Preheat the oven to 500°F (260°C) convection bake. Place a Dutch oven inside the oven and preheat with Dutch oven inside.
Take the dough out of the fridge. Turn it out onto parchment paper or bread sling dusted with flour. Use a lame or sharp knife to score the top (a single slash works).
This cut should be about 1/2 inch deep from one end of the loaf to the next. This score helps the loaf retain a nice shape while it rises and expands in the oven.
Carefully transfer the dough into the hot Dutch oven (using parchment paper or a bread sling for easy lifting).
Reduce the heat and bake the bread at 450°F (230°C) for 40 minutes with the lid on.
Remove the lid and sprinkle the remaining cheese blend on top of the bread. Bake for another 5-10 minutes to melt the cheese and brown the crust a little bit more.
Internal temperature of loaf should read between 195-200 F.
Once the bread is baked, remove the bread from the Dutch oven and transfer to a wire rack carefully.
Melt a few Tablespoons of butter in the microwave, and then brush the crust of the loaf well with melted butter using a pastry brush (you can skip this step but I like the softness it adds to the crust).
2 Tbsp salted butter
Let the bread cool completely (at least 1-2 hours) before slicing. Cutting too soon will result in a gummy crumb because the inside is still setting!
