can be made a day or two in advance. Store them in an airtight container in the refrigerator. To reheat, gently warm them on the stovetop over low heat, stirring frequently, adding a splash of milk or broth to restore creaminess. You can also reheat them in the Instant Pot on the “Keep Warm” setting with a little extra liquid, or in the microwave.
- How do I fix runny mashed potatoes? If your mashed potatoes are too thin, try letting them sit for a few minutes; sometimes, the starches just need a moment to fully absorb the liquid. If still too thin, you can add a tablespoon or two of potato flakes (instant mashed potato powder) or a thickener like cornstarch slurry (cornstarch mixed with a little cold water) and gently heat while stirring. Be careful not to overmix, which can make them gummy.
- How do I fix lumpy mashed potatoes? Lumps usually indicate unevenly cooked potatoes or insufficient mashing. For a quick fix, you can pass them through a fine-mesh sieve or use a potato ricer. Another option is to use an immersion blender or a stand mixer with the paddle attachment on low speed for a very short time, but be cautious as over-blending can develop too much starch and make them gluey.
- Why hot milk? Adding hot milk instead of cold prevents the potatoes from cooling down too quickly and helps the starches absorb the liquid more evenly. Cold milk can shock the starches, potentially leading to a gluey texture.
- Can I use vegetable broth instead of water? Absolutely! Chicken stock or vegetable broth (low sodium is best) can add an extra layer of savory flavor to your mashed potatoes. Just be mindful of the salt content in the broth and adjust the added salt accordingly.
- What if I don’t have cream cheese? While cream cheese adds a unique tang and richness, you can substitute it with an equal amount of sour cream or heavy cream for a creamy result.
- For a lighter version: You can reduce the amount of butter and cream cheese, or substitute some of the dairy with plain Greek yogurt for a slight tang and protein boost.

Ingredients
- 1 kg Potatoes, peeled and cut into even 1-inch pieces
- 6 Garlic Cloves, peeled and smashed
- 2/3 cup Water, or low-sodium Chicken Stock
- 3/4 teaspoon Salt (or to taste)
- 3 tablespoons Butter, divided
- 1/4 cup Sour Cream
- 1/4 cup Cream Cheese
- 1/4 cup Hot Milk
- More butter and chopped chives for topping (optional)
Instructions
-
In the inner pot of your Instant Pot, combine the peeled and cut potatoes, smashed garlic, water (or chicken stock), salt, and 1.5 tablespoons of butter. Close the lid, set the valve to “Sealing”, and cook on high pressure for 8 minutes. Once cooked, immediately perform a quick pressure release by turning the knob to “Venting”. Open the lid once the pressure has fully released.
-
Using a potato masher, mash the potatoes directly in the Instant Pot with the remaining liquid for incredibly creamy results. If you prefer a fluffier texture, you can drain the liquid before mashing. Once mashed, stir in the remaining 1.5 tablespoons of butter, sour cream, and cream cheese. Mix well until smooth while the potatoes are still steaming hot.
-
Pour in 1/4 cup of hot milk. Don’t worry if it looks like too much; the potatoes will absorb it beautifully, contributing to their luscious texture. Mix thoroughly again. Taste and adjust salt if needed. Serve immediately, garnished with more butter and fresh chopped chives if desired.
-
(Optional) For exceptionally smooth mashed potatoes, pass them through a fine-mesh sieve or use a potato ricer after mashing.
Notes
- For the fluffiest potatoes, use starchy varieties like Russet or Yukon Gold. While these might not be readily available everywhere, the recipe still yields awesome results with other suitable older potatoes.
- To prep potatoes in advance, peel and cut them, then keep them soaked in cold water in the refrigerator for a couple of hours. This prevents oxidation and discoloration.
- You can also use baby potatoes. No need to cut them, and you can even leave the skin on if you don’t mind the texture (ensure they are thoroughly washed). Adjust cooking time slightly if potatoes are very small.
- Chicken Stock or bone broth adds a fantastic depth of flavor. If using, opt for low-sodium versions and adjust the salt in the recipe as needed.
- Feel free to add your favorite herbs like rosemary, thyme, or a pinch of dried sage. You can stir them in with the dairy or sprinkle them on top for garnish.
