How to Make It
Preheat oven to 425°F. Place bacon on a microwavable plate lined with a paper towel and top with another paper towel. Microwave on HIGH until just beginning to crisp around edges, about 2 1/2 minutes. Remove from microwave, and cool 5 minutes.
Toss asparagus with oil, rosemary, salt, and pepper. Divide asparagus into stacks of 3, and tightly wrap each bundle with a piece of bacon. Place bundles on a wire rack set inside an aluminum foil-lined rimmed baking sheet. Bake in preheated oven until asparagus is tender and bacon is crispy, about 24 minutes. Serve immediately.
