Detailed Directions and Instructions
Potatoes
Place the peeled and halved potatoes in the Instant Pot. Add enough water to cover them completely, approximately 6 cups. Add 2 teaspoons of salt. Secure the lid and set the Instant Pot to the steam setting for 12 minutes. Once the cooking time is complete, perform a quick release of the steam. Drain the potatoes; they should be fork-tender.
Garlic Herb Butter
While the potatoes are cooking, melt the butter in a large skillet over medium heat. Add the garlic cloves and herb sprigs. Let them cook gently, allowing the butter to absorb the flavors, for about 10–15 minutes. Remove the garlic and herbs, reserving the infused butter.
Mash and Mix
Return the drained potatoes to the Instant Pot. Using a potato masher or the back of a wooden spoon, mash the potatoes to your desired consistency. Pour in the reserved garlic herb butter, add the cream cheese or sour cream, grated Parmesan cheese (if using), and the remaining 2 teaspoons of salt. Stir until all ingredients are well combined and the mixture is smooth. Taste and adjust seasoning with additional salt if necessary.

Consistency Adjustment
For a thinner consistency, add 1/4 to 1/2 cup of broth or milk.
Potato Size
