Remove the baking sheet from the oven and let the asparagus roasts rest for 3–5 minutes; this lets the bacon firm up a bit so it’s easier to pick up. Transfer to a serving platter and serve warm. They’re best eaten the same day, but leftovers can be reheated in a hot oven or air fryer to re-crisp the bacon.
If you’re making these for a big watch party, you can prep them a few hours ahead: wrap all the asparagus in bacon, arrange on a baking sheet, cover, and refrigerate until you’re ready to roast. For slightly different textures, try using very thin asparagus for extra crisp spears, or medium-thick asparagus for more bite. If your bacon is very fatty, place the wrapped spears on a wire rack set over the baking sheet so the fat can drip away and the bacon crisps more evenly. You can also cut each bacon slice in half crosswise and use half a slice per spear for a lighter version—just wrap tightly and reduce the roast time by a few minutes. To stretch the recipe for more people, bundle 3–4 asparagus spears together and wrap them with a single slice of bacon to make “asparagus bundles” instead of individual spears. For those who don’t mind adding a third ingredient, a light sprinkle of black pepper or a dusting of grated Parmesan right before serving adds a nice twist, but the basic two-ingredient version is always the first to disappear.
