There are so many great sauces for asparagus out there, it's really very subjective which one is "best." I think this is the best sauce for asparagus because it's so easy to make. I don't like complicated sauce recipes for side dishes — it's like making a side dish for my side dish! This simple garlic soy sauce for asparagus is so fast and easy to make, it takes hardly any time or energy at all. For me, that makes it the best!
