To start, preheat your oven to its lowest temperature setting, usually around 150-200°F. Don't worry, we're not trying to cook the bread, just dry it out, so you don't need to crank up the heat. And trust me, you don't want to end up with a toast-crunch instead of dried bread!
Next, slice the bread into thin strips or cubes, depending on your desired level of crunchiness. The key is to expose as much surface area as possible, so the bread can dry out evenly. Think of it like a bread-spa day, where the bread gets to relax and lose all its excess moisture!
