Preheat the smoker: Before you start this pellet grill asparagus, make sure to preheat your smoker with the lid closed for 15 minutes at 200 degrees F. This guarantees that your asparagus will cook evenly and absorb all the smoky flavor.
Trim the asparagus: Don't forget to trim the pale end off of the asparagus and discard. This part is usually tough and fibrous, and removing it will make your side dish more enjoyable to eat.
Smoke with butter: Combine lemon juice, butter and garlic paste in a small saucepan and place it in the smoker with the asparagus. Halfway through, brush the asparagus with this smoked butter. This will give your asparagus a rich, smoky, and buttery flavor.
