Combine 3 1/2 cups of flour, 1 teaspoon of salt and 3 tablespoons of sugar into a large mixing bowl
Whisk together 2/3 cup of water, 2/3 cup of buttermilk and 1 packet of instant yeast until the yeast dissolves
Add the yeast mixture and 3 tablespoons of melted butter into the flour mixture
Mix until a soft dough forms
Transfer the dough onto a floured work surface
Knead the dough for 3-5 minutes. The dough should feel soft and elastic, tacky, but not sticky. If the dough is sticky, add a bit more flour until it no longer feels sticky
Once you are done kneading, begin tucking the sides of the dough under to form it into a ball
Place the ball of dough into a large glass bowl that has been greased with 1 tablespoon of olive oil
Cover the bowl tightly with plastic wrap and a kitchen towel and allow it to rest for 60-90 minutes in a warm place
Once the dough has doubled in size, transfer it onto a floured work surface and roll it out into a large rectangle
Cover the entire surface of the dough with 2 cups of cheddar cheese and 1/2 cup of finely chopped herbs
Roll the dough tightly, starting on the short end (see photos above)
Cut the rolled dough in half longwise
Gather the two halves together at the top and braid the dough three times over (see photos above) and finish the braid by gathering the bottoms together neatly
Transfer the braided dough into a buttered 9"x5" loaf pan and cover it loosely with non-stick plastic wrap
Rest for 20-25 minutes or until the dough has puffed up about 1 inch over the sides of the pan
Preheat your oven to 350 degrees
Remove the plastic wrap and place the loaf onto the middle rack in your preheated oven
Bake at 350 degrees for 40-45 minutes or until the bread is deeply golden brown and the internal temperature reaches 185-190 degrees
Transfer the loaf (in the pan) onto a cooling rack and brush the crust with 1 tablespoon of melted butter
After 5 minutes, transfer the loaf out of the pan and directly onto the cooling rack
Allow the bread to cool for 60 minutes before cutting
Store in an airtight container at room temperature
