Hello KitchenSaver88. Do not worry, a hard crust is a very common issue and it can easily be fixed for your dinner tonight.
Here are the most reliable methods to soften your bread crust:
1. The damp paper towel method: Wrap the loaf in a slightly damp paper towel, place it in a preheated oven at 350 degrees Fahrenheit for about 5 to 10 minutes, and the steam will soften the crust.
2. The brown paper bag trick: Lightly mist the crust with water, put the bread inside a clean brown paper bag, fold it closed, and leave it for a little while before serving.
I hope this helps save your hard work and your money!
