Onion Bread
Flavorful onion bread.

2 (.25 ounce) packages active dry yeast
3/4 cup warm water
2 cups scalded milk, cooled
3 tablespoons white sugar
2 1/2 teaspoons salt
3 tablespoons butter or margarine
6 1/4 cups all-purpose flour
1 (1 ounce ) package onion soup mix Directions:

1 In a large bowl, stir together yeast, warm water, and 1 teaspoon sugar. Set aside to proof.

2 Add milk, 2 2/3 tablespoons sugar, salt, butter or margarine, flour, and soup mix to the yeast in the bowl. Combine until dough forms, and then turn out on a lightly floured surface. Knead until dough is elastic. Oil a large bowl. Place the dough in the bowl, and turn several times to coat. Cover the bowl with a damp cloth, and set aside in a warm place to rise for 30 minutes.

3 Divide dough in half. Shape into loaves, and place into two greased 8 1/2 x 4 1/2 inch bread pans. Set aside to rise for 30 minutes.

4 Bake at 375 degrees F (190 degrees C) for 40 minutes. Loaf will sound hollow when done. Makes 2 - 1 1/2 pound loaves
