In a large bowl, mix together the flour, brown sugar, raisins, yeast, and salt.
Add the warm water and mix until everything is combined and a sticky dough forms.
Cover and let the dough rest for 45 minutes to 1 hour, or until doubled in size.
Transfer the dough onto a lightly floured surface and gently shape it into a loaf.
Place the dough on parchment paper and transfer it into your Dutch oven.
Bake at 450°F for 45 minutes with the lid on.
Remove the lid and bake for another 15 minutes until beautifully golden brown.
Let your bread cool before slicing.
