Chef’s Pro Tips for Perfect Results

Don’t be surprised if you never go back to stovetop potatoes after this.

• Use russet potatoes for that fluffy, classic texture that soaks up all the buttery goodness.
• Cut potatoes into even chunks for even cooking under pressure.
• Warm the milk and butter before adding to the potatoes to keep them hot and smooth.
• Don’t overmix — mash just until smooth to avoid gumminess.
• Let the Instant Pot naturally release pressure for 5 minutes before quick releasing. This keeps the potatoes tender and not waterlogged.

Potato masher or ricer: For that smooth, lump-free finish.

Instructions for Making The Best Instant Pot Mashed Potatoes

This recipe makes mashed potatoes feel totally effortless. Here are the steps you’re going to follow:

1. Preheat Your Equipment: No need for actual preheating, but make sure your Instant Pot is plugged in and set to “Pressure Cook.”
2. Combine Ingredients: Add the potato chunks and garlic to the Instant Pot. Pour in 1 cup of water and sprinkle with 1 teaspoon of the salt.
3. Prepare Your Cooking Vessel: Seal the Instant Pot lid and set the valve to “Sealing.” Set to Pressure Cook on high for 10 minutes.
4. Assemble the Dish: After cooking, allow a 5-minute natural release, then carefully quick release the remaining pressure. Drain any excess water if needed.

Texture & Flavor Secrets

The Instant Pot softens the potatoes to perfection, making them easy to mash into a pillowy texture. Adding the butter and warm milk while the potatoes are still hot helps them absorb the richness better. The sour cream brings a tang that cuts through the richness, keeping every bite balanced.

Cooking Tips & Tricks

No need to overcomplicate things — these little moves make a big difference:

• Don’t skip warming your dairy. Cold milk and butter will cool down the mash.
• Use a ricer for the smoothest texture if you’re feeling fancy.
• Want a roasted flavor twist? Roast the garlic separately before mashing it in.
• Keep your Instant Pot on “Keep Warm” while you mash to hold the heat.

What to Avoid

Let’s keep this mash magical by dodging a few pitfalls.

• Overmixing. This leads to gluey, sticky potatoes.
• Too much liquid at once. Add slowly so you can control the consistency.
• Undercooked chunks. Cut potatoes evenly to avoid hard spots.
