In a large mixing bowl, combine the mashed potatoes, softened butter, and egg, stirring until the mixture is smooth and well incorporated.

Gradually add the flour and bread crumbs to the potato mixture along with salt to taste, mixing until a soft, slightly sticky dough forms.

Turn the dough out onto a lightly floured surface and knead gently for about 5 minutes until the dough becomes smooth and cohesive, adding small amounts of flour as needed to prevent sticking.

Shape the dough into a loaf and place it into a greased loaf pan, pressing it evenly to fill the pan.

Cover the loaf pan with a clean kitchen towel and allow the dough to rest and rise in a warm, draft-free location until noticeably puffed.

Preheat the oven to 375°F (190°C) while the dough completes its rise.

Bake the loaf in the preheated oven until the top is golden brown and the bread sounds hollow when tapped on the bottom.

Remove the bread from the oven and allow it to cool in the pan for 10 minutes before turning it out onto a wire rack to cool completely before slicing.
