Step 1

Place a baking sheet on the top rack of the oven; preheat to 425 degrees. Grease a 9-inch fluted tart pan with 1 tablespoon butter. Line the pan with the pizza dough, carefully pressing it against the sides; trim excess dough.

Step 2

Whisk the ricotta, cream and egg in a medium bowl. Mince enough green scallion tops to make 2 tablespoons; add to the ricotta mixture along with the parsley and dill. Season with pepper. Slice the remaining scallions into 1/2- to 1/4-inch pieces.

Step 3

Heat the remaining 2 tablespoons butter in a large skillet over high heat. Add the sliced scallions and 2 tablespoons water; cook until the scallions are tender and start to sizzle, about 3 minutes. Remove from the heat and add the ham. Spread all but a few tablespoons of the scallion mixture on the prepared crust. Pour in the ricotta mixture, then scatter the remaining scallion mixture on top.

Step 4

Bake the tart on the preheated baking sheet for 20 minutes, or until the crust is golden and the filling is set. Rest in the pan for 5 minutes, then remove and slice.
