Contrary to popular belief, asparagus must not be cooked before eating. In fact, it can be a nutrient-dense supplement to your diet when eaten without cooking. However, the stiff plant fibers in asparagus get softer when boiled, facilitating simpler chewing and digestion. 

Raw asparagus may be as flavorful and easy to eat as cooked when prepared correctly. 

How To Eat Raw Asparagus?

First, trim the spears of their woody ends, just like you would if preparing to cook them. You could bite right into them now, but it wouldn’t be enjoyable. So, chop or shred the spears into small pieces using a vegetable peeler, grater, or sharp knife.

Once smaller pieces are made, asparagus becomes easy to eat raw. It can be added in salads to bring to the platter. 

However, if you are feeling raw asparagus too tight to chew and consume, boiling them is the next best choice for their consumption. Boiling makes the texture of asparagus soft and chewable. 

According to one study, boiling green asparagus resulted in a 16% increase in its overall antioxidant activity (2). In particular, it increased the amount of quercetin and beta carotene, two potent antioxidants, by 98% and 24%, respectively (3).

Another study shows cooked white asparagus has almost three times the antioxidant activity of raw asparagus (4).

Impact On Nutritional Value After Cooking

While cooking asparagus may increase the availability of some chemicals, it may also lessen the amount of other nutrients.

For instance, one study discovered that cooking green asparagus resulted in a 52% reduction in the vitamin C concentration, which is highly susceptible to heat (5). A few things that can influence the nutrients in any vegetable include the following-

  • the kind of nutrient
  • cooking method
  • length of heat exposure

Generally speaking, it’s best to use cooking techniques like steaming, sautéing, quick-blanching, and microwaving that minimize water and heat exposure. In addition, try to get a crisp-tender texture for your veggies rather than overcooking them.
