Common Questions
How many asparagus spears per bundle?
4 to 6 spears per bacon slice is the sweet spot for average thickness asparagus. Use 3 to 4 spears for very thick spears, or 6 to 8 for skinny spears. What you are aiming for is one snug layer of bacon around the bundle with just a small overlap.
How much bacon do I really need?
For 1 lb of asparagus (about 20 to 28 spears), you will usually make 4 to 7 bundles. That means you need 4 to 7 slices of bacon if you use one slice per bundle. I call for 7 slices so you have enough even if your bundles run smaller or you have a few spears that need their own cozy bacon jacket.
Should I use a rack or a sheet pan?
Rack is best if you want crisp bacon all around and less greasy bottoms. If you only have a sheet pan, that’s fine. Just flip the bundles once halfway through and pour off excess fat carefully if it pools.
How do I keep the asparagus ends from burning?
- Trim the woody bottoms (usually 1 to 2 inches).
- Toss the spears lightly in oil before wrapping.
- Keep the exposed ends toward the center of the pan, not right up against the hot edges.
- Do not overbake. Pull them when the bacon is crisp and the asparagus is bright and just tender.
Do I need to pre-cook the bacon first?
Usually no. At 425°F, regular-cut bacon crisps up nicely without pre-cooking. If your bacon is very thick-cut, you can partially cook it for 3 to 5 minutes in a skillet just to get it started, then wrap and roast.
Should I blanch the asparagus first?
Nope. Roasting is enough. Blanching can make the bundles slippery and makes it harder for the bacon to stay snug.
Can I prep bacon-wrapped asparagus ahead of time?
Yes. Wrap the bundles up to 8 hours ahead, place on a parchment-lined tray, cover, and refrigerate. Bake straight from the fridge, adding 2 to 4 minutes to the cook time.
