Koshari is not difficult to make, but it has a lot of parts. Each part is easy to do, but if you are in a hurry, it can get overwhelming. If you are making this for your first time, block off about 2 hours and 30 minutes to take your time. When you've made koshari a few times, you can cook it in less than 1 hour and 30 minutes. If you have made this meal a lot, you can get it down to an hour.
