Preheat the oven to 350 degrees. Cook the dry elbow pasta in a pot for about 10 minutes or until soft. Pour the cooked pasta in a baking pan. Sprinkle cheese and cooked bacon over the pasta. Place the pasta in the oven, and cook for about 45 minutes or until the pasta is crispy. Once ready, remove the pasta from the oven and let sit for 10 minutes before serving.
