Ingredients

2 tablespoons butter
4 cloves garlic, sliced thin
2 tablespoons lemon juice
salt to taste
1/4 teaspoon ground black pepper
1 onion, thinly sliced
1 1/2 pounds asparagus, trimmed

Directions

Preheat Smoker to 240 degrees

In a small saucepan, melt the butter, stir in the garlic and cook over low heat for 10 minutes. Remove from the heat and mix in the lemon juice, salt, and black pepper.
Arrange the onions in the bottom of a large cast iron skillet. Place asparagus spears over the onions. Drizzle the butter and garlic mixture over the asparagus. Place the uncovered skillet on the grill of your preheated smoker. Close the smoker and cook the asparagus until tender, which is about 1 hour.
