Yes, asparagus can be eaten raw. It has a slightly sweet and vegetal flavor that goes well in salads or as a healthy snack. Just be sure to wash it thoroughly before eating.
Raw asparagus tastes best if you eat it within a day or two of buying it, but it can be stored in the fridge for up to a week. To store, simply place the asparagus in a plastic bag and put it in the crisper drawer of your fridge.
If you want to keep raw asparagus for longer than a week, you can blanch it. Blanching is a quick cooking method that stops the enzyme action that causes veggies to deteriorate. To blanch asparagus, simply drop the spears into boiling water for 1-2 minutes then remove and place in an ice bath. Once cooled, drain the water and store the asparagus in a freezer safe container for up to 6 months.
