A worldwide favorite for a reason

Mashed potatoes remain one of the most beloved side dishes in many cuisines because they are comforting, adaptable, and simple to make. Potatoes are versatile and nutritious: a good source of potassium, vitamin C, fiber, and a small amount of protein. This Instant Pot method maintains flavor and texture while cutting down on active cooking time.

Ingredients

• 4 pounds Yukon Gold potatoes, peeled and cut into 1-inch pieces
• 6 cups water
• 4 teaspoons salt, divided
• 3 cloves garlic, grated
• 1/3 cup olive oil
• 1/4 cup unsalted butter
• Freshly ground black pepper to taste
• Chives, chopped for garnish

How to Make Instant Pot Mashed Potatoes

Step 1: Place the peeled and cut potatoes, the water, and 2 teaspoons of salt into the Instant Pot.

Step 2: Close and lock the lid. Set the Instant Pot to Pressure Cook (High) for 12 minutes. When the cooking time ends, perform a quick pressure release.

Step 3: Carefully reserve 3/4 cup of the cooking water, then drain the potatoes in a colander.

Step 4: Return the drained potatoes to the pot. Add the grated garlic, olive oil, butter, and the remaining 2 teaspoons of salt.

Step 5: Mash the potatoes with a potato masher until smooth. Gradually stir in the reserved cooking water a little at a time until you reach the desired consistency. The starchy cooking liquid helps create a silky texture without thinning the potatoes too much.

Step 6: Taste and adjust seasoning with freshly ground black pepper. Garnish with chopped chives and serve warm.

FAQs & Tips

How do I prep and store these mashed potatoes?

You can make these mashed potatoes ahead of time. The Instant Pot also keeps food warm for a while if you plan to serve later. Leftovers cool to room temperature, then store in airtight containers in the refrigerator for up to five days. For longer storage freeze in suitable containers for up to three months.

How can I reheat cold mashed potatoes?

Reheat gently on the stovetop in a sauté pan over low heat with a splash of milk or water and a pat of butter. Stir frequently to prevent sticking and to restore a smooth texture. You can also reheat in the oven or microwave, covering and stirring occasionally.

Is there a way to guarantee lump-free mashed potatoes?

For completely smooth mashed potatoes, press the cooked potatoes through a fine-mesh sieve or use a potato ricer before folding in the butter and liquids. This produces a silky, lump-free texture every time.

Can I use salted butter instead of unsalted?

Yes. If using salted butter, reduce the added salt slightly and taste as you go to avoid over-salting.

Serving Suggestions

These Instant Pot mashed potatoes are excellent as a simple side, garnished with chives, or transformed into loaded mashed potatoes with toppings like sour cream, bacon, shredded cheddar, or fried garlic. For herb-forward variations, add fresh dill, thyme, or oregano. You can also substitute some or all of the water with low-sodium chicken stock for extra flavor.

Mashed potatoes pair beautifully with roast beef, steak, brisket, roasted chicken, or hearty vegetarian mains. They also make a lovely base for saucy dishes and gravies.
