The recipe for Olive Garden breadsticks is not provided by the company, but a copycat recipe posted by ABC News is made with flour, yeast, salt, butter and garlic. After baking, the breadsticks are topped off with butter and a garlic sprinkle.
In a small bowl, dissolve 2 tablespoons sugar and 3/4 teaspoon active dry yeast in 1 cup plus 1 tablespoon warm water. Allow the mixture to rest at room temperature for 5 minutes, during which time it becomes frothy.
Meanwhile, place 3 cups bread flour and 1 1/2 teaspoons salt into a mixing bowl. Use a stand mixer with paddle attachment or a wooden spoon to cut in 1/4 cup softened butter. Slowly add the yeast mixture into the bowl. If you are using a stand mixer, swap the paddle attachment for the dough hook, and knead for 10 minutes. Otherwise, knead the dough on a floured work surface for 10 minutes.
Put the dough into a container covered with a damp towel, and allow it to rest for 1 1/2 hours, or until the dough has doubled in size. Form 2-ounce segments, and roll them into 7-inch breadsticks. Place onto a lined baking sheet, cover, and allow them to rest for another 1 1/2 hours.
Preheat the oven to 400 degrees Fahrenheit. Bake for approximately 12 minutes. Brush each breadstick with melted butter, and sprinkle with garlic salt.
