Preheat grill to 450 degrees F or 232. Clean and prep the grill
In the meantime, wash the asparagus and remove the stem at the bottom where it breaks off easily or you can use a knife to trim.
(optional) Use a vegetable peeler or knife to peel the bottom 1/3 of the asparagus stalk. If your stalks are large you may want to do this to make sure they stay tender.
Toss asparagus well with olive oil, salt and pepper to taste.
Place asparagus directly on the grill facing in the opposite direction as the grates so that your asparagus do not fall through. You can also grill on a grill pan or use a vegetable grill grate for smaller diameter asparagus.
Grill larger asparagus for about 6-10 minutes directly on the grill. Turning halfway through the cooking process. It depends on the size of your asparagus and also it depends how you like your asparagus cooked. We like ours a little aldente but with a nice char so for us that was about 3-4minutes on each side until you can piece your fork into the asparagus easily.If you like your asparagus more well done, depending on the size of the asparagus, it can take up to 10 minutes. For smaller asparagus that you need to cook on a vegetable grill these can be done in 4-6 minutes.
Be sure to turn and check on your asparagus a couple of times during the cooking process and turn as needed. Some of the asparagus might get done first if they are smaller compared to the rest. You can take these off the grill or place on indirect area of the grill until the rest are done cooking.
Remove the best grilled asparagus off the grill and top with lemon zest and parmesan cheese. Enjoy!
Refrigerate leftovers in a sealed container up to 3 days. We do not recommend freezing leftovers as the thawing process can leave your asparagus mushy. No one likes mushy asparagus. Take Care
