1 pound bacon, chopped
8 medium potatoes (about 3 pounds), peeled and cut into 1/2-inch pieces
1 large onion, chopped
1 teaspoon salt
1/2 teaspoon pepper
In a large skillet, cook chopped bacon over medium-low heat until crisp. Remove bacon from pan with a slotted spoon; drain on paper towels. Reserve the bacon drippings.
Working in batches, add 1/4 cup bacon drippings, potatoes, onion, salt and pepper to pan; toss to coat. Cook and stir over medium-low heat until potatoes are golden brown and tender, 15-20 minutes, adding more drippings as needed. Stir in cooked bacon; serve immediately.
