In a stand mixer bowl, add in all the ingredients.
Knead on speed low/medium speed for 10-15 minutes using the dough hook. (Speed 4 if you are using a kitchen aid) Knead until the dough is smooth and can pass the window pane test.
Place dough into a greased bowl and cover it with plastic wrap or beeswax paper.
Allow the dough to rise overnight (8-12 hours). This will depend on your season and how cold or hot your kitchen is. The dough should double in size!
The next day, take your kitchen scale and weigh out 2oz balls of dough. It should get you between 12-14 rolls. (Weighing the rolls isn’t necessary if you don’t have a kitchen scale. However, if you do, it will help ensure a more “uniform” size amongst all the rolls.)
Take each weighed-out roll and pinch the sides together. Next, roll the balls to create tension on the counter. You can do this by cupping the dinner roll lightly in your hand and rotate against the counter to seal off the bottom of the roll.
Place the rolls into a greased 9x13” baking dish and cover with plastic wrap or a damp towel.
If you plan to bake these rolls the same day, let them rise on the counter for 1-2 hours until doubled in size.
BULK FERMENT: Another option is to let these rolls bulk ferment in the fridge for 1-2 days to allow the sourdough flavor to develop. Remove the rolls from the fridge 20-30 minutes before baking to bring them down to room temperature.
Preheat your oven to 375℉
Brush the top of the rolls with egg wash to give them a nice golden color.
Bake the rolls for 25-30 minutes or until they reach an internal temp of 190-200℉.
Top with melted butter if you heart desires. Allow to cool & enjoy!
