Ingredients

Here’s what you’ll need to create these glorious mashed potatoes:

• 4 lbs russet potatoes, peeled and rinsed
• 1 ½ cups water
• 8 tablespoons unsalted butter, diced
• 4 garlic cloves, peeled
• 1 ½ cups half-and-half (or whole milk for a slightly lighter option)
• 2 teaspoons salt
• 1 teaspoon garlic powder
• ½ teaspoon black pepper
• ½ cup grated Parmesan cheese
• 2 tablespoons fresh chives, sliced, for garnish

Equipment Needed

• 6-quart or larger Instant Pot
• Wire rack or steamer trivet for the Instant Pot
• Potato masher
• Spatula
• Serving bowl

Instructions

This method leverages the speed and efficiency of the Instant Pot to achieve incredibly tender potatoes, which then form the perfect canvas for a rich, garlicky, and cheesy mash.

1. Prepare the Potatoes for Steaming: Begin by placing a wire rack or steamer trivet inside the bowl of your 6-quart or larger Instant Pot. Carefully arrange the peeled and rinsed russet potatoes on top of the rack. Aim to place them in a single layer as much as possible to ensure even cooking. Pour the 1 ½ cups of water into the bottom of the Instant Pot bowl, around the rack.

2. Pressure Cook the Potatoes: Securely lock the lid of your Instant Pot. Ensure the steam release valve is set to the “Sealing” position. Select the “Pressure Cook” or “Manual” setting and set the cook time for 20 minutes on high pressure.

3. Natural Pressure Release: Once the cooking cycle is complete, allow the pressure to naturally release for 10 minutes. This gentle release is crucial for tenderizing the potatoes. After 10 minutes, carefully manually release any residual steam by moving the valve to the “Venting” position. Be cautious of the escaping steam.

4. Drain and Set Aside: Once all the steam has dissipated, carefully open the lid. Using tongs or oven mitts, remove the potatoes and the rack from the Instant Pot and place them onto a plate. Set them aside for a moment.

5. Infuse the Milk with Garlic and Butter: Drain the water from the Instant Pot bowl. Return the empty bowl to the base of the Instant Pot. Set the Instant Pot to the “Sauté” function. Once the bowl is dry, add the 8 tablespoons of diced unsalted butter and the 4 peeled garlic cloves. Cook, stirring often, until the butter has melted and the garlic has just begun to brown. This process infuses the butter with a wonderful garlic essence.

6. Warm the Half-and-Half: Stir in the 1 ½ cups of half-and-half (or whole milk) into the butter and garlic mixture in the Instant Pot. Continue to cook, stirring gently, until the milk has warmed through. Do not bring it to a boil.

7. Mash the Potatoes: Turn off the Instant Pot’s sauté function. Return the cooked potatoes to the Instant Pot bowl, now filled with the warm, garlicky milk and butter. Using a potato masher, begin to mash the potatoes directly in the pot. Continue mashing until you achieve your desired level of smoothness. For an extra smooth texture, you can use an immersion blender at this stage, but be careful not to over-process, which can lead to gummy potatoes.

8. Season and Finish: Stir in the 2 teaspoons of salt, 1 teaspoon of garlic powder, and ½ teaspoon of black pepper. Next, add the ½ cup of grated Parmesan cheese. Give it a good stir to ensure everything is well incorporated.

9. Taste and Adjust: This is a crucial step for any chef! Taste the mashed potatoes and adjust the seasonings as needed. You might want a little more salt, pepper, or even a pinch more Parmesan depending on your preference.

10. Serve: Once the seasoning is perfect, the mashed potatoes are ready to be served. Serve warm, and for a final flourish and burst of fresh flavor, garnish with the 2 tablespoons of sliced fresh chives sprinkled over the top.

Expert Tips & Tricks

• Potato Choice: Russet potatoes are ideal for their fluffy texture when mashed. Avoid waxy potatoes like red or Yukon Gold if you’re aiming for the lightest, fluffiest mash.
• Garlic Intensity: For a milder garlic flavor, you can reduce the number of fresh garlic cloves or even omit them and rely solely on the garlic powder. For a more intense punch, you could roast the garlic cloves before adding them to the butter.
• Creaminess Control: The amount of liquid you add – the half-and-half and the butter – directly impacts the creaminess. Start with the recipe amounts, and if you prefer a looser mash, you can always stir in a little extra warmed half-and-half or milk after mashing.
• Butter Matters: Using good quality unsalted butter will make a noticeable difference in the overall flavor of your mashed potatoes.
• Don’t Over-Mash: While you want them smooth, over-mashing potatoes, especially with a food processor or immersion blender, can break down the starches too much, resulting in a gummy texture. A good old-fashioned masher is often the safest bet for perfect texture.

Serving & Storage Suggestions

These Garlic Parmesan Mashed Potatoes are a wonderfully versatile side dish. They are the perfect accompaniment to roasted chicken, grilled steak, pork chops, or even a hearty vegetarian main course like lentil loaf. For an extra decadent touch, serve them alongside a rich gravy.

Storage: Leftover mashed potatoes can be stored in an airtight container in the refrigerator for up to 3-4 days. They tend to thicken as they cool.

Reheating: To reheat, gently warm them in a saucepan over low heat, stirring frequently. You may need to add a splash of milk or cream to restore their creamy consistency. Alternatively, you can reheat them in the microwave, stirring every minute or so. For a larger batch, a quick stint in a 350°F (175°C) oven, covered with foil, also works well.

Variations & Substitutions

• Dairy-Free/Vegan: For a dairy-free or vegan version, substitute the unsalted butter with a good quality vegan butter alternative and use a plain, unsweetened plant-based milk like almond or soy milk instead of half-and-half. Omit the Parmesan cheese or use a vegan Parmesan alternative.
• Herbal Boost: While chives are classic, feel free to experiment with other fresh herbs like parsley, dill, or even a hint of rosemary or thyme for a different flavor profile.
• Spicy Kick: Add a pinch of red pepper flakes to the butter and garlic mixture for a subtle spicy note.
• Cheesy Variations: Beyond Parmesan, consider adding a touch of sharp cheddar, Gruyère, or even cream cheese for an extra layer of richness.

FAQs (Frequently Asked Questions)

Q: Why use an Instant Pot for mashed potatoes?
A: The Instant Pot cooks potatoes quickly and evenly under pressure, resulting in very tender potatoes that are easy to mash and absorb flavors beautifully. It also frees up stovetop space, which is a lifesaver during busy meal prep.

Q: Can I use other types of potatoes?
A: While russets are highly recommended for their fluffy texture, Yukon Golds can be used for a slightly creamier, richer mash, though they may not be as light. Avoid waxy potatoes.

Q: How do I make the mashed potatoes smoother if I don’t have an immersion blender?
A: A sturdy potato masher works well. For an extra smooth texture without a blender, you can pass the mashed potatoes through a ricer after mashing them initially.

Q: Can I make this recipe ahead of time?
A: You can cook and mash the potatoes ahead of time and refrigerate them. When reheating, you will need to add liquid and gently reheat, as they will thicken considerably.

Q: My mashed potatoes seem a bit dry. What can I do?
A: You can stir in a little extra warmed half-and-half, milk, or even melted butter until you reach your desired consistency.
