Prep your asparagus by washing and cutting the dry ends off (this is optional I guess, but it's just how I prep them). Remove excess water by patting them dry with a clean tea towel.
Wrap your bacon firmly around your asparagus. The bacon will shrink while cooking and cling to your asparagus spears.
Cook for approximately 15 - 18 minutes. Cooking time will vary depending on the thickness of your bacon. I try to use the thinnest cuts of bacon so that my asparagus doesn't overcook while waiting for the bacon to cook.
