In a small bowl, stir together ½ cup warm water and yeast. Let stand until mixture is foamy, about 5 minutes.
Meanwhile, in a medium microwave-safe bowl, stir together cottage cheese, sugar, 2 tablespoons butter, and 1 teaspoon salt. Microwave on high in 15-second intervals, stirring between each, until mixture is warm to the touch.
In a large bowl, stir together yeast mixture, cottage cheese mixture, onion, rosemary, thyme, and egg. Gradually stir in flour just until a dough forms. Turn out dough onto a lightly floured surface, and knead 10 times.
Spray another large bowl with cooking spray, and place dough in bowl, turning to grease top. Cover and let rise in a warm, draft-free place (85°) until doubled in size, about 35 minutes.
Liberally spray a 9-inch cast-iron skillet with cooking spray. Punch down dough, and transfer to skillet. Cover and let rise in a warm, draft-free place (85°) until doubled in size, about 45 minutes.
Preheat oven to 350°.
Bake until golden brown, tenting with foil halfway through to prevent excess browning if necessary, about 45 minutes. Remove from oven; brush with remaining 1 tablespoon butter, and sprinkle with remaining ½ teaspoon salt. Serve immediately.
