I don't think freezing works extremely well for asparagus. You never see it frozen in the stores. It can be canned or pickled, but I can't recall ever seeing it alone or included in any vegetable pack in the frozen food aisles. I could be wrong and just have not noticed it, but all I've noticed is canned and fresh. I'd never seen it pickled until recently and that was online. I tried pickling by cutting it into 1-1/2" to 2" pieces and putting it into pickling vinegar after the jar was emptied of regular pickles. It worked great. A jar that had pickled olives was very salty and that is my favorite. Another jar had pickled peppers and it is also good. Don't chill the asparagus before cutting and putting in the pickling, or if it is chilled, let it come to room temperature. Then put it into the pickle jar with some onion chunks and refrigerate. The warm asparagus will pull the pickling vinegar into it as it chills and will be ready to eat within 5-7 days. Of course, that's not the way you would pickle something for long-term storage, but if you have an abundance that needs to be attended to, you can pickle it and then enjoy it up to a couple of months. It's also great raw, just cut up into salads or dipped into your favorite ranch or onion dip.
BTW: Did you blanch before freezing? A quick blanch and chill in ice water afterwards could kill surface bacteria and still let the spears stay crisp. An online search suggests blanching and freezing. You might also try freezing fresh in the vacuum packs for short periods of time if you have a vacuum sealer.
