Step 1

Place the potatoes, water, and 2 teaspoons of salt in the bowl of the Instant Pot.

Step 2

Secure the lid on the Instant Pot and Pressure Cook on High for 12 minutes. Quick release the pressure, reserve ¾ cup of the potato cooking water, and drain.

Step 3

Return the potatoes to the pot and add the garlic, olive oil, butter, and the remaining 2 teaspoons sea salt. Use a potato masher to mash well. Add the reserved cooking water, ¼ cup at a time, and use a rubber spatula to fold and mash the potatoes until creamy. Stir in the remaining cooking water as needed to reach your desired consistency.

Step 4

Season with fresh black pepper and garnish with chives.
