Foil: Great for crispy bacon and easier clean-up. Just be careful; it can stick if you don't use a non-stick spray. Parchment Paper: Less stick, but might not give you that ultra-crispy texture. So, if you're Team Crispy, foil might be your MVP. But if you're all about that easy-peasy clean-up and avoiding stickage, parchment paper is your go-to.
