Peel and quarter the potatoes lengthwise, then cut into 1-inch wedges. Put in a heavy medium saucepan with 1 teaspoon of the salt and add enough cold water to cover by 1-inch. Bring to a boil over high heat. Reduce the heat to medium-low. Simmer until the potatoes are fork-tender, about 25 minutes.
Drain in a colander. Return the potatoes to the saucepan. Add the cream, butter, the remaining 3/4 teaspoon salt, and the pepper. With the heat on medium-low, mash and stir the mixture until well blended, 4 to 5 minutes. Mix in the blue cheese and parsley and mash to incorporate.
