The best ramen is fresh ramen. I don't recommend storing an assembled bowl of ramen in the fridge to eat the next day. The toppings will get soggy and craggy. However, you can prepare the broth ahead of time and store it in the fridge for up to 3 days. The same goes for the chicken and ramen eggs. All you need to do is warm the broth on the stove, cook up some fresh noodles and add the toppings. You can also freeze the broth for up to 3 months, but of course, you can't freeze assembled ramen.
