Combine zest, pecans, butter and sugar. Cut dough into 12 pieces and roll each in nut mixture. Place pieces in greased 9-by-5-inch loaf pan, loosely cover and let rise, about 1 hr.
Bake at 375°F until cooked through, 30 to 35 min. Cool in pan 15 min, then transfer to cooling rack.
Notes
You want to make sure the dough is completely thawed before working with it. Frozen spots make it really hard to roll, form and work with.
Before baking it you’ll want it to be fully risen. It takes a while because it starts out so cold (frozen in fact). But you’ll know it's fully risen when it is doubled in size.
