Step-by-Step Instructions

Step 1: Prep the Potatoes

Peel the potatoes and cut them into uniform 1-inch cubes. Keeping them the same size ensures they cook evenly under pressure. Tip: Yukon Golds give naturally buttery golden mash while Russets give a fluffier lighter texture. Both work beautifully.

Step 2: Add to Instant Pot

Place the potato cubes into the Instant Pot insert. Pour in 1 cup of water or chicken broth. Season with 1 tsp salt. Pro Tip: Using chicken broth instead of water adds a subtle savory depth to the potatoes.

Step 3: Pressure Cook

Secure the lid and set the valve to Sealing. Select Manual or Pressure Cook on HIGH for 10 minutes. The pot will take about 8 to 10 minutes to come to pressure before counting down.

Step 4: Quick Release

Once cooking is complete, carefully perform a Quick Release by switching the valve to Venting. Wait for all steam to release before opening the lid. Safety Tip: Use a kitchen towel or spoon to flip the valve — never your bare hand.

Step 5: Drain Excess Liquid

Drain most of the cooking liquid, leaving just 2 to 3 tablespoons in the pot. This small amount of starchy liquid helps achieve the perfect creamy consistency.

Step 6: Mash and Season

Add butter pieces directly to the hot potatoes and mash until melted. Pour in warm cream gradually, mashing to your desired consistency. Season generously with salt and pepper. Key Tip: Warm your cream before adding — cold dairy makes potatoes gluey and dense.

Step 7: Serve Immediately

Transfer to a serving bowl. Create a well in the center and add a generous pat of butter. Top with fresh chives, cracked black pepper, and a pinch of flaky salt. Serve hot!

Common Mistakes to Avoid

• Overcooking the potatoes — waterlogged watery mash — stick to 10 minutes on HIGH
• Adding cold cream — gluey dense texture — always warm it first
• Over-mashing — activates too much starch and turns potatoes paste-like — stop when smooth
• Not seasoning enough — bland potatoes — season generously and taste as you go
• Skipping the butter — dry and flat result — do not hold back on the butter

---

Storing Tips

• Refrigerator: Store in an airtight container for up to 4 days
• Freezer: Freeze in portions for up to 3 months — thaw overnight in fridge
• Reheating: Reheat on the stovetop with a splash of cream or milk, stirring gently
• Microwave: Cover and microwave in 1-minute intervals, stirring between each

Tip: Add a thin layer of melted butter on top before storing to prevent a dry skin from forming.
