FWSY suggests baking this uncovered for 15 minutes more, but last time I did that the crust was overly dark. You can see even here it's catching on the edges.
Maybe try turning down the heat a bit when the lid is off, then the loaf gets the full bake it needs without burning. All ovens are different so yours may be hotter than advertised! Or could you bake it at a lower level in the oven?
Strange question - but do you have an oven thermometer or do you rely on the numbers on the dial? If you don't have one, it is the single best thing that will improve your baking.
