Aee results just as good with precooked bacon?

If you save bacon grease, use it with the Brussels sprouts.

Hello Jean! Since the sprouts and bacon brown simultaneously, there's more of a chance for the veggies to become infused with all that bacon-y goodness if it's uncooked—if you opt to go with precooked bacon, I'd recommend adding a little more oil to the sprouts during the cook time and then tossing in the bacon while everything's still warm, otherwise it'll likely become overly crisped. Hope that helps and have a lovely Thanksgiving!
