I use a stainless steel casserole dish 20cm diam & 10cm deep, with excellent results - a really good oven spring and an 'artisan' crust. Here's how:
'DUTCH OVEN' WHITE BREAD
500g strong bread flour
1¼ tsp fast-action yeast
1 tsp caster sugar
¾ tsp salt
¾ tbs light oil
Mix, knead & prove in proving oven 1¼ hrs. Knock back, shape into a boule on a 15" length of baking parchment. Holding the paper ends, drop into a 20cm couronne or large mixing bowl. Flour & slash top with a razor blade. 20 mins in proving oven then move to a warm place while heating oven & casserole to 200c. Leave 10 mins more to get dish really hot. Use thick gloves to remove it. Quickly drop dough & parchment into dish and if lid has holes seal it with foil. Bake 20 mins, remove lid & foil, fold parchment back to expose top. Bake 10 mins more then lift out, discard parchment and bake 10 mins more on oven rack.
