Heat the oven to 200C fan
Put the casserole dish in the oven to heat. (The dish needs to be warm before you put the dough in so that you don't get a soggy bottom.)
Cut a piece of parchment big enough to cover bottom and sides of casserole dish.
Sprinkle the parchment with a bit of plain flour.
Flour your hands and tip the dough onto the parchment.
Do not knead. Simply shape the dough into a round loaf.
When the oven and the casserole dish are at 200C, carefully transfer the parchement and dough to the dish. Sprinkle a few oats on top for decoration.
Cover and bake for 20 minutes.
Turn the oven down to 180C fan. Uncover bread and bake for a further 30 minutes until brown and cooked through.
Let cool slightly before slicing.
