Cheesy Mashed Potatoes with Green Chile

golden yellow potatoes (russets would work as well, peeled and then chopped into approximately 2" pieces)

butter (soft)

heavy cream or milk (adjust the amount according to the creaminess and thickness that you prefer, milk works fine for this, the cream simply creates a more decadent dish)

chopped green chiles

kosher salt (divided)

freshly cracked pepper (to taste)

granulated garlic (garlic powder works as well)

shredded cheddar cheese
