Onion Soup Pull-Apart Bread

In skillet, heat olive oil, and sauté onions until golden and caramelized, about 20 minutes. Set aside. Preheat oven to 350 degrees F. In small bowl, mix broth and onion soup mix together, and set aside. Slice top of bread long-ways and then cross-ways, being careful not to cut loaf all the way through. Gently open cuts of loaf. Pour broth mixture all over and into bread, making sure mixture makes it into crevices. Then cover bread with cheese, pushing cheese deep into the cuts, as well. Move loaf to sheet pan, and bake for 20 minutes, until cheese is melted. Serve immediately.
