Melt the butter in a skillet over medium heat. Add the onion and cook, stirring occasionally, until softened and browned. Remove from heat and set aside.
3 tablespoons unsalted butter, 1 large onion
Add the water, softened butter, salt, sugar, potato flakes, flour, yeast, and cooked onions to a bread machine pan in the order recommended by the manufacturer. Select the dough cycle and start.
1 cup lukewarm water, 3 tablespoons unsalted butter, 1½ teaspoons salt, 3 tablespoons granulated sugar, ¼ cup instant potato flakes, 3 cups all-purpose flour, 2½ teaspoons active dry yeast
When the cycle is complete, transfer the dough to a lightly floured surface. Knead 6-8 times.
Divide the dough into 8 equal pieces. Shape into balls, then gently flatten into 4-inch circles. If the dough shrinks, let it rest for a few minutes and try again.
Place on a baking sheet. Cover loosely and let rise in a draft-free place for 40-45 minutes or until doubled in size.
Preheat oven to 350°F.
Whisk together egg white and water. Brush over the rolls.
1 large egg white, 1 tablespoon water
Bake for 15-20 minutes or until golden brown.
Cool completely before slicing.
